Abstract

Methods and compositions are provided for increasing the anaerobic working capacity of muscle and other tissues. Also provided are compositions formulated for the sustained release of free beta-alanine. Also provided is a dietary supplement formulated, for example, as a solid food product, an edible suspension, liquid or semi-liquid as described herein.

Claims (44)

1. A human dietary supplement comprising free beta-alanine or a salt of free beta-alanine,

wherein the free beta-alanine or the salt of free beta-alanine is formulated in a matrix for sustained release,

wherein a concentration of beta-alanine in a human's blood does not exceed 200 Σmol/l within 15 minutes after ingestion of the human dietary supplement;

wherein the matrix contains from about 0.1 g to about 10.0 g of the free beta-alanine or the salt of free beta-alanine per serving of the human dietary supplement, and

wherein the human dietary supplement decreases effects of paraesthesia.

2. The human dietary supplement of claim 1 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 1.0 g to about 10 g.

3. The human dietary supplement of claim 1 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 1.0 g to about 9.0 g.

4. The human dietary supplement of claim 1 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 2.0 g to about 8.0 g.

5. The human dietary supplement of claim 1 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 3.0 g to about 7.0 g.

6. The human dietary supplement of claim 1 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 4.0 g to about 6.0 g.

7. The human dietary supplement of claim 1 , wherein the sustained release formulation is in a solid, liquid or semi-liquid.

8. A human dietary supplement comprising free beta-alanine or a salt of free beta-alanine,

wherein the free beta-alanine or the salt of free beta-alanine is formulated in a matrix for sustained release,

wherein a concentration of beta-alanine in a human's blood does not exceed 375 μmol/l within 30 minutes after ingestion of the human dietary supplement;

wherein the matrix contains from about 0.1 g to about 10.0 g of the free beta-alanine or the salt of free beta-alanine per serving of the human dietary supplement, and

wherein the human dietary supplement decreases effects of paraesthesia.

9. The human dietary supplement of claim 8 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 1.0 g to about 10 g.

10. The human dietary supplement of claim 8 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 1.0 g to about 9.0 g.

11. The human dietary supplement of claim 8 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 2.0 g to about 8.0 g.

12. The human dietary supplement of claim 8 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 3.0 g to about 7.0 g.

13. The human dietary supplement of claim 8 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 4.0 g to about 6.0 g.

14. The human dietary supplement of claim 8 , wherein the sustained release formulation is in a solid, liquid or semi-liquid.

15. A human dietary supplement comprising free beta-alanine or a salt of free beta-alanine,

wherein the free beta-alanine or the salt of free beta-alanine is formulated in a matrix for sustained release,

wherein a concentration of beta-alanine in a human's blood does not exceed 300 μmol/l within 45 minutes after ingestion of the human dietary supplement;

wherein the matrix contains from about 0.1 g to about 10.0 g of the free beta-alanine or the salt of free beta-alanine per serving of the human dietary supplement, and

wherein the human dietary supplement decreases effects of paraesthesia.

16. The human dietary supplement of claim 15 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 1.0 g to about 10 g.

17. The human dietary supplement of claim 15 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 1.0 g to about 9.0 g.

18. The human dietary supplement of claim 15 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 2.0 g to about 8.0 g.

19. The human dietary supplement of claim 15 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 3.0 g to about 7.0 g.

20. The human dietary supplement of claim 15 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 4.0 g to about 6.0 g.

21. The human dietary supplement of claim 15 , wherein the sustained release formulation is in a solid, liquid or semi-liquid.

22. A human dietary supplement comprising free beta-alanine or a salt of free beta-alanine,

wherein the free beta-alanine or the salt of free beta-alanine is formulated in a matrix for sustained release,

wherein a concentration of beta-alanine in a human's blood does not exceed 100 μmol/l within 75 minutes after ingestion of the human dietary supplement;

wherein the matrix contains from about 0.1 g to about 10.0 g of the free beta-alanine or the salt of free beta-alanine per serving of the human dietary supplement, and

wherein the human dietary supplement decreases effects of paraesthesia.

23. The human dietary supplement of claim 22 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 1.0 g to about 10 g.

24. The human dietary supplement of claim 22 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 1.0 g to about 9.0 g.

25. The human dietary supplement of claim 22 , wherein the free beta-alanine, or salt thereof, in the sustained release formulation is provided in an amount ranging from about 2.0 g to about 8.0 g.
