Lepidium meyenii, known widely as maca, is a root vegetable that has been cultivated in the Peruvian Andes since 1600 B.C., at altitudes from 8,000 to 14,500 feet. Native Americans and indigenous Peruvians have used maca as a medicine and a source of nutritional support to stimulate the immune system, treat anemia, stomach cancer, tuberculosis, enhance memory, menstrual disorders, menopause symptoms, infertility, sterility and sexual disorders. Maca is widely categorized as a superfood; a food high in micronutrients, essential vitamins and minerals with the power to strengthen cells and cellular response, aid the body in recovering from stress, increase energy and libido.

Micronutrients: Iron and Iodine
Micronutrients are nutrients that are needed in small amounts and are essential to the production of the enzymes and hormones in the body.

Iron is essential for oxygen transport and cell growth.The reccomended daily intake for iron is 45 mg a day for adults over 19. Two teaspoons of maca contains about 1.5 mg of iron. Iodine is necessary for thyroid function and supports a healthy metabolism. The recommended daily intake for iodine is 150 mcg a day for adults. Two teaspoons of maca contains about 52 mcg of iodine.
Micronutrients: Manganese and Zinc
Manganese assists the body in forming connective tissue, bones, blood clots and sex hormones. It aids in metabolism, calcium absorption, and normal brain and nerve function. Manganese is also found in an antioxidant enzyme that balances free radicals in the body. The recommended daily amount of manganese is 2.3 mg for men and 1.8 mg for women. Two teaspoons of maca root powder contains 80 mcg of manganese. Zinc is required for the function of about 100 enzymes. It supports the immune system, synthesis of protein, DNA synthesis and cell division. It helps wounds to heal and is needed for the functions of taste and smell. The recommended daily intake of zinc is 40 mg. In two teaspoons of maca root powder, there are about 380 mcg of zinc.
Major Minerals: Calcium and Potassium
Calcium is essential to your body's vascular functions, muscle function, nerve transmission, cellular communication and hormonal secretion. In every 10 g or 2 tsp. of maca, there are 25 mg of calcium. The recommended daily intake of calcium for men and women over 19 years old is 1,000 mg. Women over 51 require an additional 200 mg. Potassium is a mineral that supports the function of all cells, tissues and organs in your body. Potassium is an electrolyte, which conducts electricity in the body. It aids muscle contraction and function and digestion. The recommended daily intake for men and women over 19 is 2000 mg. In every 2 tsp. of maca, there is 215 mg of potassium.
B Vitamins and Vitamin C
