High Potency Vitamin D
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.*

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.*
Q: How much vitamin D do I need per day?A: 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.
Q: Is it possible to take too much vitamin D?A: 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.
Q: Is it better to get sun than to take supplements?A: 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.
Q: Can I get vitamin D through food?A: 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.
Q: How long does vitamin D stay in the body?A: 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.

Rate this productI lack vitamins derived from sunshine because I like in NYC and work full time- definitely making this supplement a staple.
Rate this productPrimal Sun has helped my family get through the winter months. Hubby calls them his 'happy pills.'
Rate this productWe live in the Midwest and the sun rarely shines in the winter. I take extra vitamin D to help with my mood. I've been happy with this product.
Rate this productI've bought Primal Sun at least twice, maybe three times, now. Living in daylight-deprived Alaska, it's the one supplement I take without fail every day. I've bought a million brands over the years, but keep coming back to Primal Blueprint.
I trust Mark Sisson, maybe it's as simple as that. I trust that he's choosing good ingredients, and that he's not ripping anyone off. Think about it, how many years now have we been getting priceless information from Mark's Daily Apple -- for free???
I believe in supporting companies that are working to do the right thing for their customers and clients. I've no doubt in my mind that Primal Blueprint is all of that and more.
Rate this productAs expected
Rate this productLiving in the northeast, if I don't take my vitamin D regularly during the winter I quickly feel it in my mood, energy and motivation. I know that Mark only sources the best quality ingredients and even better, he only produces in small batches so I know that when my next bottle arrives, it hasn't been sitting in a warehouse somewhere for the last 18 months. Even better, now that he's switched to the larger bottles, I don't have to feel as guilty about so much shipping and packaging.
Rate this productStocked up on this for the winter when the sun is hiding a bit more here. Taking the max dose helps keep D levels up and keep immunity up along with other benefits.
Rate this productI use primal sun and omega in conjunction with the primal diet. Although it is hard to see the unique effect of primal sun since I am not doing a controlled experiment, it feels good overall. I see a huge boost to my immune system during common cold days. When ever I suspect signs of common cold or flu, the primal sun helps control that. i used to have common colds frequency in the past.. Not any more.
Rate this productI'm frequently outside during the warmer months but once it dips below freezing my activity is somewhat restrained. This, combined with some K2 tablets are a part of my daily regimen in the colder months.
Rate this productGreat way to supplement your sun intake, especially during the colder months. Customer service second to none!
Rate this productVery easy for Amy body to digest
Rate this productThis stuff seems to work fine. It's difficult to tell for me without having a lab or without having some kind of medical condition thst vastly swings one way or the other in response to certain vitamins. However, these days I work an 8-5 and have had skin cancer several times, so to say the least I don't spend as much time in the sun as I used to, so for my situation supplement makes sense. And Mark is a good guy so I trust his products are legit.

Rate this productWe are pleased with this product. We feel good about all of the Primal Blueprint products because of their commitment to excellence in sourcing.
Rate this productFirst- let me say my background is in biology (molecular/cellular) and with grad studies in nutrition- this is a great product. The omegas are 1 SG daily. The source of the fish oil is good (see facts on site) and the repeat is minimal. All oils repeat to some extent, but this is very minimal and almost non existent when taken with food. I like that the care was taken with the packaging to shield the product from sunlight as we often leave them near windows etc. The vitamin D is not a SG which was surprising but I love that it contains D2 and D3- it's rare to find one of such quality. I wish it was a little higher in potency or offered the such an option, however the quality makes up for the lack of options. Something for the company to consider going forward. Overall, they are great products. If you'd like to learn more they have outstanding information with regards to the supplements on the site. Always important to keep in mine these things are "supplements" hence used to "cover" or compensate for what we are not getting from our food/nutrition.
Rate this productI've been taking these consistently and my dentist says my teeth are pretty healthy.
