✓ Supports daily comfort, restful sleep, and overall quality of life as part of a healthy routine
Methylcobalamin (Active B12) — 5,000mcg
The only form of B12 clinically shown to rebuild damaged myelin sheaths.
Methylcobalamin is the bioactive form of B12 your nerves can use immediately — no conversion required. It donates methyl groups your body uses to rebuild the protective insulation around damaged nerve fibers, and has been shown in clinical studies to improve nerve conduction velocity and reduce neuropathic pain scores over 12–16 weeks.
Most supplements use cyanocobalamin — a synthetic form that requires conversion your body, especially if diabetic, often can't complete reliably.
Folate (as Folic Acid) — 400mcg DFE
Works alongside B12 to lower homocysteine — an inflammatory compound directly linked to nerve deterioration. Supports healthy neurotransmitter synthesis and proper nerve cell communication.
Niacinamide (B3) — 16mg
Supports cellular energy production inside nerve cells and promotes healthy blood flow to the extremities. Niacinamide form is used specifically to avoid the flushing associated with standard niacin.
Pyridoxine HCl (B6) — 3.4mg
Essential for neurotransmitter synthesis and reducing inflammation around nerve tissue. Supports the formation of myelin basic protein — a key structural component of healthy nerve fiber insulation.
Thiamine Mononitrate (B1) — 2.4mg
Supports nerve energy metabolism and helps protect nerve cells from glucose-related damage — particularly important for diabetics experiencing peripheral neuropathy.
Sublingual Liquid Delivery
Absorbed in 60–90 seconds — bypasses digestion entirely Delivered as a liquid drop under the tongue, Nuvel absorbs directly through the sublingual mucosa straight into your bloodstream. Metformin can't block it. Low intrinsic factor can't stop it. No stomach acid destroys it. It reaches your nerves fast — every single dose.
✓ No artificial flavors or sweeteners
✓ No preservatives
✓ Non-GMO
✓ Gluten-free
✓ Soy-free
✓ Dairy-free
✓ Sugar-free
✓ No fillers
✓ GMP Certified
1. Place 1½ droppers under your tongue — Hold 60–90 seconds before swallowing
2. Take daily, same time each day — Consistency is what allows nerve repair to compound
3. Give it 3–4 weeks — Nerve repair happens at the cellular level and builds gradually
4. Continue for long-term support — Results compound the longer you stay consistent
Most customers notice real changes within 7–14 days — reduced tingling, better sleep, more feeling in the feet and hands. For full nerve repair benefit, consistent use for 4–6 weeks delivers the complete transformation.
Because Nuvel works at the nerve cell level, the results don't just appear — they last.

Stop Taking 'Dead' Vitamins
If you’ve been taking B-Complex pills but still feel the ”zaps,” the fatigue, and the brain fog... it’s not in your head. And it’s not your fault.
The problem is that most store-bought vitamins use inactive, synthetic forms that your body has to work hard to convert. Here at Nuvel we solve that problem!
What Customers Tell Us — Week by Week
Days 1–5: Early Settling In
Many customers describe a gradual sense of settling — burning sensations feeling less disruptive, and the intensity of tingling beginning to ease as the body begins absorbing active B-vitamins.
Most common first feedback: "feels calmer"Week 2: Customers Notice a Shift
By week two, many customers report walking more comfortably and sleeping with fewer nighttime disruptions. Buzzing and vibrational sensations are commonly described as more manageable.
Sleep quality is the most-reported improvement at week 2Weeks 3–4: The Most Common "Turning Point"
Weeks three and four are when customers most frequently say they notice a meaningful difference. Numbness begins to feel less constant, and daily tasks feel more comfortable. Most customers describe this as the moment it "clicked."
Weeks 3–4 are the most reported turning pointWeeks 6–8: Compounding Comfort
Customers who stay consistent through weeks six to eight most frequently describe improvements in daily mobility, foot and hand comfort, and overall wellbeing. The sublingual format supports ongoing B-vitamin replenishment every dose.
Consistency is the top factor in long-term satisfactionDay 90+: Sustained Daily Support

Why milions of people are recommending Nuvel
Excellent 4.8 / 5
-
Helped with my B12!
"My doctor told me Metformin had been depleting my B12 for years without me knowing. By the time I found out, the numbness in my hands and feet was already bad. Six weeks on Nuvel and my last labs showed my B12 levels finally back in normal range. The numbness is about 80% better."
-
Can finally sleep!
"I was waking up at 2am every single night from the burning in my feet. It was ruining my sleep and my entire next day. Two weeks into Nuvel and I'm sleeping through the night again. My wife noticed the difference before I even said anything."
-
Exceeded my expectations
"I spent three years on gabapentin and all it did was make me foggy and tired. My doctor kept upping the dose but the neuropathy never got better.
-
My wife's happiest day
"The weakness in my legs was getting to the point where I didn't trust myself on stairs. My balance was off and I was starting to rely on my wife more than I wanted to admit. After about a month on Nuvel I'm walking more confidently and I've got my independence back. That means everything at my age."
-
Thank God I found this!
"The constant tingling in my feet has almost completely disappeared after about 3 weeks. I'd been dealing with that buzzing, pins-and-needles feeling for years and just accepted it as my new normal. Nuvel is the first thing that's actually changed that."

Most B12 supplements are oral pills with only 1-2% absorption.
If you take Metformin, acid reducers (PPIs), or you're over 50, your stomach struggles to absorb B12 from pills. You lose a protein called "Intrinsic Factor."
Sublingual delivery bypasses your stomach entirely. Nutrients absorb under your tongue → bloodstream → nerves in 60 seconds.
It's not that B12 doesn't work. Pills just never reached your nerves effectively.
Blood tests only measure B12 in your bloodstream — not whether it's reaching your nerve cells.
You can have "normal" blood levels but still experience symptoms because your stomach can't absorb oral B12 effectively or the B12 isn't crossing into nerve tissue.
Yes. Sublingual delivery bypasses your digestive system completely. You don't need strong stomach acid to absorb it.

Drugstore formulas typically use synthetic forms your body has to convert.
