Primal Sun


Chances are you're not getting enough sun every day. Vitamin D supplementation can help with cancer protection, increasing nutrient absorption, optimizing hormonal function, boosting immune function, and reducing inflammation. Primal Sun is a pure and potent source of Vitamin D that offers the protection you need.

Why Use Primal Sun?

Why Use This

The sun is our primary natural source of vitamin D, but the vast majority of adults do not get enough sun exposure. Recent studies continue to confirm vitamin D as a “superstar” nutrient crucial for good health. (Fun fact: it’s actually not a regular vitamin but a steroid hormone.) Vitamin D not only regulates levels of calcium and phosphate in the bloodstream, but also works together with calcium, vitamin A and vitamin K2 to promote the mineralization and growth of bones. Vitamin D plays a massive role in the immune response, activating and “arming” the killer T-cells for defense against infections and bacteria. It modulates the expression of genes that regulate cell proliferation, suggesting a potential role in cancer incidence, and it reduces systemic, chronic inflammation. And yet it is one of the most chronically deficient vitamins in Americans today! Vitamin D insufficiency has emerged as a disastrous pandemic, contributing to a rise in cancer, autoimmune diseases, mental health conditions, etc. Chances are you’re not getting enough sun every day, and Primal Sun is the perfect way to supplement your intake.*

Key Benefits

  • Boosts the Immune System
  • Supports Strong Bones
  • Helps Reduce Inflammation*

Promotes Strong Bones

Essential vitamin D helps regulate levels of calcium and phosphate in the bloodstream and promotes the mineralization and growth of bones by working together with calcium, vitamin A and vitamin K2.*

Supports the Immune System

Severe vitamin D deficiency (50% of the population is at risk for vitamin D deficiency!) can cause rickets. Vitamin D plays a massive role in the immune response, activating and “arming” the killer T-cells for defense against infections and bacteria. It modulates the expression of genes that regulate cell proliferation, apoptosis and differentiation, suggesting a potential role in cancer incidence.*

Helps Reduce Chronic Inflammation

Epidemiology suggests links between vitamin D deficiency and most cancers, including breast and colorectal. Vitamin D helps protect against cancer, and also heart disease, in part because it reduces systemic, chronic inflammation.*

Frequently Asked Questions

How much vitamin D do I need per day?

Since 2010, the recommended daily allowance of vitamin D has fallen between 400 and 800 IU per day, but new research suggests adults may actually need at least 2,000 IU of vitamin D every day, and the best source of vitamin D is from the sun! It is estimated that the human body is able to produce 10,000 IU to 20,000 IU of vitamin D3 from as little as 30 minutes of sun exposure. However, the majority of adults do not get even 30 minutes of regular sun exposure. Subsequently, vitamin D deficiencies are rising among all age groups in the U.S. Vitamin D food sources, such as salmon, egg yolk and raw milk, only provide around 200 IU to 400 IU of vitamin D, which is why most adults would benefit from vitamin D supplementation.

Is it possible to take too much vitamin D?

Taking too much vitamin D is called vitamin D toxicity, but such a scenario is highly unlikely. You’d have to take 40,000 IU per day for a couple of months or longer to be in danger of developing vitamin D toxicity.

Is it better to get sun than to take supplements?

Take stock of your living situation. If the sun is pretty much a constant where you live, then opt for some actual rays whenever possible. It’s free, it’s safe, it’s easy and it’s enjoyable! For those of you who work in an office or live in a colder climate, supplementation is an easy and effective way to ensure adequate vitamin D levels.

Can I get vitamin D through food?

Certain foods are touted as vitamin D powerhouses: wild salmon, mackerel, herring, catfish, cod liver oil and eggs. Each of these foods is an excellent primal approach to eating, but won’t significantly enhance vitamin D levels. If your vitamin D levels fall within the danger zone (less than 40 ng/ml), then supplementation is strongly advised.

How long does vitamin D stay in the body?

It’s believed that when taken orally vitamin D has a half-life of one month. Because excess vitamin D is stored in fat, some vitamin D can remain in the body for an extended period of time to be used during months when access to the sun is limited, such as the winter season.

How long is the shelf life for this product?

It maintains optimum potency for up to 18 months.

How do you manufacture vitamin D3?

Vitamin D3 is manufactured by irradiation of 7-dehydrocholesterol from lanolin (from sheep's wool) and the chemical conversion of cholesterol. We have found that while D3 seems to be preferred by most, some people just can't absorb it well, so we offer both forms in Primal Sun.
