1. Your Brain Is Starving for the Fuel It Needs to Make Serotonin

If your head feels like it's "stuffed with cottonballs" and your body feels like "cement," you're not imagining it.

Up to 40% of people have a genetic variant (called MTHFR) that prevents their body from converting the "folic acid" in food and vitamins into the active form their brain actually needs: L-Methylfolate.

Without L-Methylfolate, your brain can't make serotonin or dopamine—no matter how many antidepressants you take. This isn't a personal failing. It's a mechanical problem with a mechanical solution.

2. SSRIs Don't Make Serotonin—They Just Recycle What's Already There

You've tried the antidepressants. Prozac, Zoloft, Lexapro. They worked for a while, then they "fizzled out" or stopped working altogether.

Here's what your doctor didn't tell you: SSRIs don't make serotonin. They just help you use the serotonin that's already in your brain.

But if your brain is starved of L-Methylfolate—the raw material it needs to make serotonin in the first place—then no amount of medication will work. You're trying to drive a car with no fuel.

3. The "Synthetic Folic Acid" in Your Food Is Blocking Your Brain's Receptors

Since the 1990s, the U.S. has been adding synthetic folic acid to bread, cereals, and vitamins. It was meant to be helpful. But for people with the MTHFR gene variant, it's making things worse.

Your body can't convert this synthetic form. It just builds up like a toxin, blocking the receptors for the real, usable folate your brain is desperate for. This is why antidepressants can't work—the "docking station" for brain fuel is clogged.

The solution? Body-ready L-Methylfolate that requires no conversion. It's the form your brain can actually use—immediately.

4. The 1mg Dose You Tried Wasn't Strong Enough for Treatment-Resistant Depression

You may have already tried L-Methylfolate pills. You bought the 1mg or 5mg bottle from Amazon. You took it for weeks. And you "didn't feel anything."

That's because those doses are for daily wellness—not for persistent, treatment-resistant symptoms like the ones you're experiencing.

Clinical studies on people with Major Depressive Disorder who failed SSRIs found that 15mg per day was the effective dose. That's the exact dose in Neupril. This isn't a "wellness" supplement. It's a clinical-strength solution for people who need real results.

5. High-Dose Methylfolate Without B12 Creates Anxiety and Side Effects

Here's where most methylfolate supplements fail—and why you may have quit taking them: they give you the gas (L-Methylfolate) but not the spark plug (Methyl-B12).

Without active B12, high-dose methylfolate can cause what's called the "folate trap"—leading to anxiety, headaches, and irritability. That's why people say, "It made me feel worse." They gave up on the solution that could have worked.

Neupril's formula is complete. It includes both the 15mg L-Methylfolate and the Methyl-B12 your body needs to use it safely and effectively. This is the balanced, synergistic formula your brain has been waiting for.

"My antidepressant finally works now"

I've been on Lexapro for two years and it helped at first but then just stopped working. My doctor added Neupril and within three weeks the difference was incredible. I finally feel like my medication is actually doing something again!

- Angela D.

"The missing piece I didn't know about"

After trying four different antidepressants with minimal results, I learned about the MTHFR gene and L-Methylfolate. I've been taking Neupril for five weeks and it's like someone turned the lights back on. My brain finally has what it needs to make serotonin.

- Stephanie W.

"No more cement feeling"

The heaviness and brain fog that my antidepressant couldn't touch is finally lifting. Three weeks on Neupril and I can think clearly again. My body doesn't feel like it weighs a thousand pounds anymore. This is what I've been missing!

- Emily C.

"15mg made all the difference"

I tried a low dose methylfolate before with zero results. Neupril's clinical strength formula actually works. My depression symptoms that wouldn't respond to anything else are finally improving. Wish my doctor had told me about this years ago!

- Jessica N.

"No anxiety like standalone methylfolate gave me"

I tried high dose methylfolate once before and it made me so anxious I had to stop. Neupril's formula with the B12 is completely different. No side effects, just steady improvement in my mood and energy. Finally found something that works with my body!

- Vanessa P.

"My SSRI wasn't enough on its own"

I've been on Zoloft for three years and plateaued about a year ago. Adding Neupril was the breakthrough I needed. My energy is back, my focus is sharp, and I feel like myself again. It's like my medication finally has the fuel it needs to work.
