I have a Vitamin D deficiency due to the fact that I'm lactose intolerant so I take D3 and fish oil pills, but I don't take a multivitamin. I should start taking vitamins more regularly.

Fish oil pills are amazing though. I have arthritis and I've seriously never felt better after taking them. I did a split yesterday.

Taking Biochemistry, I do know that there is a such thing is too much Vitamin C. I've learned that the hard way with drinking a carton of orange juice a day.
