Built for Female Biology
You don't need more supplements.
You need the right ones for you.
Evely analyzes your stack against your goals, your biology, and your life stage — then tells you what to keep, what to cut, and what to change.
Evely doesn't sell supplements. We evaluate what you're already taking and tell you what's actually right for your body — with no financial interest in the answer.
From our pilot cohort
Real women. Real changes.
"My iron wasn't absorbing — I was taking it with coffee every morning."
A simple timing change was the only fix I needed. My ferritin levels finally moved after two years of supplementing with no progress.
— Sarah, 41
"I cut 6 supplements and feel better."
I thought more was better. Evely showed me I was stacking forms that competed with each other for absorption. Simplified down to 5 and felt the difference in two weeks.
— Rachel, 44
"Switched one form. Finally sleep through the night."
I had no idea magnesium oxide barely absorbs. Switched to glycinate, adjusted the timing. Three weeks later, I sleep 7+ hours consistently for the first time in years.
— Maya, 38
The difference
Stop subsidizing the supplement industry.
Start investing in your biology.
A typical picture — before and after an Evely supplement audit.
12
bottles / month
- ✕Redundant ingredients across 4 products
- ✕Wrong magnesium form — barely absorbed
- ✕Iron blocking zinc absorption
- ✕Ashwagandha wrong timing for her cycle
- ✕~$340/month — most of it ineffective
4
targeted essentials
- ✓Each supplement earns its place
- ✓Right forms, right dosing
- ✓Timed to her hormonal cycle
- ✓Gaps addressed based on her labs
- ✓~$95/month — all of it intentional

Why this is so hard
The supplement industry wasn't built to help you decide.
It was built to sell you more.
More bottles. More trending ingredients. More conflicting advice from experts who've never looked at your labs, your cycle, or your life stage. And almost none of it accounts for female physiology — dosing studied in men, timing that ignores your hormonal cycle, formulations optimized for absorption in male subjects.
The result: you're spending money, doing the research, taking the pills — and still guessing.
How Evely works
Your supplement decision layer.
Share your stack and health context
Tell us what you're taking. Add your goals, symptoms, life stage, and — optionally — your lab results or wearable data. Takes 3 minutes.
Get clear answers
What to keep, what to cut, what to change. Plus timing guidance, form recommendations, and interaction flags — calibrated to your biology, not a male-default average.
Track what's working
A light feedback loop, including biomarkers to check, so you can see whether your supplements are making a difference — and know when it's time to adjust.
Takes 3 minutes to get started.

Under the hood
Evely goes deep, so you don't have to.
Interaction & Safety Audit
Automated checking for supplement-to-supplement and supplement-to-medication conflicts across your full stack.
Bioavailability Intelligence
Evaluation of formulations (e.g., Magnesium Glycinate vs. Oxide) to ensure your cells are actually absorbing what you take.
Female-Specific Dosing
Protocol adjustments for perimenopause, menopause, cycle phases, and life-stage transitions — not male-default reference ranges.
Biomarker Attribution
Direct mapping of your stack to changes in HRV, deep sleep, ApoB, and inflammation markers when lab or wearable data is available.
Your data stays yours.
FAQ
Questions & answers
Those quizzes are designed to sell you their products. Evely evaluates supplements across all brands, checks for interactions and redundancies, and calibrates to female physiology — not to a product catalog.
Yes. If you're starting from zero, Evely uses your labs, symptoms, life stage, and health goals to recommend a starting point built for your biology — not a generic list. You only take what your data suggests you actually need.
Yes. Whether you're taking 3 or 15, the question is the same: are these the right ones for you? Even a short stack can have the wrong forms, wrong timing, or gaps that matter for your goals.
Yes. Your hormonal cycle, life stage, and any hormonal shifts you're experiencing are central to how Evely evaluates your stack. Timing, dosage, and which forms you should take can change based on where you are hormonally.
No. Tracking data adds depth, but the analysis is useful without it. You can always connect data later for a deeper picture.
It depends on the supplement. We give you specific timelines for each — usually 2–8 weeks — with clear markers to monitor. No more guessing.
