## Background
FIELD OF THE DISCLOSURE
The present invention generally relates to a nutritional supplement and method for enhancing weight gain of a mammal, particularly to a nutritional supplement made from Echinacea extracts which increases the appetite and slows the metabolism of the mammal by activating cannabinoid receptor type 1 of the mammal.
BACKGROUND
While the obesity epidemic is spreading at an alarming rate in the modern world especially in the developed countries, there are also a segment of individuals suffering from underweight which get far less attention. Not only will serious underweight create undesirable appearance, it may also result from eating disorders, digestive disorders and depression.
The American Dietetic Association (ADA) defines the ideal body mass index (BMI) as between 20 and 25. Anyone below that range would be considered underweight and those with a BMI from 18.5 and below extremely underweight. The ability for a person to gain or lose weight depends primarily on the person's intake of calories. Calories are found in food. However, the calories in food come in different forms: carbohydrates, fats, and protein. These different forms, known as “macronutrients,” have different effects on the body and its ability to gain weight.
When the person eats more calories than his or her body burns, the extra calories get stored for future use in the form of muscle or fat tissue. Conversely, when the person eats fewer calories than his or her body burns, the person's body taps into stored muscle and fat tissue to get the energy it needs. As a result, a major cause for certain individuals to find gaining weight difficult is a weak appetite or fast metabolism, in addition to eating irregularly due to work, or eating healthy food having low caloric density.
Conventionally, people who tried to gain weight took commercial weight gain shakes as a convenient source of calories. However, high calorie shakes are very filling and may prevent these people from enjoying regular meals by blunting their appetite, causing them to eat little or no food later in the day and resulting in little or no change in body weight.
There are also literatures suggesting that taking multivitamin supplements can improve a person's weight gain. However, such a method is only effective when the person's capability of gaining weight was being affected by certain nutrient deficiencies. People who are not deficient in given nutrients will often find this method ineffective in gaining weight. In fact, most recent research suggests that multivitamin supplementation has no effect on body weight in the general population or that it may actually prevent weight gain. See, e.g., Major, G. C., “Multivitamin and dietary supplements, body weight and appetite: results from a cross-sectional and a randomized double-blind placebo-controlled study” The British journal of nutrition, 5, 1157-1167 (2007); Nachtigal, M. C., “Dietary supplements and weight control in a middle-age population. Journal of alternative and complementary medicine” (New York, N.Y.), 5, 909-915 (2005).
Despite the foregoing efforts to improve weight gain for individuals, conventional methods are not ideally suited for everyone. Accordingly, there exists a need for improved method and formulation for enhancing weight gain which obviates the deficiency of conventional methods.

Minerals such as zinc and magnesium can optionally be added to the nutritional supplement to provide even better effect.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.
DETAILED DESCRIPTION OF THE INVENTION
The following description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the following claims. Various inventive features are described below that can each be used independently of one another or in combination with other features.
For purposes of the present disclosure, terms “CB1” and “CB2” should mean cannabinoid receptor type-1 and type-2 respectively. The cannabinoid receptor type-1 and type-2, often abbreviated as CB1 and CB2 respectively, have been identified as biological receptors of mammals. CB1 receptors are expressed in neurons of the central and peripheral nervous system. CB2 receptors are found almost exclusively in peripheral immune cells. The CB1 receptor has been found to be active in several areas of the body known to stimulate eating behavior. CB1 activation has powerful effects on food intake, energy balance, and metabolism. Activity at the receptor is critical for regulation of energy homeostasis and food intake. CB1 receptors in the brain and periphery have already been targeted as a treatment for obesity. The pharmaceutical drug rimonabant, which was FDA approved in 1996, was found to effectively reduce food intake and decrease body weight by blocking activity at the CB1 receptor as a competitive antagonist. In contrast, activation of the CB1 receptor by the endocannabinoids or by exogenous phytocannabinoids are well established to produce stimulatory effects on appetite, food intake, and weight gain. The term “Echinacea extract” or “Echinacea constituent” generally refers to alkamide or isobutylamide compound extracted or derived from Echinacea species.
Broadly, embodiments of the present invention generally provide method and nutritional supplement for enhancing weight gain of a mammal by activating CB1 of the mammal. Specifically, the present invention achieved its purpose by administering to the mammal an effective amount of alkamide compound, isobutylamide compound or combination thereof derived, extracted, or prepared from Echinacea species that are CB1 receptor agonist.
It was observed that Echinacea alkamides are structurally similar to the endocannabinoid AEA. Subsequent cannabinoid receptor binding studies have confirmed that all of the alkamides in Echinacea have affinity for the CB1 receptor at micromolar (μM) dissociation constants. The endocannabinoid system is a target for alkamides from Echinacea species. While the alkamides in Echinacea species have been shown to bind to CB1 receptors, and while CB1 activation has been implicated generally in appetite and metabolic regulation, no published studies or academic papers could be located in which alkamides were suggested or examined as a therapeutic target for the treatment of anorexia (insufficient appetite) or underweight.
The pharmacokinetic properties of the alkamides in Echinacea have been examined. Experiments show that the alkamides are detectable in human blood within 10 minutes of oral application. Time to peak concentration varied from 20-30 minutes. Orally ingested Echinacea preparations are capable of providing bioavailable alkamides for bioactivity at the CB1 receptor.
The alkamide or isobutylamide compounds extracted from Echinacea species that are found to be effective in activating CB1 include, but are not limited to, Dodeca-2E,4E,8Z,10E/Z-tetraenoic acid isobutylamides; Dodeca-2E,4Z-diene-8,10-diynoic acid isobutylamide; Undeca-2Z,4E-diene-8,10-diynoic acid isobutylamide; Undeca-2-ene-8,10-diynoic acid isobutylamide; Dodeca-2E,4E-dienoic acid isobutylamide; Dodeca-2E-ene-8,10-diynoic acid 2-methylbutylamide; Dodeca-2E,4E,8Z-trienoic acid isobutylamide; Pentadeca-2E,9Z-diene-12,14-diynoic acid isobutylamide; and Dodeca-2E,4Z-diene-8,10-diynoic acid isobutylamide.
These alkamide or isobutylamide compounds can be extracted or otherwise derived from the aerial parts, but ideally the roots, rhizomes or vegetative stems of Echinacea species (plants) such as Echinacea angustifolia, Echinacea atrorubens, Echinacea laevigata, Echinacea pallida, Echinacea paradoxa, Echinacea purpurea, Echinacea sanguinea, Echinacea simulate and Echinacea tennesseensis. For example, Dodeca-2E,4E,8Z,10E/Z-tetraenoic acid isobutylamides; Dodeca-2E,4Z-diene-8,10-diynoic acid isobutylamide; and Undeca-2Z,4E-diene-8,10-diynoic acid isobutylamide can be derived from Echinacea purpurea and Undeca-2-ene-8,10-diynoic acid isobutylamide and Dodeca-2E,4E-dienoic acid isobutylamide can be derived from Echinacea augustifolia. 
The alkamide or isobutylamide compounds derived from Echinacea species are highly unsaturated compounds. Therefore, they are prone to oxidation. Many of the alkamides in Echinacea species contain one or two alkyne moieties, which are susceptible to degradation at higher temperature and oxygen levels. The medium-chained hydrocarbon portion of these alkamides contains one or more double bonds, and some alkamides have one or two acetylene bonds. None of the alkamides are saturated. As a result, alkamides should be prone to oxidation, especially in an environment rich in oxygen. It has been suggested that Echinacea roots should be left intact or the extracts be kept in solution to prevent the oxidative breakdown of the diene structures. One study found a 13% reduction in alkamide content of ground roots over 2 months. Another study of ground roots found that after 7 months, there was a reduction in alkamide content of 88% at 25° C. and 95% at 40° C. Another observed alkamide reduction in dried, crushed Echinacea stored in the light at 20° C. or in the dark at 30° C. over a period of 60 days.
The stability of the alkamide constituents of Echinacea is very important because the medicinal properties are determined by the biological viability of those constituents. One study proposed that another class of constituents in Echinacea known as the phenolics may act as antioxidants to decrease the degradation of alkamides in a dry extract. However, no published studies or academic papers could be located in which alkamides from Echinacea were preserved or proposed to be preserved by the addition of an antioxidant.
Thus, in one embodiment of the present invention, antioxidant is used with Echinacea-derived alkamides or isobutalamides to curtail the rate of oxidation and to decrease the rate of degradation, thus increasing shelf life and alkamide potency. The antioxidant that can be used includes, but is not limited to, alpha tocopherol (vitamin E), butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), ascorbyl palmitate, propyl gallate, dodecyl gallate, ethyl gallate, and octyl gallate.
Alternatively, in another embodiment of the present invention, a unique ternary blend of antioxidant consisting of lecithin, vitamin C and vitamin E is disclosed for Echinacea-derived alkamides or isobutalamides. The ternary blend disclosed by the present invention effectively prevents Echinacea-derived alkamides or isobutylamides from oxidation and degradation, thereby enhancing their abilities to activate CB1 and shell-life. The vitamin C is preferably in the form of ascorbic acid rather than esters, salts or chelates. The vitamin E is preferably in the form of free tocopherols, and more ideally in the form of mixed tocopherols. In yet another embodiment of the present invention, it is preferred that the lecithin, vitamin C and vitamin E in the ternary blend have a ratio of 2:1:1 to 10:1:1 (lecithin:ascorbic acid:tocopherols); ideally, 4:1:1 to 5:1:1. When they are administered with Echinacea-derived isobutylamides or alkamides, it is preferred that their concentration is between 2,000 to 10,000 ppm, ideally 3,000 to 3,500 ppm. For example, an ideal concentration can be 2500 ppm:500 ppm:500 ppm (for lecithin, ascorbic acid and tocopherols) for a 3,500 ppm ternary blend.
In yet another embodiment of the present invention, the method of present invention further comprises administering the mammal with vitamin D. The vitamin D is preferably selected from group consisting of ergocalciferol (D2) and cholecalciferol (D3), and ideally includes cholecalciferol (D3). The preferred dosage is between 400 to 6000 IU (International Unit) per day, and ideally at least 4000 IU per day. The advantage of having vitamin D is that, in addition to well-known effects on calcium uptake, it may up-regulate intestinal glucose transport via SGLT1, thereby improving glucose and net macronutrient uptake. Vitamin D is also capable of inhibiting uncoupling protein 2 (UCP2), which facilitates mitochondrial proton leak and contributes to RMR. By inhibiting UCP2, vitamin D can reduce thermogenesis and metabolic rate, thereby promoting caloric surplus. Vitamin D is also known to be associated with β-cell function, systemic inflammation, insulin secretion, and insulin sensitivity. Thus, improved vitamin D status may improve glucose homeostasis and disposal, especially in mammals which are diabetic or pre-diabetic. In addition, many gastrointestinal disorders are often associated with vitamin D deficiency. These disorders frequently include impaired nutrient uptake, suppression of appetite, and difficulty gaining weight. Lastly, vitamin D may play a number of roles in immunity, with effects on tight junctions, pathogen invasion, commensal bacterial colonization, antimicrobe peptide secretion, and mucosal defense. For example, vitamin D administration may prevent influenza in some populations, as well as improve the cure rate of hepatitis C treatment, an infection characterized by loss of appetite and weight loss.
In yet another embodiment of the present invention, the method of present invention further comprises administering the mammal with zinc, ideally chelated zinc selected from group consisting of zinc gluconate, zinc picolinate, zinc orotate, zinc aspartate and zinc monomethionine. It is preferred that 10 to 150 mg of elemental zinc, ideally 20 to 40 mg is administered to the mammal per day. The purpose of adding zinc is to correct and prevent zinc deficiency, which is often characterized by reduced appetite and sense of taste, while avoiding excessive zinc supplementation, characterized by nausea and gastrointestinal upset, which may further reduce appetite and impair weight gain.
The nutritional supplement disclosed by the present invention also contains a number of different alkamide or isobutylamide compounds derived from different Echinacea species as illustrated above. These lipophilic alkamide or isobutylamide compounds are one of the primary classes of biologically active constituents in Echinacea that have been identified. The nutritional supplement can be in the form of a tablet, capsule, caplet, granule, particulate, agglomerate, spansule, chewable tablet, lozenge, or troche.
In one preferred embodiment of the present invention, the nutritional supplement comprises an antioxidant and at least two types of alkamide or isobutylamide compounds extracted or otherwise derived from Echinacea species selected from group consisting of Echinacea angustifolia, Echinacea atrorubens, Echinacea laevigata, Echinacea pallida, Echinacea paradoxa, Echinacea purpurea, Echinacea sanguinea, Echinacea simulate and Echinacea tennesseensis. Minerals such as zinc or magnesium can optionally be add to the nutritional supplement of the present invention to provide even better effect.
In one preferred embodiment of the present invention, the nutritional supplement is in solid dosage form and comprises Dodeca-2E,4E,8Z,10E/Z-tetraenoic acid isobutylamides extracted or otherwise derived from Echinacea purpurea and Dodeca-2E,4E-dienoic acid isobutylamide extracted or otherwise derived from angustifolia. While the ratio between these two is not critical, it is preferred that higher proportion of Echinacea extracts from Echinacea angustifolia is used when combining with Echinacea extracts derived from Echinacea purpurea. For example, the preferred proportion between Echinacea angustifolia and Echinacea purpurea is 6:4 to 8:2.
In another embodiment of the present invention, the nutritional supplement additionally includes other Echinacea alkamides selected from group consisting of Dodeca-2E,4Z-diene-8,10-diynoic acid isobutylamide; Undeca-2Z,4E-diene-8,10-diynoic acid isobutylamide; Undeca-2-ene-8,10-diynoic acid isobutylamide; Dodeca-2E-ene-8,10-diynoic acid 2-methylbutylamide; Dodeca-2E,4E,8Z-trienoic acid isobutylamide; Pentadeca-2E,9Z-diene-12,14-diynoic acid isobutylamide; and Dodeca-2E,4Z-diene-8,10-diynoic acid isobutylamide, or any combination thereof.
The antioxidant used is selected from group consisting of alpha tocopherol (vitamin E), butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), ascorbyl palmitate, propyl gallate, dodecyl gallate, ethyl gallate, octyl gallate, lecithin, vitamin C, vitamin E or any combination thereof. Minerals such as magnesium and zinc can optionally be added to the nutritional supplement of the present invention.
In yet another preferred embodiment of the present invention, the Dodeca-2E,4E,8Z,10E/Z-tetraenoic acid isobutylamides has a minimal concentration of 0.03% by weight, on the dried basis, with ideal concentration between 0.05% to 0.20%. The Dodeca-2E,4E-dienoic acid isobutylamide has minimal concentration of 0.01% by weight, on the dried basis, with ideal concentration between 0.01% and 0.03%.
In yet another preferred embodiment of the present invention, when the Echinacea total alkamide concentration is less than 0.10% by weight, on the dried basis, it is recommended that the dosage of the Echinacea (as powder on a dry basis) is between 1600 to 3600 mg per day, ideally at 2400 mg per day. When Echinacea with a higher concentration is used, it is recommended that the dosage of the Echinacea (as powder on a dry basis) is between 400 to 1600 mg per day, ideally 800 to 1200 mg per day. It is also recommended that the nutritional supplement is taken daily with two to four dosages.
FIGS. 1 and 2 illustrate ideal formulations for the nutritional supplement of the present invention in capsules. Note that the present invention does not limit itself to the two examples illustrated below. Rather, these two examples merely demonstrate how the nutritional supplement can be formulated in accordance with the present invention. All the Echinacea extracts used in these two examples can be replaced with different type of Echinacea extracts disclosed in the present invention or commonly known to one skilled in the art. In addition, vitamins and minerals can also be replaced with ones that provide similar characteristics.
FIG. 3 is data collected from approximately 1200 test subjects showing their weight gain after taking formulation containing only Echinacea extracts. Table 2 is data collected from another 1200 test subjects showing their weight gain after taking formulation with Echinacea extracts, Vitamin D3, Zinc and Ternary Blend (as illustrated in FIG. 2). FIGS. 5 and 6 summarized the results of FIGS. 3 and 4.
As the results show in FIGS. 5 and 6, while both formulations provide effective weight gain for the individuals, formulation with Vitamin D3, Zinc and Ternary Blend provides approximately 26.4% higher rate of weight gain than formulation with only the Echinacea preparations.
Among other things, the present invention provides various benefits and advantages to the people seeking weight gain. Specifically, the present invention increases the appetite and slows the metabolism of an individual by activating the CB1 of the individual with Echinacea extracts, thereby enhancing the weight gain of the individual. First, the present invention is capable of temporarily slowing metabolic rate to hypometabolic levels for the purpose of increasing net calorie surplus for body weight gain. Second, the present invention is capable of treating conditions arising from hyperthyroidism. Third, with the novel antioxidant created from present invention's ternary blend, the present invention also provides a method for inhibiting the degradation and breakdown of alkamides from cut or ground plant stock, whether dry or wet, and extracts from Echinacea, whether obtained from alcohol or otherwise. This method further prevents oxidation from environmental exposure, including, but not limited to, oxygen and light.
It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
