I found a pretty cheap zinc spplement with the main ingredient being zinc gluconate. Is it useful (it contains 5mg Zinc/capsule. EDIT: I can take a few capsules at once…and am not exactly what you would call trained…)? (easily assimilated) It also vitamin B5 and vitamin C.
Another question is if oats are a good source of minerals. On the label, it says they contain a ton of minerals (magnesium, zinc, phosporus, iron), but I remember once reading that there is an assimilation problem with the minerals in some vegetables…also the fact that oats contain a lot of fibre also makes me wonder wether the minerals are absorbed…
Or walnuts (150mg magnesium/100g)?
Many thanks, Vlad
