Vitamins

Every vitamins entry in the Typed supplements library. Each one is a full page: what it does, stage by stage, and what the evidence says.

• BiotinThe hair and nails vitamin — with a genuine lab test problem.
• Folate (B9)Easy to confuse with folic acid, which is the synthetic version.
• Methylfolate (5-MTHF)The already-active form of vitamin B9, the essential nutrient your body needs to make red blood cells and DNA — a real nutrient, with a more modest case for needing this exact form over regular folic acid.
• NiacinamideA form of vitamin B3 that your body genuinely needs — famous for preventing a historic deficiency disease, with a smaller, less-settled body of evidence for joint and skin benefits at much higher doses.
• Vitamin AOne of the few vitamins you can genuinely take too much of.
• Vitamin B1 (Thiamine)Essential for turning carbohydrates into usable energy.
• Vitamin B12Your stomach has to make a helper protein before you can absorb it at all.
• Vitamin B2 (Riboflavin)The one that turns your urine bright yellow when you take more than you need.
• Vitamin B3 (Niacin)One form of it causes a harmless but genuinely startling skin flush.
• Vitamin B5 (Pantothenic Acid)Its name comes from the Greek for everywhere — because it is in almost every food.
• Vitamin B6Involved in over a hundred different reactions in your body.
• Vitamin CUseful, but it will not stop you catching a cold.
• Vitamin D3Your skin makes it from sunlight — but often not enough.
• Vitamin EA real antioxidant for your cell membranes — but not the heart protector it was sold as.
• Vitamin K1 (Phylloquinone)A fat-soluble vitamin your body needs to make blood clot properly — well proven for that, less proven for the bone and heart claims often pinned on it.
• Vitamin K2Helps steer calcium into your bones instead of your artery walls.
