What To Expect When You Start
When you start giving your body the iron it needs, things start changing faster than you think.
Week 2 — Energy starts coming back
A little more energy. You're not dragging as much. Still early, but something's shifting.
Week 4 — Brain fog lifts
No more afternoon crash. You can actually think again — clearer head, steadier focus.
Week 8 — Steady and strong
Energy lasts all day. Your mood feels more even. The wall you used to hit is gone.
Week 12 — You feel like you again
Iron stores are full. You finally feel like yourself again — maybe even better.
How Does Ferritin Affect Me?
Ferritin is your body's iron storage.
When it drops, your body sends iron to vital organs and cuts off everything else — your energy, your focus, your mood.
You need healthy ferritin to feel like yourself.
SYLENE Iron Restore rebuilds your reserves in weeks — so you get your energy and yourself back.
Powered by 10 Clinically-Studied Ingredients
Iron Bisglycinate
A chelated, highly absorbable form of iron. Goes straight into your blood. No constipation. No bloating. No nausea.
Lactoferrin
Lactoferrin lowers hepcidin — the hormone that blocks iron absorption — so more iron reaches your ferritin stores.
Vitamin C + L-Lysine + Copper
Vitamin C, L-Lysine, and Copper work together to help your body absorb more iron and actually convert it into ferritin.
B6, B12 & Folate
B6, B12, and Folate help your body turn stored iron into healthy red blood cells — so ferritin gets to your muscles and brain.
Zinc & Selenium
Zinc and selenium support the body's iron regulation — controlling how your body uses iron for steady energy.

Try Risk-Free TodayYour Questions, Answered
You may not know for certain without a blood test, and that's the point: the symptoms overlap almost perfectly. Fatigue, brain fog and low mood show up in both — so they get blamed on hormones by default. But while you still have your cycle, heavier perimenopausal periods drain iron faster than your body replaces it. If you've felt drained despite "normal" results, low ferritin is one of the most common and most overlooked causes. We always recommend confirming your iron levels with your doctor.
Routine bloodwork usually checks hemoglobin, not ferritin — your stored iron. You can be "in range" and still feel exhausted and foggy, because your body drains its reserves long before anemia appears. Many practitioners consider ferritin below 50 too low to feel your best. If you've been told you're fine while feeling anything but, SYLENE was made for exactly that gap.
It's the #1 reason women quit iron. Standard iron (ferrous sulfate) absorbs poorly, so most of it sits in your gut. SYLENE uses iron bisglycinate, a gentle chelated form absorbed up to 4x better and far easier on digestion. Most women who couldn't tolerate iron before take SYLENE daily without issues.
Most women notice steadier energy and a clearer head within 3 to 4 weeks, with the fullest results around month three, once iron stores are genuinely rebuilt. That's why we back it with a 90-day money-back guarantee.
SYLENE targets your iron, not your hormones, so it doesn't compete with hormone therapy. That said, because iron interacts with certain medications and shouldn't be combined with other iron supplements without guidance, please check with your doctor or pharmacist if you take prescription medication, including HRT. (Contains milk/lactoferrin.)
Take your daily capsules on an empty stomach — about an hour before breakfast or two hours after a meal — for best absorption. One simple step, once a day.
Each bottle is a 30-day supply (60 capsules, 2/day). For real results, plan for 3 bottles (90 days): iron stores rebuild gradually, and consistency makes the difference.
Orders are processed in 1–3 business days. In the US, delivery then takes roughly 5–9 business days. You get a tracking number as soon as it ships.
Then it costs you nothing. Every order is backed by our 90-day money-back guarantee. If you don't feel the difference, contact us within 90 days for a full refund.
You choose: a single supply or subscribe & save. Because rebuilding ferritin takes about three months, many women subscribe so they never break the routine. No lock-in — pause, change or cancel anytime.
