Vitamins and Supplements You Should Never Mix

Vitamins D, E and K

“Studies have shown that a person’s absorption of Vitamin K may be reduced when other fat-soluble vitamins such as Vitamin E and Vitamin D are taken together,” says Dr. Chris Airey, M.D. “It’s advised that you take these vitamins at least 2 hours apart to maximize your absorption.”Thankfully, there are no harmful side effects, however Dr. Airey says it’s “simply not efficient” to take them together as your body’s ability to absorb the vitamins will be reduced if you take them together.
