Vitamin B12

Vitamin B12 is a nutrient that helps keep the body’s nerve and blood cells healthy and helps make DNA, the genetic material in all cells. Vitamin B12 deficiency causes tiredness, weakness, constipation, and megaloblastic anemia, among others. Nerve problems, such as numbness and tingling in the hands and feet, can also occur. Other symptoms of vitamin B12 deficiency include problems with balance, depression, confusion, dementia, poor memory, and soreness of the mouth or tongue.

Vitamin B12 Due to its role in energy metabolism, vitamin B12 is frequently promoted as an energy enhancer and an athletic performance and endurance booster.

Niacin (vitamin B3)

Niacin is important to the health of the digestive system, skin and nerves, according to the National Institutes of Health. Niacin is a type of B vitamin. It is water-soluble, which means it is not stored in the body. Water-soluble vitamins dissolve in water. Leftover amounts of the vitamin leave the body through the urine. Niacin has the ability to lower blood lipids (cholesterol and triglycerides).

Maca (Lepidium meyenii)

Maca is a dietary supplement derived from the processed tuberous root of Lepidium meyenii Walpers (family Brassicaceae; synonyms: L. peruvianum G. Chacon de Popovici; common names: Peruvian ginseng, maka, mace, maca-maca, maino, ayak chichira, ayuk willku, pepperweed). Maca is very nutritious, with 60–75% carbohydrates, 10–14 % protein, 8.5% fiber, and 2.2% lipids. Maca has been suggested to improve the rate of metabolism, provide strength and stamina, keeps blood sugar levels under control, improve functioning of the thyroid gland, improve muscle mass, keep cholesterol levels under control, and acts as antidepressant.

Amino acids: Arginine and ornithine

Amino acids are the building blocks for proteins, but some of them are also needed to make hormones, including growth hormone. Ornithine and arginine are important for synthesizing human growth hormone. Arginine, and ornithine have the ability to influence fat metabolism and stimulate growth hormone. Arginine’s potential impact on weight loss comes from its potential to increase the breakdown of fats. People consuming arginine have reported having more energy and less fatigue.

Grape Seed Extract

Grape seed extract has been reported to have several benefits, among them: antioxidant, anti-inflammatory, immunostimulatory, antiviral, anticancer, cardioprotective, hair growth, inflammation and allergy protective, hepatoprotective, tissue protective, and premenstrual syndrome, vascular, postoperative edema, and skin and wound healing. Grape seed extract contains the antioxidant compound oligomeric proanthocyanidin (OPC) which has been studied for a variety of health conditions. Grape seed extract may have some heart benefits, including lowering systolic blood pressure and heart rate. The lower heart rate may cause the decrease in systolic blood pressure. Grape seed extract is commonly used as a dietary supplement for various conditions, including for venous insufficiency (when veins have problems sending blood from the legs back to the heart), to promote wound healing, and to reduce inflammation. Additionally, The National Center for Complementary and Integrative Health (NCCIH) is supporting preliminary research on grape seed extract for Alzheimer’s disease.

L-Glutamine

Glutamine is the most abundant amino acid in the body, due to its relatively high concentration in the blood and comparatively large stores of free glutamine in muscle. It is found in all proteins, and thus any protein source provides glutamine in the diet. The free form is also found in meat, milk, fruits, and vegetables. Glutamine from the diet and in circulation is extracted by the intestine and is used to support cell growth, energy production, and acts as a substrate for gluconeogenesis. Glutamine also serves as a source of energy and as a gluconeogenic precursor for the kidney. It has been suggested that glutamine can help keep weight off by reducing food cravings and giving more energy to the body. Glutamine is commonly used to lose weight while maintaining the body mass.

L-carnitine

Meat, fish, chicken, and dairy products are rich sources of dietary L-carnitine. L-carnitine claim to be metabolism boosters that can help to lose weight and increase the athletic performance. It has been suggested that carnitine may improve insulin sensitivity and nerve pain in people with type 2 diabetes, increase fertility in men, lower mortality risk in those with ischemic myocardial infarction, or heart attack, result in mild cognitive improvements in older people. Carnitine is often promoted as an aid for weight loss, to improve exercise performance, and to enhance a sense of well-being.
