Yes! Highly recommend taking a blood test to see where your levels are at before you begin supplementing. I also think it’s worth doing for sure. Also I would be weary of taking supplements without the blood test – I took Vitamin D every day until I got a test and realized I had a toxicity in Vitamin D. This isn’t typically dangerous with Vit D but definitely can be with other vitamins.
Also, vitamins bought at CVS are not going to do much for you. The quality of the vitamins themselves are really important – if you don’t get the right stuff you might as well get nothing at all.
