D3 is an extremely important and powerful hormone, linked to hundreds of metabolic processes. From bone health, to blood pressure, to fatigue and mood, to blood sugar management, low levels of D can have a negative and far ranging effect on our overall health and sports performance. And depending on the study you review, as many as 70% of North Americans and Europeans are deficient.
D3 is manufactured by the body during exposure to sunlight. The further away from the equator your are, and the less time you spend outdoors with large amounts of exposed skin, the less D you can manufacture. Obtaining D3 through food is extremely difficult, and impossible at the levels many people are finding helpful.
This supplement is an extremely high quality D3 at 10,000 IU per dropper, suspended in a light orange oil. With almost no taste you can dose directly into your mouth or add to a salad or smoothie.
