L-arginine is an amino acid that has numerous functions in the body. It helps the body get rid of ammonia (a waste product), is used to make compounds in the body such creatine, L-glutamate, and L-proline, and can be converted to glucose and glycogen if needed. L-arginine is used to make the nitric oxide, a compound in the body that relaxes blood vessels. Preliminary studies have found that L-arginine may help with conditions that improve when blood vessels are relaxed (called vasodilation), such as atherosclerosis, erectile dysfunction, and intermittent claudication. L-arginine is also involved in protein formation. In larger amounts, L-arginine stimulates the release of hormones growth hormone and prolactin.

L-Carnitine assists in the transport of long-chained fatty acids that are burned for energy; L-Carnitine enhances the consumption of fat as a source of fuel; L-Carnitine has been shown to increase the amount of fat you burn during both anaerobic (strength training) and aerobic (cardiovascular) workouts; L-Carnitine plays an important role in mobilizing fatty deposits found in tissues of overweight individuals; L-Carnitine helps remove fats waste products (ketones) from the blood stream; Effective carnitine activity helps to discourage fatty build up in the liver, heart, and skeletal muscle; L-Carnitine has been shown to improve lean muscle strength. Maintaining muscle tissue takes four to five times more calories than maintaining fat tissue, which is important for permanent weight loss; L-Carnitine helps to stabilize blood sugar and eliminate cravings for carbohydrates.

First, you need to start taking at least 1000 mg per day of L-Carnitine to promote weight loss. Obese individuals may start with 2000 mg per day. Those with metabolic resistance, start to do well on 3000-5000 mg per day. Research has shown, that when you start to feel more energy, it is a sign that the level of carnitine, you are using, is starting to burn body fat. Increase carnitine by 500 mg per day (one capsule) until you begin to feel this increased energy level in you daily lifestyle. Your energy level will be your guide as to how effective carnitine is working in your body. The Physician's Desk Reference (PDR) lists no toxic effects from prolonged use of L-Carnitine. It is best taken before breakfast and lunch.

Licorice Root
Licorice was used historically to treat the skin and coughs. It is also used to treat constipation, bronchitis, inflammation, and arthritis. Licorice may be prescribed by health care providers to treat adrenocortical insufficiency, peptic ulcer, and chronic gastritis. Glycyrrhizin, a glycoside, makes up almost 8% of the licorice plant. These chemical compounds could have positive effects on the body. Two enzymes that break down prostaglandin E (PGE) are stopped by glycyrrhizin. Low levels of PGE are linked to problems such as stomach inflammation, colic, and ulcers. Glycyrrhizin stops the enzymes from lowering PGE levels allowing levels to increase. Increased PGE aids the production of stomach mucus which lowers the high acid levels that can lead to stomach disorders. Respiratory mucus production is also increased by glycyrrhizin. This increase helps the mucus to lose stickiness and leave the body more easily. Licorice can also rid lungs of mucus and is used to treat problems such as bronchitis and to relieve coughing and sore throats. Many cough lozenges and syrups use licorice as flavoring and as a cough suppressant.
Traditional Chinese Medicine uses licorice to treat problems from tuberculosis to diabetes. Restrained production of cortisol and anti-inflammatory effects are caused by the flavonoids and glycyrrhizin in licorice. Research has shown that licorice flavonoids can kill the bacteria that causes stomach inflammation and ulcers, called Helicobacter pylori.

Lutein is a nutrient that belongs to the carotenoid family, and is naturally present in some vegetables and fruits. In recent years, a great deal of research has shown that lutein along with another nutrient, zeaxanthin, is vital for healthy eyes. In particular, some landmark studies have shown that daily lutein intake after only a few months can increase the thickness of the eye's macula significantly. As such, people with Age-Related Macular Degeneration (or who are prone to develop it) are often advised to increase their consumption of this nutrient. In addition, lutein may also lessen the chance of getting eye cataracts.
Other less known potential benefits of lutein are:
1) Anti-cancer agent -- Utah Medical School discovered that even a small consumption of this nutrient markedly slashed the risk of developing colon cancer. Colon cancer is the number #2 cancer killer in the U.S.
2) Helping to ward off the effects of bad cholesterol, and keeping arteries clear.
3) Alleviating arthritis and osteoarthritis aches.
Many of the health benefits of lutein may be explained by the fact that it is a potent antioxidant,and, therefore, can counter free radical damage. If left unchecked, free radicals can lead to cellular damage, which has been postulated to be a leading cause of heart disease, cancers, and premature aging.
