Maca Facts

Maca is a plant that originates in the Peruvian Andes and grows at altitudes of 11,000 feet (3500 m) and above. This makes it the highest growing food crop in the world. The maca plant grows in rocky soils, which are commonly inhospitable to most other vegetation. And it thrives in extreme climactic conditions such as freezing cold, intense sunlight and strong winds. The Maca plant produces leaves as well as a small root, about the size of a radish. It is the root that has been treasured for thousands of years due to its medicinal ability to naturally increase energy, endurance and fertility for all people and animals who eat it.  No doubt Maca root has made a sustainable work life possible in the very high mountains for generations of indigenous people.

Maca History

The history of the ancient maca plant dates back all the way to the 1500’s. It has been used for centuries in the Andes for nutrition and to enhance the fertility of both humans and animals. Maca was probably domesticated between 1300 and 2000 years ago in San Blas, Junin (present day Peru) by Incan farmers. The first written account of the root comes from Cieza de Leon (1553). In 1653, Spanish priest Cobo referred to the use of the root for fertility and as a stimulant. In the central Andes, maca continues to be used as a daily source of food after it has been dried at greater than 20 grams per day.

Maca Nutrition Facts

Maca has powerful nutritional benefits. Dried maca roots nutritional content consists of 13-16% protein, 8.5% fiber, 19 essential amino acids, vitamins A, B1, B2, B3, C and D, minerals iron, magnesium, copper, zinc, sodium, potassium, calcium, several glucosinolates, 20 free fatty acids, and unique compounds called macaenes and macamides.  Beyond that, Maca is one of only a handful of foods considered to be an "adaptogen," or a food that raises overall life force energy.

How Maca Works

Maca is a nutritional powerhouse that is dense in amino acids, vitamins and minerals. It is also an adaptogen, which means that it supports overall health and strength. Research has revealed that maca works to boost the overall physical functioning of the body as well as to lift mood.

Maca and Hormones 

Maca is considered to be very beneficial for hormone balancing, endocrine and thyroid function enhancement and even immune system enhancement. These benefits are most likely related to its high content of amino acids. Hormones are constructed of amino acids and cholesterol.

Maca as an Adaptogen

Maca root, like ginseng, is also an adaptogen. Adaptogens are substances that raise the physical body’s state of resistance to diseases through physiological health and emotional health improvements. These effects make maca a broad-based superfood that in many cases is able to balance and rejuvenate overwhelmed, tired adrenal glands and other aspects of the hormonal system, unlike coffee which stresses the adrenal glands.  Over time, use of maca can lead to several benefits including greater energy, stamina, improved mood, and the ability to handle stress.
