Essential amino acids are amino acids that cannot be synthesized by the body and must be ingested from plant and animal sources. There are ten essential amino acids needed by humans plus an extra two essential amino acids needed by infants. For athletes, a large amount of essential amino acids of all types is needed to help repair, grow and maintain muscle. This iis where 3 essential amino acids come into play .These are leucine, isoleucine and valine.
Leucine, Isoleucine and Valine are Branched CHAINED essential Amino Acids(BCAA). These three amino acids account for 35% of the essential amino acids in muscle protein and 40% of the essential amino acids required by humans. Due to their importance, dietary supplementation of these amino acids has become quite common due to their beneficial effects. BCAAs help burn patients to recover faster as the amino acids in high concentration provide the material for the cells to repair themselves at a faster rate. At the same time, BCAAs help in managing diabetes
Are very popular due to their many functions in the body of an athlete. This is because unlike other amino acids, it is metabolized in muscle tissue, not in the liver thus it has a more direct effect on the muscles than other amino acids.
These functions include:

DHA is a fatty acid that is essential for many body processes and structures. Fatty acids are the building blocks that create lipids, which are important nutrients that make up 25 to 45 percent of total body energy for most of those who are living in industrialized countries. The majority of dietary fatty acids are made from dairy products, meat, margarine, and vegetable oils.
Lipids are important because they store and transport energy from one part of the body to another and they also insulate and mechanically protect certain parts of the body. Any fat that is eaten is converted by the body into fatty acids, where it is then burned for energy, stored, or synthesized into other acids which are called prostaglandins. Some fatty acids are also vital structural components of cell membranes. DHA is part of a special class of highly concentrated, long-CHAINED, polyunsaturated fatty acids called omega-3 fatty acids. Omega-3 fatty acids are looked at as one of the most fundamental molecules in the structure and activity of the membranes of all cells. They have a huge influence on the production of cellular regulatory compounds which are known as eicosanoids. They also are highly specialized in their function in neurological tissues, especially the retina of the eye. It is also very likely that omega-3s have specific and beneficial effects on the heart muscle, while they also influence the production of substances that control immune responses.
Fatty acids are short-CHAINED, medium-CHAINED, or long CHAINED. Short-chain fatty acids are water-soluble and absorbed directly from the intestine into the bloodstream. They are generally used for immediate energy and can be found most abundantly in dairy products. Long-CHAINED fatty acids are more emphasized when it comes to health concerns as they are stored in cell membranes and have a huge affect on membrane protein function. Their behavior in tissue membrane is what makes them greatly influential in health.
Besides the length of the chain, fatty acids are also described by their saturation. Saturation means how many hydrogen atoms the fatty acid carries. Fatty acids that carry as many hydrogen atoms as they can are called saturated fatty acids, while those that lose a pair of hydrogen atoms become unsaturated. This loss of hydrogen atoms creates a double bond between the two carbon atoms on either side of the missing hydrogen atoms. Those fatty acids that have one double bond are called monounsaturated fatty acids, while those with two or more double bonds are called polyunsaturated fatty acids. Most omega-3 fatty acids are highly unsaturated and have five or more double bonds.
EPA and alpha-linolenic acid are most commonly found in plant sources. DHA and EPA are made in phytoplankton, which is consumed by fish, mollusks, and crustaceans. The above reason is why these two essential fatty acids are found mainly in the aquatic food chain. LNA and EPA cannot substitute for DHA in all metabolic functions, even though DHA and EPA are more able to cover for each other in certain metabolic functions. It has been found that LNA is less effective than EPA which is less effective than DHA in enriching tissues, meaning that food sources such as vegetables and seed oils are not as good of sources than sea foods or other foods that are enriched with DHA and EPA. DHA in itself provides most of the health benefits displayed in research, to take essential oils that contain no DHA would limit the health benefits discussed above and from other sources.

Sources of Essential Fatty Acids
Essential fatty acids are found in both plant and animal sources, although primarily in plants. The EFA family is composed of two main forms, Omega-3 and Omega-6. The following explains exactly what these forms are.
OMEGA-3: The most common forms of Omega-3 are eicosapentaenioic acid (EPA), docosahexaenoic acid (DHA) and alpha-linolenic acid, which comes from plants and helps create EPA and DHA. Omega-3 is usually derived from fish oils. Dr. Roger Illingworth, associate professor of medicine and biochemistry at Oregon Health Sciences University, explains that Omega-3 fatty acids are “long-CHAINED metabolic products from linolenic acid. . . When animals consume and metabolize plants rich in linolenic acid, they produce Omega-3.” EPA and DHA are liquid and remain that way, even at room temperature. It is said that they protect fish by providing a body fat that stays fluid even in cold temperatures. OMEGA-6: The most common form of Omega-6 is is gammalinolenic acid (GLA). GLA is known to provide the following benefits, among many others:
Omega-6 is usually found in plant sources. The oils of coldwater fish such as salmon, bluefish, herring, tuna, mackerel and similar fish are known as Omega-3 fatty acids. The freshpressed oils of many raw seeds and nuts contain Omega-6 fatty acids. The most popular sources of Omega-3 and Omega-6 include:
BLACK CURRANT SEED OIL: This oil is rich in linoleic acid (44%) and provides almost twice as much gamma-linolenic acid as evening primrose oil. Black currant seed oil also is an excellent source of an Omega-3 precursor known as stearidonic acid. BORAGE OIL: This oil comes from Borago officinalis, a plant with blue flowers. It is widely recommended in Europe to strengthen the adrenal glands, alleviate symptoms of premenstrual syndrome and relieve inflammation. Besides possibly helping with heart and joint function, it may also assist the growth of nails and hair. Borage oil is also an excellent source of GLA. In The Complete Medicinal Herbal, herbalist Penelope Ody asserts that it is “helpful in some cases of menstrual irregularity, for irritable bowel syndrome, or as emergency first aid for hangovers.” SALMON OIL: This oil is high in Omega-3 essential fatty acids. These types of EFAs are known to thin the blood, prevent clotting, regulate cholesterol production and strengthen cell walls, making them less susceptible to viral and bacterial invasion. Salmon oil has a natural ability to help the body relieve inflammation. In the ground-breaking book The Omega-3 Breakthrough: The Revolutionary, Medically Proven Fish Oil Diet, professor Roger Illingworth writes that Linolenic acid is a fatty acid with 18 carbons and 3 double bonds.
It is manufactured exclusively by plants. When animals consume and metabolize plants rich in linolenic acid, they produce Omega- 3. Plankton, a minute form of marine life, is part plant and part animal. Its plant component manufactures linolenic acid. Fish eat the plankton, and the linolenic acid breaks down in their bodies in two types of Omega-3 fatty acids: EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) . . . The liquidity of EPA and DHA serves a vital function in fish, who require body fat that remains fluid even in very cold water. Fish oils, besides containing Omega-3 fatty acids, have shown to benefit those suffering from migraine headaches, arthritis, and high cholesterol levels.
FLAX: Flax is a plant said to date back as far as 5000 B.C. It has been used since approximately 5000 B.C., making it one of the oldest cultivated crops. It is exported from several countries, including Argentina, Canada, India, Russia and the United States. The flowers are usually blue, although they are sometimes white or pink. The mucilaginous seed is, of course, called flaxseed. The oil primarily provides Omega-3/linolenic acid, and provides an average of 57 percent Omega-3, 16 percent Omega-6, and 18 percent of the non-essential Omega-9. Flaxseed oil is said to contain rich amounts of beta carotene (about 4,300 IU per tablespoon) and vitamin E (about 15 IU per tablespoon). In the October 1995 issue of Let’s Live, the history and uses of flax were highlighted by herbalist Carla Cassata. She writes, . . . It’s no wonder the Cherokee Indians highly valued the flax plant. They mixed flaxseed oil with either goat or moose milk, honey and cooked pumpkin to nourish pregnant and nursing mothers, providing them with the needed nutrients for creating strong and healthy children. It was also given to people who had skin diseases, arthritis, malnutrition as well as men wishing to increase virility. They believed flax captured energies from the sun that could then be released and used in the body’s metabolic process.
This belief has merit. Flaxseed oil, rich in electrons, strongly attracts photons from sunlight. To be effective, EFAs must be combined with protein at the same meal. This flaxseed oil/protein/ sunlight combination releases energy and enhances the body’s electrical system. Also, this combination, along with vitamin E, can be beneficial for infertile couples and women suffering from premenstrual syndrome . . . Flaxseed oil, having an anti-inflammatory effect on the body, can benefit the 40 million Americans suffering from osteoarthritis and rheumatoid arthritis. To achieve optimum results, however, substances that activate the sympathetic nervous system—like refined sugar, soda, coffee, fluoride— must be eliminated. Stress must also be reduced, because it too, activates the sympathetic nervous system, promoting inflammation.
EVENING PRIMROSE: This flower is indigenous to North America, although the oil is particularly popular throughout Europe for therapeutic purposes. It is also known as night wil - low and evening star. It is an excellent source of both linolenic and linoleic acids. Both of these nutrients must be obtained from the diet, as the body cannot synthesize them. The seeds contain gamma linolenic acid. This polyunsaturated EFA helps with the production of energy and is a structural component of the brain, bone marrow, muscles and cell membranes. Evening primrose oil has also benefited those with multiple sclerosis, PMS, hyperactivity and obesity. It is estimated that it takes about 5,000 seeds to produce the oil for one 500 mg capsule.
