Feeling Stressed and Struggling With Sleep? B Vitamins Might Help.

A 2025 randomized, double-blind, placebo-controlled trial published in Nutrients found that supplementing with 100 mg each of vitamin B1 (thiamine) and B2 (riboflavin) daily for four weeks significantly reduced perceived stress and improved sleep quality in young adults. Participants in the supplement group experienced a notable decrease in stress scores and reported better sleep quality and reduced daytime sleepiness compared to the placebo group. 

However, the study did not find a significant effect on anxiety levels, suggesting that while B1 and B2 supplementation may alleviate stress and enhance sleep, they might not directly impact anxiety symptoms. These findings highlight the potential of targeted B vitamin supplementation as a natural approach to managing stress and improving sleep quality.

Consider incorporating vitamin B1 and B2 supplements into your routine to support stress reduction and better sleep.
