Gender and Age
Gender and age significantly affect nutrient requirements. Generally, adult men require more zinc than women, mainly due to its role in testosterone production.
However, older adults may have slightly different needs, as both zinc and magnesium absorption decrease with age.
Athletes or those engaging in strenuous physical activities may require higher doses to compensate for greater mineral loss through sweat and to support muscle recovery.
Your existing diet is crucial in determining your ZMA needs. If you consume foods rich in zinc, magnesium, and vitamin B6, you may require a lower supplemental dose.
Existing Medical Conditions
Individuals with certain medical conditions may need to adjust their dosage accordingly. For instance, people with kidney disease should avoid taking excessive magnesium.
Always consult a healthcare provider if you have a medical condition or are taking other medications.
