3/10 Mostly Legit
High confidence

Hype Score

0 = legit, 10 = all hype

"It's a basic four-ingredient immune support supplement with Vitamin C, D3, Zinc, and Selenium at unspecified doses."

Similar to Nature Made Immune Support, Centrum Immune Support, or any grocery store multivitamin ($12-18 for 60 capsules).
Real benefit May modestly support immune function if you're deficient in any of these nutrients; otherwise, minimal benefit over a standard multivitamin.
The catch You're paying $49.95 for commodity ingredients that cost $0.15-0.25 per dose wholesale—a 3-5x markup over comparable products—and the page doesn't even list the doses.
