IS
DEPRESSION A VITAMIN DEFICIENCY?
"In
our study, participants with a dietary
folate
intake in the lowest 'intake level] had a 67% greater risk of having
elevated depressive symptoms than those in the highest 'intake levels.] ...Low
blood levels of folate were 'also] associated with a poor response to
treatment with antidepressants. Analysis
supported the existence of an independent relationship between dietary
folate intake and current depression...'Low] dietary intake of folate has
been strongly associated with 'high] levels of
homocysteine*
in the blood. Low levels of
riboflavin
may also lead to the
accumulation of homocysteine in people who have low folate levels."
The
study was done of middle-aged men in Finland.
*Homocysteine has been
associated with heart disease. Reducing it by consuming folate would be an
added benefit.
DETAILS: Folate and
riboflavin are B vitamins and can be obtained in multiple vitamin tablets.
400mg is the recommended dose of folate (folic acid) and most combinations
contain 25mg. of riboflavin which is far more than recommended, though not
toxic. Generous servings of green leafy vegetables (except lettuce) also
provide folate.
