Iron pills were designed decades ago, for a generic gut and a generic body. OYO was designed for women whose bodies are in transition — when sensitivity is higher, absorption is harder, and the stakes of consistency are real.
Perimenopause changes the rules. Heavier periods, shifting hormones, and recovery that takes longer. OYO is designed to meet your body where it actually is — with gentle, consistent iron support that works with your life, not against it.
By your 40s, your digestive system is more sensitive — and traditional iron pills make it worse. OYO dissolves on your tongue and absorbs directly through your oral mucosa, bypassing your stomach entirely. No nausea. No constipation. Just iron your body can finally use.
You're at the peak of your career, running a household, caring for family on both sides. Low iron steals the energy you need for all of it — and perimenopause makes the deficit worse. OYO helps restore the ferritin levels that fuel real, sustained energy.
One strip a day. No water, no meal timing, no empty-stomach rules. Slip the tin in your bag and take one whenever fits your day. Consistency is where iron actually works, and we've made consistency effortless.
100% vegan, gluten-free, no artificial fillers, no metallic taste. Raspberry flavor sweetened with monk fruit — nothing you don't need. Because what you put in your body at this stage matters more, not less.

Four simple steps. No pills to swallow, no timing rules, no compromise.
One strip. Any time of day. No water, no food, no rules. Fits into a life you're already running.
The strip melts on your tongue, releasing 19mg of iron directly into the mucosal lining of your mouth.
Iron enters your bloodstream through your oral mucosa — bypassing the digestive system that makes pills so rough on women in their 40s and 50s.
With daily use, ferritin levels rebuild over 6–12 weeks. More stable energy, clearer focus, less of that mid-afternoon collapse.

Iron builds in your body over weeks, not days. That's why we give you a full 60 days — enough time to actually notice the difference. If you don't feel more energy, better focus, or easier consistency, we'll refund you in full. No hassle, no awkward questions.
START YOUR 60 DAYSPlace one strip on your tongue and let it dissolve — about 20–30 seconds. No water, no food, no meal timing. Take it any time of day that fits your routine. Most women take it alongside something they already do daily, like morning skincare.
No. Iron pills pass through your digestive system, which is why they cause nausea, cramping, and constipation — especially for women whose bodies are more sensitive in their 40s and 50s. OYO absorbs directly through your oral mucosa, completely bypassing your stomach.
During perimenopause, periods often get heavier, longer, and more unpredictable — which silently depletes iron over months and years. Many women attribute the resulting fatigue, hair thinning, and brain fog to “just getting older” when iron is actually the cause. Rebuilding ferritin levels is one of the most impactful changes you can make at this stage.
Most women feel more energy and clearer focus within 3–6 weeks of daily use. Ferritin levels rebuild more slowly — we recommend staying consistent for at least 8–12 weeks and retesting with your doctor. Iron works on a timeline of months, not days.
Yes. 100% vegan, gluten-free, lactose-free. No artificial colors, no gelatin, no common allergens. Sweetened with monk fruit, flavored with natural raspberry.
60-day money-back guarantee. If OYO isn't working for you, email us and we'll refund you in full — even if you've opened the tin. No forms, no questions.
Iron is often recommended during pregnancy and postpartum, but we always suggest checking with your healthcare provider before starting any new supplement in those stages.
