Menopause Stole Your Collagen. Here's How You Take It Back.

Your tendons haven't lost the ability to heal. They've lost the raw materials to do it with, the nutrients menopause quietly stops delivering. Stride+ puts them back where they belong.

Some Women Healed In Weeks. Others Waited Months.

I'm Sarah Mitchell, the founder of Halsten.

After thousands of women started using our light therapy, I started watching something closely in the results. Most were getting exactly what we'd hoped for: sleeping on their side again, walking without planning for it, telling us they felt like themselves for the first time in years.

But some women got there in weeks. Others took months to feel the same difference. Same twenty minutes a day. Same instructions. Different timelines.

That gap sent me back into the research, further than I'd gone before. I needed to know why.

What I found changed how I think about what a menopausal body needs to heal.

Diane Was One Of The Women Who Waited. Then She Wasn't.

Diane is 61. Five years of hip pain, three doctors, months of physical therapy, and cortisone shots that wore off faster each time.

She started her light therapy and did everything right: twenty minutes every morning, no days skipped. Six weeks in, she wondered out loud if her body was just too far gone.

It wasn't too far gone. It was underfed. Her tendon cells needed the raw material to answer the signal, not more time under the light.

I sent her the first bottle of what we now call Stride+, no charge: same routine, just one capsule added each morning.

She called back at week four. Three nights asleep on her side. Her dog's whole neighborhood loop, walked start to finish, for the first time in two years.

“Sarah,” she said. “It's finally working.”

Light Sends The Signal.
Your Body Still Has To Build.

Here's something most red light therapy companies never explain:

Light doesn't create collagen. No device can. What it does is flip a switch inside your tendon cells, a signal that says build new collagen, now.

That signal used to be enough. Before menopause, your body had all the materials on hand to answer it.

Not anymore.

Collagen is built from specific amino acids and minerals your cells assemble into new tendon fiber, and every one of them runs lower after menopause, because when estrogen drops, so does your body's ability to absorb and use them.

Picture a construction crew ready to rebuild your house, but the truck carrying the lumber never shows up. Day after day, they arrive, wait, and go home. That's what's happening inside a tendon getting the signal to rebuild with nothing to rebuild with.

Stride+ is the truck: the exact nutrients your cells need, in the ratios research points to, in a form the postmenopausal body can actually absorb. Used alongside your light therapy sessions, this is what closes the loop, the signal and the supply, arriving together, every day.

Why Taking Collagen Alone Doesn't Work.

If you've read that collagen supplements barely touch joint or tendon pain, you read something true. You were right to be skeptical.

Generic collagen powder is mostly wasted on tendons. Your stomach acid breaks it apart into random amino acids before it ever reaches the tissue that needs them, so the shake ends up doing more for your skin than your hip.

Stride+ isn't collagen. It's the specific nutrients and amino acids your tendon cells use to build their own, in ratios built for tendon repair and formulated for how the postmenopausal body actually absorbs them.

The difference isn't a better label on the same bottle. It's the difference between shipping your body finished furniture it has no use for, and shipping the lumber, the nails, and the blueprint it's actually been missing.

Deficient Or Not, You Get There Faster.

After Diane, we started offering Stride Plus to women whose results were already strong, women who didn't seem to be running short on anything at all.

Every one of them got there faster. Deeper relief. Better sleep, sooner.

Here's why. Your light therapy tells tendon cells to build collagen at four to five times their normal rate, more than a normal day's supply can keep up with. Your cells are working overtime, whether or not you're technically deficient.

Whichever category you're in, more material means faster relief, sooner sleep, and results you don't have to wait on.

Ninety Days. One Window. Don't Show Up Empty-Handed.

Tendons don't repair in days or weeks. Real structural change takes eight to twelve weeks of consistent treatment: call it the ninety-day window.

That's the stretch where everything changes, or doesn't. Start Stride Plus the same day your light therapy begins, and stay on it the full ninety days, so your body never runs out of material mid-repair.

Days 1-30:

Collagen production ramps up. Mornings start feeling less stiff.

Days 30-60:

Structural change begins. Sleep gets easier, and you stop bracing before you move.

Days 60-90:

Fibers strengthen and align. This is the window where it stops feeling lucky and starts feeling permanent.

It's Finally Working

Verified Purchase

I'd used Stride for six weeks with barely any change and honestly started to think it wasn't going to work for me. I emailed Halsten asking why, and someone explained the ingredient gap and pointed me to Stride Plus. Three weeks later I slept through the night on my side for the first time in over a year.

I Didn't Think I Needed It

Stride was already working for me, so I almost skipped this. Glad I didn't. My results just kept coming faster once I added it in. Wish I'd started both on day one.

"But What If..."

"What if I Don't Think I'm Deficient?"

Most postmenopausal women are, whether or not they feel it day to day. But even women whose results were already strong saw them come faster with Stride Plus. There isn't a version of using Stride where extra materials don't help.

“What if I Already Take a Multivitamin or a Collagen Supplement?”

Multivitamins aren't formulated for the specific ratios tendon repair calls for, and generic collagen doesn't survive digestion intact. Stride Plus is built specifically for what's happening in your tendons during Stride sessions, not general wellness maintenance.

“What if I Only Want to Try One Month?”

You can. The single bottle option lets you try it for thirty days. Most women choose the 90-Day Supply because that's the window the research points to for lasting structural change, but starting smaller is better than not starting.

“What if It Doesn't Work for Me?”

Then you risk nothing. Same 90-day money-back guarantee as Stride. If you don't see the difference, send back what's left and we refund every penny.

“What if I Already Ordered Stride and Skipped This?”

You can still add it. Reach out and we'll get Stride Plus added to your protocol so it arrives close to when your Stride does.

Use It For 90 Days. If Your Results Don't Match What You Were Promised, Get Every Penny Back.

Take Stride+ every day alongside your Stride sessions for the full ninety days. Give your body everything it needs to do what the light therapy is asking of it.

If you don't feel a real difference:

Better sleep

Faster progress

Deeper relief

...then we don't want your money.

Keep what's left, and we'll refund every penny. No forms, no hoops.

Your Stride is already doing its job. Make sure your body can do its job too.

Questions from Women Just Like You

What exactly is in stride plus?

A blend of the specific amino acids and cofactors tendon cells use to build collagen, including vitamin C, copper, manganese, glycine, lysine, and proline, in ratios formulated for postmenopausal collagen synthesis.

How is this different from a collagen supplement?

Collagen powder is broken down by digestion before it reaches your tendons. Stride Plus delivers the specific building blocks your cells use to make their own collagen, in a form designed to be absorbed and used, not the collagen itself.

Do I need to use it with stride, or can I take it on its own?

Stride Plus is formulated to work alongside Stride sessions, supplying the materials your cells need while the light therapy is actively signaling them to rebuild. It's also meant to continue after your ninety-day protocol, to help maintain your results and keep your collagen levels where they need to be.

When will I notice a difference?

Most women on the combined protocol notice initial changes within the first few weeks, with the deeper structural changes happening across the full 8–12 week window.

Is it safe to take daily?

Yes. Stride Plus is formulated from nutrients and amino acids already found in a healthy diet, at levels designed for daily use across the full 90-day protocol.

Does it ship separately from my stride?

No. It ships in the same box as your Stride order, with no additional shipping cost.
