Patient discussion about retinol

Q. Can a food rich in vitamin B12 will help for his depression or vitamin B12 pills are always required? Hi all…..having one question related to my friends depression and its relation to vitamin B12, as a medicine given to him by his Doctor. Can a food rich in vitamin B12 will help for his depression or vitamin B12 pills are always required?

A. Yes low level of vitamin B12 is associated with depression. You can complete its deficiency by having good diet which will cover the B12 requirements. What happens that depressed people tend to eat less of healthy food and which reduces the B12. So, it again reduces the capacity to fight against the depression.

Q. Can someone give me some information on over intake of Vitamin A and its complications in future? I am having short sightedness. I am wearing specks for the past 3 years. Last week my eye sight had doubled. I never thought to control my eye sight by having a good diet, which is rich in vitamin A. Now I am willing to have vitamin A in tablets and I doubt the adverse effects if taken in excess. Can someone give me some information on over intake of Vitamin A and its complications in future?

A. Having tablets will fortify you with vitamin A but long term intake will lead to show the side effects of over intake. You can have these vitamin tablets as per your doctor’s prescription. But you must have them as a diet intake which will keep your vitamin intake balanced and will not lead to any complications. But the over intake of vitamins can lead to vitamin A toxicity. This can show symptoms as fatigue, muscle pain, depression, Fever and liver anemia.
