Betaine HCL, or betaine hydrochloride, is not an essential nutrient, but it helps in absorption of proteins, vitamin B12, iron and calcium and helps in the digestive tract with the protein and fat breaking up abilities. It is a supplemental source of hydrochloric acid, with a low pH level. Besides the obvious use against indigestion and heartburn, other uses have been proclaimed for betaine HCL, such as lowering the homocysteine level, helping with thyroid conditions and others. With progressing age, hydrochloric acid and digestive enzymes may decrease, with a poor digestion as a result. With betaine HCL, when taken at the beginning of a meal, proper digestion can be accomplished. Betaine HCL is most commonly provided with the addition of pepsin, a digestive enzyme.

Biotin is required for the fatty acids and glucose formation so that essential energy is produced. Biotin also assists in the metabolism of fats, proteins and carbohydrates. Biotin is available in food naturally and the dietary sources of biotin comprise of brewer’s yeast, cauliflower, bananas, egg yolks, salmon, liver, sardines, mushrooms and legumes. The deficiency of biotin is uncommon. The other possibilities for having biotin as deficiency is genetic biotin deficiency, surgical stomach removal, excessive consumption of alcohol and infant dermatitis. Biotin deficiency leads to hair loss, skin rash, heart problems and high cholesterol. Biotin supplements are effective for eczema, acne, diaper rash, brittle nails and hair loss. People having a history of seizures should avoid using biotin. This is a B vitamin that helps in converting food to energy. It is mandatory that minimum 30 mg is taken daily as there are adequate health benefits. Normal biotin intake strengthens fingernails and also controls blood sugar levels.

Choline Bitartrate , or choline for short, is an essential nutrient involved in many bodily actions such as the structure and function of cells and metabolic functions.

Chromium Picolinate is a combination of chromium and picolinate acid. Combined with exercise, it is commonly used to lose weight through reducing appetite, increasing metabolism rate and melting fats. This, however, has not been proved clinically. It is also believed to increase energy, life span, prevent acne and improve a person’s mood. Being considered a natural alternative to steroids, it is recommended to athletes. Chromium is found in fish, poultry, whole-grains, cheese and meat. It helps in the proper working of cells by improving the efficiency of insulin. Picolinate acid helps in the proper absorption of chromium. A combination of chromium picolinate and other supplements may be risky, hence professional advice should be sought before using it. Pregnant or nursing women should also be careful.

Coenzyme Q10- The vitamin-like Coenzyme Q10 or (CoQ10) is a fat soluble substance, found in all human cells. It acts as an antioxidant thus helping the body to get rid of free radicals and facilitating biochemical reactions that produce energy in the body cells. It is found mainly in the mitochondria where the cells make energy. Since mitochondria are found in abundance in the heart and liver cells, these cells naturally contain CoQ10 too. Needless to say, those who suffer from heart disease are the one who have relatively low CoQ10 too, as the heart cannot function to its full capacity if CoQ10 is not adequately present. CoQ10 deficiency may also give rise to periodontal disease though there isn’t enough evidence to prove so. However, it has been found that those suffering from this disease have relatively less CoQ10.

DL-Methionine , an essential amino acid that helps the body in the detoxification process. Deficiencies in DL-Methionine may also result in a destructive breakdown and metabolism of protein.

Inositol is a carbocyclic polyol and a former member of the Vitamin B complex, listed as the Vitamin B8. Its most widely observed naturally occurring form is myo-inositol, which is found in many foods, such as high bran cereals, nuts beans, but also oranges and cantaloupe melons. Biological processes which are affected by inositol include the insulin signal transduction, nerve guidance in correlation with Epsin, cell membrane potential maintenance, serotonin activity modulation, cytoskeleton assembly, gene expression and breakdown of fats as well as reduction of blood cholesterol. Several psychiatric conditions can be treated with inositol, including obsessive compulsive disorder, clinical depression, panic disorder, bulimia and others. Due to all the positive influences, Vitamin B8 is a popular body building supplement; in particular the activity pertaining to the lipid metabolism is of essence.

L-Carnitine , a naturally occurring non-essential amino acid which boosts its own production when combined with Vitamin C. L-carnitine transports fatty acids like triglycerides into the mitochondria and converts it into energy. Its antioxidant properties are believed to affect the heart muscles positively. L-cartinine deficiency is a rare case. However, fatigue, muscle-cramps and pre-mature aging are some of its deficiency signs. L-carnitine is highly found in dairy products and red meat. In foods like legumes, nuts, grains, fresh fruits, vegetables and cereals although the level of L-caritine is not high, it promotes production. L-carnitine is not known to cause any toxic effect, but an overdose of carnitine i.e. 1000mg daily can cause diarrhea, stomach cramps, nausea and vomiting. Research prove that adding L-carnitine to our daily diet increases metabolism promotes weight loss and maintains a healthy level of blood glucose.

Vitamin B12, also known as cobalamin, which is naturally found in foods such as fish, milk and milk products, eggs, meat and poultry. Vitamin B12 is important for good health, necessary for the proper digestion and absorption of foods and for normal metabolism of carbohydrates, and fat. It helps maintain healthy nerve cells and red blood cells and is needed to make DNA. Vitamin B12 is bound to the protein in food. Hydrochloric acid in the stomach releases B12 from protein during digestion. Unlike other water-soluble nutrients, vitamin B12 is stored in the liver, kidney, and other body tissues. It can take several years before signs of the deficiency appear due to poor dietary intake. Vitamin B12 functions as a "methyl donor." A methyl donor is a compound that carries and donates methyl groups to other molecules, including cell membrane components and neurotransmitters. As a methyl donor vitamin B12 is involved in homocysteine metabolism and plays a critical role in proper energy metabolism, immune function, and nerve function. Therefore, vitamin B12 is clearly an added benefit for anyone wanting to lose weight, as without it, metabolism is not at its peak potential.
