The 2025 RLS Guidelines Changed Everything — Here's What Your Doctor Hasn't Told You Yet
In 2025, the American Academy of Sleep Medicine reversed a decade of restless legs treatment recommendations. Dopamine agonist drugs — previously the first thing doctors prescribed — were downgraded to last resort because 42–68% of patients experience augmentation, where the drug makes the condition worse over time. The new first step? Check ferritin and supplement iron.†
Your brain uses stored iron (ferritin) to produce dopamine, which runs the sensory filter that keeps your legs quiet when you lie still. When ferritin drops below 75, dopamine falls, the filter fails, and every signal your legs produce gets amplified into the crawling, buzzing, and electricity that forces you to move. The lab says anything above 12 is "normal." The brain needs 75. Most women with RLS have never had ferritin checked.†
- 2025 AASM guidelines now say: check ferritin and supplement iron first, before any drug†
- Dopamine agonists downgraded to last resort — augmentation affects the majority of patients†
- Most doctors are still following the old protocol — magnesium advice, gabapentin, then dopamine drugs†
CHELATED IRON BISGLYCINATE — THE #1 RECOMMENDED FORM
The Right Iron, the Right Form, the Right Pathway
The 2025 guidelines say supplement iron first — but the form matters. Ferrous sulfate, the standard drugstore iron, dumps raw iron into your gut and causes GI side effects in up to 70% of people. Most quit within 2 weeks, long before ferritin can climb. Iron bisglycinate is a completely different molecule — chelated in two amino acids, absorbed through the peptide transport system with zero GI issues, and approximately 4x better absorption at a lower dose. It's the form you can actually take consistently for the months it takes to reach the brain's threshold of 75.†

Formula
Iron Bisglycinate
vs. Ferrous Sulfate
Chelated Absorption — Iron wrapped in two amino acids, absorbed through the peptide transport system without releasing free iron into your gut†
Builds Ferritin to 75 — The brain's threshold for dopamine production. Ferrous sulfate can't get you there because nobody can tolerate it long enough†
Zero GI Issues — No nausea, no constipation, no cramping, no black stool. You can take it every morning and forget about it†
9-in-1 Formula — 65mg iron bisglycinate plus Vitamin C, copper, B1, B2, B6, B12, folate, and zinc to support absorption and dopamine synthesis†
The Research Is Clear.
Iron deficiency is one of the most well-documented causes of restless legs syndrome. The 2025 AASM guidelines now say to check iron first.
Better absorption than ferrous sulfate†
Iron bisglycinate absorbs through the peptide transport system at approximately 4x the rate of drugstore iron, at a lower dose
