Vitamin D

What is Vitamin D?

Vitamin D is a fat-soluble vitamin that works throughout the body and is involved in countless roles involving the immune system, bone health, heart health, and normal cellular growth.

What is the effect of Vitamin D on COVID-19 and other illnesses?

First off, vitamin D does not prevent COVID-19.  But we do know that people who are deficient in it are 1) more likely to test positive for COVID-19, 2) experience severe illness from COVID-19, and 3) more likely to experience an increased severity of other respiratory illnesses.

How much do I need?

Experts recommend total serum 25-hydroxy-vitamin D levels of 30-50 ng/mL from a blood test. Higher levels can be beneficial in certain situations, though levels above 50 ng/mL can have a negative impact on some individuals. If you are already in the 30-50 ng/mL range, you can likely maintain it by supplementing with 20-50 mcg (800 – 2000 IU) of vitamin D3. Higher daily quantities (125-250 mcg or 5-10,000 IU) are generally safe but not necessarily beneficial for most people.

Which form of Vitamin D is best? How do I best obtain it?

Vitamin D3 supplements are the most reliable source. Vitamin D can be obtained from food and is highest in fatty fish (hence the beneficial reputation of cod liver oil) and in smaller amounts from mushrooms, meats, and eggs. Milk is fortified with it at levels of 2.5 mcg or 100 IU per cup; most plant-based milks are fortified as well. Humans naturally produce Vitamin D when their skin is exposed to UV-B light from the sun, but production varies substantially by season (summer much higher than winter), skin color, latitude (northern locales yielding less), age, and sunscreen use and is not a reliable way to get adequate amounts.

Does Nutriex contain Vitamin D? If so, how much?

Yes, Nutriex Sport, Health, and Basic37 all contain 25 mcg (1,000 IU) of Vitamin D3 in a full serving (9 capsules of Sport, 7 capsules of Health, 2 capsules of Basic37.)

What is unique about the Vitamin D in Nutriex products?

Vitamin D is best absorbed when consumed at the same time as fat, so it is recommended to be consumed with a meal. Nutriex products are unique because they already contain fat (in the form of flaxseed oil), so you can take them with or without food and still obtain the benefit of being able to absorb the fat-soluble vitamins like Vitamin D.


What is turmeric?

Turmeric is a spice that comes from the root of the turmeric plant. There are components in turmeric called curcuminoids that produce not only the bright orange color, but are also powerful antiinflammatories and antioxidants. They as well as the essential oils naturally present in turmeric are the components thought to provide turmeric’s health benefits related to digestion, joints, mood, skin, and tolerance to seasonal pollens.

Do Nutriex products contain turmeric or curcumin?

Yes, Nutriex Sport, Health, and Basic37 all contain curcumin from turmeric. We include 25 mg in Sport and Health; half that in Basic37. The source of turmeric we use is extremely well absorbed (see below), so you obtain the same benefits you would receive if you took 7 times that amount of a standard turmeric supplement.

What is unique about the turmeric in Nutriex products?

We use a source of turmeric called BCM-95, a 100% turmeric product without other additives. It is concentrated as a 95% curcuminoids complex (86% curcuminoids and 9% essential oils). This unique combination provides both high levels of curcuminoids as well as essential oils including turmerone, to provide benefits from a spectrum of nutrients rather than just one active ingredient. It’s been clinically studied to be absorbed at least 7 times more efficiently than standard forms of turmeric. BCM-95 circulates in the blood and is available for use for a full 8-9 hours after consumption, unlike other products that clear the body in 1-2 hours.
