We do not. At 3 servings, of BrainHealth (BH), which is what someone about >65years old takes, you end up with 1.5gms. Keep in mind this is an aging “replacement dose” for supporting brain health as we age. Very high doses, (far more than 2gms/d) are often used (experimentally) in brain injuries. But this has only been studied acutely at very high doses and primarily in animals, however there are encouraging human results for use in brain injury.
