OptiZinc® 120 Tablets by Source Naturals – Immune Support Zinc Supplement
OptiZinc® tablets by Source Naturals provide 30 mg of zinc as a methionine sulfate complex, alongside 300 mcg of copper, in a vegetarian tablet. This zinc supplement pairs a specific zinc form with a smaller amount of a second essential mineral rather than offering a broad multivitamin blend.
The 120-tablet bottle is intended for a once-daily routine with a meal. Its focused formula is worth considering when you need to review zinc intake separately from other nutrients. Because each tablet supplies more zinc than most adults need from their entire daily diet, choosing it should include a review of foods, multivitamins, and other zinc-containing products.
Key OptiZinc® Benefits
- Provides zinc for normal immune-cell development and communication, supporting the everyday work of both innate and adaptive immune defenses.
- Supplies an essential mineral involved in making proteins and genetic material, helping maintain normal cell growth and tissue renewal.
- Includes copper for mineral-dependent enzymes that participate in iron handling, energy production, and maintenance of connective tissue.
How OptiZinc® Works
Zinc helps enzymes carry out chemical tasks throughout the body. It also helps proteins maintain their shape and participates in signals that guide cell activity. These roles connect immune support with everyday processes such as protein synthesis, DNA synthesis, and normal tissue maintenance.
In this formula, zinc methionine sulfate complex supplies the zinc, while copper citrate supplies copper. The minerals have related but distinct nutritional jobs. Added copper does not make excessive zinc intake appropriate, and this formula should not be combined automatically with additional zinc supplements.
Key Functional Ingredients Include:
- Zinc: Supports the development, activation, and normal function of immune cells. Zinc helps cells communicate and enables enzymes to build and maintain proteins and genetic material. These functions support normal immune defenses and the ongoing renewal of body tissues.
- Copper: Helps enzymes use iron, produce cellular energy, and maintain connective tissue. Copper also participates in the body's antioxidant enzyme systems. Its inclusion provides a complementary essential mineral, but does not guarantee protection against the effects of excessive zinc intake.
OptiZinc® Is Formulated For
- Adults reviewing their need for focused daily mineral support rather than a broad combination formula.
- People seeking a vegetarian tablet with clearly stated zinc and copper amounts.
- Adults who want to discuss a 30 mg zinc serving with their healthcare practitioner.

Other Ingredients: microcrystalline cellulose, modified cellulose gum, silica, stearic acid, and magnesium stearate.
Does Not Contain: Contains no yeast, dairy, egg, gluten, corn, soy or wheat. Contains no starch, preservatives, or artificial color, flavor or fragrance.
Additional precautions: Zinc can cause nausea, stomach upset, vomiting, dizziness, headache, or appetite loss. Excessive long-term intake can reduce copper absorption. The adult upper limit is 40 mg daily from all sources unless medically supervised. Ask your pharmacist about separating zinc from quinolone or tetracycline antibiotics and penicillamine. Thiazide diuretics can increase zinc loss, and taking high-dose iron alongside zinc can reduce zinc absorption. Discuss copper-containing supplements with your clinician if you have a copper-handling disorder.
Frequently Asked Questions About OptiZinc®
What are the benefits of OptiZinc®?
OptiZinc® provides zinc for normal immune function, protein production, and the maintenance of genetic material. Each tablet supplies 30 mg of zinc as zinc methionine sulfate complex, plus 300 mcg of copper as copper citrate. Copper contributes to enzymes involved in iron use, cellular energy, and connective tissue maintenance. This is a focused mineral supplement, not a multivitamin, so its usefulness depends on how these amounts fit your existing diet and supplement routine.
Who should take OptiZinc®?
OptiZinc® is an option for adults who have identified a reason to add zinc and want a vegetarian tablet containing both zinc and copper. Its 30 mg zinc serving is higher than the usual daily dietary requirement, so it is not automatically necessary for everyone. Review your other supplements before adding it. If you are pregnant, may become pregnant, or breastfeeding, the manufacturer directs you to consult your health care professional before using this product.
Are there any side effects of taking OptiZinc®?
Zinc can cause nausea or stomach upset; excessive intake can reduce copper absorption. Ask your pharmacist about antibiotic or penicillamine interactions, thiazide diuretics, and high-dose iron. The label states: If you are pregnant, may become pregnant, or breastfeeding, consult your health care professional before using this product. Do not use if either tamper-evident seal is broken or missing. Keep out of the reach of children. Each tablet contains 30 mg zinc, so account for other zinc sources and discuss long-term use with your practitioner.
How does OptiZinc® support overall health?
OptiZinc® supplies two trace minerals with different everyday roles. Zinc helps enzymes and proteins carry out tasks involved in cell signaling, normal cell division, and immune function. Copper supports iron handling, connective tissue formation, and energy-producing enzymes. Together, they contribute to mineral nutrition rather than replacing a varied diet. Follow the label direction of one tablet daily with a meal, and review ongoing use with your practitioner rather than assuming that a higher zinc intake offers greater benefits.
