We live in an aging society. Baby boomers, those born between 1946-1964 are the second largest age group, at an estimated 73 million. It is within this age group that people are concerned with and possibly dealing with the effects of aging, including changes relating to cognitive abilities. As people age, the brain naturally changes, affecting memory, learning, and other cognitive functions. Many older adults worry about losing cognitive abilities, including memory loss and the ability to learn and think as they age. Declining mental abilities, including the occurrence of Alzheimer's disease and dementia, are also becoming more and more of a concern as the population ages. Therefore, improving cognition, which is defined as the combination of several critical brain functions, including memory, judgment, language, intuition and the ability to learn, has come to the forefront of medicine and research. Research and development of new drugs to combat these signs of aging, including cognitive decline and brain health to hopefully slow down the aging process of the brain are at the forefront of the medical community. Additionally, cognitive health improvements and support may also be beneficial for school age children. And further, millennials who see the cognitive decline in their parents are looking for dietary solutions they can start now so as to have a beneficial effect in years to come.
In addition to traditional pharmaceuticals, there is also a growing interest in dietary or nutritional supplements and nutritional foods and beverages for the treatment of various health issues. More natural-based supplements, including gluten-free, vegetarian/vegan-based products, Non-GMO Project Verified, and Kosher & Halal certified are likewise entering the cognition support and brain health market.
For example, lutein is a carotenoid that has been shown to support vision health, and the combination of lutein and zeaxanthin are best known for eye health. However, more recently lutein and zeaxanthin have shown promise for cognitive health as well. Studies have shown that lutein and zeaxanthin can benefit all ages, from school age children to older adults. Ingredients geared toward gamers (avid video game players) have also been gaining popularity in the market. Gamers need both strong eyes and cognitive dexterity, lutein and lutein:zeaxanthin are becoming the choice ingredients for gamer support formulas. Applicant's product, Optilut® lutein esters and XanMax® free lutein: zeaxanthin complex dietary ingredients, have been designed to follow the cognitive health benefits.
Furthermore, there are initial indications that lutein esters, which is the form naturally available in plants, is more bioavailable than free lutein. See for example: https://cdn.technologynetworks.com/ep/pdfs/lutein-esters-are-more-bioavailable-than-free-lutein. pdf, which is authored by the present inventor. Bioavailability is an important measure of the efficacy of dietary ingredients. Therefore, it would be anticipated that lutein esters are a preferred choice for cognitive support over free lutein.
Withania somnifera Dunal (WS) of family Solanaceae, known as Ashwagandha in Ayurveda, the ancient Hindu system of medicine, has been in use for centuries for treating various ailments. Ashwagandha is an adaptogen. Adaptogens mimic the body's own stress reducing hormones and increase the body's ability to recover from stress while creating an overall feeling of balance and normalization. Additionally, studies have shown than ashwagandha may be useful for improving memory and cognitive functions. See, Choudhary D., Bhattacharyya S., Bose S., Efficacy and Safety of Ashwagandha (Withania somnifera (L.) Dunal) Root Extract in Improving Memory and Cognitive Functions, J Diet Suppl. 2017 Nov. 2; 14(6):599-612.
Additionally, there are numerous products in the market containing ashwagandha. One such product offered by the present Applicant is Shoden®, which is a clinically-tested, purified extract from the leaves and roots of the Ashwagandha plant. With an industry leading 35% Withanolide Glycosides (measured by HPLC), Shoden® offers high bioavailability and guaranteed activity even at low doses. Ashwagandha is believed to offer a variety of functions and benefits, including:

Additional features and advantages of the present disclosure are described in, and will be apparent from, the detailed description of the presently preferred embodiments.
The present disclosure relates to an improved dietary supplement composition formulated in a therapeutic effective amount to enhance cognitive skills and maintain brain health. The composition is believed to produce a brain maintenance effect by shielding against the impact of aging on cognitive performance, as well as potentially enhance cognitive abilities for memory enhancement, learning and gaming. The present disclosure relates to providing a formula for oral consumption, in the form of a dietary supplement. The ingredients used in the present composition are food or dietary ingredients, and do not include chemicals or drugs that are not suitable for human/animal consumption as foods or dietary supplements. The disclosure further relates to a method of supporting cognitive health in a mammal is provided, comprising orally administering to the mammal in need thereof, a therapeutically effective amount of an improved dietary supplement composition formulated to support cognitive skills and brain health, wherein the composition is administered daily.
It is a key embodiment of the present disclosure that the broad-spectrum compositions consist of dietary ingredients which have a positive effect on cognitive support and brain health. It is these particular functionalities that make the present dietary supplement composition unique. Additionally, it is a unique feature of the present composition to include ingredients that improve brain wave function, a physical manifestation of improved cognitive function, as well as improve neurotransmission, a chemical manifestation of improved cognitive function.
The first ingredient in the present composition is a carotenoid, which are generally in two categories—xanthophylls and carotenes. Xanthophylls include lutein, astaxanthin, zeaxanthin, etc. Lutein can be either free or ester forms. Naturally occurring lutein esters extracted from marigold flowers are not just one ester but a family of naturally occurring esters. They include mono- and di-esters. The main ester is lutein dipalmitate, but there are also smaller amounts of other esters such as palmitate, laurate, dilaurate, stearate, distearate, myristate and dimyristate esters. An extract of lutein esters may also include trans-zeaxanthin, a naturally occurring zeaxanthin.
In a preferred embodiment of the present disclosure, lutein esters are used, which as discussed above, has been shown to be more highly available than free ester. In a present composition, lutein esters are provided in a range of about 10-80 mg per day, which converts in a body to approximately 50% free lutein, with a free lutein range of 10-40 mg. In another embodiment of the present composition, lutein esters are provided in a range of about 20-50 mg per day, which converts in the body to approximately 50% free lutein, with a free lutein range of 10-25 mg. In another embodiment of the present composition, free lutein esters are provided in a range of about 10-25 mg per day, which coverts in the body to approximately 50% free lutein, with a free lutein range of 5-12.5 mg. As discussed above, there is new evidence that lutein plays a role in cognitive improvement, and therefore will work synergistically in the present formula.
The second ingredient of the present composition is an adaptogen, which improves brain health, reduces stress and anxiety, increases calm and relaxation, improves sleep ability, restores balance and improves physical performance. An adaptogen is an herb that has hormonal-like activity and protects the body against stress and other insults. Adaptogens are also known as phytohormones—i.e., plant extracts with hormonal-like activity. Adaptogens include but are not limited to rhodiola, ashwagandha, ginseng, astragalus, cordyceps, eleuthero, tulsi, turmeric, etc.
In the present composition, ashwagandha is the preferred adaptogen. Ashwagandha has the unique ability to help maintain homeostasis during intense stress, which is exactly what is needed by gainers to balance their performance. It is also believed that ashwagandha is useful for improving memory and cognitive functions, which are important attributes for the present composition. Ashwagandha is an Indian Ayurvedic herb also known as Indian ginseng, poison gooseberry, or winter cherry, and is also known by its Latin name Withania somnifera. Ashwagandha extract containing at least 5% withanolides (the bioactive components of Ashwagandha) with at least 35% glycowithanolides even more preferred. Preferred dosages for ashwagandha extract are between 60 mg and 600 mg per day, with more preferred dosages between 60 and 300 mg per day, with further preferred dosages between 60 and 120 mg per day. Ashwagandha extract bioavailability is high and effects can be felt within a few days making it a suitable selection for the present composition.
The present dietary supplement composition can be in any suitable delivery form including beadlets, pills (capsules, tablets, softgels, lozenges, chewables), gummies, powders for mixing to form beverages, ready to drink (RTD) beverages, or in foods such a snack bars, cookies or other food forms. Examples of compositions useful in the present disclosure include; lutein esters powders combined with ashwagandha extract powders; ashwagandha extract powder dispersed in lutein esters oil, with or without a dispersion agent; and, ashwagandha extract powder combined with encapsulated lutein esters oils.
In order to formulate these forms of oral consumables, there typically is the need to include inert ingredients. Inert ingredients do not perform any biological function, but instead help create the final form of the product suitable for consumption. Types of inert ingredients include fillers, coatings, lubrication aids, flow agents, binders, preservatives, flavors, fragrances, viscosity modifiers etc. The final product supplement, food or beverage may include any or all of these excipients as necessary to form the product, and it should be noted are not limited to these items listed.
In a most preferred embodiment, the delivery form of the present composition would be a unique single particle combination of the two ingredients, such as in a beadlet. This is a form distinct from a physical blend of the two ingredients. It is believed that the single particle combination product, which brings the two ingredients, for example lutein esters and ashwagandha extract—together in close proximity, results in a synergistic effect on cognitive health. Notwithstanding this preferred embodiment, other embodiments consisting of either a physical blend powders of the two ingredients, or combinations of oils and powders, are also preferred.
The present disclosure also relates to a method of supporting cognitive health in a mammal. “Mammal” may refer to humans, as well as, to animals and pets in particular. There is a growing market for supporting cognition and brain health in pets. A leading dog food manufacturer offers a senior dog food that is promoted as enhancing alertness and cognitive health in aging dogs. Therefore, the composition of the present disclosure may be offered in a therapeutically effect amount to enhance cognitive skills and brain health in animals, particularly pets such as cats, dogs, horses, etc. The dosages of ingredients would be ratioed depending in the weight of the particular animal. For example, the dosages described herein are generally designed for human use, with a reference human weight 100 kg. Thus, in comparison, for a 20 kg dog for example, the dosage is about ⅕ of the human dosages. Dosages and amounts of the present ingredients can be modified and changed to accommodate a variety of mammals.
The following are an explanation and results of usage trials utilizing combinations of the above ingredients in a dietary supplement useful for enhancing cognitive support and brain health. Studies were conducted to evaluate the effectiveness of the following formulations:

Formula 2 includes the following concentration of ingredients: Ashwanganda: 33-35%; Lutein Esters concentrate: 14-18%; Modified food starch: 30-35%; Polysorbate: 3-5%; Acacia: 5-8%; Sugar: 2-4%; Fatty acid esters: 1-2%; and Tocopherols: 0.3%. Beadlets of Formula 2 were prepared using known methods as described above for Formula 1.
Formula 3—A dietary supplement formulation having 40 mg Opitlut® lutein esters and 60 mg Shoden® ashwagandha extract, was prepared. Formula 3 includes the following concentration of ingredients: Ashwanganda: 22%; Lutein Esters concentrate: 18%; Acacia: 20%; Microcrystalline cellulose: 25%; Sucrose 14.5%; and d-alpha Tocopherols: 0.5%. Beadlets of Formula 3 were prepared using known methods as described above for Formula 1.
Formula 4—A dietary supplement formulation having 40 mg Opitlut® lutein esters and 120 mg Shoden® ashwagandha extract, was prepared. Formula 4 includes the following concentration of ingredients: Ashwanganda: 35%; Lutein Esters concentrate: 15%; Acacia: 20%; Microcrystalline cellulose: 20%; Sucrose 9.5%; and d-alpha Tocopherols: 0.5%. Beadlets of Formula 3 were prepared using known methods as described above for Formula 1.
Trial Procedure and Data—In order to test the effects of the combination of ingredients on cognitive activity, two sets of experiments on mice were conducted. In the first set of experiments, test substances were administered orally to 8 animals in each group for 10 days. On the 10th day, the mice were evaluated for spatial learning by the T-Maze test, which is a simple maze used in animal cognition experiments. A risk assessment index was determined according to the formula−Risk Assessment Index=(frequency of tries)/(frequency of tries+Open Arm Entry). In the second set, the same procedure was used, however a pole climbing test was administered. The average of shock avoidance plus mistakes was determined (measured in seconds). For both sets of experiments, beadlets of Formula 3 and Formula 4 were tested, in addition to a placebo beadlet consisting of all the non-active ingredients in the formula (40% acacia, 40% microcrystalline cellulose, 19% sucrose, 1% d-alpha tocopherols). The results are shown in Table 1 below:
The results show that cognitive abilities as measured by the T-Maze test and the Pole Climbing test improved with the combination of lutein and ashwagandha, and also improved with increasing dose of ashwagandha in the combination.
