Boosting Cerebral Blood Flow:

3 Generations of options

If you have a child with special cognitive needs you know that optimizing cerebral blood flow – to get vital oxygen and nutrients deeper into the brain – is a holy grail goal.

Over the years, the methods available to support blood circulation, reduce neuroinflammation, and encourage tissue repair have completely transformed.

🧠 Our family has transitioned away from both the ancient (Gen1) and clinical (Gen 2) methods to a modern, $40 game-changer and we’ll tell you why.

Generation 1

The Herbal Approach (Vinpocetine)

Long before modern technology, targeting brain blood flow meant turning to nature.

Vinpocetine is a compound derived from the periwinkle plant.

We’ve used many herbal remedies in the past, but because plants are broad spectrum and foreign to our body, they can also bring some unintended effects.

In our experience, only select superstars (such as saw palmetto, goldenseal, St. John’s wort) work as well as we hope they will!

The Science

Vinpocetine functions primarily as a vasodilator, relaxing the smooth muscle walls of blood vessels.

This widening allows blood to flow more freely to the brain.

It also inhibits an enzyme called PDE1, which helps support brain metabolism and cellular energy.

Our Experience: While the science makes sense on paper and it’s very affordable, this remedy did not give us great success.
- It also triggered headaches, a known side effect.
- Andy Cutler was a big proponent of Vinpocetene over HBOT because of concerns the pressurization could drive heavy metals further into tissues.

Generation 2

The Medical Tech Era (Hyperbaric Oxygen Therapy – HBOT)

As medical technology advanced, HBOT replaced supplements as the gold standard for improving cerebral blood flow via deep cellular oxygenation.

The Science

HBOT works by placing the body in a high-pressure chamber filled with highly concentrated oxygen.

The intense pressure forces oxygen directly into the body’s plasma and tissues, bypassing regular red blood cells.

The oxygen flood acts as a signaling mechanism that triggers angiogenesis, the physical growth of new capillary networks.

Our Experience: We did about 80 hours of HBOT in the past, and it undeniably helped! (See below photo)
- The time commitment and massive financial investment make it impractical for long-term, everyday maintenance.
- It often flares yeast as a side effect and can cause other unwanted issues. Some gains lasted, most faded with time.

Generation 3

The Molecular Era (Thymosin Beta 4 amino acids)

Ironically, the cutting edge of science is bringing us right back to nature.

But it’s not plant nature this time, it’s our own nature.

While HBOT relies on outside forces of machinery, a more modern approach taps directly into our native biology.

Thymosin Beta 4 is a repair protein found naturally in the body and Fragment 17-23 is a chain of 7 amino acids that make up a portion of it.

The Science

This short amino acid chain acts as a targeted cellular messenger.

It specifically signals cells to initiate tissue repair, cell migration, and the growth of new capillary networks.

Essentially, it hits the exact same healing and blood-vessel-building pathways as HBOT, but through direct molecular signaling.

Our Experience: We’ve seen improvements incredibly similar to but at an even greater magnitude than what we saw with HBOT.
- It has brought a profound sense of calm to our household (including my ADHD), clearer and more sophisticated language & motor planning, greater idea generation & initiative, social desire, elimination of screen time, and dramatically deeper cognitive focus. (See below)
- We use it as a sublingual spray (under the tongue) in the morning, about 3-4 times a week. The cost was about $40 (lasts a few months)
- We haven’t observed any side effects. I assume some gains are lasting and some will fade with time, but repeated use is easier than keeping a giant HBOT in our home!
