The Very Best Vitamins To Take According to Dietitians

For this post, I interviewed dietitians about the best vitamins to take. Not surprisingly, you may be missing out on vitamins and nutrients.

Getting advice about good supplements from experts in nutrition is the best way to get sound advice about vitamins.  Who has the most training in nutrients? Registered Dietitian Nutritionists.

Online dietitian experts talk here about their favorite vitamins for health, how much you need, and why these nutrients are important for your best health.

The Best Vitamins to Take: Vitamin C

The Best Vitamins to Take: Iron

Iron is a key nutrient to keep us focused and energized.  Jeanette Kimszal RDN writes about iron, how to look for deficiency, and where to get the best iron.

Iron deficiency is especially common in women of childbearing age and young children.  Too little iron can even cause muscle aches and pains!


Iodine deficiency is really common. Iodine is a nutrient you are going to want to make sure you get enough of after reading another blog from Doug Cook, RDN.

This critical nutrient affects how your thyroid works, protects breast tissue from the damages of toxins, and more.


You can get a flu shot, but have you been paying attention to your nutrition for sickness prevention?  Many nutrients play a role in your ability to fight off infections, and zinc is one you don’t want to be without all year long.

Doug Cook, RDN writes about zinc, aging, and your immune system on his blog.

Finding good vitamin brands can be exceptionally challenging, especially if you want ones that work.  Amy Gorin RDN writes about some really great supplement brands on her website.
