 These are three tropics that are probably not supplementing yet but you should consider supplementing them. The first one is urethane monophosphate. Now urethane monophosphate is a building block of DNA and RNA that can cross the blood-brain barrier. Studies show that it can improve your mental performance and it's very effective in doing that and that's why I highly recommend taking them. The second tropic is called Celastrospanicolatus that has been used in Ayurveda for centuries. Now it can improve your memory, it can help with stress and it can also offer neuro-protection and that's why you should consider taking it as well. And last but not least there is Phosphatial Dysurin. Phosphatial Dysurin is a naturally occurring phospholipid in your brain that naturally decreases with aging and that's why many people supplement it. Now supplementing Phosphatial Dysurin can improve your focus, your attention and it can help you with stress. If you take those three tropics and combine them with coli and some omega-3 you should definitely see and improve brain performance.
