Can Immunity-Boosting Supplements Keep You From Getting Sick?
Supplement Quality Varies
Not all supplements are created equal and unfortunately, the supplement market isn’t heavily regulated. That means some supplements you buy might not truly contain the strength of nutrients they promise to, and others can have binders and fillers that diminish their potency – or even make you feel sick.
Your best bet is to find supplements with a USP label. This means they have been tested by the USP Pharmacopoeial Convention Dietary Supplement Verification Program. It is worth noting that a very small percentage of supplements on the market don this label.
