How I got my strength back at 61
I Had to Set the Dog Food Bag Down Halfway to the Trunk.
I walk every morning. I thought I was doing everything right.
CBy Carol M. · Updated Oct 2026 · 5 min read
The parking lot. A Saturday in September.
Forty pounds. Same bag of dog food I've bought every month for six years, ever since we brought Buster home.
That Saturday I got it about halfway up to the trunk and felt my lower back say no. So I set it down on the edge of the cart and just stood there, holding it in place.
A young man two spots over called out and asked if I needed a hand. I said no thank you, I've got it.
I did get it in. Then I sat in the driver's seat for a good minute before I turned the key.
It wasn't my back
At home I did what I always do. I looked it up.
My back was fine. What I'd been losing, slowly and without noticing, was muscle. And the thing that surprised me most: researchers who study aging say people our age likely need more protein each day than younger adults, not less.1
Toast and coffee for breakfast. A salad at lunch. Chicken at dinner if I felt like cooking. I would have told you I ate well. I was probably short on protein most days.
Five things on my shelf, and I used maybe half of them
My pantry shelf in September
Warehouse-store whey
Collagen powder
Bone broth cartons
Protein bars
A probiotic I kept forgetting
Two extra eggs a day
None of it was a bad idea. But I was buying five different things and using maybe half of them. The whey sat in my stomach like wet cement until noon, so I quit it after a week.
"Carol, I stopped buying all of that. I use one scoop of one thing. Take mine home and try it for a month."
Joanne, from my Tuesday morning pickleball group
Joanne is 66 and still runs me ragged at the kitchen line. So I listened.
Her tub was StemCell Protein. I read the label standing in her kitchen, and a few things got my attention.
One scoop of one thing. I gave it the month Joanne asked for. Here's what I wrote down.
My first 30 days
Day 1
One scoop of chocolate in a mason jar with cold milk. Shook it like salad dressing. It tasted like a chocolate shake, not chalk, and there was no wet cement sitting in my stomach at lunch.
Week 2
Pickleball with Joanne on Tuesday. I've started putting the vanilla in my morning coffee some days. My knees didn't complain the next morning the way they usually do.
Day 30
Saturday. Same store, same bag. Knees bent, back straight, into the trunk in one go. The young man wasn't there this time. I almost wished he was.
One person's experience. Individual results vary.
Why this one didn't end up on the shelf with the others
It's one thing. One scoop instead of five half-used containers on the shelf.
It's easy on my stomach. The AB22 probiotic is there to support digestion, and I could tell the difference from the whey.
It was made for my age. Made especially to help people over 60 supplement their protein needs. No flexing man on the label.
I actually like it. Chocolate in cold milk, vanilla in coffee. If I didn't like it, I'd have quit by week two like everything else.
Turns out Joanne and I weren't the only ones
Before I ordered my own tub, I looked up what other people said. Longevity Rx surveyed its members after 30 days:
84%felt stronger and more physically resilient*
81%had less bloating and improved digestion*
78%noticed better joint comfort or flexibility*
Notes from other customers
"I could notice the difference in my strength."
★★★★★
"StemCell Protein has been a major part of my health transformation, providing an increase in foundational proteins as well as flexibility in how I am able to utilize it; pour it in coffee or an afternoon smoothie. In the matter of a week or two, I could notice the difference in my strength and recovery."
★★★★★
"I've tried scores of protein powders over the years and this one is truly a standout. The vanilla flavor is light and delicious without any strange, chalky, meaty, or overly-sweet aftertaste that so many others have. It blends effortlessly into smoothies and mixes beautifully into recipes, making it incredibly easy to use every day."
★★★★★
"I like the fact that I can consume protein without always having to eat a meal by simply adding StemCell Protein powder to a smoothie or overnight oats. Both flavors, chocolate and vanilla, have a pleasant taste. I trust the brand and so should you! Give it a try. I think you'll like it!"

Questions I had, too
How do I take it?
One scoop a day. I shake it into cold milk, but it also mixes into water, coffee or a smoothie.
Will it sit heavy like other protein shakes?
That was my worry after the whey. StemCell Protein includes Bacillus subtilis AB22, a probiotic that supports digestion, and 81% of members surveyed reported less bloating and improved digestion.*
What does it taste like?
Chocolate or vanilla. No chalky aftertaste. It's caffeine-free, so it won't stack on top of your morning coffee.
Is this a subscription?
No. This is a one-time order with 25% off using code Protein25. You won't be signed up for anything.
I take prescription medication. Is it okay?
Check with your doctor before starting any new supplement, especially if you take prescription medication or have a medical condition.
What if it's not for me?
You have 30 days. If it's not for you, Longevity Rx will refund your order.
Last Saturday
Buster's bag again. I bent my knees, lifted, and set it in the trunk. I didn't think about it until I was already pulling out of the lot.
That's the part I want you to hear. Not that I'm stronger than I was at 40. That I stopped thinking about it.
One scoop. One month. That's what Joanne asked of me, and it's all I'd ask of you.
P.S. If you've ever set something down halfway because your back said no, start here. StemCell Protein is 25% off with code Protein25, and you have 30 days to decide.
