Why Use Primal Sun?

Why Use This

Your body produces Vitamin D naturally when ultraviolet rays from sunlight strike the skin. It’s great to get outdoors as much as possible. However, many people don’t spend a lot of time out in the sun, or they live in climates where direct sunlight is hard to come by for parts of the year.

You can obtain some Vitamin D from your diet, but only a limited number of foods naturally contain vitamin D. These include wild salmon, mackerel, herring, catfish, and cod liver oil. Liver and eggs contain small amounts of Vitamin D as well, and some products are fortified with Vitamin D.

Supplementing with Primal Sun can help boost your Vitamin D intake.

For adults, take one (1) capsule daily, preferably with a meal.

vitamin D

Spending time indoors due to COVID. I am a teacher and have made the transition to virtual schooling requiring me to be online daily. Little time to get outside. New vitamins are helping.

Great Product

I’ve had trouble in the past with vitamin D causing headaches. Even though I get plenty of sun and live in the south, my D levels remain low. This is the first D supplement that I have been able to tolerate. Thank you.

Quality source of Vitamin D as the PNW heads toward winter

I live in the Pacific Northwest of the US and as the days are getting shorter as winter approaches, I need a quality source of Vitamin D. I know Mark stresses the importance of bioavailability of the various supplements available out there, so I know I'm getting a quality product when I order Primal products.

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.
