My brother in law wants to take turmenic curcumin with with bioperine 1500mg to improve a poor focus and concentration. he is wondering if this supplement will actually help him with that problem? thanks in advance?

Turmeric or other OTC preparations lack ability to improve focus and concentration. Several available agents, such as Focus Factor (R), make extravagant claims, none of which are proven, at this point. Biologically active B vitamins seem useful, such as high dose folate, to stabilize emotional and cognitive problems (Deplin), but these are prescription items. Other Rx preps may be considered.
