Ok, so I've been in this "state" while in college. Oh how the sunday hangovers allowed me to be so productive. I Identify with this thread so much...Anyways, tetrahydrobiopterin is a major player in this. I just came here to say you need to try Liposomal Vitamin C + your flavanoid of choice. The Liposomal vitamin c stimulates BH4 creation somehow through hydrogen peroxide (isn't hydrogen peroxide bad). The flavanoid is necessary to ''couple" the endothelial system and promote enos. Without enough BH4 you don't produce enough enos, and create inos and peroxynitrite instead.
ANYways you guys need to definitely try liposomal vitamin c with your flavanoid of choice. Let me know what you think.Cheers
I've personally stopped using the BH4 supplement I was using before due to costs and storage difficulties. Nowadays I use a combo of hydroxy-B12 (250 mcg once a day), methylfolate (200 mpg 3 times a day) and vitamin C (1000 mg 2 times a day) instead. The vitamin C seems to make a big different in the way that I have more energy, motivation and it's easier for me to socialise on the days I take it. I use regular vitamin C though, not the liposomal version and without any flavonoid.
