Zinc Supplements
Zinc is an essential trace mineral involved in hundreds of enzymatic reactions throughout the body. It plays a foundational role in immune function, protein synthesis, wound healing, DNA synthesis, and cell division. Zinc is also critical for normal taste and smell perception, and it is required for the activity of over 300 enzymes. Because the body has no dedicated zinc storage system, consistent daily intake through diet or supplementation is important for maintaining adequate levels.
At Best Vitamins Online, we carry zinc supplements from professional-grade brands including Thorne, NOW Foods, Pure Encapsulations, Bluebonnet Nutrition, and Douglas Laboratories. Multiple forms are available to suit different absorption needs and tolerability preferences.
Zinc Forms & Their Differences
- Zinc Picolinate — Bound to picolinic acid; one of the most studied and well-absorbed forms of zinc
- Zinc Bisglycinate — A chelated form bound to two glycine molecules; highly bioavailable and gentle on the stomach
- Zinc Citrate — Bound to citric acid; good bioavailability and widely used in general-purpose formulas
- Zinc Gluconate — A common, cost-effective form frequently used in lozenges and general supplements
- Zinc Carnosine — A compound of zinc and L-carnosine; specifically researched for gastric mucosal support
- Zinc + Copper Combinations — Long-term zinc supplementation can deplete copper; combination formulas help maintain the proper balance

Frequently Asked Questions
What is the best form of zinc to take?
Zinc picolinate and zinc bisglycinate are among the most bioavailable and well-tolerated forms. Zinc citrate is also a solid general-purpose option. Zinc oxide, while common in some products, has lower bioavailability compared to chelated forms. The best choice depends on your individual needs and tolerance.
Should I take zinc with food?
Yes. Zinc is best taken with food to reduce the risk of nausea, which can occur when zinc is taken on an empty stomach. Avoid taking zinc at the same time as high-phytate foods (such as whole grains and legumes), which can inhibit absorption.
How much zinc should I take daily?
The recommended dietary allowance (RDA) for zinc is 8–11 mg per day for adults. The tolerable upper intake level is 40 mg per day. Long-term supplementation above 25–30 mg daily may interfere with copper absorption, so zinc+copper combination formulas are often recommended for extended use.
Can zinc and copper be taken together?
Yes — and for long-term zinc supplementation, it is often advisable. High zinc intake can compete with copper absorption. Many professional-grade zinc supplements include a small amount of copper (typically 1–2 mg) to maintain the proper mineral balance.
