Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No. 16/184,806, filed Nov. 8, 2018, which is a continuation-in-part of U.S. application Ser. No. 15/997,409, filed Jun. 4, 2018, now U.S. Pat. No. 10,143,223, the content of each of which are hereby incorporated by reference in their entirety.

BACKGROUND

Sports drinks have been developed to assist with the losses of various nutritional components during physical activity. The nutritional components may include sugars, electrolytes, vitamins, minerals, amino acids, and proteins. Physical activity includes not only exercise and sports by healthy individuals, but may also include any activity where important nutrients are lost, such as work by factory or farm workers, activity by chronically ill patients, living in harsh conditions such as in the tropics or in the desert, and so forth.
Following exercise, replenishing the lost water and nutrients has been the goal of a few decades of sports drink research. Nutritional intervention to achieve maximum muscle recovery has been primarily directed toward restoration of fluid and electrolytes or the replenishment of muscle glycogen stores. Muscle recovery depends on four major factors, namely, restoration of fluid and electrolytes, replenishment of muscle glycogen, reduction of oxidative and muscle stress, and rebuilding and repair of muscle protein damaged.
Typically marketed sports drinks contain sugars and electrolytes. Some examples of the sugars contained in the sports drinks include sucrose, glucose, or fructose. Typical electrolytes include sodium salts, potassium salts, and chloride salts.

SUMMARY

The present disclosure, in one embodiment, provides sports drinks with improved ability to rehydrate individuals especially before or after intense physical activities. Further, the disclosed sports drinks can reduce muscle soreness or fatigue, improve muscle performance, and minimize muscle cramping. Such improved characteristics of the sports drinks, which are contemplated to be associated with well-balanced magnesium content and magnesium/potassium ratio, surprisingly can be formulated with desirable flavor for people.
In one embodiment, therefore, the present disclosure provides a drinkable aqueous solution comprising, per 16 fluid ounces (473 mL) of the solution: 50 to 400 mg Mg²⁺; 100 to 300 mg Na⁺; 100 to 200 mg K⁺; 2-10 grams sugar; 50 to 200 mg stevia extract; 2-10 mg monk fruit extract; and at least 450 mL water, wherein the solution has an osmolarity below 250 mosmoles per liter (mOsm/L), the ratio of Mg²⁺to K⁺ is from 1:3 to 2:1, and the ratio of stevia extract to monk fruit extract is from 50:1 to 5:1. In some embodiments, the osmolarity is below 220 mOsm/L. In some embodiments, the osmolarity is from 50 to 200 mOsm/L.
In some embodiments, the ratio of Mg²⁺to K⁺ is from 1:2 to 1:1. In some embodiments, the ratio of stevia extract to monk fruit extract is from 25:1 to 10:1. In some embodiments, the solution comprises 50-200 mg of the Mg²⁺per 16 fluid ounces of the solution.
In some embodiments, the solution comprises, per 16 fluid ounces of the solution: 70 to 150 mg Mg²⁺; 150 to 250 mg Na⁺; 125 to 175 mg K⁺; 4-6 grams sugar; 80 to 120 mg stevia extract; and 4-6 mg monk fruit extract. In some embodiments, the solution comprises, per 16 fluid ounces of the solution: about 100 mg Mg²⁺; about 200 mg Na⁺; about 150 mg K⁺; about 5 grams sugar; about 100 mg stevia extract; and about 5 mg monk fruit extract.
In some embodiments, the solution further comprises vitamin C, citric acid, and a flavoring agent. In some embodiments, the solution comprises the ingredients as shown in Table 1, 2, or 3.

In some embodiments, the administration follows an intense physical activity by the subject. In some embodiments, the subject experiences muscle soreness, fatigue, or cramping. In some embodiments, the administration is prior to the subject undertaking an intense physical activity.
Compositions are also provided that, when dissolved in water, can prepare a drink of the present disclosure.

DETAILED DESCRIPTION

The following description sets forth exemplary embodiments of the present technology. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure but is instead provided as a description of exemplary embodiments.
The instant inventor has made the unexpected discovery that suitable concentrations of magnesium, sodium and potassium ions in a sports drink, in particular a relatively high concentration of magnesium and a balanced magnesium to potassium ratio, when used by an individual engaged in intense physical activities, help reduce muscle soreness and fatigue, improve muscle performance, and minimize muscle cramping. A suitable concentration of magnesium may be 50 to 400 mg Mg²⁺ per 16 fluid ounces (473 mL) of the drink (about 0.1 mg/mL to about 0.85 mg/mL). A suitable ratio of magnesium to potassium may be 1:3 to 2:1 (w/w).
In addition, it is contemplated that the sports drink contains relatively low sugar content to reduce osmolarity. In some embodiments, the preferred osmolarity is below 250 mosmoles per liter (mOsm/L), or below 200 mOsm/L. Magnesium drinks (e.g., magnesium citrate) are known to pull fluid from the body. Therefore, the lower osmolarity than in common products on the market helps to improve rehydration.
A common problem associated with drinks with high content of magnesium is their sour taste. Efforts have been made to neutralize this taste, and it is herein discovered that a combination of stevia extract and monk fruit extract, at the right ratio (e.g., 50:1 to 5:1, w/w), can help remove the disfavored taste.
In accordance with one embodiment of the present disclosure, therefore, provided is a drinkable aqueous solution comprising, per 16 fluid ounces (473 mL) of the solution, 50 to 400 mg Mg²⁺; 100 to 300 mg Na⁺; 100 to 200 mg K⁺; 2-10 grams sugar; 50 to 200 mg stevia extract; 2-10 mg monk fruit extract; and at least 450 mL water. Preferably, the solution has an osmolarity below 250 mosmoles per liter (mOsm/L). In some embodiments, the ratio of Mg²⁺to K⁺ is from 1:3 to 2:1 (w/w). In some embodiments, the ratio of stevia extract to monk fruit extract is from 50:1 to 5:1 (w/w).
The osmolarity of the solution is preferably lower than 250 mOsm/L. In some embodiments, the osmolarity is below 240 mOsm/L, 230 mOsm/L, 220 mOsm/L, 210 mOsm/L, 200 mOsm/L, 190 mOsm/L, 180 mOsm/L, 170 mOsm/L, 160 mOsm/L, 150 mOsm/L, 140 mOsm/L, 130 mOsm/L, 120 mOsm/L, 110 mOsm/L, 100 mOsm/L, 90 mOsm/L, 80 mOsm/L, 70 mOsm/L, 60 mOsm/L, 50 mOsm/L, 40 mOsm/L, 30 mOsm/L, 20 mOsm/L, 15 mOsm/L, 10 mOsm/L, 9 mOsm/L, 8 mOsm/L, 7 mOsm/L, 6 mOsm/L, 5 mOsm/L, 4 mOsm/L, 3 mOsm/L, 2 mOsm/L, or 1 mOsm/L.
In some embodiments, the osmolarity is higher than 1 mOsm/L, 2 mOsm/L, 5 mOsm/L, 10 mOsm/L, 15 mOsm/L, 20 mOsm/L, 30 mOsm/L, 40 mOsm/L, 50 mOsm/L, 70 mOsm/L, 80 mOsm/L, 90 mOsm/L, or 100 mOsm/L.
The ratio of Mg²⁺ to K⁺ is preferably from 1:3 to 2:1, or from 1:2 to 2:1, from 2:3 to 1:1, from 1:3 to 3:2, or from 1:3 to 1:1 (w/w). In some embodiments, the ratio of Mg²⁺ to K⁺ is about 1:1, 1:2, 2:3 or 3:4 (w/w).
The ratio of stevia extract to monk fruit extract is preferably from 50:1 to 5:1, or alternatively from 45:1 to 5:1, 40:1 to 5:1, 35:1 to 5:1, 30:1 to 25:1, 20:1 to 5:1, 45:1 to 6:1, 45:1 to 7:1, 45:1 to 8:1, 45:1 to 9:1, 45:1 to 10:1, 45:1 to 11:1, 45:1 to 12:1, 45:1 to 13:1, 45:1 to 14:1, 45:1 to 15:1, 45:1 to 16:1, 45:1 to 17:1, 45:1 to 18:1, 45:1 to 19:1, 45:1 to 20:1, 40:1 to 6:1, 40:1 to 7:1, 40:1 to 8:1, 40:1 to 9:1, 40:1 to 10:1, 40:1 to 11:1, 40:1 to 12:1, 40:1 to 13:1, 40:1 to 14:1, 40:1 to 15:1, 40:1 to 16:1, 40:1 to 17:1, 40:1 to 18:1, 40:1 to 19:1, 40:1 to 20:1, 30:1 to 6:1, 30:1 to 7:1, 30:1 to 8:1, 30:1 to 9:1, 30:1 to 10:1, 30:1 to 11:1, 30:1 to 12:1, 30:1 to 13:1, 30:1 to 14:1, 30:1 to 15:1, 30:1 to 16:1, 30:1 to 17:1, 30:1 to 18:1, 30:1 to 19:1, 30:1 to 20:1, 25:1 to 6:1, 25:1 to 7:1, 25:1 to 8:1, 25:1 to 9:1, 25:1 to 10:1, 25:1 to 11:1, 25:1 to 12:1, 25:1 to 13:1, 25:1 to 14:1, 25:1 to 15:1, 25:1 to 16:1, 25:1 to 17:1, 25:1 to 18:1, 25:1 to 19:1, or 25:1 to 20:1.
Stevia is a sweetener and sugar substitute extracted from the leaves of the plant species Stevia rebaudiana. The active compounds of stevia include steviol glycosides (mainly stevioside and rebaudioside). Stevia's taste has a slower onset and longer duration than that of sugar, and some of its extracts may have a bitter or licorice-like aftertaste at high concentrations.
Stevia extracts and derivatives are produced industrially and available commercially. Example include Rebiana, which is an abbreviated name rebaudioside A, and Truvia and PureVia which are an Erythritol, Rebiana.
Monk fruit (Siraitia grosvenorii) is a herbaceous perennial vine of the Cucurbitaceae (gourd) family, native to southern China and northern Thailand. The plant is cultivated for its fruit, whose extract is nearly 300 times sweeter than sugar and has been used in China as a low-calorie sweetener for cooling drinks and in traditional Chinese medicine.

Ingredients of Test Sample

	Ingredients	Amount

Magnesium	100	mg
Sodium	200	mg
Potassium	150	mg
Sugars	5	g
Water	q. v. 473	mL

The test samples were provided to six mixed martial artists. Each of them drank about 2 bottles each (16 fl. oz/bottle) during a 45 minute strenuous endurance work out. The unanimous opinion of all of these individuals was that the drink significantly improved their performance during their workouts, and reduced post-exercise muscle soreness and fatigue. All of these individuals had several comments on social media about how the drink can help athletes rehydrate better.
During the same period, two additional adults and a 8-year boy took the test samples to Zion national park in Utah. They used it to hydrate themselves on a 5-mile hike in the canyons in 92 degree heat. All three of them felt marked difference in their muscle performance and felt relatively energetic despite the long hike. Specifically, they did not feel exhausted despite a relatively long climb in the middle of a hot day. There was minimal muscle soreness or cramps afterwards. They attributed this to the proper formulation of electrolytes they used to hydrate themselves.
A fitness and training coach, who ran the marathon, reported that he ran his personal best the day he used the drink and felt the drink specifically improved his performance.
A number of professional basketball (NBA) players tried the drink pre and post workout. Their overall impression was the same as above: less muscle soreness or fatigue, improved muscle performance, minimal cramping.

Example 2

Production samples were prepared with two different flavors, a lemon flavor and an orange flavor. The samples included different amounts of flavor agents, stevia extract and monk fruit extract. It was discovered that, when the amounts of stevia extract and monk fruit extract were 100 mg and 5 mg, respectively (in 16 fluid ounces formulations), the samples had the least “magnesium taste” and were most enjoyable.
