The present invention relates to compositions comprising various vitamins and minerals and methods for using these compositions for nutritional supplementation in, for example, subjects in physiologically stressful states.
Nutrition plays a critical role in maintaining good health. Proper nutrition prevents dietary deficiencies, and also protects against the development of disease. Proper nutrition plays an increasingly important role as the body faces physiological stress. For example, pregnancy and lactation are among the most nutritionally volatile and physiologically stressful periods and processes in the lifetimes of women. Specifically, vitamin and mineral needs are almost universally increased during these natural processes. These increased needs are almost always due to elevated metabolic demand, increased plasma volume, increased levels of blood cells, decreased concentrations of nutrients, and decreased concentrations of nutrient-binding proteins.
Thus, nutritional supplementation serves a vital role in protecting against poor nutrition and disease. More specifically, research has suggested that optimizing specific nutrients before, during, and after the physiological processes of pregnancy or lactation can have a profound, positive, and comprehensive impact upon the overall wellness of the developing and newborn child as well as the safety and health of the mother. The present inventions provide compositions and methods designed to supplement the nutritional needs of individuals within physiologically stressful states.
The present invention provides compositions and methods of using these compositions for both prophylactic and therapeutic nutritional supplementation, specifically throughout physiologically stressful states.

Vitamin and mineral needs are almost universally increased throughout these periods. Increased needs during physiologically stressful states such as pregnancy or lactation, for example, may result from elevated metabolic demand, increased plasma volume, increased quantities of circulating red blood cells, decreased concentrations of nutrients, and decreased concentrations of nutrient-binding proteins such as, for example, serum-ferritin, maltose-binding protein, lactoferrin, calmodulin, tocopheryl binding protein, riboflavin binding protein, retinol binding protein, transthyretin, high density lipoprotein-apolipoprotein Al, folic acid binding protein, and 25-hydroxyvitamin D binding protein. Lapido, 72(Supp.) A
Optimizing specific nutrients before, during, and after the physiological processes of pregnancy and lactation can have a profound, positive, and comprehensive impact on the overall wellness of the developing and newborn child as well as the safety and health of the mother. Black, 85 B
The compositions and methods of the present invention provide the means to optimize good health by utilizing vitamin and mineral nutritional supplementation. The compositions and methods of the present invention may be administered to or directed to a subject such as a human or any other organism.
The compositions and methods of the present invention may comprise or use Vitamin A. This vitamin functions in physiological processes resulting in cellular differentiation, cellular maturity, and cellular specificity. Vitamin A is an important component of a nutritional supplement for subjects in a physiologically stressful state, such as pregnant or lactating women. Zile et al., 131(3) J. Nutr. 705-08 (2001). The compounds and methods of the present invention may comprise a form of Vitamin A, specifically, for example, the pro-vitamin A carotenoid beta carotene. Beta carotene is converted to Vitamin A within the body as needed. Mayne, 10 FASEB J. 690-701 (1996). The novel compositions and methods of the present invention may comprise or use Vitamin A, specifically in amounts ranging from about 2430 IU to about 2970 IU and, in a specific embodiment, around 2700 IU:
The compositions and methods of the present invention may comprise or use Vitamin D. Vitamin D is a fat-soluble “hormone like” substance important for the maintenance of healthy bones. This vitamin increases the absorption of calcium and phosphorous from the gastrointestinal tract, and improves mineral resorption into bone tissue. Vitamin D can be converted to its active form from exposure of the skin to sunlight. This fact is among the reasons why Vitamin D deficiency is common in the elderly, notably the institutionalized, who spend little or no time out of doors. Deficiencies lead to increased bone turnover and loss, and when severe, osteomalacia, or softening of the bones. Supplementation with Vitamin D has been shown to moderately reduce bone loss, increase serum 25-hydroxyvitamin D, and decrease serum parathyroid hormone levels. Dawson-Hughes et al., 337 NEW ENG. J. MED. 670-76 (1997); Lips et al., 86 J. CLIN. ENDOCRINOL. METAB. 1212-21 (2001).
The Vitamin D of the compositions and methods of the present invention may comprise Vitamin D3 (cholecalciferol). In the body, Vitamin D3 is produced when its precursor is exposed to ultraviolet irradiation (e.g., sunlight) and then hydroxylated in the liver to form 25-hydroxyvitamin D3, a form of Vitamin D in circulation. This form of the vitamin may be hydroxylated again in the kidney, yielding 1,25-hydroxyvitamin D3, a potent form of Vitamin D. Vitamin D3 plays a role in the maintenance of calcium and phosphorus homeostasis, but it is also active in cell differentiation and immune function. The novel compositions and methods of the present invention may comprise or use Vitamin D, specifically in amounts ranging from about 360 IU to about 440 IU and, in a specific embodiment, around 400 IU.
The compositions and methods of the present invention may comprise or use Vitamin C (also known as ascorbic acid). The major biochemical role of the water-soluble Vitamin C is as a co-substrate in metal catalyzed hydroxylations. Vitamin C has antioxidant properties in interacting directly with superoxide hydroxyl radicals and singlet oxygen. Vitamin C also provides antioxidant protection for folate and Vitamin E, keeping Vitamin E in its most potent form.
Lipid peroxidation has been associated with over 200 disease processes. Rock et al., 96(7) J. AMER. DIET. ASSOC. 693-702 (1996). Specifically, lipid peroxidation may be implicated, for example, in the pathophysiology of preeclampsia, a toxemia of pregnancy. Vitamin C may afford protective effects against preeclampsia by participating in the scavenging of free radicals. Indeed, significantly lower levels of Vitamin C have been observed in preeclamptic women than in controls. Woods et al., 185(1) AM. J. OBSTET. GYNECOL. 5-10 (2001); Kharb, 1 EURO. J. OBSTET. GYNECOL. REPROD. BIOL. 37-39 (2000); Milczarek et al., 210 MOL. CELL. BIOCHEM. 65-73 (2000).
Vitamin C also enhances the absorption of iron. NATIONAL RESEARCH COUNCIL, RECOMMENDED DIETARY ALLOWANCES 115 (10th ed. 1989) (hereinafter “RDA”). In addition, Vitamin C is required for collagen synthesis, epinephrine synthesis, and bile acid formation. Moreover, Vitamin C has been implicated in inhibiting atherosclerosis by being present in extracellular fluid of the arterial wall and potentiating nitric oxide activity, thus normalizing vascular function. The novel compositions and methods of the present invention may comprise or use Vitamin C, specifically in amounts ranging from about 63 mg to about 77 mg and, in a specific embodiment, around 70 mg.
The compositions and methods of the present invention may comprise or use Vitamin E. Vitamin E is a fat-soluble vitamin antioxidant found in biological membranes where it protects the phospholipid membrane from oxidative stress. One form of Vitamin E, dl-alpha-tocopheryl acetate (BASF Corporation, Mount Olive, N.J.), is used to fortify foods and pharmaceuticals and may be used within the context of the present invention. Vitamin E inhibits the oxidation of unsaturated fatty acids by trapping peroxyl free radicals. It is also an antiatherogenic agent, and studies have demonstrated a reduced risk of coronary heart disease with increased intake of Vitamin E. Stampfer et al., 328 NEW ENG. J. MED. 1444-49 (1993). In addition, Vitamin E, like Vitamin C, may afford protective effects against preeclampsia by participating in the scavenging of free radicals. Indeed, significantly lower levels of Vitamin E have been observed in preeclamptic women than in controls. Woods et al., 185(1) AM. J. OBSTET. GYNECOL. 5-10 (2001); Kharb, 1 EURO. J. OBSTET. GYNECOL. REPROD. BIOL. 37-39 (2000); Milczarek et al., 210 MOL. CELL. BIOCHEM. 65-73 (2000). The novel compositions and methods of the present invention may comprise or use Vitamin E, specifically in amounts ranging from about 27 IU to about 33 IU and, in a specific embodiment, around 30 IU.
The compositions and methods of the present invention may comprise or use B-complex vitamins. This class of vitamins comprises the water-soluble nutrients not generally stored in the body. The B-complex vitamins of the present compositions and methods may comprise one or more of thiamine (B1), riboflavin (B2), niacin (B3), folic acid, pyridoxine (B6) and cyanocobalamin (B12). B-complex vitamins play roles in a variety of biological processes critical to the health of pregnant women, lactating women, and fetuses such as, for example, the metabolism of homocysteine.
The compositions and methods of the present invention may comprise or use folic acid. The B-complex vitamin folic acid has demonstrated the ability to prevent neural tube defects such as spina bifida caused by disturbed homocysteine metabolism. Vanderput et al., E
The compositions and methods of the present invention may comprise or use Vitamin B1. This vitamin plays a role in carbohydrate metabolism and neural function. It is a coenzyme for the oxidative decarboxylation of alpha-ketoacids (e.g., alpha-ketoglutarate and pyruvate) and for transketolase which is a component of the pentose phosphate pathway. Folate deficiency and malnutrition inhibit the activity of thiamine. RDA at 123. Vitamin B1 is available in forms known to those of skill in the art, including the form of thiamine mononitrate (BASF Corporation, Mount Olive, N.J.). The novel compositions and methods of the present invention may comprise or use Vitamin B1, specifically in amounts ranging from about 1.44 mg to about 1.76 mg and, in a specific embodiment, around 1.6 mg.
The compositions and methods of the present invention may comprise or use Vitamin B2 (riboflavin). Riboflavin is a component of two flavin coenzymes, flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). These flavoenzymes are involved in a number of oxidation-reduction reactions including the conversion of pyridoxine and niacin. RDA at 132. Flavoenzymes also play a role in a number of metabolic pathways such as amino acid deamination, purine degradation, and fatty acid oxidation and thus help to maintain carbohydrate, amino acid, and lipid metabolism. The novel compositions and methods of the present invention may comprise or use Vitamin B2, specifically in amounts ranging from about 1.62 mg to about 1.98 mg and, in a specific embodiment, around 1.8 mg.
The compositions and methods of the present invention may comprise or use Vitamin B6 (pyridoxine). The administration of pyridoxine may reduce the levels of homocysteine. Bostom et al., 49 KIDNEY INT. 147-52 (1996). The active forms of pyridoxine, pyridoxal-5′-phosphate (PLP) and pyridoxamine-5′-phosphate, are coenzymes for numerous enzymes and as such, are important for gluconeogenesis, niacin formation, and erythrocyte metabolism. RDA at 14243. Pyridoxine is a coenzyme for both cystathionine synthase and cystathionase, enzymes that catalyze the formation of cysteine from methionine. Homocysteine is an intermediate in this process and elevated levels of plasma homocysteine are recognized as a risk factor for both vascular disease (Robinson et al., 94 CIRCULATION 274348 (1996)) and neural tube defects (Locksmith & Duff, 91 OBSTET. GYNECOL. 1027-34 (1998)). Vitamin B6 is available in forms known to those of skill in the art, including the form of pyridoxine hydrochloride (BASF Corporation, Mount Olive, N.J.). The novel compositions and methods of the present invention may comprise or use Vitamin B6, specifically in amounts ranging from about 2.25 mg to about 2.75 mg and, in a specific embodiment, around 2.5 mg.
The compositions and methods of the present invention may comprise or use Vitamin B12. Cobalamin (a form of Vitamin B12) can be converted to the active coenzymes, methylcobalamin and 5′-deoxyadenosylcobalamin. These coenzymes are necessary for folic acid metabolism, conversion of coenzyme A, and myelin synthesis. For example, methylcobalamin catalyzes the demethylation of a folate cofactor which is involved in DNA synthesis. A lack of demethylation may result in folic acid deficiency. RDA at 159-60. Deoxyadenosylcobalamin is the coenzyme for the conversion of methylmalonyl-CoA to succinyl-CoA, which plays a role in the citric acid cycle. Importantly, cobalamin, along with pyridoxine and folic acid in implicated in the proper metabolism of homocysteine. Cobalamin is available as cyanocobalamin, methylcobalamin, hydroxocobalamin, adenosylcobalamin, and hydroxycyanocobalamin. The novel compositions and methods of the present invention may comprise or use Vitamin B12, specifically in amounts ranging from about 10.8 mcg to about 13.2 mcg and, in a specific embodiment, around 12 mcg.
The compositions and methods of the present invention may comprise or use niacin. Niacin, also called Vitamin B3, is the common name for two compounds: nicotinic acid (also called niacin) and niacinamide (also called nicotinamide). Niacin is particularly important for maintaining healthy levels and types of fatty acids. Niacin is also required for the synthesis of pyroxidine, riboflavin, and folic acid. RDA at 137. Administration of niacin may also effect a reduction in total cholesterol (LDL) and very low density lipoprotein (VLDL) levels and an increase in high density lipoprotein (HDL) cholesterol levels. Nicotinamide adenine dinucleotide (NAD) and NAD phosphate (NADP) are active coenzymes of niacin. These coenzymes are involved in numerous enzymatic reactions such as glycolysis, fatty acid metabolism, and steroid synthesis. Henkin et al., 91 AM. J. MED. 239-46 (1991). The novel compositions and methods of the present invention may comprise or use niacin, specifically in amounts ranging from about 16.2 mg to about 19.8 mg and, in a specific embodiment, around 18 mg.
Minerals are inorganic, or non-carbon-containing, elements that are critical for healthy physiological processes. Minerals are contemplated in the compositions and methods of the present invention. Such minerals may be in either chelated or non-chelated form. For example, minerals act as cofactors for hundreds of enzymes associated, for example, with food digestion, nucleic acid production, and protein synthesis. Minerals may also act as, for example, cofactors for antioxidant enzymes. The minerals of the compositions and methods of the present invention may comprise one or more of calcium, iron, magnesium, zinc, and copper.
The compositions and methods of the present invention may comprise or use calcium in either chelated or non-chelated form. Chelation of calcium may affect its bioavailability. This mineral is required for proper functioning of numerous intracellular and extracellular processes including, for example, muscle contraction, nerve conduction, blood coagulation, and of particular interest in the context of pregnancy and lactation, hormone release. In addition, the calcium ion plays a unique role in intracellular signaling and is involved in the regulation of many enzymes. T
The compositions and methods of the present invention may comprise or use iron in either chelated or non-chelated form. Chelation of iron may affect its bioavailability. A primary function of iron is to carry oxygen to bodily tissues via the hemoglobin part of red blood cells. Supplemental intake of iron is critical to preventing anemia, a disorder associated with a variety of physiological states including, for example, pregnancy. Bothwell, 72(Supp.) AM. J. CLIN. N
The compositions and methods of the present invention may comprise or use magnesium in either chelated or non-chelated form. Chelation of magnesium may affect its bioavailability. Magnesium is important for over 300 different enzyme reactions. A primary function of magnesium is to bind to phosphate groups in adenosine triphosphate (ATP), thereby forming a complex that assists in the transfer of ATP phosphate. Magnesium also functions within cells as an allosteric activator of enzyme activity and for membrane stabilization. Magnesium also plays roles in nucleic acid synthesis, transcription of DNA and RNA, amino acid activation, and protein synthesis. JAMES L. L. GROFF ET AL., ADVANCED NUTRITION AND HUMAN METABOLISM 341 (2d ed. 1996).
Magnesium is found primarily in both bone and muscle. Magnesium is related to the reactions of over 300 enzymes, including enzymes associated with biosynthetic pathways, glycolysis, protein synthesis, transketolase reactions, and membrane transport. Magnesium is also involved in the formation of cAMP, a cytosolic second messenger that plays a role in cell signaling mechanisms. In addition, magnesium functions both synergistically and antagonistically with calcium in neuromuscular transmission. RDA at 188. Specifically, magnesium is critical for the maintenance of electrochemical potentials of nerve and muscle membranes and the neuromuscular junction transmissions, particularly important in the heart. Not surprisingly, magnesium deficiency is tied to cardiovascular disease and hypertension. Agus et al., 17 CRIT. CARE CLINICS 175-87 (2001). Indeed, oral magnesium therapy improves endothelial function in patients with coronary disease. Shechter et al., 102 CIRCULATION 2353-58 (2000).
Magnesium is available in a variety of salts. One form of magnesium known in the art is magnesium oxide (Mallinckrodt Baker, Inc., Phillipsburg, N.J.). The novel compositions and methods of the present invention may comprise or use magnesium, specifically in amounts ranging from about 22.5 mg to about 27.5 mg and, in a specific embodiment, around 25 mg.
The compositions and methods of the present invention may comprise or use zinc in either chelated or non-chelated form. Chelation of zinc may affect its bioavailability. Zinc plays a role in numerous metabolic activities such as nucleic acid production, protein synthesis, and development of the immune system. There are more than 200 zinc metalloenzymes including aldolase, alcohol dehydrogenase, RNA polymerase, and protein kinase C. Zima et al., 17 BLOOD PURIF. 182-86 (1999). Zinc stabilizes RNA and DNA structures, forms zinc fingers in nuclear receptors, and is a component of chromatin proteins involved in transcription and replication. Deficiencies of zinc during pregnancy have been shown to contribute to severe fetal abnormalities. Srinivas et al., 68(6) INDIAN J. PEDIATR. 519-22 (2001); Yang et al., 13(4) BIOMED. ENVIRON. SCI. 280-86 (2000); King, 71(Supp.) A
The compositions and methods of the present invention may comprise or use copper in either chelated or non-chelated form. Chelation of copper may affect its bioavailability. Copper is an important component of the process of gene expression. Deficiencies of copper may lead to anemia, neutropenia, and bone abnormalities in pregnant and lactating women. In addition, a fetus must accumulate copper at a rate of 50 μg×kg−1×d−1 over the latter half of pregnancy; any deficiency in accumulation may lead to low birth weight and protein-energy malnutrition. Uauy et al., 67(Supp.) A
The compositions and methods of the present invention may comprise or use a combination of vitamins and minerals, in either chelated or non-chelated form, that work together with various metabolic systems and physiological responses of the human body. The active ingredients are available from numerous commercial sources, and in several active forms or salts thereof, known to those of ordinary skill in the art. Hence, the compositions and methods of the present invention are not limited to comprising or using any particular form of the vitamin or mineral ingredient described herein.
The ingredients of the present invention may be combined into a composition which may be in the form of a solid powder, caplets, tablets, lozenges, pills, capsules, or a liquid, and which may be administered alone or in suitable combination with other components. For example, the composition of the present invention may be administered in one or more caplets or lozenges as practical for ease of administration. Each of the vitamins and minerals is commercially available, and can be blended to form a single composition or can form multiple compositions, which may be co-administered.
To prepare the compositions of the present invention, each of the active ingredients may be combined in intimate admixture with a suitable carrier according to conventional compounding techniques. The carrier may take a wide variety of forms depending upon the form of the preparation desired for administration, e.g., oral, sublingual, nasal, via topical patch, or parenteral. The composition may consist of one to three caplets or lozenges, the composition of each preferably being identical to each other caplet or lozenge.
In preparing the composition in oral dosage form, any usual media may be utilized. For liquid preparations (e.g., suspensions, elixirs, and solutions), media containing, for example water, oils, alcohols, flavoring agents, preservatives, coloring agents and the like may be used. Carriers such as starches, sugars, diluents, granulating agents, lubricants, binders, disintegrating agents and the like maybe used to prepare oral solids (e.g., powders, caplets, pills, tablets, capsules, and lozenges). Controlled release forms may also be used. Because of their ease in administration, caplets, tablets, pills, and capsules represent the most advantageous oral dosage unit form, in which case solid carriers are employed. If desired, tablets may be sugar coated or enteric coated by standard techniques. All of these pharmaceutical carriers and formulations are well known to those of ordinary skill in the art. See generally, e.g., W

Without further elaboration, it is believed that one skilled in the art, using the preceding description, can utilize the present invention to the fullest extent. The following examples are illustrative only, and not limiting of the remainder of the disclosure in any way whatsoever.
A composition of the following formulation was prepared in caplet form, including the appropriate excipients, by standard methods known to those of ordinary skill in the art:
A study is undertaken to evaluate the effectiveness of the composition of the present invention in the treatment of patients. The objective of the study is to determine whether oral intake of the composition results in an improvement of the nutritional status of a patient in a physiologically stressful state.
A double-blind, placebo controlled study is conducted over a six-month period. A total of 120 subjects (60 pregnant women entering the second trimester of pregnancy and 60 lactating women), aged 20-35 years, are chosen for the study. An initial assessment of the nutritional status of each woman is conducted utilizing methods such as the peroxide hemolysis test to assess Vitamin E deficiency, measurement of erythrocyte transketolase activity to determine thiamine levels, determination of erythrocyte glutathione reductase activity to assess riboflavin status, and high performance liquid chromatography to directly measure pyridoxine levels.
The 120 subjects are separated into four separate groups of 30 women. In a first group comprising only pregnant women and in a second group comprising only lactating women, each subject is administered 2 caplets, daily, of the composition as described in Example 1. In a third group comprising only pregnant women and in a fourth group comprising only lactating women, each subject is administered 2 placebo caplets, daily. No other nutritional supplements are taken by the subjects during the assessment period.
An assessment of the nutritional status of each woman is conducted utilizing methods such as the peroxide hemolysis test to assess Vitamin E deficiency, measurement of erythrocyte transketolase activity to determine thiamine levels, determination of erythrocyte glutathione reductase activity to assess riboflavin status, and high performance liquid chromatography to directly measure pyridoxine levels at one month intervals for a six month period. The data is evaluated using multiple linear regression analysis and a standard t-test. In each analysis, the baseline value of the outcome variable is included in the model as a covariant. Treatment by covariant interaction effects is tested by the method outlined by Weigel & Narvaez, 12 C
A statistically significant improvement in the nutritional status with respect to Vitamin E, thiamine, riboflavin, and pyridoxine is observed in the treated subjects upon completion of the study over the controls. Therefore, the study confirms that oral administration of the composition of the present invention is effective in improving the nutritional status of a patient within a physiologically stressful state.
While there has been described what is presently believed to be the preferred embodiments of the present invention, other and further modifications and changes may be made without departing from the spirit of the invention. All further and other modifications and changes are included that come within the scope of the invention as set forth in the claims. The disclosure of all publications cited above are expressly incorporated by reference in their entireties to the same extent as if each were incorporated by reference individually.
The present application is a continuation of and claims, under 35 U.S.C. § 120, the benefit of U.S. patent application Ser. No. 10/315,159, filed 10 Dec. 2002, now U.S. Pat. No. 6,814,983 which is expressly incorporated fully herein by reference.
