On the drug interaction issues, you could do a search with some of your drugs and supplements you may want to take.

Ones that really concern you, talk to a "smart" pharmacist.

Personally, I choose to use about ALL supplements for my health and know that some I take thin and clean the blood but better thinner blood than clotting blood. Those taking pharma blood thinners have to be aware of that. Many on blood thinners will bruise easier when they add too much Vit C and others. So I know that much.
