Vitamin D is absolutely critical for our health and it is estimated that up to 50% of the population is deficient. There are various forms of vitamin D, but we supplement with D3 because it is the more naturally occurring form of the vitamin and may raise levels more effectively.
D3 comes from sunlight and food. When sunlight hits our skin, it converts a precursor called 7-dehydro-cholesterol to vitamin D3. This D3, with the D3 we get from our food is converted by the liver into 25-hydroxy-vitamin D, which is what is measured on a lab test. Since seafood is the most significant source of D (which is an issue in and of itself given the amount you’d have to eat and the heavy metal toxicity exposure) and sunlight is hard to come by during the winter months, it is very easy to become deficient.
Liquid Vitamin D3 with MCT Oil is an isolated vitamin D3 supplement that provides 2,000 IU per drop. MCT oil is used to increase the bioavailability because vitamin D is a fat soluble vitamin. You’ll notice that this supplement does not contain vitamin K, that is because humans are adapted to get their nutrients from whole foods and outside of select conditions (like heart disease and unique health conditions that affect menopausal women), it is more ideal to supplement with D3 and obtain K (in its various forms) from your diet.
