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 โ 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 โ SCAN ANY PRODUCT Point your camera at a supplement. In seconds, see what's really inside: โข A 0โ100 quality score across thousands of products โ form, dose, testing, brand โข Bioavailability of every form (magnesium glycinate vs oxide isn't a label โ it's 4% vs 90% absorption) โข Toxicity flags on questionable compounds โข Third-party-tested badges โ only when actually verified We show the form, the dose, the data โ and we show our work. SYMPTOM SOLVER โ 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 โ ranked by evidence: โข Strong / Moderate / Emerging tiers โ no false confidence โข The right form, the clinical dose, the timing, the mechanism โข Linked to the studies โข 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 โ every item sourced, every product scored. Borrow what holds up. Skip what doesn't. STACK AUDITOR โ IS YOUR STACK ANY GOOD? Add everything you take. MoodStack audits it in one shot: โข A composite quality score for your whole stack โข Overdose warnings when you're doubling up โข Weak forms flagged โ with a better swap โข Redundancies (you're paying twice for the same thing) โข Gaps โ what's missing for your goals โข Cheaper alternatives: same compound, better form, lower price โข Nutrient coverage from your actual stack โ real numbers, not generic charts SMARTER ALTERNATIVES Every product comes with comparable alternatives ranked by quality, price, and bioavailability. Stop overpaying for marketing โ find the same compound in a better form for less.
