This is a high-quality product. I have a challenge paying attention to what works and doesn't work in my body, so giving details on a product is hard. I just know that when I take this I feel better, and when I don't take it, I notice a difference. It is also a supplement that is recommended for people with type B blood from Eat Right For Your Type, I believe is the title.
