Abstract

The present invention provides for compositions, methods and kits for regulating energy metabolism. In one aspect, the invention provides for compositions that comprise a combination of (a) branched chain amino acids, such as leucine, and (b) vitamin B6, or any precursors or metabolites of (a) or (b). These combinations may be synergistic and/or effective for reducing weight or adipose volume. In another aspect, the invention provides for methods of regulating energy metabolism by the administration of one or more compositions comprising branched chain amino acids and vitamin B6. The invention also provides for kits comprising compositions of branched chain amino acids and vitamin B6 packaged in an oral dose form with usage instructions.

Claims

1. A composition comprising:

(a) at least 250 mg of leucine and/or a leucine metabolite; and

(b) at least about 0.1 mg of vitamin B6;

wherein the leucine metabolite is selected from the group consisting of keto-isocaproic acid(KIC), alpha-hydroxy-isocaproic acid, and hydroxymethylbutyrate (HMB),

wherein the mass ratio of component (a) to (b) in said composition is greater than 65,

wherein the composition is free of the individual amino acids arginine, isoleucine and valine, and

wherein the composition comprises less than 1% of the individual amino acids alanine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, histidine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, and tyrosine.

2. The composition of claim 1, wherein component (a) is present in an amount of at least 1130 mg, and component (b) is present in an amount of at least 12 mg.

3. The composition of claim 1, wherein the composition comprises at least 500 mg of leucine and at least 5 mg of vitamin B6.

4. The composition of claim 1, wherein the composition is formulated as an oral dosage form.

5. The composition of claim 1, wherein the composition is a dietary supplement packaged as a solid food or a semi-solid food.

6. The composition of claim 5, wherein the composition is formulated as a tablet, capsule, or gel capsule.

7. The composition of claim 1, wherein the composition further comprises a food carrier.

8. The composition of claim 1, wherein the composition further comprises one or more of a sweetener, a bulking agent, a stabilizer, an acidulant, and a preservative.

9. The composition of claim 1, wherein the composition has a shelf-life greater than 7months.

10. The composition of claim 1, wherein the composition further comprises a pharmaceutically active agent or an anti-diabetic agent.

11. The composition of claim 1, wherein the composition further comprises metformin.

12. The composition of claim 1, wherein the mass ratio of component (a) to (b) in the composition is less than 100.

13. The composition of claim 1, wherein the composition is packaged as a liquid composition.

14. The composition of claim 13, wherein the composition comprises at least about 250 mg of the leucine or leucine metabolite per 16 ounces of the liquid composition.

15. A method for increasing energy metabolism in a subject in need thereof comprising administering a composition of claim 1 to the subject to effect an increase in the subject'"'"'s energy metabolism.

16. A method for enhancing fat oxidation in a subject in need thereof comprising administering the composition of claim 1 at least two times per day to effect an increase in the subject'"'"'s fat oxidation.
