Valine

From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history

Valine or L-valine is one of the nine essential amino acids for humans,[1] and is also available in branched chain amino acid (BCAA) supplements.[2]

Evidence[edit | edit source]

ME/CFS[edit | edit source]

The genes TRPV1 and VARS2 and their associated proteins influence the effects of valine in the body, and have been implicated in pathophysiology of ME/CFS. The pilot study from the ongoing ME/CFS Gene Study found that VARS2 was one of the ten relatively common genes or gene variants that were significantly more common in people with ME/CFS.[3] Iacob et al. (2016) found differences in gene expression for TRPV1 after moderate exercise in ME/CFS and fibromyalgia patients, transient vanilloid receptor (TRPV1) is associated with pain, fatigue and inflammation, including both increased fatigue and pain during post-exertional malaise in ME/CFS.[4]

Costs and availability[edit | edit source]

Available over the counter, but more often sold as a BCAA supplement.

Branched Chain Amino Acids[edit | edit source]

Valine, along with leucine and isoleucine is branched chain amino acid (BCAA).[2]

AXA1125[edit | edit source]

Valine is one of a number of amino acids in AXA1125, which is undergoing clinical trials for a number of uses.[citation needed]
