In previous posts, we looked at critical nutrients for optimal brain function. But the essential medicines are invisible, primarily free and usually overlooked.


Your brain is over 70% water, and it only takes a 1-2% dehydration drop to cause adverse effects. Some severe cases of dehydration can mimic the symptoms of dementia.

You could argue that water is the most critically lacking energy and health promotion substance in our modern lifestyle.

Most of us avoid water as a casual beverage because we prefer caffeinated or sweetened drinks. Unfortunately, these drinks only contribute to dehydration. Consuming diuretic beverages such as coffee, tea, energy drinks, etc., causes more significant water loss overall than we take in. For every 10 ounces of caffeinated beverages, we lose up to 12 ounces of water.

Even non-caffeinated herbal teas can cause this dehydration effect.

I recommend reassessing your water consumption. Everyone is different. Consider the climate you live in and how much exercise you do. A good rule of thumb is to divide your weight in pounds by two and aim for that many ounces of water.


Oxygen is one nutrient the brain can’t live without for more than a few minutes.

While you’re alive, you are getting enough oxygen to survive, but you may not get enough for your brain to thrive.

Modern-day living causes weak breathing muscles and poor sleep habits. Check out the thousands of videos online on how to breathe correctly and strengthen the primary and secondary muscles of breathing.

All the best,
