Five Ingredients. Multiple Roles.
A healthy immune system depends on adequate nutrition, cellular signaling, and antioxidant defenses. Immune Active brings together two essential nutrients and three additional compounds with complementary biochemical functions.
Immune Function
Vitamin C and zinc contribute to the normal function of immune cells.
Antioxidant Support
NAC supplies a precursor used in glutathione synthesis, while quercetin and green tea provide polyphenols.
Convenient Formula
Five active ingredients in a two-capsule daily serving.
Immune Active Ingredient Breakdown
The following amounts reflect the U.S. product’s listed two-capsule serving. Always compare against the label on the bottle you receive.
| Ingredient | Amount | Why It Matters |
|---|---|---|
| Vitamin C | 200 mg | Supports normal immune function and antioxidant activity. |
| Zinc (as zinc glycinate) | 30 mg | Essential for immune-cell function and many enzyme systems. |
| N-Acetylcysteine (NAC) | 600 mg | Provides cysteine used in the production of glutathione. |
| Quercetin | 250 mg | A plant flavonoid studied for antioxidant properties. |

What Makes This Formula Interesting?
The distinguishing feature of Immune Active is its combination of essential immune nutrients with compounds involved in antioxidant pathways.
Vitamin C and Zinc
Both nutrients are required for normal immune function. However, more is not automatically better: additional supplementation is most useful when it addresses an actual dietary or physiological need.
NAC and Glutathione
NAC provides cysteine, an amino acid needed to synthesize glutathione, one of the body’s important antioxidant compounds. This biological role does not establish that the finished supplement prevents illness.
Quercetin and Green Tea Polyphenols
Quercetin and EGCG are plant compounds studied for their antioxidant and cellular signaling effects. Laboratory findings should not be confused with proven clinical outcomes from taking this particular formula.
The Just Simply Well Perspective
What I appreciate about this formula is the combination of established essential nutrients with additional antioxidant compounds. I also think it is important to evaluate the complete formula, particularly its zinc content and green tea extract, rather than assuming every immune supplement is appropriate for everyone.
How to Use Immune Active
Manufacturer directions: Take two capsules daily or as directed by your healthcare practitioner. Follow the instructions on your specific product label.
Important Considerations
Zinc: The two-capsule serving contains 30 mg. The adult tolerable upper intake level for zinc is 40 mg daily from all sources. Review other supplements containing zinc before combining products. Prolonged excessive zinc intake can interfere with copper status.
Green tea extract: Concentrated extracts have been associated with rare liver injury. People with liver conditions or other relevant risk factors should seek professional advice before use.
Medications and special populations: Ask a qualified healthcare professional before use if pregnant, nursing, taking medication, or managing a medical condition. Keep out of reach of children.
Do not use a bottle with a broken or missing safety seal. Store according to the manufacturer’s instructions.
Frequently Asked Questions
Is Immune Active a multivitamin?
No. It is a targeted combination of vitamin C, zinc, NAC, quercetin, and green tea extract rather than a complete daily multivitamin.
Can I take it with another supplement?
Possibly, but review overlapping ingredients, especially zinc. Medication interactions and individual health circumstances also matter.
Does Immune Active prevent colds?
The finished product should not be assumed to prevent or treat colds or other infections. Its ingredients support normal physiological functions, but that is not the same as demonstrating disease prevention.
How many servings are in one bottle?
A 60-capsule bottle provides 30 servings at two capsules per serving.
