Benefits of Vitamin D

Our Honest Assessment

Ic research verystrong

Very Strong Research

Vitamin D is essential for general health and for strong bones. Deficiency is rare, but has serious health consequences, like rickets.

A 2011 study showed that over 70% of Americans get less than the daily recommended amount of vitamin D. If you don't get a lot of sun - which helps your body produce vitamin D - or if your diet is low in foods that contain it, you may be among them. Foods that contain vitamin D are fatty fish, beef liver, and fortified milk and cereal.

Supports bone health

Ic topic bone

Adequate intake of vitamin D is essential to maintain healthy bones. Vitamin D is necessary for calcium and phosphorus absorption, which is why it is a major component of bone health. Ingesting adequate calcium and vitamin D throughout life as part of a well-balanced diet may reduce the risk of osteoporosis.

Absorbed from the sun

Vitamin D is found in our diet, but we also produce it through exposure to sunlight. However, a number of factors impact the ability for people to get necessary levels of vitamin D through sun exposure.

Regional factors that prevent people from getting sun exposure include cloud cover patterns, smog, and the angle with which the sun hits the earth. In cities north of 37 degrees latitude (imagine a line drawn between San Francisco and Richmond, VA), it’s hard for people to produce enough vitamin D from sun exposure, especially between the months of November and March.

The ability for skin to absorb light also impacts how well people can produce vitamin D, as does the use of sunscreen and the number of hours per day spent inside. It should be noted that UVB rays necessary to produce vitamin D do not penetrate glass, so sitting near a window indoors won’t help you produce sufficient vitamin D.

Our Vitamin D

Fermented for absorption

Our Vitamin D is fermented with probiotics and organic foods, which gently cultures nutrients into an easily digested, highly active form that is easier for your body to absorb. In contrast, most vitamin D products are isolates, which are less bioavailable.

Made in the U.S.

Our fermented Vitamin D is manufactured and encapsulated in the United States. We then issue a number of tests to ensure that the final product contains the correct levels of active ingredients and meets NSF standards on quality and safety.
