Vitamins and other supplements
for quite a few years now I've been taking a multivitamin daily as well as omega 3 or cod liver oil and more recently glucosamine.
I am doing the 5:2 diet (intermittent fasting) combined with 16:8 and on my non fast days and for non fast meals I am eating mostly non processed foods with some meat and veg and no more than 100g cabs per day. I also have a small quantity of fruit like half a banana or 3-4 strawberries in a protein shake most days and fats like peanut butter, olive oil, low fat dairy (cottage cheese, Greek yogurt) or natural fats as well as the odd processed treat like ice cream or chocolate once or twice a week in fairly small quantities. In fast days I eat 550 calories with carbs at around 50-60g and protein at about 40g.
My question is that I have read several articles recently saying that most people in the developed world don't need to take vitamins except one or two which may be lacking but I'm now confused about what I need to take and what could be doing me harm if I take it. For example I don't think I need vitamin D vp because I live in a hot climate most of the time but I've read a lot about people lacking magnesium or taking omega 3 or vitamin b12 etc.
Should I ditch the multivitamin and if so is there anything I should be taking?
