Ferritin 12 → 68 in 3 months.

"My doctor wouldn't approve an infusion because my ferritin was 'only' 12. I'd tried 3 other supplements — all made me sick. 3 months of Felt Iron later — ferritin at 68. My doctor actually said 'wow.'"

Will it actually raise my ferritin — or just my iron levels?

Ferritin is exactly what Felt Iron targets. Most iron supplements raise serum iron temporarily without building ferritin stores — because they're poorly absorbed. Sublingual delivery bypasses the digestive inhibitors (coffee, calcium, phytates) that block absorption. Women using Felt Iron typically see ferritin rise measurably within 8–12 weeks of consistent use.

I've tried "gentle" iron before. It still destroyed my stomach. Why would this be different?

Because "gentle" still means oral. Bisglycinate, ferrous gluconate, slow-release — every pill form passes through your digestive tract. That's where the damage happens. Felt Iron dissolves under your tongue. Iron enters your bloodstream directly. Your stomach is never involved — not less involved. Never.

My doctor says my ferritin is normal. Do I actually need this?

Lab "normal" starts at 15. Optimal for women is 50–100. At 27, you're technically "in range" — and running on empty. Most doctors test for deficiency, not for optimal function. If you're exhausted, losing hair, or struggling with focus despite normal labs, your ferritin is likely the missing piece.

How long before I feel a difference?

Most women notice something in weeks 2–3 — usually energy first, then sleep quality, then focus. Hair changes take longer (month 2–3). Ferritin shows measurably on bloodwork around week 8–12. The key difference with Felt Iron: you'll actually stay on it long enough to get there. No stomach pain means no reason to quit.

What if it doesn't work for me?

Any stomach discomfort in your first 30 days — full refund, instantly. No questions. Keep the strips. We offer this guarantee because the entire promise of Felt Iron is zero stomach involvement. If your stomach reacts, we failed — and you shouldn't pay for that.

why every iron supplement you've tried has failed you.

The problem was never your commitment. 
It was where the iron went.

1

It hits your stomach first.

Every pill — even "gentle" iron — passes through your digestive tract. That's where the cramping, bloating, and nausea happen. Every single time.

2

So you stop taking it.

The side effects become unbearable. You quit. Your ferritin stays low. The fatigue, brain fog, and hair loss stay with it.

3

And the cycle repeats.

New brand. Same stomach. Same result. 40% of women abandon iron supplements within the first month — not from lack of trying, but because the format makes it impossible to continue.

Yes, we know. 'Gentle iron' wasn't.

Bisglycinate, chelated, slow-release — they all still dissolve in your gut. 'Gentle' just means the irritation hits slower. Sublingual is different by design, not by marketing. The iron never reaches your digestive tract. There's nothing to be gentle about.
