FAQ
- What is the best supplement for immune support?
- There's rarely a single best — the options below are the supplements most commonly used for immune support. Evidence strength varies by ingredient and by person. Favor a form from a brand with independent third-party testing (NSF, USP Verified, Informed Sport), and check with a healthcare professional before starting.
- Are immune support supplements FDA-approved?
- No. The FDA regulates supplements as food, not drugs — they aren't approved for safety and effectiveness before sale. That makes third-party testing and certification the most useful quality signal, which is what we point to.
- Do supplements replace medication for immune support?
- No. Supplements are not a substitute for prescribed treatment. This page is general reference, not medical advice — talk to a licensed professional, especially if you take medication.
