Maca Root – A Comprehensive Guide

Maca has long been recognized by the Peruvian people as a herbal cure for many forms of ailments due to hormone imbalance. In spite of its huge reputation as a medicinal plant in the Andes highlands for thousands of years, it is only lately that maca root stepped into the limelight of the natural wellness community. Its recently acquired status as a superfood is well-earned, however. Clinical tests and research continue to find more health gains derived from this amazing root crop.

What is Maca?

Maca (Lepidium meyenii) is a native root crop in the Andes regions of Peru and belongs to the cruciferous plant species. Being of the same family, its appearance is similar to turnips and radishes, with root colors that range from yellow and red to black. The root has an agreeably refreshing taste. After being harvested and processed, maca root is available at online retailers, drugstores and specialty health food stores in powder, capsule, extract or liquid form. It even comes in gelatinized form with less starch for easier digestion. Maca root is regarded as an adaptogen, a term given to herbs and substances found in nature that help the body adapt naturally to stress triggers like challenging jobs, work deadlines, and illnesses. Apart from that, the maca root is known to be a rich source of essential micronutrients and antioxidants. Research has shown that it can help the body achieve hormonal balance, enhance memory and mood, increase energy, and promote sexual health, among other things.

Health Benefits of Maca Root

Maca Root is Rich in Nutritional Content

Maca root is a very good source of protein, essential vitamins, and minerals which include iron and copper, plus a good amount of dietary fiber. It is packed with a rich supply of health-giving phytonutrients and more than 20 amino acids (with all eight essential amino acids included). Around 2 tablespoons or an ounce of maca root powder may contain about:

  • 4 grams of protein
  • 2 grams of fiber
  • 1 gram fat
  • 20 grams of carbohydrates
  • 80 milligrams of vitamin C (133% Daily Value)
  • 0.3 milligrams of vitamin B6 (16% Daily Value)
  • 70 milligrams of calcium (7% Daily Value)
  • 560 milligrams of potassium (16% Daily Value)

  • 0.1 milligrams of riboflavin (6% Daily Value)
  • 0.2 milligrams of manganese (11% Daily Value)
  • 1.7 milligrams of copper (84% Daily Value)
  • 91 calories

Maca root also contains plant compounds that include polyphenols and glucosinolates.

Maca Root is High in Antioxidants

Antioxidants help eliminate the damaging free radicals that can adversely affect the body’s wellness, prevent cell destruction, and provide resistance to chronic diseases. Maca root is a natural antioxidant booster that help raise the levels of superoxide dismutase, glutathione, and other antioxidants in the body. A 2014 study has shown that polysaccharides derived from maca demonstrated powerful antioxidant action that proved highly effective in preventing free radical damage. In a Czech Republic animal study, it was found that giving rats a concentrated dose of maca improved the antioxidant activity in their body and considerably lowered cholesterol and triglycerides levels in the liver. It also decreased blood sugar and hindered the development of chronic illness. A study of maca leaf extract showed that its antioxidant content could protect the body against neurological damage. Improving the body’s antioxidant status is important for preventing the onset of illnesses like diabetes, coronary disease, and cancer through oxidative stress and cell damage prevention. Despite these positive test results on lab animals, further studies are required to learn how the antioxidants in maca root can impact human beings.

Maca Root Can Improve Mood, Energy and Memory

Regular users have reported that maca root powder has made them more energetic, alert and motivated, usually right after they’ve added it to their diet. Taken in the prescribed amount, maca produces that alert feeling without the jittery side effect that comes with caffeine. Test results have demonstrated that maca root can affect energy and stamina in a beneficial way. Keeping energy levels up can positively affect mood. Earlier studies of maca have shown that it may diminish the signs of depression. It is not yet certain how maca raises energy levels. However, it is confirmed to aid in preventing the sudden rise and fall in blood sugar and keeping the normal functionality of the adrenal glands which control energy and mood. Maintaining positive energy levels may also help in keeping weight under control. Various studies have also shown results that memory and concentration gain a lot of benefits from the use of maca root. In 2011, two animal studies have shown that black maca has improved the memory in mice, most probably due to its enhanced antioxidant activity.

Maca Root Can Enhance Athletic Performance

Bodybuilders and athletes have started taking maca root powder supplements to boost their energy and enhance their performance. There are numerous claims that the supplement helped athletes achieve better muscle growth, gain more strength, and improve overall performance. At present, there is a lack of scientific data to support the claims of increased strength or muscle growth. Some test animals fed with maca have shown better performance in endurance tests. A small study conducted on male cyclists showed that they were able to finish a 25-mile bike ride significantly faster after taking maca extract supplements for two weeks.

Maca Root Can Benefit Female Sexual Health

Various studies have demonstrated that maca root may improve female sexual dysfunction and increase their sex drive in a lot of ways. A study focused on how maca root affects post-menopausal women who suffer from sexual dysfunction due to the use of antidepressants. Maca root was able to improve sexual function considerably when tested against a placebo. A similar study found that maca root worked well to raise the sex drive and improve sexual function in women. Post-menopausal women who were studied in 2008 showed improvement in their sexual function and psychological symptoms after taking maca root. As a matter of fact, maca root brought down the women’s anxiety and menopause-related depression after undergoing treatment for six weeks. Destabilized hormone levels in women can lead to symptoms like weight gain, infertility, bloating and can negatively affect reproductive health in general. Maca root has been found to stabilize female sex hormones and provide relief to menopausal symptoms.

As a Topical Application, Maca May Act as a Skin Protectant

Exposed and unprotected skin can be damaged by the sun’s ultraviolet (UV) rays. Long and constant exposure to UV rays can lead to premature wrinkles and even increase the chances of skin cancer. Collected data have shown that a topical application made from a concentrated form of maca extract can help protect the skin from the harmful effects of ultraviolet radiation. A study revealed that concentrated maca extract applied to the skin of test rats for three weeks prevented skin damage from exposure to ultraviolet rays. The UV protection is credited to the presence of glucosinolates and polyphenol antioxidants in maca root. As an important reminder, maca topical application should not be used in place of the time-honored sunscreen. Additionally, it only works as a UV protectant when applied directly to the skin, not when taken orally as a supplement.

Maca Root Can Stabilize Estrogen Levels

A woman’s reproductive system is regulated mainly by the female hormone estrogen. If this important hormone gets out of balance, a lot of unpleasant symptoms could arise that can range from bloating and irregular menstruation to mood swings. Too high or too low estrogen levels can also make ovulation and pregnancy difficult. Maca root can help stabilize and maintain hormone levels and regulate the amount of estrogen in a woman’s system. The International Journal of Biomedical Science published a study involving post-menopausal women who were administered either a maca tablet or a placebo twice a day in a four-month period. Those who took maca tablets had their hormone levels balanced and bone density increased. Apart from those, hot flashes, night sweat, and other menopausal symptoms were also alleviated. Besides cutting down the symptoms of menopause, stabilizing estrogen levels can also aid in boosting women’s reproductive health and fertility. It can also reduce symptoms associated with disorders like polycystic ovary syndrome (PCOS) such as weight gain, acne outbreak, and excessive hair growth.

Maca Root May Reduce Prostate Size

The prostate gland can only be found in men. It can become enlarged in a condition known as benign prostatic hyperplasia (BPH) which usually occurs in older men. An enlarged prostate gland can cause urination issues, among other problems. It surrounds the urethra and its enlargement can constrict the urethral tube where urine passes, making urination quite difficult. Several studies involving rodents indicated that red maca can reduce prostate size. The red maca’s reducing effect on the prostate is attributed to its high glucosinolate content. The glucosinolate components in maca has been linked with the lowered risk of prostate cancer.

Maca Root Can Boost Male Fertility

Can maca root work for men as well? Previous studies have shown that maca root powder can boost male fertility and also improve sexual health. A study in Peru have demonstrated that using maca for two months heightened the sexual desire in male test subjects. A similar study held in 2001 showed that maca root can aid in enhancing sperm quality and motility (movement) which are essential factors for determining male fertility. Maca root can also be beneficial for sexual dysfunction. Four clinical research studied how maca affects male libido. Two of the studies reported an improvement in sexual dysfunction and increased libido in male and female subjects. The two other studies did not show positive results and required more time for research.
