Why Do Some 70-Year-Olds Have More Energy Than People Half Their Age?
Researchers say part of the answer comes down to one molecule your body produces less of every year after 40 - and a simple melt-on-your-tongue method designed to support it.

The Question More Americans Over 60 Are Asking
Walk into any gym, park, or pickleball court in America and you’ll notice something strange.
Some people in their 60s and 70s move with the energy of someone decades younger. They take the stairs without thinking twice. Their hands and feet stay warm. They finish the day with energy to spare.
Meanwhile, others the same age – sometimes younger – feel drained by mid-afternoon, get winded on a single flight of stairs, and can’t remember the last time they woke up feeling refreshed.
Same age. Completely different bodies. Why?
The Invisible Decline Most People Never Hear About
Scientists have been studying a molecule called nitric oxide for decades. The research behind it was considered so important that it was recognized with a Nobel Prize in Medicine in 1998.
Nitric oxide acts as a natural signal that helps blood vessels relax and widen, supporting healthy circulation throughout the body – to your muscles, your brain, your hands and feet, everywhere.
Here’s the problem: research shows the body’s natural nitric oxide production declines significantly with age. By the time many people reach their 70s, they may be producing only a fraction of what they did in their 20s.
Less nitric oxide can mean circulation that isn’t what it used to be. And for many older adults, that can show up as low energy, cold hands and feet, and feeling older than they’d like.
The Nutrients Researchers Keep Coming Back To
The good news: nitric oxide production can be supported through nutrition. Three ingredients stand out in the research:
Beet Root – one of nature’s richest sources of dietary nitrates, which the body uses to produce nitric oxide. Beets have become one of the most studied circulation foods in sports and aging research.
L-Citrulline – an amino acid the body converts into L-arginine, the raw material for nitric oxide. Studies suggest citrulline is more effective at raising arginine levels than taking arginine directly, because it isn’t broken down in digestion.
Hawthorn – a traditional botanical studied for its role in supporting the endothelium, the thin lining inside blood vessels where nitric oxide is made.
Why a Lozenge Instead of a Pill
Here’s a detail most people miss: part of nitric oxide conversion begins in the mouth, with the help of natural oral bacteria. That’s one reason a lozenge that dissolves on the tongue is an interesting delivery method – it works with that process instead of skipping it.
That’s the idea behind CircO2, a nitric oxide support formula from Advanced Bionutritionals that combines beet root, L-citrulline, hawthorn, and supporting nutrients in one quick-dissolve tablet.
No pills to swallow. No powders to mix. One tablet a day melts on your tongue.
It was formulated specifically for adults over 50 – not for bodybuilders or athletes.
