Best supplement for focus?

Andrew Huberman AI:

There are several supplements that can enhance focus and cognitive abilities. Here are a few that I've discussed on the show:

  1. Caffeine: This is a stimulant that can increase levels of alertness and focus. The appropriate dosage is usually one to three milligrams per kilogram of body weight, taken about 30 minutes before a mental or physical endeavor. It's important to note that caffeine can still enhance focus even if consumed regularly, but its effects can be more potent if you take a break from it for a couple of days before an important event. However, avoid consuming caffeine too late in the day as it can interfere with sleep.

  2. Omega-3 Essential Fatty Acids: Specifically, one to three grams of EPA essential fatty acid per day can improve mood and cognitive function, which in turn supports focus and concentration. These can be obtained from supplements or food sources like fatty fish and algae.

Remember, the best cognitive enhancer is a good night's sleep and sufficient nutrition. Overeating or being overly hungry can also affect your ability to focus.
