Boron is a trace mineral essential to human health and must be obtained from diet or supplements. This nutrient recently gained popularity after researchers found that it helps the bones use calcium. Increased boron levels in the soil have been associated with a lower risk of osteoarthritis.
Trace minerals occur in the soil, in foods, and in your body at much lower levels than the macrominerals, so they become more easily depleted.

Calcium is a critical mineral nutrient. You must include calcium in your diet because your body can’t manufacture it. Calcium is essential for the formation and maintenance of bones and teeth.
The strength of your bones depends on calcium and other minerals like silicon and magnesium that you absorb from your diet, particularly during your years of growth and development.

Glycine is a nonessential amino acid. Dietary sources of this nutrient include fish, meats, beans, and dairy products. It also comes from choline in the liver and the amino acids threonine or serine.

Phenylalanine — an essential amino acid— is readily available in most food sources, particularly high in meats and milk products, with lower levels found in oats and wheat germ. To make use of phenylalanine, your body requires vitamin B-3, vitamin B-6, vitamin C, copper, and iron.
Phenylalanine is used to form tyrosine.

Dietary sources of glutamic acid — a nonessential amino acid — are animal and vegetable proteins. This nutrient is found in high concentrations in the human brain.
Proline derives from glutamic acid. Proline is one of the main amino acids your body uses to build collagen, which makes up the tough, elastic fibers of scar tissue and is the main structural material of your body — bones, tendons, ligaments, and skin all contain collagen.

Glutathione is a not a protein-building amino acid, but a mixture of amino acid chains. Glutathione is a nutrient that forms enzymes such as glutathione peroxidase. It is essential to life.
Dietary sources abound because glutathione is present in all plant and animal cells. It is an antioxidant nutrient that helps protect you from free radicals, keeping your tissues young and vital longer.

Alanine is a nonessential amino acid, meaning that if you don’t get this nutrient from you diet, your body can manufacture it. It is an important part of human muscle and one of the few amino acids that transforms into glucose, an important sugar that your body uses as an energy source. Alanine is included in some energy and sports formulas, but is less popular as a single supplement.

Copper is a trace mineral—an essential nutrient to humans. It must be obtained through diet or supplements. This antioxidant nutrient helps your body use iron.
Copper is a zinc-balancing mineral important in many enzymes as well as in the production of hemoglobin, the molecule that transports oxygen. It also plays a role in the functioning of the prostate gland and the activity of the oil glands, helping prevent acne.

Cysteine is an important sulfur-containing nonessential amino acid important to many metabolic (biochemical) pathways. Dietary sources of this nutrient include poultry, yogurt, oats, and wheat germ, and in sulfur-containing foods such as egg yolks, garlic, onions, and broccoli.
Cysteine is a powerful antioxidant and detoxifier as a precursor (a substance that precedes another) for glutathione enzymes, which the body, and especially the liver, use for disabling destructive free radicals.
