Your Surgery Changed
Your Anatomy.
Your Vitamins Never Caught Up.
Most multivitamins were designed for bodies that absorb normally. After bariatric surgery or GLP-1 therapy, yours doesn't. Titan delivers the clinical-grade doses your surgeon actually recommends. One capsule. Once a day.

Your Body Can't Absorb
Like It Used To. That Changes Everything.
After bariatric surgery or on GLP-1 medications like Ozempic and Mounjaro, your digestive system handles nutrients differently. The deficiencies that follow aren't hypothetical. They're happening right now.
Iron Deficiency Hits Up to 45% of Patients
Reduced stomach acid and bypassed intestinal surface destroy iron absorption. The result: crushing fatigue, brain fog, hair loss, and anemia that 18mg supplements simply cannot address.
B12 Damage Can Become Permanent
Without intrinsic factor from a full stomach, B12 absorption plummets. Nerve tingling, memory gaps, and numbness aren't just symptoms. They can become irreversible.
Your Bones Are Quietly Weakening
Calcium and Vitamin D absorption drop significantly after surgery. Bone density loss begins within months. Most patients don't catch it until a fracture forces the conversation.
"Just Tired" Is Not Normal
The fatigue, mood swings, and mental fog aren't a phase. They're your body signaling that critical micronutrients aren't reaching your cells. GLP-1 users eating 1,000 calories a day face the same shortfall.
Engineered for Altered Absorption
Titan wasn't built for normal digestion. Every dose, every form, every milligram is calibrated for the post-surgical and GLP-1-altered gut.
Clinical-Grade Iron at the Right Dose
45mg of chelated iron (Ferrous Bisglycinate). The exact amount the ASMBS recommends for at-risk bariatric patients. Not the 18mg you'll find in generic drugstore multivitamins. Chelated for superior absorption even with reduced stomach acid.
45 mg Iron · 250% DV · ASMBS AlignedHigh-Potency B-Complex for Nerve Protection
Therapeutic doses of B12, B1 (Thiamine), and Folate. The three nutrients most vulnerable after surgery. Not the token amounts designed for someone with a full stomach and normal absorption.
18mg Iron · 6mcg B12 · Generic forms · Designed for normal absorption
45mg Chelated Iron · 1000mcg B12 · Bioavailable forms · ASMBS doses
Fat-Soluble Vitamins in Absorbable Forms
Vitamins A, D, E, and K require fat for absorption, and your altered anatomy limits both fat intake and fat digestion. Titan uses water-miscible and bioavailable forms so these critical nutrients actually reach your bloodstream.

Bariatric Multivitamin with 45 mg Iron
Once-daily capsule · 90 count (3-month supply) · Replaces 4-6 daily supplements
45 mg Chelated Iron (Ferrous Bisglycinate)
The ASMBS-recommended dose in the most absorbable, stomach-friendly form. No nausea. No constipation. Designed for acid-reduced stomachs.
1,000 mcg Methylated B12 + Full B-Complex
Protects against the nerve damage, fatigue, and cognitive decline that strikes when B12 absorption is compromised post-surgery.
3,000 IU Vitamin D3 (Water-Miscible Form)
Your altered gut can't absorb standard fat-soluble vitamins efficiently. Water-miscible D3 bypasses the problem entirely.
One Capsule Replaces Your Entire Stack
Most bariatric brands require 2-4 chewables per day. Titan consolidates everything into a single once-daily capsule. Simpler routine, better compliance, fewer missed doses.
Up to 45% of bariatric surgery patients develop iron deficiency. ASMBS recommends 45 mg/day of iron for at-risk patients. Regular multivitamins provide less than half that amount.

Every Capsule, Clinically Dosed
No pixie-dusting. No token amounts. Every nutrient dosed to meet or exceed ASMBS post-operative guidelines.
Chelated Iron (Ferrous Bisglycinate)
The most bioavailable form of iron available, chelated for absorption even in acid-reduced stomachs. Gentle on the GI tract. No nausea, no constipation. At the full 45mg dose recommended by ASMBS for at-risk bariatric patients and menstruating women.
45 mg · 250% Daily ValueHigh-Potency B-Complex (B12, B1, Folate)
1,000mcg Methylcobalamin B12 for nerve protection and energy. 3mg Thiamine (B1) to prevent the neurological damage that hits silent and fast post-surgery. 800mcg methylated Folate for DNA synthesis and cell repair.

3,000 IU Vitamin D3 in water-miscible form because your altered gut can't absorb standard fat-soluble supplements efficiently. Paired with Vitamin A (5,000 IU), Vitamin E (15mg), and Vitamin K (120mcg) for immune function, bone density, and clotting support.

Nutritional recovery doesn't happen overnight. Here's what consistent daily supplementation looks like as your body rebuilds its stores.
Baseline Stabilization
Your body begins absorbing clinical-grade iron, B12, and D3. Many patients notice improved sleep quality and reduced headaches as thiamine levels stabilize. Chelated iron means no stomach upset.
Energy Returns
As iron stores rebuild and B12 reaches nerve tissue, the crushing afternoon fatigue starts to lift. Brain fog clears. You start feeling like yourself again.
Visible Changes
Hair shedding slows as ferritin recovers. Nail strength improves. Mood stabilizes as the full B-complex supports neurotransmitter production. Lab work should reflect measurable improvement.
Sustained Protection
Iron and D3 stores reach protective levels. Bone density loss decelerates. Your body has a genuine nutritional foundation. This is the long game: lifelong supplementation, lifelong protection.
What Our Customers Actually Say
From post-op patients to GLP-1 users. Real stories from people whose bodies demand more than a generic vitamin.
"My surgeon kept telling me my iron was too low and I was already taking another bariatric multi. Switched to Titan three months ago and my ferritin went from 12 to 38 at my last blood draw. One capsule, done. I wish I'd found this sooner."
"I've cycled through Bariatric Fusion, BariSlim, and Celebrate over three years. Multiple pills, chewables that taste like chalk, and my levels still kept dipping. Titan is one capsule. No taste, no hassle. My B12 and D are finally in range for the first time since surgery."
"I'm not post-surgery. I'm on Mounjaro and my doctor flagged low Vitamin D and iron at my 6-month check. She recommended a bariatric-grade multi because I'm eating so much less. Titan fit perfectly. The brain fog I blamed on the medication? Gone within a month."
"Giving it 4 stars because I'm only 7 weeks in and waiting for my next blood panel. But I will say the fatigue has improved noticeably and my hair isn't clogging the shower drain anymore. No stomach issues from the iron either, which surprised me. Will update after my 12-week labs."
Frequently Asked Questions
No. Regular multivitamins like Centrum or One-A-Day are formulated for people with normal digestive anatomy. After bariatric surgery, your stomach is smaller, acid production is reduced, and key absorption zones may be bypassed entirely. ASMBS guidelines recommend significantly higher doses of iron (45mg vs. 18mg), B12 (1,000mcg vs. 6mcg), and Vitamin D (3,000 IU vs. 600 IU) specifically because standard amounts aren't enough for your altered system.
Research increasingly suggests yes. A 2026 review published in Clinical Obesity found that GLP-1 medication users develop nutrient deficiencies, particularly in Vitamin D, iron, and B vitamins, because they're eating 30 to 50% less food. The deficiency profile closely mirrors post-bariatric surgery patients. A bariatric-grade multivitamin provides the higher doses needed when food intake alone can't cover your nutritional requirements.
45mg is the exact dose recommended by the American Society for Metabolic and Bariatric Surgery (ASMBS) for patients with a history of anemia or menstruating females. We use chelated iron (Ferrous Bisglycinate), which is gentler on the stomach and better absorbed than standard ferrous sulfate. Less GI discomfort, more iron reaching your bloodstream.
Yes. Iron and calcium compete for the same absorption pathways, which is why ASMBS recommends taking them at least 2 hours apart. Titan includes your full iron, B-complex, and fat-soluble vitamin needs in one capsule. Take your calcium citrate supplement separately at a different time of day for maximum absorption of both.
Most bariatric brands require 2 to 4 chewables or gummies per day. Titan is a once-daily capsule. Simpler to remember, easier to stay consistent. We also use chelated iron for superior absorption, methylated B-vitamins for better bioavailability, and water-miscible Vitamin D3. No sugar, no artificial sweeteners, no chalky chewable taste.
Most surgeons recommend beginning a bariatric multivitamin within the first few weeks post-surgery, once you can tolerate capsules. Check with your surgical team on exact timing. Once started, bariatric supplementation is a lifelong commitment. Your altered anatomy will always require higher nutrient doses regardless of how many years have passed.
Titan uses chelated iron (Ferrous Bisglycinate), which clinical studies show causes significantly less nausea, constipation, and GI distress than standard iron forms. Most customers report no stomach issues at all. If you have a sensitive stomach, take Titan with a small amount of food. As always, consult your healthcare provider before starting any new supplement.
We offer a 90-day, no-questions-asked money-back guarantee. If Titan doesn't meet your expectations for any reason, contact our support team for a full refund. We believe that strongly in what's inside every bottle.
