Because our vitamin D supplement is organic mushroom-based, it naturally contains elements like beta-glucans and polysaccharides that are immune-stimulating. Not only are you naturally getting those, but you're also getting C and B vitamins, several minerals: copper, iron, iodine, potassium, magnesium, manganese, selenium, zinc, all from the mushroom. Beta-glucans and magnesium are the most critical for supporting your health.
In order for vitamin D to have a great health impact, two vital things must happen. One, vitamin D must be absorbed into your bloodstream. That won't happen without help, so we added enzymes and probiotics to our vitamin D. Most supplements don't do that. Two, the vitamin D must be activated by your body chemistry. Magnesium is the only component that can activate vitamin D in your body. When you take another vitamin D supplement, you are most likely not getting a true plant-based product, and they don't include magnesium for activation. Also, without the probiotics and enzymes, you will not be able to absorb a healthy amount of vitamin D. So, without those four elements, vitamin D is most likely not being used by the body.
Research links low levels of Vitamin D to frequent infections and the worsening of autoimmune diseases. Studies also indicate that taking a vitamin D supplement is a safe way to protect against respiratory infections. (7,8)
