The Ritual

Immunity isn’t built in a day, it’s built through consistent daily habits. ActiFizz is designed to be part of your everyday routine, not just something you reach for when you’re run down.

Take it daily, not just during illness, and pair it with good hydration, quality sleep and regular movement for best results.

Serving size: 1 tablet per day, for adults and children aged 12 and over. Dissolve one tablet in a glass or bottle of water, leave it to fizz fully, then drink. Great before exercise or at any time of day.

The Science

Vitamin C contributes to the normal function of the immune system, a reduction of tiredness and fatigue, normal collagen formation for the normal function of bones, cartilage and teeth, normal psychological function, and the protection of cells from oxidative stress.

Vitamin D3 contributes to the normal function of the immune system, the maintenance of normal bones and teeth, normal muscle function, and normal blood calcium levels.

Zinc contributes to the normal function of the immune system, normal protein synthesis, the maintenance of normal bones, normal cognitive function, and the protection of cells from oxidative stress.
