We’ve all experienced it.
You’re in the middle of a conversation, trying to recall a word or a name, and suddenly it slips away. You know it - you can almost feel it - but it just won’t come out.
These “tip of the tongue” moments can feel small, but when they start happening more often, they become more noticeable. Over time, they can chip away at your confidence and make you wonder what’s happening to your memory and your ageing brain.
For many people, this isn’t just about memory - it’s about clarity, confidence, and feeling in control during everyday conversations.
What’s Really Happening Inside the Brain
The brain is one of the most energy-demanding organs in the body. It relies on a constant and responsive supply of oxygen and nutrients to function properly.
This supply is delivered through a network of blood vessels, including very small vessels called capillaries, which deliver nutrients directly to brain cells.
As we age, this system can gradually change:
- Capillary networks may become less dense
- Blood vessels may become less responsive
- The delivery of oxygen and nutrients may become less efficient
- This doesn’t mean something is “wrong” - but it does mean the brain may not always get what it needs as quickly as it used to, especially during moments that require fast recall.
Why Blood Vessel Responsiveness Matters
Healthy blood vessels are not static - they constantly adjust.
They widen and narrow depending on what the body needs. This allows blood flow to increase when certain areas of the brain are active.
When this responsiveness becomes less efficient:
- The brain may respond more slowly during conversations
- Recall can feel delayed
- Mental sharpness may fluctuate
- This is why those small pauses or forgotten words can become more noticeable over time.
The Role of IGF-1: Your Brain’s Quiet Helper
Behind the scenes, a hormone called IGF-1 (Insulin-like Growth Factor-1) helps keep this system running smoothly. It acts as part of the body’s “support system” for both the brain and blood vessels as we age.
IGF-1 helps blood vessels:
Widen and narrow when needed, so more blood can reach active areas of the brain
Maintain a smooth and resilient inner lining for efficient blood flow
Repair and renew over time, which becomes increasingly important with age
It also supports the tiny capillaries that sit close to brain cells, helping them remain stable rather than breaking down.
When these small vessels are healthy and responsive, the brain is better able to receive the oxygen and nutrients it needs for memory, focus, and clear thinking.
Supporting Balance and Brain Function: Where cGP Fits In
While these changes are a natural part of ageing, the body has systems in place to help maintain balance.
Rather than trying to overstimulate the brain, the goal is to support:
Consistent circulation
Healthy vascular function
Ongoing cellular repair
This is where cGP comes in.
cGP is a naturally occurring molecule derived from IGF-1 in the body, and its role is to help regulate how IGF-1 is used.
Rather than forcing IGF-1 levels higher, cGP helps the body use IGF-1 more effectively. By supporting healthy IGF-1 regulation, cGP contributes to:
More consistent blood flow to the brain
Improved flexibility and health of blood vessels
Better overall support for the systems involved in memory and cognition
What These Moments Really Mean
That moment when something is “right on the tip of your tongue” is more than just forgetfulness.
It reflects how efficiently your brain is being supported behind the scenes.
Instead of thinking “something is wrong,” it can be helpful to see these moments as a signal that your brain may need a little more support.
By looking after circulation, vascular health, and the systems that regulate IGF-1 - including cGP - you give your brain a better chance to stay clear, responsive, and confident over time.
