Free 90-Day Guide included with every order twelve pages
Hair works in ~90-day cycles. Most women shouldn't judge anything before 8 to 12 weeks. That's biology, not marketing. It's also why our guarantee runs the full 90 days.
Chelated bisglycinate was chosen specifically because classic ferrous salts are hard on digestion. Take it with a meal, not on an empty stomach. If it still does not agree with you, the 90-day guarantee covers that too.
Three variables decide whether iron works: the form, the gatekeeper, the duration. Most products get one right. See the three variables, then read our label.
Your body rations iron. Hair is last in line. Ferritin is the reservoir your follicles draw from; this formula is built to refill it: chelated iron, lactoferrin, active-form cofactors.* Full mechanism further down this page.
Three bottles every 90 days, $79.98 each time. That is one full hair cycle per delivery, which is the shortest honest way to judge anything here. Same price today and on every renewal, with no introductory rate that climbs later. Pause, skip, or cancel anytime from your account, in one click, no fees. The 90-day guarantee starts the day your first order is delivered.
The Reservoir Formula is made in small batches, to order. Every order ships with tracking, and you get the number as soon as it moves. Your 90-day guarantee starts the day the bottle arrives, not the day you order, so a slow week never eats into your window.
THE 90-DAY TIMELINE
What refilling a reserve actually looks like
WEEKS 1-4
The reserve refills first
Gentle iron + lactoferrin go to work where it matters: your ferritin reserve. Nothing shows in the mirror yet, and that is expected.*
WEEKS 5-8
The drain often slows
As the reserve climbs, many women notice less hair in the brush.*
WEEKS 9-12
New growth begins its cycle
Follicles draw from a fuller reservoir, the start of a new cycle. The earliest honest point to look at your part line, or your ponytail.*
Illustrative timeline based on the hair growth cycle. Individual results vary.
Two capsules. One job.
Chelated iron bisglycinate, 100 mg of lactoferrin, and active-form cofactors in a clean two-piece capsule, designed to help iron get in, and stay.*
BEFORE THE MECHANISM
The elastic that suddenly needs one more turn. The brush that fills up faster than it used to. The drain you check before anyone else.
This isn’t vanity. It’s a pattern.
-
Your ponytail is half the size it was, and you know exactly when it changed.
-
A doctor told you your bloodwork was normal, while your hair kept falling.
-
You have taken iron before, given it a few weeks, and quietly stopped.
-
You feel tired in a way that a good night of sleep does not fix.
If even one of those felt familiar, keep reading. There is a reason it keeps happening, and it is not the one you have been told.
And if none of them did, this probably is not your product. That is fine.
THE MECHANISM
Your body rations iron. Hair is last in line.
Iron runs the essentials first: oxygen transport, energy production, muscle repair. When intake drops or reserves run low, the body triages. The follicle sits at the bottom of that priority list, so hair is often where a shrinking reserve shows up first.*
Iron does more than hair. It carries oxygen, and it feeds the everyday work of your cells.* Hair is simply where a reserve running low tends to show up first, because it is last in line.
A reserve running low does not announce itself. It shows up as a day that takes more out of you than it should, and a mirror you start avoiding in the morning.
THE PRIORITY QUEUEVital functions first. Hair last.
THE RESERVOIR
Ferritin is the reservoir.
Ferritin is the stored form of iron, the reserve that carries you between meals, cycles, and demanding seasons. Standard panels screen for anemia; fullness is a question they were never built to answer. “Normal” and “replenished” are two different questions.*
IRON RESERVEMany women run closer to empty than they think.
WHY IRON FAILS
Three variables decide whether iron works.
Most products only tell you about one.
The Form
Cheap ferrous salts are poorly absorbed and famously hard on the stomach. Chelated bisglycinate is built for absorption, without the churn.*
The Gatekeeper
Your body caps how much iron it lets through, with a hormone called hepcidin, and inflammation tightens that cap. Lactoferrin is the milk-derived protein studied at this exact step, at the 100 mg we dose.*
The Duration
Hair lives in ~90-day cycles. Two weeks proves nothing, in either direction. Consistency is the third variable.
EVERY MILLIGRAM
What's inside, and what each one does.
-
HPMC SHELL
A plant capsule. Nothing else in it.
-
LACTOFERRIN · 100 MG
Studied at the gate that decides how much iron gets through.
-
IRON BISGLYCINATE · 45 MG
Gentle on the stomach.* Built for week twelve, not week one.
-
ACTIVE-FORM COFACTORS B12 · FOLATE · P5P
Iron in the blood is not iron in storage. These move it across.
-
L-LYSINE · 400 MG
Studied in women whose levels would not move on iron alone.
-
MINERALS AND VITAMIN C
- VITAMIN C · 120 MG
- ZINC · 10 MG
- COPPER · 1 MG
- SELENIUM · 55 MCG
Iron does not act alone. These four go with it.
Every layer. Every dose. Nothing else.
More iron is not faster.
Sixty-five milligram formulas race the gut, not the reserve. Past what your transporters can carry in a day, the extra stays unabsorbed, and unabsorbed iron is what cramps. Forty-five milligrams, escorted and absorbed, refills more than seventy that never make it through.*

Full ingredient list
Ten ingredients. Every dose printed, nothing rounded, nothing hidden behind a blend.
Iron (as ferrous bisglycinate) 45 mg · Lactoferrin 100 mg · L-Lysine (as L-Lysine HCl) 400 mg · Vitamin C (as calcium ascorbate) 120 mg · Zinc (as zinc bisglycinate) 10 mg · Copper (as copper bisglycinate) 1 mg · Selenium (as L-selenomethionine) 55 mcg · Folate (as L-5-MTHF) 400 mcg DFE · Vitamin B12 (as methylcobalamin) 100 mcg · Vitamin B6 (as P5P) 10 mg.
Allergens
Contains: Milk (lactoferrin).
Lactoferrin is a protein naturally concentrated in the first milk. It is the reason this formula exists, and the reason it is not dairy-free. We would rather tell you than let you find out.
Capsule material
HPMC, a vegetable cellulose capsule. No gelatin, no animal-derived shell.
Made to order
Every batch is produced to order, in small quantities, rather than sitting in a warehouse. That is why shipping takes longer than most supplements, and why the guarantee starts the day your bottle is delivered rather than the day you order.
What we don't use
No proprietary blends. No ingredient folded into an umbrella name. Every milligram is on the label, which is why the label is photographed on this page rather than described.
READ ANY LABEL LIKE THIS

Hold any brand to it, including us.
- 01 Iron form Chelated bisglycinate, not a cheap ferrous salt.
- 02 Elemental dose Clearly stated per serving, not buried in a total.
- 03 Lactoferrin Actually on the label. It's the expensive line many skip.
- 04 Cofactors in active forms Methylated B12 and folate, P5P.
Not all iron is built the same. Here's how The Reservoir Formula reads against the patterns on most mass-market “hair” irons.
Comparison reflects common patterns across mass-market iron supplements. Always read individual labels. Ours is printed in full on the bottle, photographed in the gallery at the top of this page.
BEFORE YOU ASK
Questions, answered straight.
How do I take it?
Two capsules daily, with a meal, at roughly the same time each day. Coffee, tea and calcium compete with iron at absorption: give the capsules a two-hour distance. Consistency over a full cycle is the whole job.
I've tried iron before and it did nothing.
Iron that fails usually fails for one of three reasons: the compound it is bound to, what closes the gate on absorption in the same window, or a course stopped before a full cycle. Our piece on chelated iron and iron salts covers the first, and what competes with iron at absorption covers the second. The third is the calendar, and it is the one most people lose. See the three variables, then read our label rather than taking our word for it.
Will it upset my stomach?
Honestly: iron can be hard on a stomach, and pretending otherwise would be a poor start. Across 43 randomised trials, ferrous sulfate roughly doubled the odds of stomach trouble against placebo. We chose chelated bisglycinate for that reason, and the protocol says with a meal rather than on an empty stomach. What the same research says about dose and schedule, including the part that does not flatter us, is in why iron is hard on a stomach.
Can I take this with my medication, including a GLP-1?
We can't advise on medications. That's your physician's call, and it's the right first stop. Bring the full label; it hides nothing.
Who shouldn't take it?
If you have an iron-overload condition such as hemochromatosis, or you've been told to keep your iron low, please talk to your doctor before starting. This formula is built for women looking to support healthy iron reserves, not for everyone across the board.
Is it vegan / dairy-free?
No, and we'd rather tell you than hide it. Lactoferrin is a milk-derived protein; it's also one of the reasons this formula exists. Contains: Milk (lactoferrin).
I'm pregnant or breastfeeding, can I take it?
Please talk to your physician first. Iron needs in pregnancy and nursing are real, and individual. This label was written to be shown to a doctor.
How long does delivery take?
Delivery within 9 to 15 business days, tracked the whole way. The 90-day guarantee starts on delivery day.
That figure runs from the day you place the order, not from the day it ships. If anything takes longer than what we told you, write to us and we will make it right.
How does the 90-day guarantee work?
Email us within 90 days of delivery. We refund you. You keep the bottle: no return label, nothing to ship back, no interrogation.
That last part matters more than it sounds. Many money-back guarantees in this category require the product back before they refund, which quietly makes a claim harder to file. A formula you're asked to judge over a full 90-day cycle shouldn't have to be in the post to be refunded.
