Stable creatine beverages

Example 1: Preparation of Ready-to-Drink Beverages

[0139]The following two ready-to-drink beverage formulations were prepared by mixing all ingredients until they dissolved completely. The beverage was then mixed for a further 15 minutes. The beverage was then heat treated at 195+ / −2° F. for 21-23 seconds, filled at 180° F. to 185° F. and cooled rapidly to room temperature.

Example 2: Stability Study of Ready-to-Drink Beverages

[0142]The stability of the two ready-to-drink beverages described Example 1 was studied. The beverages were allowed to stand at 5° C. or 21° C. for the period of time indicated. Creatine was measured by HPLC with UV detection according to the method provided in Analytical Biochemistry 2014, pp. 278-283 (1993). Briefly, reversed-phase chromatography on a C18 column by employing gradient elution and UV detection at 210 nm was utilized. Separation was achieved in less than 5 minutes. The results are provided in Tables 1 and 2, below:
