Isotonix® Delivery System


Isotonix - the World's Most Advanced Nutraceuticals

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 Isotonix products, little nutritive value is lost, making the absorption of nutrients highly efficient while delivering maximum results.

Key Ingredients Found In nutraMetrix® Isotonix Essentials™ Turn Down*


L-Tryptophan: 500 mg
In the body, tryptophan is converted into 5-hydroxytryptophan, which then can be converted into serotonin. The body cannot naturally produce this amino acid; therefore, it must be a part of the diet or ingested through supplementation. Tryptophan is a component of many animal and plant proteins. Food sources of tryptophan are dairy products, beef, poultry, barley, brown rice, fish, soybeans and peanuts.*

Vitamin C (Ascorbic Acid): 604 mg
Vitamin C is found in peppers (sweet, green, red, hot red and green chili), citrus fruits and brussels 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.

Potassium (Biocarbonate): 384 mg

Potassium is an electrolyte stored in the muscles. Foods rich in potassium include bananas, oranges, cantaloupe, avocado, raw spinach, cabbage and celery. Potassium is an essential macromineral that helps maintain fluid balance in the body. It also supports a wide variety of biochemical and physiological processes. Among other things, potassium supports the normal transmission of nerve impulses, contraction of cardiac, skeletal and smooth muscle, synthesis of nucleic acids, maintenance of intracellular tonicity and maintenance of normal blood pressure. In 1928, it was first suggested that high potassium intake could help maintain cardiovascular health. Potassium supports normal muscle relaxation and insulin release. It also promotes glycogen and protein synthesis. Potassium is an electrolyte that promotes normal heartbeat. Potassium supports the body’s ability to regulate water balance, recover from exercise and eliminate wastes.*

Calcium (Lactate, Carbonate, Sulfate, Citrate): 375 mg
The highest concentration of calcium is found in milk. Other foods rich in calcium include vegetables such as collard greens, Chinese cabbage, mustard greens, broccoli, bok choy and tofu. 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).

Magnesium (Carbonate, Citrate, Glycinate, Oxide): 300 mg

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

Niacin (as Niacinamide): 20 mg NE

Niacin plays an essential role as a coenzyme (NAPH/ NADPH) for about 200 enzymes which promote normal tissue respiration, synthesis of fatty acids and steroid hormones, the metabolism of carbohydrates and amino acids, and the transport of hydrogen. When niacin levels are low, the body can use L-tryptophan to manufacture the vitamin. To produce 1 mg of niacin, the body must use 60 mg of L-tryptophan, a process which can rapidly deplete L-tryptophan levels. When niacin levels are sufficient, L-tryptophan can be used for other needs such as retaining healthy levels of serotonin.*

Vitamin B6 (Pyridoxine HCl): 4 mg
Vitamin B6 promotes the normal conduction of nerve impulses, regulation of steroid hormones, catabolism of glycogen for glucose, heme synthesis, and the synthesis/metabolism of amino acids and neurotransmitters. After conversion to pyridoxal phosphate (PLP), vitamin B6 acts as a cofactor for many enzymatic reactions involving L-tryptophan, including L-tryptophan’s conversion to serotonin.*

Riboflavin (Vitamin B2): 2.9 mg
Vitamin B2 is found in liver, dairy products, dark green vegetables and some types of seafood. It serves as a coenzyme, working with other B vitamins. It promotes healthy red blood cell formation, supports the nervous system, respiration, antibody production and normal human growth. It supports healthy skin, nails, hair growth and promotes normal thyroid activity (a healthy thyroid is essential in maintaining a healthy weight, among other things). Vitamin B2 supports the body's ability to turn food into energy as a part of the electron transport chain, driving cellular energy on the micro-level. Riboflavin can be useful for pregnant or lactating women, as well as athletes due to their higher caloric needs. Vitamin B2 also promotes the normal breakdown of fats. Vitamin B2 is water-soluble and cannot be stored by the body except in insignificant amounts. It must be replenished daily.*

Manganese (Sulfate): .5 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.

Boron (Citrate): .5 mg

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 supports normal bone and hormone metabolism. Boron supports the body’s ability to build and maintain healthy bones. It also helps retain adequate amounts of calcium and magnesium to promote proper bone mineralization. Boron is an essential cofactor for the converting vitamin D to its active form. It helps maintain healthy cell membranes, supports proper mental functioning and alertness, and supports normal serum estrogen levels and ionized calcium.*

Vitamin D3 (Cholecalciferol): 12.5 mcg (500 IU)
Regular sunlight exposure is the main way that most humans get their vitamin D. Food sources of vitamin D include vitamin D-fortified milk (100 IU per cup), cod liver oil and fatty fish such as salmon, and small amounts are found in egg yolks and liver.

Vitamin A (1% as Beta Carotene): 362 mcg RAE

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. All the body’s tissues use Vitamin A for normal growth and repair.*

EXCELLENT PRODUCT!

I would occasionally awaken between 2:00-4:00AM and be unable to fall back to sleep. My friend suggested I take this product at that time but I was hesitant because I was afraid I would oversleep or feel a hangover affect that some sleep aids produce. Boy was I wrong. I always fall back to sleep and wake up feeling refreshed and ready to go!!

I also take this product during the day when I feel overwhelmed or my mind is racing due to family and career demands. It calms me down and keeps me level headed to prioritize and complete tasks. TRY THIS PRODUCT!
