Key mechanisms affecting Energy + Fatigue

Frequently feeling tired and low energy is not surprising, given the demands of modern living, a very common complaint.

Sleep, physical exertion, diet, stress and a number of other factors affect energy homeostasis in the body.

Metabolic Maca 

Lepidium meyenii, better known as Maca, grows in the highlands of Peru - and has been cultivated for centuries for its nutritional and potential medicinal values1.

People have turned to the plant for sexual dysfunction, fertility, and... low energy.

Multiple studies indicate that Maca is capable of regulating metabolism. Research has demonstrated that Maca extract can improve the symptoms of lipid and glucose metabolism disorder. 

Another study indicated that chemicals isolated from Maca extract had anti-fatigue activity2. Most recently, research has shown that Maca can limit the damaging effects of exercise-induced fatigue in muscle3,4.

The driver of Maca’s energy-boosting properties is thought to be its main active components, chemicals called Macamides. They are thought to exert their effects by binding to CB1 and PPARα receptors to regulate metabolism and energy homeostasis.

The hardiest plant

  • Maca grows high up in the Andes in Peru at an altitude so high (beyond 4000m) that only few plants can survive. It’s this hardiness - and adaptability to survive extremes - that gives the plant exceptional qualities
  • Maca, also known as Peruvian ginseng, is actually part of the Brassicaceae - mustard - family
  • Although cultivated for more than 2,000 years, maca was not give its modern name until the 17th century when Father Cobo, a Jesuit missionary, came across a plant that could manage to grow in the coldest, harshest parts of Chinchaycocha
