It seems like there are a lot of vitamins that work well together, and some don't work well if you don't have another vitamin.
Which vitamins/supplements work together, and which ones can I take separate from each other?
Is there a general rule with most vitamins? Otherwise, people are always guessing and taking a certain dosage without knowing if they actually need less or more.
Henceforth, that's why I'm always looking at different threads on here to see how much of a certain vitamin I need, but it tends to get a little confusing and overwhelming at times.
