Vitamin D
Sunny D
- Strengthens bones
- Increases the production of testosterone
- Improves insulin secretion and sensitivity
- May reduce the risk of cardiovascular disease

Non-GMOIf you don’t get a regular dose of sun (for example you avoid the sun, always wear sunscreen or don’t live near the equator), you may not be getting enough Vitamin D. Vitamin D can help reduce the risk of cardiovascular disease, fix calcium to bones, increase insulin secretion and regulate testosterone levels.
Our Vitamin D is in its D3 form, which is the natural form of Vitamin D your body makes from sunlight and therefore is more bioavailable than D2.

One of the prominent symptoms of Vitamin D deficiency is rickets, a condition characterized by bone abnormalities and reduced bone density.[1] Another more common deficiency-linked disease is osteoporosis.[2] Studies indicate that supplementing Vitamin D daily can also improve muscle strength, thereby significantly decreasing the risk of fall and consequential bone fractures. Studies concluded that doses higher than 700 IU per day were required and protection from falls could be enhanced by supplementing with Calcium, and potentially Vitamin K, at the same time.[3]

Testosterone is a key steroid hormone produced by both men and women. This hormone stimulates the growth and development of bones, muscle mass, and even improves libido and mood.
In women, testosterone is an essential precursor to estrogen and helps grow, support and protect reproductive tissues[4] as well as maintaining bone mass[5] and mood.
In men, a deficiency in Vitamin D has been linked to hypogonadism, a condition where the body ceases to produce sex hormones.[6] Vitamin D receptors can be found on sperm cells and may also play a role in the production of steroid hormones. As we age, testosterone production naturally declines, but recent studies suggest taking Vitamin D could help delay this occurrence.[7]
Illustrative Studies
In a study on men with low Vitamin D levels, supplementing Vitamin D3 over the course of a year led to an increase in testosterone levels. Since the participants were all middle-aged men, however, they may have started the experiment from a state of age-related testosterone decline. The effect of Vitamin D supplementation on younger men is currently unknown.[8]
Research Score: Strong
Several studies indicate that supplementing Vitamin D may reduce the risk of cardiovascular disease and secondary complications.[9] [10] There is also mixed evidence with regards to Vitamin D lowering blood pressure. Where there are positive results, the degree is quite small.[11]
Research Score: Mixed
Studies in both men and women have noted that supplementing Vitamin D can improve insulin secretion and insulin sensitivity in diabetics (type II mostly) and in persons at risk for diabetes, which is thought to be secondary to increasing insulin secretion of the pancreas.[12] [13]
