What VitaminStack does

• Add your supplements: Search from 50+ common vitamins, minerals, and supplements. Set your dose and frequency — VitaminStack does the math.
• See your nutrient totals: Each supplement is broken down by nutrient so you can see your total daily intake of Vitamin D, Magnesium, Zinc, and more — all in one dashboard.
• Stay within safe limits: VitaminStack shows Recommended Daily Value (RDV) and Tolerable Upper Limit (UL) for nutrients based on NIH guidelines, with color-coded warnings when totals look high.
• Know your interactions (Pro): VitaminStack Pro can warn you when supplements in your stack may interfere with each other.
• Manage your family (Pro): Create separate profiles for members of your household. Each person gets their own stack and dashboard.
• Built for privacy: No account required — everything stays on your device.

FAQ

Is VitaminStack medical advice?

No. VitaminStack is for informational purposes only and is not medical advice. Always consult a healthcare provider before changing your supplement routine.

Where do the RDV and UL values come from?

VitaminStack references nutrient guidance published by the U.S. National Institutes of Health (NIH). RDV and UL values can vary by age, sex, pregnancy status, and other factors, so use the app as a guide and confirm with a clinician when needed.
