June 6, 2025: Not all fish oil is the same

Welcome to the first edition of Boost Brain Health. Each week, I’ll be sharing two habits, a lesson, and an inspirational quote to ponder on your longevity journey.

Two Brain Health Habits

Stay hydrated. Our brains are about 80% water and even a 2% drop in body mass, including fluid loss, can lead to brain fog and problems with coordination.

So, drink up. For women, that’s 8 to 11 cups of water a day. For men, it’s 10 to 15 cups of water.

Check the label for DHA. If you’re taking fish oil each day to stay mentally sharp, it’s a good idea to read the label. Not all fish oil is the same.

DHA (that’s docosahexaenoic acid) is considered the most important type of omega-3 fatty acid for building and repairing brain cells.

There is no official guidance on how much DHA a day to take, but 200 to 500mg of DHA a day, plus EPA (the other type of fat in fish oil), is considered good for overall health.

One Lesson

Our genes hold clues about our risk for Alzheimer’s disease. One gene in particular called ApoE, short for apolipoprotein E, is useful to know.

If you have a harmful variant of this gene, it clogs cholesterol transport in your brain and increases your risk for Alzheimer’s. That’s the bad news.

The good news is that this gene responds really well to lifestyle changes, like taking stronger doses of fish oil, regular exercise and detox.

If you’re in the US, you can find out your risk for Alzheimer’s, and what to do about it, through my new Boost Brain Health program.
