Ultra-dose vitamin C powder sticksthat taste incredible.

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.

*Individual results may vary.

It depends on what you're taking and what you're looking for:

• Energy metabolism* — B-vitamins at 500% DV support the body's normal energy metabolism
• Immune support* — daily and cumulative; consistency matters more than any single serving
• Beauty (collagen & skin)* — collagen studies commonly run 8–12 weeks of daily use

*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.

• 1,000 mg ultra-dose vitamin C (1,111% DV) in Immunity
• 3,000 mg ultra-dose vitamin C (3,333% DV) in Immunity Play and Beauty
• 500% DV of B3, B6 & B12 across the Immunity family
• 200% DV zinc for immune & skin support*
• Beauty adds 2,500 mg collagen + 1 billion CFU probiotics

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.

• Immunity — crisp Apple
• Immunity Play — bright Lemon
• Beauty — smooth Korean Plum

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:

• Heat can degrade vitamin C, reducing the potency you're paying for
• The signature fizzy effervescence works best in cold water — it's part of the fun
• Room temp is fine if you prefer still drinks — just avoid boiling or very hot water

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.
