PILLAR Performance Ultra Immune C

Don't let a cold keep you down. PILLAR nailed recovery with the Triple Magnesium, and now they've brought that same rigor to immune support. Ultra Immune C delivers high-strength vitamin C, D3, and zinc in a tropical powder that's actually enjoyable — so staying consistent isn't a chore.

Hard training temporarily suppresses your immune system. Add travel, cold weather, and reduced sunlight and you've got a recipe for missed training days. Ultra Immune C targets that window with three nutrients athletes deplete faster than anyone else.

Three Nutrients, One Job: Keep You Training

High-Dose Vitamin C for Front-Line Defense Your body can't make vitamin C, and training burns through it fast. Each scoop delivers 1,000 mg to keep your immune system's first line of defense stocked.

Vitamin D3 to Close the Winter Gap Less sunlight means lower vitamin D — one of the most direct drivers of increased infection risk. Each serving delivers 1,000 IU of D3 to keep your immune response functioning when you need it most.

Zinc to Keep Immune Cells Firing Zinc mobilizes the immune cells that fight off illness. Training depletes it quickly, and a shortfall slows your response at exactly the wrong time. Ultra Immune C delivers 15 mg per serving.

How to Use PILLAR Ultra Immune C

Daily Dose: Mix one scoop (5g) with water or juice. Vitamin C and zinc are both water-soluble — fine on an empty stomach.

Timing: Avoid dairy at the same time; it interferes with zinc absorption.

Pro Tip: Take at the first sign of illness for the best shot at reducing duration and severity. Many pro athletes also cycle onto it during peak training blocks as a preventive measure.

Stop losing training days to something preventable. Ultra Immune C is Informed Sport Certified and keeps your immune system ready when your training load pushes it hardest.
