Clinical Trial Summary

The purpose of this study is to To study the blood bioavailability of a sustained-release β-alanine granulated supplement of two different doses (10 g and 20 g).

Description:

Subjects will consume 10 g of β-alanine one day by 4 ingestions of 2.5 g separated by 1 hour and 15 min. While on another day 20 g of β-alanine by 4 ingestions of 5 g separated by 1 hour and 15 minutes, with a washout period of 15 days between the two doses. Subsequently, the amino acid levels in blood will be analyzed after the product intake and during a period of 8 hours.

Each day of visit the paresthesias (moment of appearance, intensity and sensations) will be studied at different times.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Aminoacids in plasma	The complete series of amino acids will be analyzed in plasma, after supplement intake, for 8 hours and at various times after product intakes. A bioavailability curve will be developed for each of these samples.	After the first intake of the product, samples will be taken at 15, 30, 45, 60 and 75 minutes. After the fourth and last product intake, samples will be taken at 15, 30, 45, 60, 75, 90, 120, 180 and 240 minutes.
Secondary	Paresthesia	It will be recorded by means of a visual analog scale (VAS), drawn with a continuous line of 10 centimeters where the left edge determines "no unusual sensation", translated to 0 in the recording of the data; and on the right edge "more intense sensation", translated to 10.	After the first intake of the product, samples will be taken at 15, 30, 45, 60 and 75 minutes. After the fourth and last product intake, samples will be taken at 15, 30, 45, 60, 75, 90, 120, 180 and 240 minutes.
Secondary	symptomatology - qualitative question	They should answer if they have felt at any time after the ingestion of ß-alanine any symptomatology such as: prickling, itching, tingling, numbness, chills and pain.	After the first intake of the product, samples will be taken at 15, 30, 45, 60 and 75 minutes. After the fourth and last product intake, samples will be taken at 15, 30, 45, 60, 75, 90, 120, 180 and 240 minutes.
