You ate the spinach. You spaced the calcium. You took the pills with orange juice, the way you were told. And still the bloodwork came back low, or “low normal,” and still you felt it.

Here’s what no one explained: swallowed iron has to survive your stomach, and most of it doesn’t. Food blocks it. Acid degrades it. What’s left often just sits there, which is why the pills upset your stomach without moving your numbers.

Change the route and everything changes.

OYO absorbs through the lining of your mouth, before digestion ever gets involved. No food rules. No nausea. Just iron your body can finally use.
