I am a college student so therefore basically poor. So I was curious if anyone had any advice to the choosing the cheapest yet still most effective supplements. Specifically, I was taking a probiotic, but I’m running low and need to buy moor. Now I’m wondering if just doing grape bitters would be a good substitute for a probiotic. Since I can’t really afford both at the same time, would it be ok to alternate when I run out of one?
