Check with your physcian before taking this supplement. I've experienced good results.
Source Naturals DLPA DL-Phenylalanine, 750 mg - 60 capsules: Always be responsible and consult with your physician before taking OTC supplements! These can have serious side effects depending on other medications or health conditions. I recommend reading the book, "The Mood Cure" by Julia Ross; it is a guide to help your determine if this product may be helpful, how and when to take it throughout the day, in combination with other supportive supplements: L-Tyrosine, 5-HTP, GABA (read the book, you may not need all four), in addition to other vitamins and minerals that assist these supplements to provide optimum benefits. The condensed description is that DLPA helps to desensitize from 'life's pain'. I have used this successfully and experienced good results. Again, I cannot stress this enough, proceed with caution with the support and advice of your physician.

Unstoppable Focus & Calm Energy
Love this product!! Just heard about DLPA from a YouTuber as an amino acid that helps with concentration. Thought I knew of all the other things that are supposed to do similar thing (gingko, ginseng, etc.) but there's no comparison. This nutrient awakens something in your brain without you even realizing it. Then you look back at end of the day amazed at all you've accomplished. First day I suddenly had the mental energy to start deep cleaning my kitchen, organized clothes & drawers in my bedroom, decluttered my email Inbox, etc. And you don't feel the anxious jitters from coffee or other caffeine. You just get wings to be productive. I only take 2-3 times per week though and that works for me. Always going to keep in my cabinet as part of my health routine.

DLPA for Fibromyalgia Pain and Mild Depression, It works!
DLPA is a combination of 2 forms of the amino acid phenylalanine. It is known for its antidepressant properties, especially when combined with other supplements (I also use SAMe and 5-HTP). It's reported to increase your levels of norepinephrine, which is an important player in both depression and attention issues. I have fibromyalgia and I use this daily for the treatment of mild depression & chronic pain issues. I do notice a difference while on it. I went off of it briefly and felt as if someone had let the air out of my balloon, just kind of deflated. I believe many of us with chronic pain suffer with depression, and its a cyclic thing: more pain = more depression... and the more you are depressed, the worse the pain feels. It really effects your quality of life! I take one each morning on an empty stomach and have just added another at night in hopes that it will help with my insomnia. Being perimenopausal has wreaked havoc on my sleep schedule! I do not experience any drowsiness with the morning dose, but I suppose more sensitive people might. I'd suggest trying it out yourself to be sure, or just take your dose at night. It seems to be one of those supplements that give some people energy and others it makes sleepy. Source Naturals price per pill makes this one a good value for the price. These pills are a bit smaller than other brands I've used and I've had no problems swallowing them.

I’m a pharmacist and this is my favorite brand and dosage for this supplement
I can’t say whether I notice a huge difference when I take this or when I skip it (the case with the majority of supplements because they can give someone a placebo effect making them think since they are taking it, it’s made a huge change for them, however, there have been a few times when I truly do think it has helped a little bit and helped my energy and focus a tiny bit as well and for something as easy on your system as this which mimics a natural amino acid in your body, I do feel It is worth it and will continue to take it unless the price keeps rising to be ridiculous, which I have noticed the price has increased since I first started buying this brand. I’ve purchased a couple other brands to try to save money but I just never have gotten some of the better feelings I have with this brand and dosage. Just please don’t increase the price anymore or else I will go to another brand.

Contains other ingredients
Be careful because this one contains dibasic calcium phosphate, stearic acid, sorbitol, magnesium stearate, silica and modified cellulose gum. Something in this made me break out in a rash. The pills themselves are large and chalky - not capsules. I switched to L-Tyrosine and am glad I did. I did not experience any extra energy with these. In fact, my protocal called for me to take two at 8 am and, on days when I did not have to work, I could go right back to sleep. L-Tyrosine works better for me.

It helps
It helped me getting off pain killers after finally getting surgery on leg and hip. Also it makes you happy and more focused. Probably due to increased dopamine
