Best Supplements for Immunity
4 evidence-based options for immunity, summarized from the research: what they do, how to dose them, and how they work together.
Probiotics
Beneficial bacteria for gut and immune balance.
Vitamin C
Antioxidant vitamin and iron-absorption amplifier.
Vitamin D3
The sunshine vitamin behind bone, immune, and mood health.
Zinc
An immune and hormone workhorse trace mineral.
Combinations to know
How these supplements pair with each other and beyond.
Vitamin C + Zinc
Frequently combined for immune support during cold season.
Probiotics + Zinc
Zinc helps maintain the integrity of the gut lining.
Iron + Vitamin C
Taken together, vitamin C can multiply the absorption of plant-based iron.
Calcium + Vitamin D3
Vitamin D3 is required to absorb dietary and supplemental calcium.
Magnesium + Vitamin D3
Magnesium is required to convert vitamin D into its active form, so low magnesium blunts D3's benefits.
Vitamin D3 + Vitamin K2
K2 directs the calcium that D3 helps absorb into bone rather than soft tissue and arteries.
