Zinc is an important trace mineral. This element is second only to iron in its concentration in the body.

Zinc is a mineral that is essential for a healthy immune system, production of certain hormones, wound healing, bone formation, and clear skin. It is required in very small amounts, and is thus known as a trace mineral.

Zinc formulations have been used since Ancient Egyptian times to enhance wound healing, although the usefulness of this approach is only partially confirmed by clinical data of today. Zinc is necessary for the functioning of over 300 different enzymes and plays a vital role in an enormous number of biological processes. Zinc is a cofactor for the antioxidant enzyme superoxide dismutase (SOD) and is in a number of enzymatic reactions involved in carbohydrate and protein metabolism. Its immunologic activities include regulation of T lymphocytes, CD4, natural killer cells, and interleukin II. In addition, zinc has been claimed to possess antiviral activity. It has been shown to play a role in wound healing, especially following burns or surgical incisions. Zinc is necessary for the maturation of sperm and normal fetal development. It is involved in sensory perception (taste, smell, and vision) and controls the release of stored vitamin A from the liver. Within the endocrine system, zinc has been shown to regulate insulin activity and promote the conversion thyroid hormones thyroxine to triiodothyronine. Based on available scientific evidence, zinc may be efficacious in the treatment of (childhood) malnutrition, acne vulgaris, peptic ulcers, leg ulcers, infertility, Wilson's disease, herpes, and taste or smell disorders. Zinc has also gained popularity for its use in prevention of the common cold. The role for zinc is controversial in some cases, as the results of published studies provide either contradictory information, and/or the methodological quality of the studies do not allow for a confident conclusion regarding the role of zinc in those diseases.

Vitamin B12 is an essential water soluble vitamin that is commonly found in a variety of foods such as fish, shellfish, meats, and dairy products. Vitamin B12 is frequently used in combination with other B vitamins in a vitamin B complex formulation. It helps maintain healthy nerve cells and red blood cells, and is also needed to make DNA, the genetic material in all cells. Vitamin B12 is bound to the protein in food. Hydrochloric acid in the stomach releases B12 from protein during digestion. Once released, B12 combines with a substance called intrinsic factor (IF) before it is absorbed into the bloodstream. The human body stores several years' worth of vitamin B12, so nutritional deficiency of this vitamin is extremely rare. Elderly are the most at risk. However, deficiency can result from being unable to use vitamin B12. Inability to absorb vitamin B12 from the intestinal tract can be caused by a disease known as pernicious anemia. Additionally, strict vegetarians or vegans who are not taking in proper amounts of B12 are also prone to a deficiency state. A day's supply of vitamin B12 can be obtained by eating 1 chicken breast plus 1 hard-boiled egg plus 1 cup plain low-fat yogurt, or 1 cup milk plus 1 cup raisin bran.

A cobalt-containing, B complex vitamin. Cyanocobalamin and hydroxocobalamin are synthetic forms of vitamin B 12 . Hydroxocobalamin: Antidote for cyanide poisoning.

Vitamin B12 is a water-soluble vitamin. Water-soluble vitamins dissolve in water.

Cobalamin, also known as B 12, is a member of the water-soluble family of B vitamins. It is a key factor in the body''s proper use of iron and formation of red blood cells.

Amino acid derivative; naturally occurring substance required in mammalian energy metabolism.

Carnitine is an amino acid that is essential for babies and nonessential for others. In this context, essential means it must be obtained in the diet.

The main function of L-carnitine is to transfer long-chain fatty acids in the form of their acyl-carnitine esters across the inner mitochondrial membrane before beta-oxidation. In humans, it is synthesized in the liver, kidney, and brain and actively transported to other areas of the body. For example, 98% of the total body L-carnitine is confined to the skeletal and cardiac muscle at concentrations approximately 70 times higher than in the blood serum. Supplementation may be necessary in rare cases of primary carnitine deficiency, which may be caused by a defect in carnitine biosynthesis, a defect in carnitine active transport into tissue, or a defect in renal (kidney) conservation of carnitine. Known conditions of secondary deficiency of carnitine (insufficiency), in which L-carnitine is effective, include chronic stable angina and intermittent claudication characterized by distinct tissue hypoxia (low oxygen levels). Another condition that may benefit from carnitine supplementation is decreased sperm motility. Although use in preterm infants suggests carnitine supplementation may aid in maintaining or increasing plasma carnitine levels and possibly weight gain, carnitine is not routinely added to preterm total parenteral nutrition (TPN). However, soy-based infant formulas are fortified with carnitine to levels found in breast milk. In 1986, the U.S. Food and Drug Administration (FDA) approved L-carnitine for use in primary carnitine deficiency. D-carnitine or DL-carnitine may cause secondary L-carnitine deficiency and should not be used.

Antineoplastons are a group of naturally occurring peptide fractions, which were observed by Stanislaw Burzynski, MD, PhD in the late 1970s to be absent in the urine of cancer patients. It was hypothesized that these substances may have anti-tumor properties. In the 1980s, Burzynski identified chemical structures for several of these antineoplastons, and developed a process to prepare them synthetically. Antineoplaston A10, identified as 3-phenylacetylamino-2,6-piperidinedione, was the first to be synthesized. The use of antineoplastons in the treatment of various cancer types has been studied in the laboratory and in animals, and in limited preliminary human research. In 1991, the Cancer Therapy Evaluation Program of the National Cancer Institute (NCI) examined records of seven patients with brain tumors treated at the Burzynski Clinic in Texas. Based on their findings, the NCI sponsored a brain tumor clinical trial. However, due to difficulty recruiting patients, and a disagreement over study design, this research was canceled. The results in nine patients included prior to cancellation were reported, but were not conclusive. In 1997, Dr. Burzynski had legal troubles for permitting antineoplastons to be shipped out of Texas. There is a lack of sufficient evidence from randomized, controlled trials in support of antineoplastons as a cancer treatment, and antineoplastons are not FDA approved therapies. Antineoplastons are not widely available in the United States, and safety and efficacy are not proven. Multiple studies of antineoplastons in various cancers have been sponsored by the Burzynski Research Institute. In recent years, antineoplastons have also been suggested as treatment for other conditions such as Parkinson's disease, sickle cell anemia, and thalassemia.
