Buffered vitamin c is non acidic. A good form to take is ester c, which is vitamin v with calcium. For carotene, you could eat carrots, other vegetables high in carotene, or take supplements. Lycopene is what makes fruits and vegetables have a red color, If you want lycopene then eat tomatoes, watermellon, red peppers, red grapefruit, etc., or take supplements. Magnesium oxide is very poorly absorbed, Taking magnesium citrate or magnesium ascorbate(magnesium with vitamic c) would be a much better choice. Some epsom salts might also have some impurities in it. While many epsom salts say USP on it and are theoretically pure enough to ingest, most are made with the intention of people soaking in it and not ingesting it. Molybdenum is safe in reasonable quantities. I take one mg(1000 mcg) a day. Taking over 3 mg a day is imo not a good idea.
