Zinc picolinate and Magnesium glycinate: interaction, severity and spacing
Zinc picolinate and Magnesium glycinate interact because zinc and magnesium compete weakly for absorption. Clinical impact is small unless both are taken in large doses at once. Take them 2 hours apart. Mild risk.
The interaction in detail
| Pair | Zinc picolinate and Magnesium glycinate |
|---|---|
| Type | Nutrient interaction |
| Severity | Mild |
| Required spacing | 2 hours minimum |
| Onset | At the time of dosing |
Mechanism
Zinc and magnesium compete weakly for absorption. Clinical impact is small unless both are taken in large doses at once.
What to do
No change needed at typical doses. If you take 30 mg+ zinc, separate it from magnesium by 2 hours.
How to fit both into one day
Zinc taken with food reduces nausea but phytates block it, so use a chelated form. Sustain high doses only alongside copper.
Magnesium supports parasympathetic tone and muscle relaxation, so evening dosing also helps sleep. Keep it two hours from antibiotics and thyroid medication.
Putting Zinc picolinate in the evening and Magnesium glycinate in the evening satisfies the 2-hour separation without disrupting either one's absorption window.
