What's in your slip
Four ingredients. One goal. Clear timing.
Vitamin C7:00 – 9:00 AM
As ascorbic acid with bioflavonoids
A potent antioxidant that protects cells from oxidative stress and is vital for the function of white blood cells.
Vitamin D3 + K27:00 – 9:00 AM
D3 (cholecalciferol) + K2 (MK-7)
D3 is a crucial immunomodulator that most people are deficient in. K2 ensures that the calcium absorbed by D3 is directed to the bones, not the arteries.
Zinc PicolinateWith meals
A highly bioavailable form of zinc, which is critical for the development and function of immune cells and defending against viruses.
Reishi Mushroom7:00 – 9:00 PM
Hot-water extract, beta-glucan standardized
Known as the "mushroom of immortality," it helps modulate the immune system, either boosting it when under attack or calming it when overactive.

Read all reviews →No. A multivitamin spreads dozens of ingredients across a one-size formula — usually in cheap, poorly absorbed forms. Ultimate Immunity contains four ingredients chosen specifically for this outcome, each at a dose that's actually relevant, in bioavailable forms your body can use.
