Unfortunately, it is almost impossible to get adequate amounts of certain vitamins from diet alone. Vitamin K2 comes to mind; about 96% of all Americans have a Vitamin K2 deficiency. Ironically, most Americans get at least adequate amounts of Vitamin K1 via diet alone. The foods that are rich in Vitamin K2 are not consumed in adequate enough amounts.The best vitamins come from a good diet.
I have been with Pure Encapsulations for years. Quality Vitamins and Supplements. Recommend daily Zinc, 5000 D3, Omega 3 and very high quality turmeric for joint pain. Taking a tablespoon of virgin olive oil everyday and apple cider vinegar would not hurt.The supplements industry, which includes vitamins, is not regulated. So there are a lot of vitamins on the market that don't provide any significant available of what's in them. I generally start with Pure Encapsulations when looking for vitamins. More expensive, but they work.
