How it all Works
about SR CarnoSyn®

Beta-alanine and Carnosine

The amino acids beta-alanine and histidine are the building blocks of carnosine, a powerful antioxidant naturally produced in the body. Carnosine is highly concentrated in muscle and brain tissue, and is essential for both everyday wellness and healthy aging.*

As we age, the carnosine levels in our bodies decrease. Since beta-alanine is the rate-limiting factor in carnosine synthesis, we need more as we get older. Unfortunately, it’s very hard to get the required amount of beta-alanine through diet alone.

Why not supplement with carnosine itself?

Supplementing with beta-alanine is much better for several reasons:

Cost of supplements


Due to the high unit price of carnosine, supplements can be up to 25x more expensive than beta-alanine.
Carnosyn digestion statistic


During digestion the body naturally breaks carnosine down into beta-alanine and histidine. It then has to resynthesize it back into carnosine.
40% beta alanine statistic


Carnosine supplements are typically only 40% beta-alanine by weight. The rest is unneeded histidine and added ingredients.

Molecular weight statistic


Carnosine’s molecular weight is 2.5x higher than beta-alanine.

What makes SR CarnoSyn® so effective?

SR CarnoSyn® is a sustained release form of beta-alanine so it stays in the body longer.
This enables the synthesis of more carnosine for greater bioavailability within the muscles, brain and other organs.*

The dosing has also been perfected. Studies show that 2.4 grams of beta-alanine per day is ideal to support everyday wellness and healthy aging.* Higher doses may occasionally lead to paresthesia, a harmless tingling sensation. Rest assured, SR CarnoSyn®’s patented formula has been proven safe, effective and consumer-friendly.
