The problem
Why your immune system struggles without enough Vitamin C
Low or inconsistent Vitamin C intake leaves four key systems under-supported. Here is what goes wrong — and how each one is answered.
- 01
Depleted immune reserves
Vitamin C is used up quickly by immune cells. Low daily intake means reserves run low exactly when your body needs them most.
Answered by1000 mg dailyContributes to the normal function of the immune system, with a dose your body can draw on every day.
- 02
Unchecked oxidative stress
Without enough antioxidant input, free radicals build up from daily stress and environment.
Answered byL-ascorbic acidContributes to the protection of cells from oxidative stress, every single day.
- 03
Slow collagen turnover
Vitamin C is essential for normal collagen formation. Too little slows tissue renewal across skin, gums and vessels.
Answered byCollagen cofactorContributes to normal collagen formation for skin, bones, cartilage, gums, teeth and blood vessels.
- 04
Reduced iron absorption
Plant-based (non-haem) iron needs Vitamin C to become absorbable — low intake limits what your diet delivers.
Answered byIron uptakeVitamin C increases iron absorption from the meal it is taken with.
