MoodStack vs Tonic

What's actually in your bottle? Most supplement apps just remind you to take pills. MoodStack tells you whether what you're taking actually works — and what's a waste of money. Built for people who refuse to take stuff on faith. Powered by real science: bioavailability data, form quality, clinical doses, third-party testing, peer-reviewed sources. Updated as the evidence evolves. No marketing. No vibes. TRUTH SCORE — SCAN ANY PRODUCT Point your camera at a supplement. In seconds, see what's really inside: • A 0–100 quality score across thousands of products — form, dose, testing, brand • Bioavailability of every form (magnesium glycinate vs oxide isn't a label — it's 4% vs 90% absorption) • Toxicity flags on questionable compounds • Third-party-tested badges — only when actually verified We show the form, the dose, the data — and we show our work. SYMPTOM SOLVER — WHAT ACTUALLY WORKS FOR YOUR PROBLEM Sleep. Focus. Low energy. Anxiety. Joint pain. Gut. Libido. Recovery. Skin. Immunity. And more. Pick what's bugging you and get the supplements that actually help — ranked by evidence: • Strong / Moderate / Emerging tiers — no false confidence • The right form, the clinical dose, the timing, the mechanism • Linked to the studies • Mythbusters: the popular "fixes" that don't survive the research, called out by name CELEBRITY STACKS What Andrew Huberman, Bryan Johnson, and other evidence-driven optimizers actually take — every item sourced, every product scored. Borrow what holds up. Skip what doesn't. STACK AUDITOR — IS YOUR STACK ANY GOOD? Add everything you take. MoodStack audits it in one shot: • A composite quality score for your whole stack • Overdose warnings when you're doubling up • Weak forms flagged — with a better swap • Redundancies (you're paying twice for the same thing) • Gaps — what's missing for your goals • Cheaper alternatives: same compound, better form, lower price • Nutrient coverage from your actual stack — real numbers, not generic charts SMARTER ALTERNATIVES Every product comes with comparable alternatives ranked by quality, price, and bioavailability. Stop overpaying for marketing — find the same compound in a better form for less. PEPTIDES LIBRARY Clear, sourced explainers on BPC-157, GLP-1s, NAD+, GHK-Cu and more — what the evidence says, without the hype.

Tonic reads the clinical research on 201 supplements so you don't have to — and tells you the honest truth, including when something probably isn't worth your money. Most supplement apps either dumb the science down to star ratings or bury you in studies. Tonic does something different. It keeps two questions apart, because mixing them up is exactly how people get misled: • How SURE is the science? (Strong → Moderate → Limited → Early) • How BIG is the effect? (Notable → Little-to-none) So melatonin reads honestly: very certain science, but a modest effect. Creatine reads as strong evidence AND a real effect. And the trendy stuff reads as "interesting, but too early to say" — instead of a miracle. WHAT'S INSIDE • 201 supplements graded from the human research — vitamins, minerals, herbs, amino acids, probiotics and more • Plain-English summaries written for a smart friend, not a scientist • A study field behind every claim — see how many trials, and how many people, stand behind it • Scan any supplement label — the camera reads the ingredients and grades each one on the spot, entirely on your phone • Honest safety notes and clear "check with your doctor" flags • Build your stack and let Tonic optimise it — clashes to space apart (like minerals that block each other's absorption), when to take what, natural pairings, and gaps worth filling with the best-proven candidate • A 60-second quiz that grades what you already take — and finds an evidence-based starter stack • Share any verdict as a clean, honest card — including the "save your money" ones • Optional daily reminders for your morning and evening stack (everything stays on your phone) HONEST BY DESIGN Tonic is free. No ads. No account. It collects no data — everything stays on your phone. It exists to answer one question: is this actually worth taking? Tonic is educational and is not medical advice. Always talk to a qualified healthcare professional before changing what you take, especially if you take medication or have a health condition.
