Isotonix® Prenatal Multivitamin

While there are plenty of supplements for pregnant women available, Isotonix Prenatal Activated Multivitamin is the only prenatal multivitamin delivering what expectant mothers need utilizing the Isotonix Delivery System.

Isotonix Prenatal Activated Multivitamin delivers vitamins and minerals crucial for a healthy pregnancy in their active forms quicker than other prenatal supplements. This allows the nutrients to be delivered faster, easier and more effectively than any other prenatal multivitamin, as traditional supplements for pregnant women take more time and effort to transform nutrients into ways the body can utilize them.

Not only does our prenatal multivitamin formula provide activated nutrients and the Recommended Daily Allowance of key vitamins and nutrients, it utilizes the revolutionary Isotonix Delivery System. All of this means that our supplement for pregnant women gives expectant mothers the vitamins they need to have a healthy - and happy - pregnancy.


Beta-Carotene (Vitamin A Precursor) (4,000 IU)
Optimal vitamin A intake is advisable during the pre-conception period before pregnancy. Adequate amounts of vitamin A help to promote the health of the baby by promoting normal growth and development of the embryo and fetus, and supporting genes that determine the sequential development of organs in embryonic development. Beta-carotene is a nutrient from plants that the body converts into vitamin A.

Vitamin B1 (3 mg)
Vitamin B1 is a water-soluble vitamin that supports the body’s ability to process carbohydrates, fat, and protein. Every cell of the body utilizes B1 to support the formation of adenosine triphosphate (ATP), the fuel the body uses to function. Nerve cells require vitamin B1 in order to function normally. Since energy requirements and production increase in pregnancy, the RDAs for these vitamins also increase.

Vitamin B2 (3 mg)
Vitamin B2 is a water-soluble vitamin that promotes the body’s ability to process amino acids and fats, activate vitamin B6 and folic acid, and support the normal conversion of carbohydrates into adenosine triphosphate (ATP), the fuel the body uses to function. Vitamin B2 promotes energy production and since energy production increases in pregnancy, the RDAs for these vitamins also increase.

Niacin (20 mg)
Niacin promotes normal energy production. Vitamin B3 works with vitamin B1 and vitamin B2 to support the release of energy from carbohydrates. Since energy production increases in pregnancy, the RDAs for these vitamins also increase.

Pantothenic Acid (Vitamin B5) (10 mg)
Pantothenic acid (vitamin B5) is a water-soluble vitamin involved in the Kreb’s cycle of energy production and promotes the normal production of the neurotransmitter acetylcholine. When the nerve impulse originating in the brain arrives at the nerve ending, it releases a chemical called acetylcholine and assists in the neurodevelopment of the baby. Pantothenic acid works together with vitamin B1, vitamin B2, and vitamin B3 to support the production of adenosine triphosphate (ATP), the fuel our body uses to function. Vitamin B5 also supports normal producing, transporting, and releasing of energy from fats. It helps to regulate your body's adrenal activity and antibody production. If you're pregnant and don't get enough B5, your baby's growth may be slowed.

Pyridoxal-5-Phosphate (Vitamin B6) (4 mg)
Vitamin B6 is the master vitamin for processing amino acids — the building blocks of all proteins and some hormones. Vitamin B6 supports the production and breakdown of many amino acids and also promotes the production of the hormones serotonin, melatonin, and dopamine, which is vital to your fetus's developing brain and nervous system.

Methylcobalamin (Vitamin B12) (12 mcg)

Methylcobalamin is one of the naturally-occurring forms of vitamin B12 found in the human body. The liver must convert cyanocobalamin, the form of B12 most commonly used in supplements, into methylcobalamin, before it can be properly utilized by the body; methylcobalamin is more effective than non-active forms of vitamin B12. Methylcobalamin also promotes the normal formation of SAMe (S-adenosylmethionine), a nutrient that has powerful mood-elevating properties.


When consumed during pregnancy, vitamin B12 promotes the health and normal nerve function of the baby.


Vitamin B12 is a bacterial product naturally found in animal products, especially organ meats, such as liver, with small amounts derived from peanuts and fermented soy products, such as miso and tempeh. 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. It supports the maintenance of cells, especially those of the nervous system, bone marrow and intestinal tract. Vitamin B12 promotes normal homocysteine metabolism (homocysteine is an amino acid that is formed within the body). Normal homocysteine levels are important for maintaining cardiovascular health. Deficiencies of the vitamins folic acid, pyridoxine (B6) or cobalamin (B12) can result in elevated levels of homocysteine. Folate and B12, in their active coenzyme form, are both necessary cofactors for the conversion of homocysteine to methionine, thus helping to maintain healthy blood levels of homocysteine.


Folic Acid (Calcium Folinate) (800 mcg)
Folic acid is mainly found in fruits and vegetables. Dark, leafy greens, oranges, orange juice, beans, peas and brewer’s yeast are the best sources. Folic acid plays a key role by boosting the benefits of 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, which is necessary for all bodily functions. Scientific studies have found that when working in tandem with folic acid, B12 is capable of promoting normal homocysteine levels. This works toward supporting a healthy cardiovascular and nervous system.*

Biotin (300 mcg)
Biotin, a water-soluble B vitamin, acts as a coenzyme in the metabolism of protein, fats and carbohydrates. Women have an increased requirement for biotin during pregnancy, and a biotin deficiency may occur in as many as 50 percent of pregnant women, and this deficiency may increase the risk of birth defects.


Vitamin C (Ascorbic acid) (120 mg)
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that has a number of biological functions. It promotes normal tissue repair and healing. Additionally, vitamin C also supports your immune system. The female body's requirement for vitamin C increases during pregnancy as this vitamin promotes the normal growth of the baby and supports building strong bones and teeth. It also supports absorption of another key nutrient during pregnancy, iron.


Vitamin D3 (Cholecalciferol) (1000 IU)
Women have an increased requirement for vitamin D during pregnancy. The main function of vitamin D is to promote the normal regulation of serum calcium concentrations. Vitamin D enhances the intestinal absorption of calcium, primarily in the duodenum and jejunum by supporting the synthesis of calcium-binding proteins to promote healthy calcium absorption and retention.


Vitamin E (D-alpha-tocopheryl acetate) (30 IU)
Vitamin E is a fat-soluble vitamin proven to be a strong antioxidant and is absorbed by the mother and transported to the fetus. It promotes structural and functional maintenance of skeletal, cardiac, and smooth muscle. It also supports the formation of red blood cells, promotes healthy cardiovascular function and enhances the immune system.


Calcium (Lactate) (300 mg)
Another important nutrient in an expectant mother’s diet is calcium. Calcium needs increase significantly during pregnancy. Healthy levels of calcium during pregnancy may help the mother maintain normal blood pressure and water balance during pregnancy. Low dietary intake of calcium is associated with increased risk of preeclampsia (pregnancy-induced hypertension, urine protein loss and swelling around the ankles). A substantial transfer of calcium occurs between the mother and the fetus throughout pregnancy, allowing the baby's bone and teeth formation. In the first six months, the mother stores up calcium in her own bones. When its skeletal growth reaches its peak in the last three months, the fetus draws on the mother's calcium storage. This is when the consumption of high calcium-containing foods, such as milk and milk products must be increased, since a calcium deficiency could harm the mother's teeth and bones.

Copper (Gluconate) (2 mg)
Copper is an essential trace element present both in the diet and in the human body. It promotes the normal absorption and utilization of iron. It is also part of the antioxidant enzyme, superoxide dismutase (SOD). Copper promotes the normal creation of adenosine triphosphate (ATP), the energy the body uses to function. Copper promotes normal infant development, red and white blood cell maturation, iron transport, bone strength, cholesterol metabolism, myocardial contractility, glucose metabolism, brain development and immune function.

Iron (20 mg)
Iron is an important mineral found in prenatal vitamins, and is responsible for helping the mother and the baby’s blood to carry oxygen. Iron deficiencies can lead to severe birth defects for the baby. As an essential mineral, iron is part of hemoglobin, the oxygen-carrying component of the blood. The demand for iron, essential for blood formation, is also significantly increased during pregnancy because the mother's blood volume increases, and the fetal red blood cells have to be developed. In order to support fetal tissue growth, blood volume and contents must grow to help feed these tissues, including red blood cells. Further, about one-third of the mother’s iron storage will be passed on to her developing baby in order to form its blood and to be stored for future use.

Magnesium (Carbonate) (200 mg)
Magnesium, an essential mineral, promotes normal bone, protein, and fatty acid formation, cell formation, activation of B vitamins, muscle relaxation, blood clotting, and formation of adenosine triphosphate (ATP; the energy the body runs on). Magnesium promotes the health of bones (64 percent of the body's magnesium is concentrated in the bones). It supports normal bone structure and plays an essential role in more than 300 cellular reactions. Magnesium may help maintain normal blood pressure and muscle comfort during pregnancy. 


Zinc (Lactate) (15 mg)
Zinc is an essential mineral that is a component of more than 300 enzymes that support normal healing, fertility in adults and growth in children, protein synthesis, cell reproduction, vision, immune function, and protection against free radicals, among other functions. Zinc supports normal growth and development during pregnancy.  


Molybdenum (Sodium molybdate) (50 mcg)
Molybdenum is an essential trace mineral that supports the proper function of certain enzyme-dependent processes, including the metabolism of iron, which is extremely important for pregnant women.

    Wonderful Product

    Comments about Isotonix® Prenatal Activated Multivitamin:

    I love Market America Isotonix products because they are not only so much easier for my body to absorb, but they taste great too! I had terrible morning sickness for the first 18 weeks of pregnancy and could hardly keep anything down, let alone take prenatal vitamins that would make me nearly throw up because my gag reflex was so strong for a while. I didn't know there was a prenatal in the isotonix, but I am so glad I discovered it. I feel assured in the fact that my body is absorbing all the nutrients in the vitamin and so is my baby. It tastes great and I have felt more energized since I added it to my OPC-3 every morning! Great Product.

    great overall

    Comments about Isotonix® Prenatal Activated Multivitamin:

    at first, i thought it tasted disgusting. i don't know what it was but i could not breathe through my nose when drinking it! now i've been taking it for several months and somehow it doesn't taste that bad anymore. to me it's not as delicious as the regular isotonix multivitamin, but i can stand it now. and i definitely think the prenatal ingredients are great - as other people have said, if i ever miss a day of taking it i feel totally different, like tired and almost kind of sick too. so i never forget anymore! i would recommend this to anyone as a go-to prenatal multivitamin.
