Small Longevity Breakthrough #1: Omega-3, Vitamin D and Exercise

Over the past few years we've seen a lot of interesting longevity research. Most of it isn't about living to 150 or reversing aging overnight. Instead, it's made up of small steps that slowly move the field forward.

One study that really caught my attention looked at something surprisingly simple: omega-3, vitamin D and regular exercise.

Researchers followed 777 older adults for three years. They measured biological aging using epigenetic clocks, which estimate biological age based on DNA methylation rather than your birth date.

The results weren't dramatic, but they were real.

People taking omega-3 showed a small slowing of biological aging, and the combination of omega-3, vitamin D and exercise appeared to produce an even greater effect. Depending on the epigenetic clock used, the difference was roughly equivalent to slowing biological aging by about 3 to 4 months over the course of three years.

That probably won't make headlines.

But maybe that's exactly why it's important.

Not every breakthrough in longevity will look like a miracle. Sometimes progress comes from small improvements that are measurable, repeatable and tested in real people.

There are several other studies and technologies I'd love to discuss next, including:

• ER-100 and the first human cellular reprogramming trial.
• Senolytics and the idea of removing senescent cells.
• AI helping design therapies for aging.
• Epigenetic clocks and how we actually measure biological age.

Which one would you want to dive into next?

Exercise Motivation Over 60

Hello!

I am a PhD Candidate at the University of Oklahoma in the Department of Education. I am currently working toward completing my dissertation, which seeks to gain insight into ways in which individuals are motivated to engage in exercise, sports, and physical activity. I am particularly interested in the experiences of those ages 60 and older.

I am asking if you would participate in this project. If you are 18 years of age or older, you may participate. Your participation will involve completing an online survey, which is expected to take approximately 20-25 minutes. Participation is voluntary, and no identifying information is requested in the primary survey. At the end of the survey, you may choose to be redirected to a different link to be entered into a random drawing for one of three $25 Amazon gift cards.

If you choose not to participate, you will not be penalized or lose any benefits or services. If you would like to participate, please click the following link and complete the survey by August 30, 2026. If you know of other individuals who may be interested in participating in this study, you are welcome to forward this link to them.

New research has found breaking-up periods of prolonged sedentary behaviour with light physical activity every day could reduce the risk of cancer death by 12%. Data shows that sitting for more than 30 minutes at a time is particularly linked to a higher risk of cancer.

Scientists discover a surprising link between vitamin C and brain health

A study of more than 2,000 older adults found that lower vitamin C levels were linked to smaller gray matter volume and reduced connectivity within important brain networks

Flex 😁

For the last 6+ months, I’ve been doing a 16 kg farmer’s carry to the stop sign at my gym 4-5 times a week.  This is about 150 yards, there and back. 

I could do the 16 kg without stopping. I would occasionally do a 20kg  but was discouraged because I had to put it down at the top at the stop sign and sometimes halfway back.

The gym had a June challenge of carrying 100%, 75% or 50% of your body weight via Farmers Carry for 120 yards every day this month.  
I decided to do 20kg (x2 = half my weight) to the stop sign and back and also one handed 28kg, 60 yards left hand, 60 yards right hand, inside the gym.  To my delight, I’m stronger. F’g duh!!!

Although I still have to stop at least once with these weights,  I am no longer discouraged. This is all thanks to the challenge. Don’t let your mind beat you my friends!

Here's the secret to not losing muscle and strength as you get older

l made this post in the aging parents sub and l got banned for it. l personally don't see anything wrong with it, so if there's an issue, mods l would prefer a warning and correction, not a ban from nowhere.

I'm a certified geriatric medical doctor, and l also volunteer to take care of older patients in my free time. Just wanted to let you know that a lot of muscle loss and loss of strength is avoidable, and you can still be strong in your old age. I'm going to try to explain the analogy in the simplest way possible. Forgive me if it sounds dumb.

Our bodies are like a Lego castle, and muscles are made from protein Lego bricks. Our bodies need a constant reminder to keep those blocks together. When people get older, they usually stop lifting heavy things or challenging their bodies.

But without the hard work of pushing or pulling against weight, like doing squats out of a chair or using stretchy bands, the body thinks you don't need those muscles anymore and starts throwing the bricks away.

At the same time, older people need to eat more protein, because their bodies waste a lot of those proteins and do not turn them into the amino acids efficiently needed to make muscle. But you know, a lot of older people don't like protein-heavy meals; they prefer tea, toast, etc. Without new Lego bricks coming in from food, the body gets desperate for energy and actually tears down its own muscles to burn them as firewood just to stay alive.

So doing nothing will melt the muscle and make them weaker over time. To stop this, make sure you do some strength exercises; it doesn't have to be intensive, just enough to remind your body not to break down those muscles. Also, make sure you are eating enough easy-to-digest protein bricks every single day.

l hope this does not sound like a water-is-wet analogy. Feel free to ask questions, l will be happy to answer.
