Iron is a well-known mineral associated with strength, energy, and immunity. Though most Americans get adequate amounts of this nutrient, iron deficiency is the most widespread nutrient deficiency in the world – affecting 30% of the population!

What is iron?

Iron is a key component of red blood cells and enables them to carry oxygen throughout the body. It also provides oxygen for storage and use by our muscles through a protein called myoglobin.

What benefits does iron have in the body?

Iron’s most important role is in carrying oxygen throughout the body; as such, it provides us with the ability to perform both normal, daily routines as well as higher intensity exercise. It also allows transport of oxygen to the brain for focus, concentration, and memory. Due to iron’s involvement in numerous other processes, it also contributes to immune system health and aids in regulating body temperature.

How much do I need?

Needs vary based on age, gender, activity, and dietary choices. Recommended daily intake of iron is 8 mg for all men and for post-menopausal women; 18 mg for pre-menopausal women. 27 mg/day is recommended during pregnancy. Daily intake of up to 45 mg/day is safe for most people; typical intake is 10-20 mg/day.

In the US, about 8% of adults obtain less than recommended. Prolonged iron deficiency leads to anemia, which occurs in about 5% of women and 2% of men. Athletes, vegetarians, and vegans need more iron than the general population, but for different reasons. Both competitive and recreational athletes lose iron through perspiration; those who exercise at high levels of intensity, especially endurance runners, lose iron through faster red blood cell breakdown. Vegetarians and vegans require more iron because plant-based sources are only about half as well absorbed as those from meat.

How do I best obtain iron?

Iron comes in two forms: heme- and non-heme iron. Heme iron comes from hemoglobin and is found in animal-based foods; this form is much more readily absorbed by the body than non-heme or plant-based iron. High sources of heme iron include liver, oysters, mussels, sardines, and beef. Foods like chicken, turkey, and pork provide lesser quantities but are still well absorbed.  Non-heme iron sources come from plants and are about half as well absorbed as meat-based sources. Tofu, beans, fortified cereals, dried apricots, nuts, and seeds contain the highest levels of non-heme iron. Dietary supplements are another way to increase your intake of iron.

Do your products contain iron? If so, how much?

Yes, Nutriex Sport, Health, and Basic37 all contain 6 mg of iron in a full serving (9 capsules of Sport, 7 capsules of Health, 2 capsules of Basic37). We chose the 6 mg quantity to get the average person at or slightly above their daily requirement without exceeding a safe level for men or older women.

What is unique about the iron in Nutriex products?

Nutriex products contain a patented, chelated form of iron called Ferrochel ferrous bisglycinate chelate. Simply put, this chelated form of iron is electrically neutral (carrying neither a positive nor negative charge), which not only makes it stable, but also keeps it from binding to other nutrients and enables good absorption. It is gentle on the digestive system and does not cause GI irritation or constipation unlike many other iron supplements.

Is it safe for me to take supplemental iron?

The amount of iron in Nutriex products is safe for nearly everyone, men and post-menopausal women included.  Because our bodies have a special mechanism to self-regulate the amount of iron that is absorbed (via production of a hormone called hepcidin), we automatically absorb more when we need it and less when we don’t. Those with hemochromatosis, an inherited condition that typically affects non-Hispanic whites, lack this ability to regulate iron absorption; a small subgroup with this condition can accumulate excess stores of iron that can lead to liver and heart damage or diabetes. This group should NOT supplement with high levels of iron and should work with their physician to monitor their iron status. People with documented low blood iron levels or anemia should consider short-term additional iron intake, whether from food or supplements.

Coenzyme Q10

What is CoQ10?

Coenzyme Q10, also known as CoQ10, is a powerful fat-soluble antioxidant that works throughout the body. In addition to its antioxidant capabilities, CoQ10 plays an important role in converting food into energy. Originally called ubiquinone because it is ubiquitous (seems to be everywhere) in nature, all animals, including humans, are capable of making CoQ10.

What benefits does CoQ10 have in the body?

The most important benefit of CoQ10 is as an antioxidant, which means it protects cells throughout the body from waste products called free radicals by “neutralizing” them. CoQ10 also plays a key role in healthy heart and blood vessel function – two key components of the cardiovascular system. Very importantly, CoQ10 helps to recycle both Vitamin C and Vitamin E, allowing them to be utilized by the body over and over again.

How much do I need?

Because our bodies naturally produce Coenzyme Q10, outright deficiency is extremely rare. As such, there is technically no recommended intake for this nutrient. Because production decreases as we age, beginning at around age 40, supplementing with CoQ10 allows more to circulate throughout the body for use by the organs and as an antioxidant to promote healthy aging.

How do I best obtain Coenzyme Q10?

Some foods contain small quantities of CoQ10. Meats are the best food sources of CoQ10, though it is also present in oils, nuts, and to a lesser extent, in vegetables and fruits. Typical intake from food is only 3-6 mg/day. Supplementation is the best way to obtain larger quantities.

Do your products contain Coenzyme Q10?  If so, how much?

Yes, Nutriex Sport, Health, and Basic37 contain 50 mg, 40 mg, and 20 mg of CoQ10, respectively, in a full serving (9 capsules of Sport, 7 capsules of Health, 2 capsules of Basic37).

What is unique about the CoQ10 in Nutriex products?

CoQ10 is best absorbed when consumed at the same time as fat, so it should 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 nutrients. CoQ10 may be even better absorbed with more fat than is present in the vitamins themselves, so consider taking them with a meal if maximal absorption of CoQ10 is important to you.

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.
