Vitamin-C is needed for the synthesis of collagen and connective tissues. This vitamin also helps in boosting the repair mechanism of the body and of course the immune system. Vitamin-C is involved in the chemical process that involves tryptophan ( the “feel good” brain chemical of the body). It acts as a cofactor for for tryptophan-5-hydroxylase. Tryptophan-5-hydroxylase hastens the hydroxylation of tryptophan to the “feel good” brain chemical serotonin. Difficiency of Vitamin-C means an impaired production of tryptohan which may lead to depression.
In one study involving vitamain-C , 40 psychiatric patients received 1 g/day of ascorbic acid or a placebo for three weeks. In a double-blind test, The vitamin C group, yields significant improvements in depressive, manic and paranoid symptom complexes, as well as in overall functioning. ( Source: Milner G.
