The present invention is directed to a method of replacing collagen broken down during physical activity using a novel dietary supplement. The supplement composition of the present invention comprises collagen, glutamine, taurine, and, optionally, the nine essential amino acids. The uptake of collagen is enhanced using this combination of components to levels substantially near the pre-workout levels.

Provided herein are compositions (e.g., pharmaceutical compositions, nutraceutical compositions, foods, beverages, cosmetic compositions, diet supplements) comprising deuterated caffeine. The provided compositions may be useful for treating and/or preventing various diseases and conditions, such as obesity, causing weight loss, increasing metabolic rate, reducing appetite, increasing energy expenditure, increasing urine output, increasing sodium excretion, reducing edema, a pain disorder, apnea, hypotension, an encephalopathy, a neurological or psychiatric disorder, and an inflammatory disorder.

The present invention provides a composition containing α-lipoic acid and N-acetylcysteine as active ingredients. The mixed composition of α-lipoic acid and N-acetylcysteine of the present invention can reduce a risk of side effects due to drugs with synergetic effects due to merge administration of two drugs, and can be usefully used for preventing or treating obesity with excellent effects of inhibiting a weight gain compared to each single composition containing α-lipoic acid or N-acetylcysteine.

Provided herein are dietary supplement compositions comprising a plurality of beadlets and an oil. Provided herein are also dietary supplement compositions comprising a plurality of mini-tabs and oil. The beadlets or mini-tabs comprise at least one nutrient that is miscible in aqueous solution, and the oil comprises at least one fat-soluble nutrient. The composition may be contained within one or more capsules, and be packaged with a scented insert.
