I Almost Quit My Wegovy® Last Month. A Specialist Showed Me Why That Would Have Been The Worst Decision Of My Life.
My GP said the medication wasn't working. Two tests she'd never ordered told a different story — and saved me from making the same mistake thousands of GLP-1 patients are quietly making right now.
I was twenty-eight the first time I fell over in my own kitchen.
The lab work that week showed hemoglobin at 7.4. Ferritin at 4. My internist put me on prescription iron for nine months and told me my body would never forgive me if I let it get there again.
I was forty-one last month when I caught myself reaching for the kitchen counter the same way. Same dizzy moment. Same hot-flush slide down the side of the cabinet. Only this time, I was on Wegovy®. And my doctor wanted me to quit.
I almost did exactly what she said.
The reason I didn't — and the reason I'm writing this now — is what a functional medicine specialist found in two blood tests my regular GP had never ordered in twelve years of appointments. Tests that explained everything.
If you're on Ozempic®, Wegovy®, Mounjaro®, or Zepbound®, and you're starting to feel like the medication is breaking something even though your weight is finally moving — please read this all the way to the end.
The Eight-Minute Appointment
I'd been on Wegovy® for nine months. Down forty-three pounds. My A1C, which had been climbing toward prediabetic for six years, had pulled back into the safe zone. The first six months were the best I'd felt since my early thirties.
Then around month seven, the symptoms started creeping in. The fatigue first. Not "tired after a long day" tired. A leaden, can't-pull-yourself-up-off-the-couch-at-2pm exhaustion.
Then the hair. Brushing in the morning would leave a small clump in the bristles. My ponytail felt thinner.
Then the brittle nails. The dry skin. The brain fog at meetings I'd previously cruised through.
I made an appointment with my GP. She listened for about eight minutes. Pulled my standard labs. Hemoglobin: normal. White count: normal. Basic metabolic panel: normal.
"Your bloodwork looks fine. What you're describing is consistent with patients aren't tolerating GLP-1 medications well. Let's talk about discontinuing the Wegovy® and trying metformin again."
She wrote "medication intolerance" on my chart.
I walked to my car and cried for ten minutes. Forty-three pounds had taken a year of my life to lose. The thought of regaining it was unbearable.
My sister-in-law Beth was the one who slowed me down. Beth is a nurse practitioner at an integrative health clinic. She didn't tell me what to do — she asked me one question.
"Did your doctor run a ferritin? Or methylmalonic acid?"
I'd never heard of either one.
"They're the actual tests for what you're describing. Hemoglobin and serum B12 — what your GP ran — those are the labs that catch it last. Ferritin is your iron storage. MMA is the active marker for B12 at the tissue level. Both can be in the basement while your standard labs still look 'normal.'"
She made me an appointment with Maria Vasquez, RDN — a bariatric and metabolic nutrition specialist.
What The Specialist Found
Maria ordered a panel I had never had run. Ferritin. Methylmalonic acid. 25-hydroxy vitamin D. Red blood cell magnesium. Complete iron panel.
My panel from Maria's clinic. Ferritin in the basement. MMA elevated. Vitamin D insufficient.
"Your ferritin is eleven. Healthy is fifty to two hundred. Your MMA is elevated — your tissue B12 has been low for months even though your serum B12 reads in range. Your vitamin D is twenty-two — anything under thirty is insufficient."
"This isn't medication intolerance. This is the predictable nutritional collapse that happens to GLP-1 patients in months six through twelve when they're not getting the right supplementation. Your symptoms — fatigue, hair, nails, fog — those are the alarm system telling you the tank is empty. Quitting the medication does not refill the tank."
The Two Paths She Laid Out
Path one: stop the Wegovy®. Appetite returns in 3-6 weeks. Weight comes back — 60-80% within 18 months. A1C climbs.
Path two: stay on the Wegovy®. Replenish what the medication and reduced eating have depleted. Ferritin climbs back. B12 stores rebuild. Vitamin D normalizes. Hair stops shedding by month three.
"Path one feels like relief. Path two is recovery. They are not the same thing."
"For a GLP-1 patient, the foundational requirement is a bariatric-grade multivitamin. Forty-five milligrams of bioavailable iron. Methylcobalamin B12 at 1,000 micrograms. Methylfolate. Vitamin D3. The full B-complex. All in a once-daily capsule."
What I Tried First (And Why It Failed)
I went home and started shopping. Centrum Women: 18mg iron, cyanocobalamin B12, folic acid. Not enough. Returned it.
Nature Made iron: constipation, metallic taste, gave up in a week.
One of the new "GLP-1 vitamins" on my Instagram. $59 a month. 12mg of iron. Cyanocobalamin. Same as a One A Day at three times the price.
I went back to Maria embarrassed.
"Most of my GLP-1 patients try two or three brands before they find one that actually meets the bariatric standard."
She handed me a printout. The name at the top was Titan Nutrition Labs.

What Happened Over The Next Six Weeks
I started the next morning. One capsule. With breakfast. Smooth — no metallic edge, no chalk.
✅ Day 3: No stomach upset.
✅ Week 1: Sleeping deeper. Waking up actually rested.
✅ Week 2: The 2pm fatigue started lifting.
✅ Week 3: Back to Maria for a labs check. Ferritin had climbed from 11 to 34.
✅ Week 4: The hair shedding noticeably slowed.
✅ Week 5: I climbed a flight of stairs at the airport without the leaden weight in my legs. I almost cried.
✅ Week 6: Brain fog gone. My nails started growing without breaking.
The GP Appointment
She pulled up my chart. "You didn't stop the Wegovy®."
"I didn't. I went to a functional medicine specialist. She tested ferritin and methylmalonic acid. Both below range. I started a bariatric-grade multivitamin. Most symptoms have resolved."
"Your weight is stable. Your A1C is still excellent. Your ferritin is now thirty-eight. Your MMA is normal. I'm going to be honest with you — I haven't been ordering ferritin on my GLP-1 patients. I should have. Continue what you're doing."

See The Bottle →Questions Women Ask Us Most
Will the iron cause constipation?
The chelated form of iron we use is significantly gentler than ferrous sulfate. Most users tolerate it well even on a small appetite.
Can I take this with my GLP-1 medication?
Most patients can take this alongside their GLP-1 medication. Take with a small meal for absorption.
How long until I notice a difference?
Most users notice changes in energy within 4–8 weeks. Hair changes typically take 3–4 months.
Is this safe for pre-op and post-op bariatric patients?
This formula is built around ASMBS-aligned dosing. Confirm with your bariatric program's RD.
Can men take this too?
Yes. Especially men with diagnosed iron deficiency or on GLP-1 medications.
What if it doesn't work for me?

If You're Reading This At 11pm Wondering Whether To Quit Your GLP-1
I was where you are three months ago.
Phone screen on dim. Browser tab open to your prescribing clinic's contact form. Trying to decide whether to schedule the "discontinuation conversation."
Please don't do it. Not yet.
The medication is doing what it's supposed to do. But the smaller appetite and reduced absorption mean the nutrients your body needs most are quietly emptying out.
Standard multivitamins weren't built for this. On a GLP-1 they don't come close.
The Titan Nutrition Labs Bariatric Multivitamin is the formula my specialist gave me. 45mg iron. Methylcobalamin B12. Methylfolate. D3. Full B-complex, magnesium, zinc. One vegetarian capsule. Once a day.
60-day money-back guarantee. If your bloodwork doesn't move and your symptoms don't improve, send back the bottle. No paperwork.

— Rachel Kessler
P.S. — I saw real changes inside two weeks. My specialist confirmed ferritin replenishment at week three. My GP signed off on continuing the Wegovy® at week thirteen.
P.P.S. — I have a sister who is forty-six and on Mounjaro® and was a month away from quitting because of side effects no one had connected to nutrient depletion. She started Titan three months ago. Her hair stopped shedding inside a month. Her ferritin tripled. She is still on her medication. She is still losing weight.
