Source Naturals Melatonin 1 mg - 100 Vegetarian CapsulesSource Naturals Melatonin can be used for occasional sleeplessness. Source Naturals Melatonin is a neurohormone produced in humans by the pineal gland. A favorite of travelers, Source Naturals Melatonin governs the body's circadian rhythms, helping the body ease into restful sleep. Source Naturals Melatonin is also a potent antioxidant. Source Naturals Melatonin addresses the following body systems:Antioxidant Defens Metabolism/Hormones Cognition / Nerves Immune Antioxidant DefenseFree radicals are unstable, destructive molecules with one missing, unpaired electron. In a process called oxidation, the same process that turns iron to rust, free radicals can impact cells as they steal electrons from healthy molecules, starting a cascade that ages the body and affects the body cell by cell, tissue by tissue. This process is halted with antioxidants. Antioxidants selflessly donate their electrons to stabilize free radicals and prevent their effects. Free radicals are natural by-products of mitochondrial energy generation and they are also the result of constant bombardment by pollutants, toxins, excess sunlight, unnatural foods, and electromagnetic radiation. Metabolism/HormonesAt any moment, millions of biochemical reactions are taking place in or around our nearly 100 trillion cells. To function at high levels of health, our metabolism is constantly binding molecules together and breaking them apart. In a way, our health is a function of the ease, speed, and coordination of these myriad reactions, processes named methylation, acetylation, phosphorylation, and sulfation. Hormones are messengers that tell the body to begin its various physiological activities, such as growth or sexual development. Hormones are produced in our glands and are often triggered by the brain. They are part of the intricate mechanism that makes us humans with unique personalities. Cognition / NervesThe human brain is the most complex structure known to man; much of how it functions and enables us to think, feel, contemplate abstract concepts, plan our future, and control many bodily processes is yet to be discovered. The function of the brain and nervous system is based on the unique structure of nerve cells (also called neurons), which take in and send out messages in the form of electrical impulses running through the phospholipids and minerals of the cell membranes. Although it is only two percent of our body weight, the brain consumes 20 percent of our energy. Neurotransmitters, brain chemicals that pass messages from one neuron to another, must be produced in adequate quantities to support mood, intelligence, concentration, assertiveness and calmness. This creates a tremendous need for nutritional fuel and energy. Brain functioning can be significantly improved by the right quantity and quality of nutrients. ImmuneDuring the Plague of the 14th century, one-third of the population of Europe died. The question is: why did the others live, even though they were also exposed to the Yersinia pestis bacteria? The answer may be the strength and responsiveness of their immune systems. The immune system is like an intelligent second brain with the unique ability to identify foreign compounds and to quickly produce the specific defenses needed to combat harmful invaders and protect us. The immune system uses a wide variety of cells and biochemicals located primarily in the blood stream and the gastrointestinal tract, such as T-cells, B-cells, macrophages, and Natural Killer cells. We can significantly strengthen and improve the functionality of the immune system through nutrition, supplements and lifestyle modifications.Source Naturals OverviewLeaders of the Wellness RevolutionSource Naturals was created in 1982 by C.E.O Ira Goldberg to support each individual's potential to enjoy optimal health. At that time, the kind of nutritional formulations he envisioned â€“ for the maintenance of well- being and the enhancement of life â€“ simply didn't exist. The idea of combining many nutrients, herbs and nutraceuticals in one formulation, though common today, was then a rarity. Source Naturals pioneered the concept with Wellness Formula, now the industry's #1 immune support product.Source Naturals subsequently introduced numerous award-winning formulas, recognized for their excellence in independent surveys and nutritional analyses. In addition to Wellness, these award-winners include Life Force Multiple, Mega-Kid Multiple, Inflama-Rest, the Skin Eternal line, Higher Mind, Essential Enzymes, Male Response, and more.Source Naturals' comprehensive Bio-Aligned Formulas help bring the power of alignment to your body.
