Branched-Chain Amino Acids (BCAAs) refer to a group of three essential amino acids: leucine, isoleucine, and valine. These amino acids play key roles in muscle protein synthesis, energy production, and recovery, especially during physical activity. Measuring total BCAA levels in the blood provides insight into protein metabolism, nutritional status, and muscle health. Imbalances can be linked to poor dietary intake, metabolic dysfunction, or increased demand due to stress, illness, or intense training. BCAA levels are particularly relevant for athletes, individuals with fatigue, or those recovering from illness or muscle loss.

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the UK. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

Absolutely perfect, results came after few days and finally after a lots of times visited GP, we finally know why my son has eczema - he is allergy to carrot. Thanks a lot.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.
