Calming and stimulating at the same time, also helps my cold extremities. I am slightly low DHEA, and found this 50mg to be a bit too much for me and sometimes gives me headaches, which I finally managed by taking only half a capsule.

This product is great for providing me a mild effective boost in energy, focus and enjoyment, something that I failed to experience with tyrosine. Long term use however is not advised, I always experienced depression afterwards and later found out that L-DOPA was demonstrated to also deplete serotonin so I make sure to administer 5HTP concomitantly. EGCG may too be considered for preventing the breakdown of L-DOPA before reaching the brain

I bought this product for CFS and for the fact that studies show it's dopaminergic traits, and found it gave me overall energy about 1-2 hours after taking it. It's not the kind of energy that extinguishes the sensation of lack of sleep, neither does it feel like a stimulant with vasoconstriction and other side effects, but I sense good pure pshysical energy and stamina with it, and rather unchanneled mental energy, the latter which makes it less impressive in the cognitive department even though my mind feels awakened by NADH.

... I am a bit afraid of any long term side effects this may have as I couldn't find enough information on this topic. I am 30 years old and just one day after taking this product I felt rejuvenated. Mental clarity and memory for which are purchased it are indeed enhanced

For me one dose of this product provided mental clarity and endurance through the day, as well as slight general health improvement such as resistance to cold.

Though pretty subtle for me in effect this lifts my mood and gives me a sense of hightened awareness, allowing me to go through the day with sufficient energy like no other product. It is relaxing my mind and though people may take 5HTP before sleep I find this one rather energising, perhaps too in light of the body feeling due to peripheral 5HTP conversion which is not disturbing enough for me to note, but I used a different enteric coated 5HTP which lacked this feature though overall was not as effective as this time release version.

I enjoyed using many quality B-complex products and this one provides the same mental and physical push along a subtle calming sensation. It seems also well balanced for me, no stomach distress as I experienced with others. It's oddly cheap and effective.

Doctor's Best is an OK brand in my opinion, and Ginkgo may work on some people, but I took this daily for a couple of weeks and observed no improvement in cognition, attention or memory. I expected this to help with my cold extremities as well and I felt no benefit in that respect. If anything, I felt a bit dizzy and slightly nauseous at the beginning when taking it, which made me wonder how come some people take it for vertigo.

It feels very healthy after one cap, also the clarity of the mind on this supplement is great
