How Vitamin A and Vitamin D Levels Affect Teeth

The Miracle of Vitamin D

Phosphorus, calcium and our hormones all have something in common. They need fat-soluble vitamin D. Fat-soluble vitamin D is considered a hormone rather than a vitamin. Strange as it may sound, our bodies have developed a biological need for hormones. Fat-soluble vitamin D is essential to balance the ratio of calcium and phosphorous in our blood to stop tooth decay.

Professor and physician Edward Mellanby of England is the famous researcher who discovered vitamin D. He and his wife May Mellanby did extensive research on tooth decay which included decades of feeding experiments on animals and humans. He wrote:

By far the most important factor producing well calcified bones and teeth is vitamin D.

We need fat-soluble vitamins A and D for our cells to produce osteocalcin—the protein responsible for deposition of calcium and phosphorous into our bones. Dr. Price found that modern people suffered from tooth decay because modern diets are severely lacking in fat-soluble vitamins. To cure cavities many people simply need to add these vitamins back into their diets.

A review of this vitamin D chart shows a few important points. Seafood is an excellent source of vitamin D. For those who do not have good access to seafood, lard seems to be the densest source of vitamin D. However in feeding trials, bacon fat did not produce the same anti-cavity effect as did suet (beef fat from bovine adipose deposits). Fermented cod liver oil is the most potent source of full spectrum fat-soluble vitamin D. For vegetarians, consuming moderate amounts of butter and chicken eggs will be unlikely to provide adequate fat-soluble vita­min D. However adding Green PasturesTM butter oil, and free ranging duck eggs would more than likely ensure for plenty of vitamin D.

Supplements vs. Food

There are many studies warning of adverse health effects of too much fat-soluble vitamins A and D in the diet. Most of these studies are the result of studying vitamins A and D independently and from synthetic supplements, not whole foods. I recommend only food-based forms of these vitamins to be sure the body can metabolize them properly.

Vital Fat-Soluble Vitamin A

Water-soluble nutrients called carotenes are not true vitamin A. Carotenes are found in foods like carrots, squash, and green vegetables. Fat-soluble vitamin A is retinol and is only found in animal fats. When we are healthy our bodies can make the difficult conversion of carotenes into retinol. Depending on the fat-soluble vitamin A status in your body you made need to consume 10-20 times more carotenes to create the same amount of true vitamin A.

Vitamin A is a family of fat-soluble compounds that plays an important role in vision, bone growth, reproduction, cell division, proper prenatal development and cell differentiation. Vitamin A is important for healthy bones and together with vitamin D stimulates and regulates bone growth. Vitamin A lowers blood serum calcium. This is an indication that vitamin A is helping your body utilize calcium. Vitamin A increases growth factors, which stimulate bones and teeth to grow and repair.

Large doses of vitamin A can be toxic. However any negative effects of vita­min A seem to be blocked when sufficient vitamin D is in the diet.” Therefore if you eat a lot of liver from land animals, make sure you are getting plenty of sunlight or vitamin D to prevent vitamin A toxicity.

In examining this list, you will see that liver is the most concentrated source of fat-soluble vitamin A. The magic of liver in relation to healing tooth cavities in part is its high vitamin A content.

Vitamins A and D from Foods

If you have tooth decay, you are presumably deficient in vitamins A and D. To make up for a deficiency more of these vitamins will be required at the begin­ning of your dietary change. It is difficult to know without thorough testing and scientific understanding the exact amount of vitamins A and D your body needs. That is why you will have to adjust your dosages of fat-soluble rich foods based upon how you feel. Using Dr. Price’s program as a guide, we want at least 2,500 IU’s of vitamin D per day, and at least 6,000 IU’s of vitamin A. You can obtain these fat-soluble vitamins either from food, from cod liver oil, or from both. First we will look at our food options.

My experience has been that for most people, but not everyone, we are greatly underestimating our needs for these vitamins, so much higher dosages than rec­ommended here might be in order if it feels right to you.

Three Different Sample Daily Food Groups for Fat-soluble Vitamins A and D

2 tablespoons of tallow (suet) approx. 500 IU vitamin D 3/4 pound sockeye, king, keta salmon 2616 IU vita­min D 4 duck eggs 2100 IU vitamin D, 1888 IU vitamin A
3.5 ounces of sockeye salmon 763 IU vitamin D 1/2 pound goat cheese 3,600 vitamin A 1 ounce of chicken liver 3808 IU vita­min A
6 chicken eggs 800 IU vitamin D 2 tablespoons butter, 750 IU vitamin A
1 ounce beef liver 10,000 IU vitamin A
