1,000 mg and 3,000 mg of high-potency vitamin C in a fizzy, fruity stick you'll actually crave. Zero sugar. Built for people intentionally seeking ultra-dose vitamin C — not minimum daily requirements.
Ultra-dose is the term UltraVitas uses for high-potency vitamin C formulas that deliver substantially more vitamin C than standard daily nutritional requirements. Rather than formulating around minimum nutritional adequacy, we offer 1,000 mg and 3,000 mg vitamin C formulas for consumers intentionally seeking higher-potency supplementation. It's our terminology — not a medical dosage classification.

Ultra-dose is the term UltraVitas uses for high-potency vitamin C formulas that deliver substantially more vitamin C than standard daily nutritional requirements — currently 1,000 mg and 3,000 mg per stick pack.
Read the full ultra-dose vitamin C explainer for how it compares with standard intake references.
"Ultra-dose" is UltraVitas terminology, not an established medical or scientific dosage classification.
UltraVitas does not formulate around minimum nutritional requirements. Our ultra-dose formulas are made for people intentionally seeking substantially higher vitamin C intake.
The established adult upper intake level of 2,000 mg per day reflects the increased likelihood of gastrointestinal effects at higher intakes rather than a sharp toxicity threshold, and individual tolerance varies. Anyone with a medical condition, taking medications, or with questions about high-dose supplementation should consult a qualified healthcare professional.
Gastrointestinal effects such as gas or loose stools are the most commonly reported response to higher vitamin C intakes, and they are the main reason an upper intake level exists.
Individual tolerance varies at ultra-dose levels. Many people find it settles as their routine becomes consistent; if it doesn't, try a lower-potency formula such as UltraVitas Immunity (1,000 mg) or speak with a qualified healthcare professional.

It depends on what you're taking and what you're looking for:
*Individual results may vary.
UltraVitas was built around a different idea: minimum nutrition isn't the same as high-potency nutrition. Our formulas are designed for people intentionally seeking ultra-dose vitamin C rather than products formulated only around minimum daily nutritional requirements.
All in convenient vitamin C powder sticks with naturally delicious fizzy flavors, zero sugar, rich in antioxidants, and no caffeine.
*Individual results may vary.
Like a treat, not a chore. Each flavor is crafted to taste naturally delicious — not chalky, bitter, or artificially sweet.
Zero sugar, low calorie, and a satisfying fizz when you mix it in cold water. You'll actually look forward to your daily ultra-dose vitamin C stick.
We recommend cold or room-temperature water for the best experience. Here's why:
Immunity Kids is specifically designed for children, with age-appropriate dosages of 17 essential nutrients at 100% DV each — including 250 mg vitamin C, calcium, and vitamin K2.
It's coming soon — sign up for our newsletter to be first to know when it launches! Our adult ultra-dose formulas (Immunity, Immunity Play, Beauty) are formulated for grown-ups and are not recommended for children.
