Dr. Margaret Chen, Co-Founder
"I always recommend a sublingual B-complex for my neuropathy patients, especially those over 40 or on metformin. ThryveLabs combines B1, B6, and B12 in their active forms. We call it the 'Neurotropic Trinity'. It's what my research proved works best to support nerve regeneration. The sublingual delivery bypasses digestive unlike oral pills, giving patients the consistent nerve support and relief they've been searching for."
Neuropathy will become PERMANENT if you don’t stop it now
If you're dealing with burning feet at 3am, tingling that won't stop, or numbness spreading up your legs, you're fighting nerve damage that has a biological point of no return. Research shows once 50% of your nerve fibers are damaged, regeneration becomes nearly impossible. Patients who intervene within 2 years have an 85% reversal rate. After 5 years? Just 23%.
Here's why nothing has worked: Your stomach acid destroys 98% of oral B12 pills before they reach your bloodstream. You get temporary relief for 1-2 weeks, then the burning comes back stronger, often spreading to new areas.
ThryveLabs bypasses your digestive system entirely, delivering the complete B1+B6+B12 "Nerve Trinity" directly into your bloodstream. Ensuring your nerves get the exact nutrients they need to regenerate before it's too late.

For months, burning feet woke me up at 3 AM like clockwork. After three weeks on ThryveLabs, I'm sleeping through the entire night. I wake up actually rested for the first time in forever.

The stabbing pain in my feet made sleep impossible. I started these drops and within two weeks, I was falling asleep without the constant tingling keeping me awake. I didn't realize how exhausted I was until I could finally rest.

I'd lost all hope—the pain made me not want to get out of bed. ThryveLabs gave me my first real improvement in two years. I'm starting to feel like myself again, and that's everything.

20 years, ONE obsession, ONE product.
For decades, I watched my patients suffer. Doctors kept prescribing gabapentin that turned them into zombies without fixing the root problem. So I dedicated my career to studying one thing: how to actually REPAIR damaged nerves. That's why I formulated ThryveLabs.
VitaminB12
+
Rebuilds the protective myelin sheath around your nerves. It's the insulation that gets stripped away in neuropathy, causing burning, tingling, and numbness.
VitaminB6
+
Produces the neurotransmitters your nerves need to communicate properly with your brain and muscles, stopping the "pins and needles" misfires.
VitaminB1
+
Powers your nerve cells with energy and acts as an antioxidant shield, protecting them from further degeneration.

FAQ
Find answers to common questions about our products, shipping, returns, and more.
I've tried B12 supplements before and they didn't work. What makes this different?
+
Most B12 pills use cyanocobalamin (synthetic form) that your body has to convert, and if you're over 50 or on metformin, your stomach acid destroys 98% before absorption. ThryveLabs uses methylcobalamin (active form) delivered sublingually—bypassing your digestive system entirely and going straight into your bloodstream. Plus, we include B1 and B6, which research shows nerves need to actually regenerate.
How do I know it's not too late? What if my nerve damage is already permanent?
+
Studies show that patients who intervene within the first 2 years have an 85% reversal rate, and even long-term deficiencies can improve with proper B-vitamin support. If you're still experiencing symptoms (burning, tingling, numbness), that means your nerves are still alive and signaling—they just need the right nutrients to repair. Our 30-day money-back guarantee means there's no risk in trying.
This seems expensive. Why not just buy cheap B12 pills at the store?
+
Cheap B12 pills use the wrong form (cyanocobalamin), wrong dose (usually 500mcg maintenance instead of 5000mcg therapeutic), and wrong delivery method (pills your stomach can't absorb). You're not paying for vitamins—you're paying for nerve regeneration and your independence back. What's the cost of gabapentin side effects, physical therapy that doesn't work, or ending up with permanent damage?
Will this actually work for MY specific case? My situation might be different.
+
Over 10000 customers with your exact symptoms, burning feet at night, tingling hands, numbness from metformin, diabetic neuropathy, have seen measurable improvement. Peripheral neuropathy from B12 deficiency responds to proper supplementation regardless of your specific situation. That's why we offer a 30-day guarantee. You either see improvement or get your money back.
How long before I see results?
+
Most customers notice improvement within 1-4 weeks. Some experience better sleep within the first week. Nerve repair takes time, this isn't a painkiller that masks symptoms. We're addressing the root cause, which means real, lasting improvement but not overnight miracles.
Is this safe to take with my current medications?
+
Always consult your healthcare provider before use if you are pregnant, nursing, taking medications, or have a medical condition.
B-vitamins are safe and often recommended alongside medications. In fact, if you're on metformin, PPIs, or other medications that deplete B12, supplementation is especially important. Our formula uses doses within safe, well-studied ranges. However, we always recommend showing the supplement facts to your doctor, especially if you're on blood thinners or have kidney issues.
