Effective in combo with L-tyrosine

Posted by Reviewer3281955 on Nov 02, 2012

Using Julia Ross's The Mood Cure, I decided to try this together with a 500-mg tablet of L-tyrosine to (1) lift my mood, which tends to be depressive and (2) lift my energy, which is similarly low. I take it once a day with a vit C tablet and a B-complex capsule, within 5 minutes of waking up in the morning. The effect is amazing: energises both my mind and body. For me it's better than any anti-depressant or cups of black coffee, and no side effects. I wouldn't be caught without it! Note: you can take it more often but preferably not after early afternoon because the energising effect is likely to give you insomnia. Once a day seems the perfect amount for me because ironically, when I tried it twice a day, it actually made me feel tired. So more is not necessarily better, although every person needs to find the right dose for themselves. Also, some people who find DL-Phenylalanine gives them headaches/insomnia/anxiety might like to try D-phenylalanine instead.

Life Extension, DL-Phenylalanine, 500 mg, 100 Capsules

Posted by noneofyourfrigginbusiness on Sep 30, 2012

Sometimes you take DL-phenylalanine and something happens; you get more energized. And a lot of times nothing at all happens. Part of that is because other nutrients such as vitamin B6 and vitamin C, folic acid and copper are needed in order to convert phenylalanine into noradrenaline and dopamine. These are essential nutrients that are required as co-factors to enzymes that are involved in the process of conversion. These materials - the copper and the vitamin B6 - are also required to convert phenylalanine into beta phenylethylamine, which is a neuromodulator in your brain that modulates the effects of noradrenaline and dopamine and probably some other neurotransmitters as well.

I can't feel any effect when using a serving size of two capsules, double the recommended amount.
