Well actually Hemp Oil and Omega 3. I get my Hemp Oil from Holland & Barrett and my Omega 3 from Boots , and I can recommended that they both seem to work from me. Hemp is a very versatile product and the way Omega 3 works was brilliantly analogised for me by a diabetic nurse which I documented here. It is , of course , possible that effect is a placebo effect and I just think I feel better, but if something causes that then you tend to perform better and just generally be better.
Last night one of my friends Chris Ball told me a story about someone who was taking loads of vitamin supplements , which "must be working because they make my wee smell funny". Chris is responsible for the excellent but brief "Ape of Wrath" blog.
Also he mentioned that the government were going to push aspirin as a "Vitamin S" cure all , unless you are advised not to by your doctor, which then becomes a bit of an iffy policy to say the least. I personally think you should generally try and get your vitamins by eating the correct (fresh) foods (fruit and vegetables), but people will still swear by their little rattling plastic containers.
