Biotin, a feel-good vitamin?
Maybe, just maybe, a high intake of biotin boosts overall mental health. If so, then researchers from Iran have discovered this association. But Baharak Mahdavifar and his colleagues are not going to bet their money on it.
Biotin is involved in breaking up fats, carbohydrates and proteins. The higher your metabolism and the more intensively you exercise, the higher your need for biotin.
Because fragile nails and brittle hair are a symptom of a biotin deficiency, you can often find the vitamin in supplements and functional foods that should help keep nails and hair healthy.
Mahdavifar knew the study participants' diets and was able to calculate their intake of B vitamins. The study participants also had questions answered about their mental health. Mahdavifar then looked at whether he could find an associations between dietary intake of B vitamins on the one hand and mental health on the other.
Vitamin B6 also reduced the risk of stress.
The researchers split their data separately for men and women. Back then, both men and women with high intakes of biotin were still less likely to experience stress symptoms, anxiety and depression than men and women with lower intakes, but the difference was only statistically significant in women.
"The relationship between dietary biotin and depression, anxiety, and stress could be explained by other beneficial components of a biotin-rich diet, writes Mahdavifar.
"The role of B vitamins requires further investigation in randomized controlled trials."
