As the title says what goes with what with regard to supplements. Is there a chart anywhere that puts the information clearly.I have read but can't remember where (foggy brain) that if you take certain vitamins or other supplements you need to take so and so to balance or support it. If there isn't one perhaps we can put one together with amounts and proper names?
Particularly interested in vitamin B12 as mine is only 311( sorry no range given) which doctor says is normal.
Hope you can help please.
