Why Choose nutraMetrix Isotonix® Multivitamin With Iron*


A good quality vitamin and mineral supplement creates a sound micronutrient foundation to accompany a balanced diet. According to the World Health Organization (WHO), “Nutrition is the foundation for health and development. Better nutrition means stronger immune systems, less illness and better health. Healthy children learn better. Healthy people are stronger, more productive, and more able to create opportunities to gradually break the cycles of both poverty and hunger in a sustainable way. Better nutrition is a prime entry point to ending poverty and a milestone to achieving better quality of life.”

Vitamins and minerals help to support a healthy immune system, promote the conversion of food into energy, support a healthy cardiovascular system, support strong bones, promote mental clarity, maintain normal metabolic functioning, promote healthy growth and repair of tissues, help maintain normal blood pressure and help maintain water and electrolyte balance in the body. There is no substitute for a healthy, well-balanced diet; however, in today’s fast-paced lifestyles it is important to ensure the body is getting the fuel it needs.*

nutraMetrix Isotonix Multivitamin is an isotonic-capable food supplement containing 100 percent or more of the daily value of essential vitamins and minerals. There are wide varieties of vitamin and mineral supplements on the market today. Only Isotonix Multivitamin contains a unique blend of complementary vitamins and minerals with the superior delivery of Isotonix. nutraMetrix Isotonix Multivitamin supplements dietary deficiencies and helps maintain normal metabolic functioning. nutraMetrix Isotonix Multivitamin is available with and without iron for differing nutritional needs.*

Isotonic, which means “same pressure,” bears the same chemical resemblance of the body’s blood, plasma and tears. All fluids in the body have a certain concentration, referred to as osmotic pressure. The body’s common osmotic pressure, which is isotonic, allows a consistent maintenance of body tissues. In order for a substance to be absorbed and used in the body’s metabolism, it must be transported in an isotonic state.

Isotonix dietary supplements are delivered in an isotonic solution. This means that the body has less work to do in obtaining maximum absorption. The isotonic state of the suspension allows nutrients to pass directly into the small intestine and be rapidly absorbed into the bloodstream. With nutraMetrix Isotonix products, little nutritive value is lost, making the absorption of nutrients highly efficient while delivering maximum results.

Key Ingredients Found In nutraMetrix Isotonix® Multivitamin With Iron*


Vitamin A (Beta-Carotene/Vitamin A pre-cursor) 1,576 mcg
Vitamin A is a fat-soluble vitamin. Sources of vitamin A include organ meats (such as liver and kidney), egg yolks, butter, carrot juice, squash, sweet potatoes, spinach, peaches, fortified dairy products and cod liver oil. Vitamin A is also part of a family of compounds including retinol, retinal and beta-carotene. Beta-carotene, also known as pro-vitamin A, can be converted into vitamin A when additional levels are required. All the body’s tissues need vitamin A for general growth and repair. Vitamin A helps to promote healthy night vision, support normal bone growth and support an antioxidant defense and a healthy immune system.*

Vitamin C (Ascorbic Acid) 150 mg
Vitamin C is found in peppers (sweet, green, red, hot red and green chili), citrus fruits and brussel sprouts, cauliflower, cabbage, kale, collards, mustard greens, broccoli, spinach, guava, kiwi fruit, currants and strawberries. Nuts and grains contain small amounts of vitamin C. It is important to note that cooking destroys vitamin C activity.

Vitamin C is integral in supporting a healthy immune system, promoting cardiovascular health, helping to maintain healthy cholesterol levels and providing an antioxidant defense. The body does not manufacture vitamin C on its own, nor does it store it. Therefore, vitamin C must be acquired through diet and supplementation.*

Thiamin (Vitamin B1) 2.6 mg
Thiamin plays an important role in carbohydrate metabolism and nerve function. Thiamin is required for a healthy nervous system and assists in the production of the neurotransmitter acetylcholine and gamma-aminobutyric acid (GABA). It is used in the manufacture of hydrochloric acid and, therefore, plays a part in digestion, increases energy and helps promote mental clarity.*

Pantothenic Acid (Vitamin B5) 20 mg
Pantothenic acid (B5) is the transfer agent for choline to acetylcholine, which promotes proper neurotransmitter activity in the brain. Pantothenic acid is also known as the anti-stress vitamin because it detoxifies brain tissue, helps relieve physical and emotional stress and plays a very important role in the secretion of hormones.*

Niacin (Vitamin B3) 40 mg
Niacin is a water-soluble vitamin necessary for many aspects of health, growth and reproduction. It is part of the vitamin B complex. Niacin supports the functioning of the digestive system, skin and nerves. It is also important for the conversion of food to energy. Niacin (also known as vitamin B-3) is found in dairy products, poultry, fish, lean meats, nuts and eggs as well as legumes and enriched breads and cereals.*

Vitamin B12 (Cyanocobalamin) 75 mcg
Vitamin B12 is naturally found in meats, liver, beef, pork, eggs, whole milk, cheese, whole wheat bread and fish. Vitamin B12 can only be found in animal products, with small amounts derived from fermented soy products such as miso and tempeh, and peanuts. It is essential that vegetarians consume a vitamin B12 supplement to maintain optimal health. Vitamin B12, when ingested, is stored in the liver and other tissues for later use. The synthetic form of vitamin B12, cyanocobalamin, is not derived from either plants or animals and is intrinsic in the maintenance of normal functioning body cells, especially those of the nervous system (protecting the sheaths of nerve cells), bone marrow and intestinal tract. These tissues are the first to exhibit signs of vitamin B12 depletion. Vitamin B12 itself is responsible for maintaining optimum energy levels as it plays a vital role in the Krebs energy cycle. It is also a great anti-aging ingredient and helps increase concentration.*

Folate [as (6S)-5-methyltetrahydrofolic acid, glucosamine salt, Quatrefolic®] 216 mcg
Folic acid is mainly found in fruits and vegetables. Dark, leafy greens, oranges, orange juice, beans and peas are the best sources as well as Brewer's yeast, which supplies additional B-vitamins. Folic acid plays a key role by boosting the benefits of vitamin B12 supplementation. These two B-vitamins join forces and work together in maintaining normal red blood cells. Folic acid assists in the normal utilization of amino acids and proteins, as well as supporting the construction of the material for DNA and RNA synthesis. Scientific studies have found that when working in tandem with folic acid, B12 is capable of promoting a healthy cardiovascular and nervous system.*

Riboflavin 5-Phosphate (Vitamin B2) 3 mg
Vitamin B2 is found in liver, dairy products, dark green vegetables and some types of seafood. Vitamin B2 serves as a co-enzyme, working with other B vitamins. It promotes healthy blood and supports both the nervous system and normal human growth. It supports healthy skin, nails, hair growth and helps maintain a healthy thyroid. Vitamin B2 plays a crucial role in turning food into energy as a part of the electron transport chain, driving cellular energy on the micro-level. Vitamin B2 aids in the breakdown of fats while functioning as a cofactor or helper in activating B6 and folic acid. Vitamin B2 is water-soluble and cannot be stored by the body except in insignificant amounts; thus, it must be replenished daily. Under some conditions, vitamin B2 can act as an antioxidant. The riboflavin coenzymes are also important for the transformation of vitamin B6 and folic acid into their active forms and for the conversion of tryptophan into niacin.*

Pyridoxine HCl (Vitamin B6) 4 mg
Poultry, fish, whole grains and bananas are the main dietary sources of vitamin B6. Vitamin B6 is a co-factor required for protein and amino acid metabolism and helps maintain proper fluid balance. It also assists in the maintenance of healthy red and white blood cells. Vitamin B6 is required for hemoglobin synthesis. It is involved in the synthesis of neurotransmitters in brain and peripheral nerve cells, it has been recommended as a nutrient to enhance mental function, specifically mood, and it supports normal nerve conduction. Some athletic supplements include vitamin B6 because it promotes the conversion of glycogen to glucose, for energy in muscle tissue. Vitamin B6, when taken with folic acid, has been shown to help maintain normal plasma levels of homocysteine, which promotes optimal cardiovascular health. Vitamin B6 should be administered as a part of a complex of other B vitamins for best results.*

Boron: 300 mcg

Boron is a mineral found at high levels in plant foods such as dried fruits, nuts, dark green leafy vegetables, applesauce, grape juice and cooked dried beans and peas. Boron is found in most  tissues, but mainly in the bone, spleen and thyroid. Boron functions in bone metabolism and participates in hormone metabolism.

Boron promotes healthy bones. It also helps retain adequate amounts of calcium and magnesium. Boron is an essential cofactor for the converting vitamin D to its active form. It enhances the maintenance of healthy cell membranes, proper mental functioning and alertness, and supports normal serum estrogen levels and ionized calcium.* 

Vitamin D3 (Cholecalciferol) 25 mcg
Regular sunlight exposure is the main way that most humans get their vitamin D. Food sources of vitamin D are vitamin D-fortified milk (100 IU per cup), cod liver oil, and fatty fish such as salmon. Small amounts are found in egg yolks and liver. Vitamin D promotes the absorption of calcium and phosphorus and supports the production of several proteins involved in calcium absorption and storage. Vitamin D works with calcium to promote hard, strong bones. It works to promote active transport of calcium out of the osteoblasts into the extra-cellular fluid and in the kidneys, promotes calcium and phosphate uptake by renal tubules. Vitamin D also promotes the normal absorption of dietary calcium and phosphate uptake by the intestinal epithelium. It promotes healthy growth and repair of tissues, and supports overall skin health.*

Vitamin E (d-alpha-Tocopherol Succinate) 45 mg
The most valuable sources of dietary vitamin E include vegetable oils, margarine, nuts, seeds, avocados and wheat germ. Safflower oil contains large amounts of vitamin E (about two thirds of the RDA in ¼ cup) and there are trace amounts in corn oil and soybean oil. Vitamin E is actually a family of related compounds called tocopherols and tocotrienols. Vitamin E is available in a natural or synthetic form. In most cases, the natural and synthetic forms are identical except the natural form of vitamin E is better absorbed and retained in the body. The natural form of alpha-tocopherol is known as "d-alpha tocopherol." (The natural form is found in Isotonix® Multivitamin.) The synthetic "dl-" form is the most common form found in dietary supplements. For those individuals watching their dietary fat consumption, which is relatively common in the world of dieting, vitamin E intake is likely to be low, due to a reduced intake of foods with high fat content.*

The main health benefit of supplemental vitamin E comes from its immune-boosting antioxidant activity. It also supports normal healing and is known to promote cardiovascular health. Vitamin E is one of the most powerful fat-soluble antioxidants in the body. In turn, vitamin E protects cell membranes from free radical damage.*

d-Calcium Pantothenate 20 mg
Calcium is found in milk, cheese, yogurt, corn tortillas, Chinese cabbage (Napa), kale and broccoli. Calcium is an essential mineral with a wide range of biological roles. Calcium exists in bone primarily in the form of hydroxyapatite (Ca10 (PO4)6 (OH) 2). Hydroxyapatite comprises approximately 40 percent of the weight of bone. The skeleton has an obvious structural requisite for calcium. The skeleton also acts as a storehouse for calcium. Apart from being a major constituent of bones and teeth, calcium promotes normal muscle contraction, nerve conduction, cardiovascular health, the production of energy and helps maintain a healthy immune system.*

A sufficient daily calcium intake is necessary for maintaining bone density and maintaining healthy teeth and bones. Calcium has been shown to reduce the symptoms of PMS in women. When the body does not obtain enough calcium each day, it draws calcium from the bones causing them to thin, leading to osteoporosis. Osteoporosis is the age-related thinning of the bones, which can lead to a higher risk of broken hips, ribs, pelvis and other weakened bones. This is in addition to stooped posture associated with advanced age, which is caused by an accumulation of small fractures in the vertebrae.*

The PTH (parathyroid hormone) regulates the amount of calcium in the blood. High levels of calcium in the body have been associated with cardiovascular health in postmenopausal women and maintaining normal cholesterol levels. Low levels of calcium have been associated with reduced bone mass and osteoporosis.*

Chromium (Nicotinate) 120 mcg
Chromium is found naturally in some cereals, meats, poultry, brewer’s yeast, broccoli, prunes mushrooms, fish and beer. Chromium is an essential trace mineral that promotes normal glucose metabolism and regulation of insulin levels, and helps the body maintain healthy blood levels of cholesterol and other fats. Chromium combines to form something in the body called glucose tolerance factor, or GTF, which promotes normal insulin activity in regulating blood sugar levels. Chromium has been shown to help reduce overall body fat, control hunger and suppress appetite. Many people in the weight-loss industry view chromium as an integral mineral in weight maintenance. Chromium may also contribute to an increase in lean body and muscle mass.*

Copper (Gluconate) 0.1 mg
The richest sources of dietary copper derive from organ meats, seafood, nuts, seeds, wheat bran cereal, whole grain products and cocoa products. Copper may have some antioxidant properties and acts as a component of enzymes in iron metabolism. It is an essential trace mineral. Copper is needed in normal infant development, iron transport, bone strength, cholesterol metabolism, myocardial contractility, glucose metabolism, brain development and immune function.*

Iodine (Potassium Iodide) 150 mg
Iodine is found in most seafood and in iodized salt. It is a necessary component of thyroid hormones and helps regulate and maintain a properly functioning metabolism.*

Magnesium (Carbonate) 25 mg
Foods rich in magnesium include unpolished grains, nuts and green vegetables. Green leafy vegetables are potent sources of magnesium because of their chlorophyll content. Meats, starches and milk are less rich sources of magnesium. Refined and processed foods are generally quite low in magnesium. The average daily magnesium intake in the U.S. for males nine years and older is estimated to be about 323 milligrams; for females nine years and older, it is estimated to be around 228 milligrams.

Magnesium is a component of the mineralized part of bone and is necessary for the metabolism of potassium and calcium in adults. It helps maintain normal levels of potassium, phosphorus, calcium, adrenaline and insulin. It is also important for the mobilization of calcium, transporting it inside the cell for further utilization. It plays a key role in the functioning of muscle and nervous tissue. Magnesium is necessary for the synthesis of all proteins, nucleic acids, nucleotides, cyclic adenosine monophosphate, lipids and carbohydrates.*

Magnesium is required for release of energy and it promotes the normal regulation of body temperature and proper nerve function, it helps the body handle stress, and it promotes a healthy metabolism. Magnesium works together with calcium to promote the normal regulation of the heart and blood pressure. Importantly, magnesium is also required by the body to build healthy bones and teeth, and promotes proper muscle development. It works together with calcium and vitamin D to help keep bones strong. Magnesium also promotes cardiovascular health by supporting normal platelet activity and helping to maintain normal cholesterol levels.*

Manganese (Gluconate) 2 mg
Manganese is a mineral found in large quantities in both plant and animal matter. The most valuable dietary sources of manganese include whole grains, nuts, leafy vegetables and teas. Manganese is concentrated in the bran of grains, which is often removed during processing. There are several forms of supplementary manganese including manganese gluconate, manganese sulfate, manganese ascorbate, and manganese amino acid chelates.

Only trace amounts of this element can be found in human tissue. Manganese is predominantly stored in the bones, liver, kidney and pancreas. It supports the normal formation of connective tissue, bones, blood-clotting factors and sex hormones. It promotes normal fat and carbohydrate metabolism, calcium absorption and blood sugar regulation. Manganese also promotes normal brain and nerve function.*

Potassium (Bicarbonate) 108 mg
Foods rich in potassium include fresh vegetables and fruits such as bananas, oranges, cantaloupe, avocado, raw spinach, cabbage and celery. Potassium is an essential macromineral that helps to keep fluid balance. It also plays a role in a wide variety of biochemical and physiological processes. Among other things, it supports normal nerve impulses, cardiac, skeletal and smooth muscle contractions, energy production, synthesis of nucleic acids, and helps maintain intracellular tonicity and normal blood pressure. Potassium promotes normal muscle relaxation and insulin release. It also promotes glycogen and protein synthesis. Potassium is an electrolyte that promotes proper heartbeat. Potassium is important in releasing energy from protein, fat, and carbohydrates during metabolism.*

Potassium also helps regulate water balance and assists recuperative powers. Potassium supports the normal elimination of wastes. Potassium promotes normal healing and generally contributes to a sense of well-being. Potassium is stored in the muscles.*

Selenium (Amino Acid Chelate) 55 mcg
The best dietary sources of selenium include nuts, unrefined grains, brown rice, wheat germ, and seafood. In the body, selenium functions as part of an antioxidant enzyme called glutathione peroxidase as well as promoting normal growth and proper usage of iodine in thyroid functioning. Selenium also supports the antioxidant effect of vitamin E and is often added to vitamin E supplements. As part of the antioxidant, glutathione peroxidase, selenium plays a direct role in the body’s ability to protect cells from damage by free radicals.*

Zinc (Lactate) 7.5 mg
Zinc is largely found in fortified cereals, red meats, eggs, poultry and certain seafood, including oysters. It is a component of multiple enzymes and proteins. It is also involved in the regulation of gene expression. Zinc is an essential trace mineral that has functions in approximately 300 different enzyme reactions. Thus, zinc plays a part in almost all biochemical pathways and physiological processes. More than 90 percent of the body’s zinc is stored in the bones and muscles, but zinc is also found in virtually all body tissues. It has been claimed that zinc supports normal healing and the immune system, promotes a healthy prostate gland and supports healthy sperm quality. Because zinc is involved in such a great number of enzymatic processes it has been found to support a large range of functions including digestion, energy production, growth, cellular repair, collagen synthesis, bone strength, cognitive function and carbohydrate metabolism.*

Iron Phosphate† (SunActive Fe™)‡ 15 mg
Iron is mainly found in citrus fruits, tomatoes, beans, peas, fortified bread and grain products such as cereal (non-heme iron sources). Beef, liver, organ meats and poultry comprise the heme iron sources. The heme iron sources are more absorbable than the non-heme type of iron. Iron is an essential mineral. It is a component of hemoglobin, the protein that carries oxygen in the blood, and myoglobin, another protein that carries oxygen in muscle tissue. Iron is required in red blood cell formation.*

Iron plays a part in many imperative biochemical pathways and enzyme systems including those involved with energy metabolism, neurotransmitter production (serotonin and dopamine), collagen formation and immune system function. Young children, adult men and elderly women probably do not require supplemental iron in their diets and should consult their physician before taking iron supplements (due to the risk of excessive iron). Iron has been found to promote normal oxygen transport, thus improving exercise capacity, stimulate the immune system, increase energy levels and promote normal production of neurotransmitters and collagen.

†Found only in Isotonix Multivitamin with Iron

Biotin (Vitamin B7) 300 mcg
Biotin can be found in food sources, such as egg yolks, peanuts, beef liver, milk (10 mcg/cup), cereals, almonds and Brewer’s yeast. Biotin is used in healthy cell growth, the production of fatty acids, metabolism of fats and amino acids. It plays a role in the Citric acid cycle, which is the process in which biochemical energy is generated during aerobic respiration. Biotin not only assists in various metabolic chemical conversions but also helps to transfer carbon dioxide. Biotin is also helpful in maintaining a steady blood sugar level. Biotin is often recommended for strengthening hair and nails.

Frequently Asked Questions*


Why is taking a vitamin supplement important?
A vitamin may be broadly defined as a substance that is essential for the maintenance of normal metabolic function, but which is not produced in the body and therefore must be consumed from a source outside the body. They are necessary elements in the process of converting food to energy and in the growth and repair of body tissue. Reduction of vitamin levels over extended periods can result in vitamin deficiency. These shortages may lead to symptoms which can include loss of appetite, loss of body weight, increased irri

Why is there vitamin D3 in Calcium Plus and nutraMetrix Isotonix Multivitamin?
Vitamin D3 has been added to the Calcium Plus and the nutraMetrix Isotonix Multivitamin to facilitate the uptake of calcium. Vitamin D3 is initially activated further in the skin in the presence of sunlight and then it is activated further in the kidney and liver. Vitamin D3 is a hormone that can stimulate the production of calcium-binding proteins, which aid in transporting this essential mineral through cells. The 1,2,5-dihydroxy-vitamin D3 is then transported to critical sites in the body to facilitate calcium uptake. The intestine and bone cells are two of these critical sites. There are groups of people who are not out in the sun for significant lengths of time. Certain racial groups have significant problems in the higher latitudes, especially during the winter, in producing substantial amounts of vitamin D3 and subsequently taking up enough calcium. Even with intense phototherapy for those people requiring significant calcium nutrition, the blood levels of 1,25-OH-vitamin D3 are highly regulated.
