Can zinc bisglycinate be taken together with other vitamins and minerals? — Zinc Bisglycinate Food Supplement, N90- VitalHarmony

The advantage of zinc bisglycinate in capsules with no other active ingredients is that it is easy to combine with other supplements — you control what you take and in what amounts.

At the same time, zinc has well-known interactions with other minerals:

• Zinc and iron compete for the same transport mechanisms in the intestine. If you take iron preparations, it is best to space them out from zinc — for example, by several hours.
• Zinc and copper are also interrelated: high doses of zinc taken over a long period can affect the absorption of copper. This is relevant primarily when the recommended dosages are exceeded or with very long courses.
• Calcium in high doses may theoretically reduce zinc absorption when taken at the same time, although at standard dosages this effect is usually insignificant.

If you already take a multivitamin complex, check whether it contains zinc — the total amount of the mineral from all sources should not exceed the tolerable upper intake level (25 mg a day for adults, according to EFSA); one capsule of this supplement already provides 15 mg of zinc, that is, 150% of the daily reference intake. This is particularly important because an excess of zinc is just as undesirable as a deficiency.

If you have a chronic condition, take medicines or are unsure how to put together your supplement routine, consult a doctor or pharmacist.
