Immune supplements? Here’s what the data says…

Billions of dollars flow into ads promoting supplements that claim to boost your immune system and prevent infection. You’ll see the taglines - “supports a healthy immune system!” - everywhere. Well, what’s the research say? Let’s take a look…

Note: You should only ever take vitamins after taking a DNA test and a blood nutrient level test to determine safe and effective doses. Click here to learn more about how your DNA impacts your nutritional requirements..

 Vitamin C

Truth: Regular vitamin C supplementation may marginally reduce the duration and severity of colds but starting vitamin C supplementation after you’ve become sick seems to have no effect. The exception is in the athletes population that undergoes intense exercise, where regular vitamin C supplementation seems to help prevent colds. Sources: [1] [2] [3] [4]

Zinc

Truth: Zinc lozenges seem to help reduce the duration of cold symptoms when started immediately at the onset. Preliminary evidence in the elderly shows some benefit from oral zinc supplementation in reducing infections, but the data did not reach significance. Sources: [1] [2] [3]

Vitamin D

Truth: Vitamin D plays a role in regulating immune cells and a deficiency can impair immunity. This statement is supported by epidemiological evidence showing an association between low vitamin D levels and an increased risk of upper respiratory tract infections (viral). In addition, a meta-analyses (completed in 2017) determined supplemental vitamin D may help prevent upper respiratory tract infections. Sources: [1] [2] [3] [4] [5]

Vitamin E

Truth: Increased T-cell mediated immunity has been demonstrated with vitamin E supplementation in elderly populations. This benefit does not translate to younger populations. Sources: [1] [2] [3] [4]

--- Botanicals ---

The evidence is shaky at best as we enter the herbal category, with most evidence being mixed or study populations not large enough to reach significance. 

Echinacea

Truth: May reduce the risk of upper respiratory tract infections but data is scarce. Benefits are small at best. Sources: [1] [2]

Elderberry

Truth: While understudied, elderberries may reduce duration and severity of colds and even the flu. Please note, the elderberry plant is poisonous and the berries must be prepared properly. Sources: [1] [2] [3]
