BrainStrong Adult is a nutritional supplement that consists of an algae-derived form of DHA (docosahexaenoic acid), an Omega-3 fatty acid found in fish.
I-Health claims their product to be highly effective in protecting the brain from cognitive decline, in boosting memory, in supporting clarity, and in improving the overall health. It is true that DHA is critical for adult brain function, and it has been showed that dietary consumption of DHA is typically low in Western countries, but the evidence is insufficient to determine whether taking DHA-based supplements can help with that problem or not. Furthermore, the American Academy of Pediatrics has no official position on Omega-3 fatty acids brain supplements for children, stating that large clinical studies are lacking.
Most people can obtain all the Omega-3 fatty acids they need from just two servings a week of fish, such as tilapia, wild salmon, and mackerel. Vegetarians can get their Omega-3 daily needs from walnuts, flaxseed, and canola oil. Keeping a balanced diet will render most DHA-based supplements useless.
