The Problem

You're probably throwing away $30-60/month on supplements that don't work for your cycle

→You buy supplements based on generic 'women's health' labels, not your actual cycle phase — so you're taking the wrong things at the wrong time

→You have no system for when to take what — your bathroom cabinet is a expensive guessing game

→Cycle syncing sounds good in theory, but you can't figure out which supplements actually matter for follicular vs luteal phase — so you buy everything and use nothing consistently

→Your energy, mood, and PMS symptoms stay the same because your supplement stack isn't aligned to your hormonal reality

→You've spent $200+ testing different brands, different combos, different timing — and still don't know what actually works for you

The Solution

Your cycle's personal pharmacist

CycleDay merges real-time cycle tracking with personalized supplement recommendations. You log your phase, symptoms, and goals. Our algorithm recommends exactly what to take, when, why, and in what dose — based on your individual cycle and current needs. No fluff. No upselling. Just phase-optimized supplementation.

📅

Know your exact cycle phase in real time

Log your cycle once. CycleDay tracks you daily, telling you which phase you're in right now and what your body needs this week.

💊

Get phase-specific supplement recommendations

Follicular phase needs iron and folate. Luteal phase needs magnesium and calcium. We tell you exactly which supplements matter for YOUR phase, and which ones you can skip.

⏰

Precise timing and dosage for every supplement

Don't just know WHAT to take — know WHEN and HOW MUCH. Our recommendations include optimal timing (morning with food, evening, etc.) and dose ranges based on your goals.

🎯

Customized to your symptoms and goals

Whether you're fighting PMS, optimizing fertility, managing energy crashes, or smoothing mood swings — your recommendations shift based on what you actually need right now.

💰

Stop buying supplements you won't use

Our recommendation engine shows you the 3-5 core supplements that actually matter for your phase. You skip the noise, save money, and finally see results.

📊

Track what works (and stop what doesn't)

Log your mood, energy, symptoms, and how you're feeling on your current stack. See patterns. Know what's actually moving the needle for you.
