Research presented at ESHRE 2025 links gut bacteria and amino acid imbalances to miscarriage risk in younger women with PCOS.

Some products, however, zero in on just the three branched-chain amino acids (BCAAs)—leucine, isoleucine, and valine—because of their potential role in muscle building and recovery.

Results showed a significant reduction in microbial diversity among PCOS patients, particularly a decrease in P. merdae, a species linked to metabolic health. Serum metabolomics revealed elevated ...

Valine “Amino acid supplements can either be individual amino acids, specific combinations, such as branched-chain amino acids (BCAAs), which include leucine, isoleucine, and valine, or a blend ...

You also might find branched-chain amino acids, a.k.a. leucine, isoleucine, and valine, which all have a similar chemical structure and are the three most important aminos for building muscle.
