Can you tell me if I could take reishi, ashwagandha, bacopa, phosphatidylserine together?

Why???? (sigh) Why are people so willing to do things to their bodies they'd NEVER do to their cars? If a fuel additive sold at Pep Boys had as little evidence of efficacy as these herbals, you'd NEVER trust it in your gas tank. Think critically. Be skeptical. Look at FACTS. Acquire some real knowledge. Don't get taken in by every traveling medicine show or snake-oil salesman that comes down the pike.
