Vegan living is on the rise as a preferred, conscientious lifestyle. But, whether you are vegan or not, vegan vitamin D just makes good nutritional sense.
Did you know that most Vitamin D3 comes from lanolin?
The Nature of Lanolin
Lanolin, also known as wool grease
, is the waxy substance that naturally occurs on sheep’s wool. Yes, sheep are so cute. But they wear a collection of manure, dirt, and they may have been sprayed with pesticides to treat for mites. Poor sanitation is one of the main causes of disease in sheep.
After shearing, the wool is scoured with soap or detergents. The remaining liquid is centrifuged (spun at a high speed) and refined. The result is lanolin.
Sheep are pasture fed during grazing season. Off season they get combinations of:
- Corn or corn gluten
- Soybean meal
- Dry Distillers Grains (DDGS)
- Soybean hulls
About 3/5 of production cost is feed. To save on feed cost, corn or other grain may be bought when the price is low and stored in silos. If not properly stored, grains can develop mold, which leads to diseased sheep.
Food additives include things like:
- Urea as a source of nitrogen
- Blood meal for protein
- Feather meal (denatured feathers) as a nitrogen source
From Top To Bottom
Lanolin can be found in almost anything that goes on our skin, from eye liner to body lotions, and hemorrhoid treatment to diaper rash cream. So, top to bottom, we might be saturating ourselves with lanolin, and not even know it.
Since wool generally does not come from organically raised sheep, GMO’s and endocrine disrupters are making their way into the consumer’s blood stream.
How Much Vitamin D Is Enough?
The answer is not only about how much to take, but also about getting a formulation your body can use. Vitamin D3 helps the body absorb calcium. Vegan D3 is better, but by itself it isn’t all your body needs.
To ensure the calcium gets into the bones and teeth, the body also needs Vitamin K2. Without the two essential forms of K2 (MK-4 and MK-7), calcium goes to the heart and blood vessels.
