Hormonal Imbalance

• Maca root is said to contain more than 55 phyto-chemicals including hormonal precursors and sterols, which may lead to increased libido and stamina. Because it can alter a person's hormonal levels, this herb can lead to hormonal imbalance. Some women, for instance, have reported acne breakouts, water retention or bloating, mood swings and hot flashes when taking maca supplements. Other noted side effects, which are most probably related to hormonal imbalance, include upset stomach, headaches, heartburn and increased heart rate.
  
  

Reverse Symptoms

• Some people find that hormonal symptoms such as acne breakouts and bloating may actually be relieved with the help of maca root because it stabilizes hormone levels. Some have reported that their skin cleared up with continued use of this supplement. In other cases, side effects such as increased sexual drive may be seen as an unwanted side effect; someone taking maca root for hormonal symptoms may not desire the increased libido.
  
  

Hashimoto's Hypothyroidism

• While maca root is generally beneficial for users with thyroid problems, individuals suffering from Hashimoto's hypothyroidism are encouraged to avoid maca root and use black currant oil instead. According to user feedback posted on SoulCysters.net, maca root can bind thyroid hormones, making them unstable at the cellular level in the case of individuals with Hashimoto's hypothyroidism.
  
  

Goiters

• The raw maca root contains the chemical glucosinolate, which is known to be a direct or indirect cause of goiters. According to SkinCareTalk.com, when the glucosinolate in maca root is combined with a low-sodium diet, it can increase the development of goiters.
  
  

Allergies

• As with any drug or food type, some people are allergic to the maca root and may develop rashes, itchiness, hives, redness of skin and fatigue after it has been digested. Any allergic reactions should be reported to your physician so quick corrective action can be taken.
