For an adult patient experiencing medication-induced hair shedding, I would recommend a daily zinc supplement dosage of 15-20 mg, rather than 100 mg. This is because high doses of zinc can cause adverse effects such as gastrointestinal upset, copper deficiency, and immune system suppression. A lower dose of zinc aspartate, such as 15-20 mg per day, is generally considered safe and effective for supporting hair growth. It's also important to note that zinc supplements should be taken in conjunction with other nutrients, such as biotin and vitamin D, to support overall hair health. If the patient's hair shedding persists or worsens, I would recommend consulting a dermatologist or healthcare provider to rule out any underlying medical conditions and to discuss alternative treatment options. Additionally, it's essential to monitor the patient's zinc levels and adjust the supplement dosage as needed to avoid excessive intake.
Is 100 mg of zinc (Zn) aspartate excessive for an adult patient experiencing medication-induced hair shedding?
