Description
Evidence Tier · Randomized Controlled Trials
Vitamin C, vitamin D3, zinc, vitamin E and B6 with 500 mg elderberry extract and echinacea.
What It Does
Supports normal immune function.*
How It Works
Vitamin C accumulates in white blood cells. Vitamin D regulates innate immune signaling. Zinc is required for normal immune cell development.
Why This Form
The nutrients with the strongest human evidence for immune function, at Daily Value levels, with elderberry as a supporting botanical.
Clinical Evidence
A Cochrane review of 29 trials examined regular vitamin C and the duration of colds.¹ A meta-analysis of individual participant data examined vitamin D and acute respiratory infections.²
What The Evidence Does Not Show
Regular vitamin C did not reduce how often colds occurred in the general population. Elderberry and echinacea evidence is limited.
