– Dr. Jayson and Mira Calton, Inventors of nutreince, Founders of Calton Nutrition

A superior active source of vitamin B12 (Methylcobalamin)

The standard source of B12, Cyanocobalamin, is not a natural source. In fact, its not found anywhere in nature and must be converted by the liver into methylcobalamin in order be become utilized in humans (and all other animals). Cyanocobalamin is typically found in products such as Centrum and One-A-Day (see compare nutreince…) Methylcobalamin is the form of vitamin B12 active in the central nervous system. It is essential for cell growth and replication making it the best choice for nutreince! (26) *

Natural Tocopherols and Tocotrienols

Vitamin E is split into two families the tocopherols and the tocotrienols, each containing four unique derivatives (alpha, beta, gamma, and delta). Nutreince contains the full spectrum of each. Additionally, nutreince supplies a natural source of mixed tocopherols (vitamin E) not a synthetic source of alpha-tocopherol (just one of four tocopherols).(28) According to research published in the American Journal of Clinical Nutrition researchers found that levels of natural vitamin E (d-tocopherol) in the blood and in the organs were double that of synthetic vitamin E (dl-tocopherol) when compared, showing natural vitamin E is better retained and more biologically active than synthetic.(29) *

6 milligrams of Lutein + Astaxanthin

Most multivitamins do not contain lutein or astaxanthin at all, but we have added 6 mg of lutein and 100 mcg of astaxanthin to nutreince because this is the amount that is recommended to prevent/reverse Macular Degeneration (AMD) and protect against blue light. (18) *

The most biologically active form of Folate, L-5-MTHF

Nutreince contains 400 mcg of the most biologically active form of folate, L-5-MTHF (Quatrefolic), a breakthrough in folate supplementation. L-5-MTHF does not require conversion like folic acid. Research published in the American Journal of Epidemiology shows that more than 34% of the U.S. population may have a genetic enzyme defect known as MTHFR mutation that makes it difficult for them to convert folic acid into biologically active L-5-MTHF, and new estimates suggest that up to 60% of the population may be affected. For these individuals and many others, L-5-MTHF may be a more effective method of folate supplementation.(17) *

Vitamin D – the skinny vitamin

Nutreince includes 2000 IU of vitamin D, the amount emerging science is currently recommending for optimal health and in the best D3 form. Individuals deficient in vitamin D, which is now being touted as the “skinny” vitamin, are at a higher risk of obesity. A study from Children’s Hospital in Los Angeles found that women who were deficient in vitamin D were, on average, 16.3 pounds heavier than women who were not vitamin D deficient. Vitamin D deficiency has also been linked to cancer, diabetes and cardiovascular disease.(37) *

Both forms of vitamin B3 – Niacin and Niacinamide

Most multivitamins only contain niacinamide. However, the two forms of vitamin B3 perform completely different functions in your body. Niacinamide controls blood sugar, but only niacin, a completely different form of vitamin B3 that is usually not found in multivitamins is the form that has been shown to lower LDL (bad cholesterol) and raise HDL (good cholesterol). nutreince contains both forms because when we say complete – we mean it!(27) *

Powerful Antioxidant Formulation

We hear a lot about the importance of antioxidants, and how they can control how fast we age by fighting free radicals. That is why we took the time to formulate nutreince to have a super powerful antioxidant punch! By combining some of the worlds most powerful antioxidants, including quercetin, grape seed extract, CoQ10, vitamin E, lutein, beta-carotene, selenium, zeaxanthin, vitamin C and astaxanthin into each daily dose, we exponentially enhanced your ability to fight free radicals and enhance your health.

Preformed vitamin A and beta-carotene, Astaxanthin, and Zeaxanthin

Some multivitamins only contain beta-carotene – an inactive form of vitamin A (pro-vitamin A), which must be converted in the body to retinal (preformed) – an active form (conversion rate of 21:1)(32) – nutreince gives you both forms of vitamin A and also contains super antioxidants astaxanthin and zeaxanthin. 

500 mg of Calcium

Unlike almost any other multivitamin on the market, nutreince delivers 500 mg of calcium in each daily dose. This is the optimal amount of calcium that can be absorbed by the body at one time. Creating sufficiency in calcium not only helps to build strong bones and prevent fractures, but research also shows that it eliminates cravings for salty and sweet foods as well. (34) *

Bone building and calcification clearing elite form or vitamin K2

Vitamin K is often omitted from many multivitamin formulations, but is essential for bone strength and heart health. Nutreince contains vitamin K1 and both forms of K2 (MK-4 and MK-7), but goes one step further by including K2Delta an elite form of MK-7 that does not lose its potency due to micronutrient competition like other K2 products. This is extremely important if you have osteopenia or osteoporosis, in that vitamin K2 has been proven in studies to be as effective as prescription drugs in reducing the incidence of bone fractures. (12) Additionally, because K2 directs the calcium out of the arteries and into the bones where it is needed, an elite form of K2 is essential for the prevention of coronary heart disease.(38) *

Statin safe quantities of vitamins C and E

Science has shown us that more is not always better when it comes to the amount of vitamin C and E one should be taking if they are currently taking a statin drug. The anti-inflammatory effect of cholesterol-lowering statin drugs can be inhibited by taking mega doses of either vitamin C (>220 mg) or E (>100 IU). Nutreince contains only the RDI of both of these vitamins, well within the safe rage for statin takers.

Metabolically active forms of B1 and B5

Most multivitamin contain forms of thiamine (vitamin B1) and pantothenic acid (vitamin B5) that need to be converted in your body to their active form. The fact is most people have a hard time with these conversions, leaving them susceptible to deficiency. Nutreince contains thiamine pyrophosphate and pantethine – the metabolically active forms of B1 and B5, which do not require conversion and are readily usable by the body. Since both of these B vitamins are essential for energy production, using these superior forms can really enhance your ability to go, go go!* 

CoQ10 (aka Coenzyme Q10)

Here is a micronutrient you won’t find on the label of most multivitamins – it is just too expensive to include! But we need CoQ10 to combat free radicals, maintain a healthy blood pressure, support our nervous and immune systems and to energize every cell in our body. And for those of you who are taking statins it is essential for you to replenish your CoQ10 levels because statin drugs directly deplete CoQ10.(33) *

420 mg of Magnesium

Most multivitamins supply small amounts of magnesium because of its bulky size. Nutreince supplies 420 mg of magnesium, a micronutrient responsible for over 300 essential metabolic reactions in the body as well as controlling sugar cravings.(35)(36) Nutreince contains magnesium citrate - one of the most bioavailable forms to help you protect your bones, support healthy blood pressure and sleep soundly.

Chromium polynicotinate (not picolinate) and vanadium

Nutreince contains the safest, most absorbable form of chromium—chromium polynicotinate. Unlike chromium picolonate, which research suggests may be linked to causing DNA damage, chromium polynicotinate is a pure niacin-bound form of chromium, identified by U.S. government researchers as the active component of true GTF (Glucose Tolerance Factor) – which regulates the body’s use of glucose and helps to balance blood sugar levels. Vanadium, a mineral that studies suggest may improve glucose tolerance is also added to nutreince. (39) *
