Omega-3 fatty acids have some scientific support for their use in alleviating vaginal dryness, though the evidence is still emerging and not robust. Omega-3s, primarily found in fish oil and some plant sources like flaxseed, are well-known for their anti-inflammatory properties and roles in maintaining cell membrane integrity. Given that vaginal dryness is often related to decreased estrogen levels, particularly during menopause, and can involve inflammation and changes in mucosal tissue, researchers have considered whether improving the lipid composition of tissues and reducing inflammation via omega-3 supplementation could be beneficial.

A few small clinical studies and observational reports suggest that omega-3 supplementation may improve symptoms of vaginal dryness. For example, a 2014 randomized controlled trial published in Menopause found that women taking omega-3 supplements reported modest improvements in vaginal dryness compared to placebo. Other research has shown that diets high in omega-3s are correlated with better mucosal health in general, though these findings are not specific to the vagina.

However, the overall quality of evidence is limited. There are few large, well-controlled clinical trials, and existing studies often have methodological limitations such as small sample sizes or lack of standardized outcome measures. Most expert guidelines still recommend established therapies (e.g., vaginal moisturizers or local estrogen) as first-line treatments. Omega-3s may be considered as adjuncts but are not yet a primary or stand-alone treatment for vaginal dryness.
