Produced by the body, N-acetylcysteine (commonly called NAC) is a form of the amino acid cysteine. Because it enhances the production of the Enzyme glutathione, one of the body’s powerhouse antioxidants, NAC can both stave off disease and play an important role in boosting the immune system. Studies have shown that glutathione levels are often reduced in people with certain conditions related to the immune system.
The minerals zinc and copper can be purchased as single products, but there’s good reason to consider a combination product that pairs the two.
Zinc blocks the absorption and enhances the excretion of copper when taken over time. So, when zinc is recommended long term (over many months) for any condition–from arthritis to prostate problems or even Alzheimer’s–it’s important to get some copper as well. A combination product will help prevent a copper deficiency and the anemia that can develop as a result.
Vitamin D is called the sunlight vitamin because the body produces it when the sun’s ultraviolet B (UVB) rays strike the skin. It is the only vitamin the body manufactures naturally and is technically considered a hormone. Essential for building strong bones and teeth, vitamin D also helps to strengthen the immune system and may prevent some types of cancer.
A high-quality vitamin B complex supplement will provide, in one convenient pill, a full range of B vitamins, including biotin, choline, folic acid, inositol, PABA (para-aminobenzoic acid), and the six “numbered” B vitamins–vitamin B-1 (thiamin), B-2 (riboflavin), B-3 (niacin), B-5 (pantothenic acid), B-6 (pyridoxine), and B-12 (cobalamin). Combination products can simplify the process of taking individual B vitamins for a range of ailments including alcoholism, depression, diabetes, hair problems, lupus, multiple sclerosis, and stress.
This famed vision-enhancing nutrient was isolated in 1930, the first fat-soluble vitamin to be discovered. The body acquires some of its vitamin A through animal fats. The rest it synthesizes in the intestines from the beta-carotene and other carotenoids abundant in many fruits and vegetables.
Omega-6 fatty acids belong to a group of “good” fats called polyunsaturated fatty acids. Unlike such “bad” fats as cholesterol and saturated fatty acids (which contribute to the worsening of a host of ailments including heart disease and other degenerative conditions), omega-6s can actually be beneficial to your health.
Omega-6 fatty acids are one of two types of essential fatty acids (EFAs) that people need to consume to stay healthy. Omega-3s are the other. Both are considered “essential” because the body can’t produce them on its own; it can only get them through foods.
Healers have used the prickly milk thistle plant to treat liver ailments for more than 2,000 years. Somehow these early practitioners figured out that preparations of this purple-flowered member of the sunflower family could stimulate the flow of bile from the liver, improving digestion and various liver-related ills.
As its name implies, grape seed extract is derived from the small seeds (and occasionally the skins) of red grapes–the same kind that are pressed to make wine. Used extensively in Europe, grape seed extract is rich in flavonoids, phytochemicals that have antioxidant properties some consider even greater than the old standbys vitamin C and vitamin E. Antioxidants are believed to prevent and control numerous ailments by safeguarding cells against the ravages of unstable oxygen molecules called free radicals.
A source of fiber for linen fabric since ancient times, the slender flax plant (Linum usitatissimum) also boasts a long history as a healing herb. First cultivated in Europe, the plant’s brown seeds were regularly used to prepare balms for inflamed skin and healing slurries for constipation. Today, flaxseeds–also called linseeds–are best known for the therapeutic oil that is derived by pressing them. Rich in essential fatty acids, or EFAs, flaxseed oil has earned a solid reputation for treating a range of ailments, from heart disease to lupus.
Heralded for its heart-healthy actions, fish oils offer high concentrations of polyunsaturated fats called omega-3-fatty acids. While all fish contain these fats, cold-water fish–salmon, sea bass, tuna, trout, mackerel–are particularly rich sources because of their diet: plankton packed with omega-3s. Interestingly, the colder the water, the more omega-3s in the plankton. Cold-water fish also boast the most potent forms of omega-3s: the essential fatty acids known as eicosapentaenoic acid (EPA) and docosahexanoic acid (DHA). Consumed as part of a fish-filled diet or in supplement form, omega-3s have myriad healing powers.
Evening primrose oil is extracted from the evening primrose plant (Oenothera biennis), a wildflower found in North America, Europe and parts of Asia. The plant’s pale yellow flowers open in the evening–hence its common name–and its seeds bear the special fatty oil that is used in healing today.
Thought to have originated in Cayenne, French Guiana, cayenne is a spice derived from several varieties of dried hot peppers in the Capsicum species. Cayenne is a relative of the mild bell pepper used in salads and also of the fiery peppers found in chili powders and hot sauces, but it has no connection to black table pepper. Used for centuries by cooks around the world to add “heat” to traditional dishes, cayenne has gained a solid reputation both as a painkiller and digestive aid.
From its bristly stems to its blue star-shaped flowers, virtually all parts of the borage plant (Borago officinalis) have been used over the centuries for their healing properties and as a flavoring for foods. As early as the 1600s, Europeans mixed borage leaves and flowers into a wine that was renown for relieving boredom and dispelling melancholy.
Beta-carotene is probably the best known of the carotenoids, those red, orange, and yellow pigments that give color to many fruits and vegetables. The body converts beta-carotene into vitamin A, a nutrient first identified in the 1930s and now recognized as vital to the growth and development of the human body.
A succulent perennial plant belonging to the lily family, aloe vera grows wild in Madagascar and large portions of the African continent. Because of its many therapeutic uses, it is now commercially cultivated in the United States, Japan, and countries in the Caribbean and Mediterranean. Many individuals also grow aloe as a houseplant.
