Vitamin D Levels
Confusion Over Vitamin D Levels
We know that vitamin D is a crucial part of our physiology, affecting over 3,000 of our genes. As a fat-soluble vitamin, it maintains a delicate balance with vitamins A, E and K, the remaining vitamins in this family. But what we’ve done is isolate and focus on only one member of the family without taking into consideration all the others. And that’s never a good thing.
I don’t know about you, but I have never had a patient walk into my office and ask me about their vitamin A levels. Once in a while, someone will make mention of vitamin K being important but they have no idea why. Only that Dr. Google said so.
Research on optimal vitamin D levels has been all over the board. Initial testing was done on the inactive form, 25D, assuming that everyone would be able to make the conversion into the active form 1,25D. But this is not necessarily true. Conversion of vitamin D requires several other nutrients and vitamins not to mention a healthy gut, which all by itself, can be a deal breaker.
But here’s my take on vitamin D.
Best dietary sources are green veggies and grass-fed animal products such as meat, cheese and organ meats. These will also provide some of the other fat-soluble vitamins as well, keeping the family of vitamins stable and functional together. If your patient is not able or willing to consume animal products then supplementation may be necessary. Adding Cataplex D (6/day) along with Chlorophyll Complex for the K (4/day) is a great start. And remember, fat soluble vitamins can become toxic as they can be stored rather than easily eliminated like the water soluble vitamins.
Optimal levels really should be around 30-35. Some research even shows that levels as low as 25 are more protective. But I think if we shoot for the middle, we should be right on the mark. It is also important to take into account limiting factors involving sun exposure (latitude, skin tone, amount of time actually in the sun, time of day, etc) when deciding on how much supplementation you may actually need.
