How Our Body Ages Over Time

what experts say

As we age, our cells become less efficient at producing energy, repairing damage, and maintaining structure. Collagen declines, mitochondria weaken, and telomeres — the protective caps on our DNA — shorten, reducing our cells’ ability to renew.

These biological changes affect everything from joints and skin to memory, metabolism, and immune response. Inflammation and oxidative stress accelerate these effects, including telomere erosion. Researchers are gaining new insights every day into simple daily habits that can slow these processes and help preserve a healthy, resilient body.

Healthy aging isn’t just about adding years to life — it’s about feeling strong, clear-headed, and capable for as many of those years as possible.

FAQ

There’s no perfect age to start — because healthy aging begins long before the signs show. The earlier you start building daily habits that support your energy, mobility, and cellular repair, the better. But even if you’re starting in your 50s or later, small changes still make a measurable difference.

Options like NMN, spermidine, Calcium AKG, resveratrol, collagen, quercetin, and vitamin D may support repair, energy metabolism, inflammation balance, and overall resilience. These nutrients are studied for their roles in healthy aging — including mitochondrial function, autophagy, telomere protection, bone strength, and longevity. Find them all here: Shop Healthy Aging

You can’t stop aging, but you can influence how it affects your body — and even reverse aspects of it. Research shows that habits like sleep, strength training, and smart supplementation play a role in how we age. In fact, some experts believe you can reduce your biological age through consistent lifestyle changes. Check Bryan Johnson’s blog post here: Bryan Johnson Blueprint protocol

Chronological age is the number on your birthday. Biological age reflects how well your body is functioning — and it can be influenced.

Most people tolerate them well. Some may notice mild digestive symptoms. There are many types of longevity supplements, each with different functions in the body — from supporting energy production and cellular repair to immune balance and bone strength. Always follow recommended dosages and check with your doctor if in doubt.
