Formula story
Immunity is where UltraVitas ultra-dose starts today. Each stick delivers 1,000 mg of vitamin C inside a broader vitamin-and-mineral formula, made for people who want high potency without jumping straight to the current 3,000 mg formulas.
Dose
One stick pack provides 1,000 mg of vitamin C — 1,111% of the Daily Value. That is well above standard daily nutritional requirements, and it is the starting point of the current UltraVitas ultra-dose range rather than a fixed recommendation for everyone.
Formula
Immunity is a 15-ingredient formula: vitamin C alongside vitamins A, D and E, a complete B-complex including B3, B6 and B12 at 500% DV, plus zinc at 200% DV, manganese and selenium. Full amounts and Daily Values are listed in the Supplement Facts below.
Flavor
High-potency vitamin C does not have to feel medicinal. Immunity uses a crisp Apple flavor with zero sugar and 13 calories per stick pack, so the daily habit is something you can look forward to.
Experience
Each serving is pre-portioned in a single-serve powder stick — no scoop, no measuring. It slips into a bag or a desk drawer and dissolves into cold water in seconds.
UltraVitas Immunity is designed as the more approachable current ultra-dose formula. It delivers 1,000 mg of vitamin C per serving, substantially above standard daily nutritional requirements, without assuming that one dose is right for everyone.
What does ultra-dose mean?Who Immunity may fit
A strong fit for someone who wants the UltraVitas high-potency approach at 1,000 mg of vitamin C per serving, in a daily Apple-flavored powder stick.
