Most people waste half of every supplement they buy through bad timing, hidden overlaps, and absorption conflicts. OptiStack reads your stack and tells you exactly when — and why — to take each one.
Free for up to 4 supplements. No card required.
Add every supplement with brand, dose, and form. Flag professional-grade items so we apply tighter rules.
Fat-soluble with dinner. Iron away from coffee. Magnesium at bedtime. Slotted around your real day.
Every recommendation comes with a plain-language explanation, so you learn as you go.
We scan the inactive ingredients in your supplements and flag what's benign, what might block absorption or efficacy, and suggest cleaner alternatives when available.
OptiStack surfaces curated, sourced guidance on absorption, timing, and known interactions. It is not medical advice and does not replace your clinician — especially if you take prescription medications, are pregnant, or have a chronic condition.
We know your stack is personal. That's why your data is encrypted, never sold, and yours to delete anytime. Want an extra lock? Enable optional two-factor authentication in Settings.
Your supplement data is stored securely and never shared or sold.
Add an authenticator app as a second step for your account at any time.
