I think that you should do your research on all these things for yourself, because every person has differing opinions on what to take and who knows, each and every one of us might have a wrong opinion on something that we're suggesting. For example, on another forum, I spent time discussing B12 with a guy who has been a vegan for a few years. While I'm all for taking a supplement of methylcobalamin B12 (one or two under the tongue), he was adamant that if you start out with a healthy 'load' of the intestinal bacteria that produce B12, then you never need to supplement. Maybe I'll go and visit him in the dementia ward when the time comes, eh? Anyway, if you were to listen to him, you'd have the seat next to him. While it's nice to get opinions, it's better if you do the real research yourself.
