Ingredients for Immune Support

2,912 products · 37 forms
Vitamin D acts like a sunlight‑triggered switch that helps your gut absorb calcium and keeps bones and muscles working properly. It also talks to immune and brain cells, which is why people look at it for infection risk and mood. Think of it as a hormone‑like nutrient that matters most if you’re running low.
- Support bone strength and help reduce fracture risk when combined with calcium
- Reduce risk of acute respiratory infections
- Improve depressive symptoms/mood

Vitamin C
3,154 products · 65 forms
Vitamin C is the body’s water‑soluble rust‑proofing: it neutralizes free radicals, helps enzymes build collagen, and supports immune defenses. Think of it as a maintenance crew for connective tissue and a small but real helper against everyday infections. Topically, concentrated L‑ascorbic acid can brighten and smooth sun‑worn skin.
- Support immune defenses and shorten common cold duration
- Modestly lower blood pressure (especially if hypertensive/diabetic)
- Reduce oxidative stress and inflammatory markers
- Improve signs of photoaging and fine wrinkles (topical)

Zinc
1,085 products · 159 forms
Zinc is an essential mineral your immune system, skin, and metabolism use every day. Think of it as a small but busy toolkit—helping enzymes work, supporting antiviral defenses in your throat and nose, and keeping skin inflammation in check. When diet is low or needs are higher, short-term supplements or targeted forms (like lozenges) can fill the gap.
- Shorten the duration of common colds
- Support healthy blood sugar in type 2 diabetes or prediabetes
- Help manage inflammatory acne
- Support sperm quality in men with fertility concerns
