I take four of them. Fish oil, vitamin D, magnesium, and one my daughter put in the cart.

So this is not a lecture. It is arithmetic about a shelf I stand in front of too.

Two federal surveys count what this cohort actually does about getting older. Set them beside each other and the aisle explains itself.

 

Three quarters of us buy something in a bottle. Fifteen in a hundred do the walking and the lifting both. Same cohort. Same goal.

Every dollar of the first figure comes out of your own pocket. No claim form, no card, no argument with anybody.

The second one costs a pair of shoes and two afternoons of your week.

That is the shape of the whole longevity aisle. The part that can be sold is the part that grows.

In every aisle behind this one, the calendar does the selling.

A bottle carries a barcode, a margin, a refill date, and a subscribe button. Each one of those is a reason for somebody to build a company around it.

Two sets of squats carry none of that. There is nothing there to build a company on.

The money sits one step behind the label. Most supplement brands do not own a factory.

They buy from a contract manufacturer. A plant that blends the powder, presses the capsules, and prints somebody else’s name on the bottle.

One plant runs forty brands. The brands fight each other for the shelf. The plant gets paid either way.

Where the cohort’s money sits this quarter, and the aisle it is walking into next.

That business has a ceiling, and it is a real one. The category rests on how people feel rather than on what a trial showed. One ingredient scare can empty a line for a year.

Regulation can move. A large retailer deciding to make its own squeezes the price overnight.

The other route has a catch too. Fifteen percent is a low number for a reason. Two sessions a week is easy to say and hard to keep through a bad knee and a long February.

The arithmetic

Share of adults age 60 and over who used any dietary supplement in the past 30 days, 75.9 percent: National Center for Health Statistics, Data Brief 561, May 2026, from NHANES August 2021 to August 2023. Share of adults 65 and over meeting the federal guidelines for both aerobic and muscle-strengthening activity, 15.5 percent in 2024: National Health Interview Survey, reported through Healthy People 2030; the same measure read 13.9 percent in 2022 in National Health Statistics Reports 215. Share of men 65 and over meeting the muscle-strengthening guideline alone, 22 percent: National Health Interview Survey 2020. The four bottles on my counter are mine, and the monthly cost is my own arithmetic rather than a national figure.

 

I will keep taking the four. They run me about forty dollars a month, and I have made my peace with that. The other route is already on the calendar for Tuesday and Friday. Only one of those two has a company behind it that needs me to keep going. Watch which one gets advertised to you this winter.
