Maca is wonderful for increasing energy, strength and stamina. For a start, it is full of minerals, vitamins, and protein, containing many of the essential amino acids, and particularly rich in calcium and magnesium, so it can help to deal with any deficiencies in the diet. Due to its high calcium levels, it's often used to treat osteoporosis and bone density problems.
Maca is very popular among both men and women for its ability to balance hormones. So it is often taken by women suffering during the menopause, or with PMT, and it increases libido (it's sometimes known as Peruvian Viagra!), and helps with fertility issues. It contains plant sterols, the natural form of steroids, and is used by athletes to help improve performance. Because it gives you such a boost, it is particularly helpful for people who suffer from chronic fatigue or are depressed.
It has a sweet, malty taste that can be sprinkled into yoghurts, smoothies and porridge. Start with a teaspoon a day and build up to 2.
