Since starting training in August, after the first week I felt run down. My mate who is into TT recommended 1000mg Vitimin C a day. After a week I felt better than ever. In beginning of november I had two weeks off for the birth of my son and since then have had 3 chesty colds in 7 weeks. Can anyone tell me what supplements they are on and whether im on the right track. Am I doing my immune system any harm taking such a high dose vitimin C, should i just take a multi one instead.
