I was on my vitamin website getting more vitamins, I wish I was more smarter to understand vitamin talk & how much to take (mg & mcg) I also wish I knew other stuff like if I can stop talking D3 or vitamin B, cuz I’m spending alot of money on vitamins. With my other vitamins, there vitamins D,C, Zinc already in them, but I don’t know how much I need, but other vitamins can do different things. One of my vitamins is B with C, it helps with being super stress, it also helps with energy & metabolism, it one of the highest prices, but I think it worth it.
