Zinc is vital for the human body as it contributes, among other things, to the strengthening of the immune system, wound healing, and energy production. In zinc supplements, we encounter the following forms:

• Zinc gluconate, which is the most common form, is easily absorbed by the body and its consumption is tolerated without causing discomfort.
• Zinc sulfate, with a high metal content. It is recommended for those with a significant deficiency, although it may cause stomach discomfort.
• Zinc picolinate, with high bioavailability, which is easy to absorb.
• Zinc citrate, intended for individuals with a sensitive stomach.
• Chelated zinc (zinc bisglycinate), with very high absorption that causes fewer side effects.

Tips & Advice for Safe Consumption of Zinc Supplements

1. Consume zinc on an empty stomach or with a light meal that does not contain calcium or fiber for better absorption.
2. Do not exceed the recommended dose, as excessive zinc can cause nausea, vomiting, diarrhea, and headache. Indicatively, the recommended daily dose is 11-12 mg for adult men and women who are pregnant or breastfeeding, 8 mg for adult women, and 2-8 mg for children, depending on their age.
3. Choose the right form of zinc according to your needs. For example, if you are a vegetarian and have a diagnosed zinc deficiency, then zinc glycinate is ideal for you. Meanwhile, if you have a sensitive stomach and exercise frequently, opt for zinc citrate for immediate muscle recovery.
4. Finally, combine zinc with vitamins C and B6 for immune and metabolism boost, magnesium to reduce stress and fatigue, or selenium for the proper functioning of the thyroid. Avoid consuming it in combination with medications, such as antibiotics, as their effectiveness is reduced.
