Bests & Worsts Reviews from Amazon

I want to say that I do believe supplements can affect people differently. However, this product did absolutely nothing for maintaining my baseline energy level. Within 4 months of taking this product I was physically and mentally struggling all day long from the time I woke up until I went to bed. I even got tested for Lyme Disease (which came back negative). I usually take the sub-lingual form of enada and had done so for the past 14 years. When I found this NOW NADH product I wanted to give it a try because it was twice the quantity for about the same price as the sub-lingual NADH I was taking. I have always ordered enough of my NADH to last through the summer months because none of these NADH supplements should be exposed to heat. In fact, I store mine in the fridge. So, I ordered these NOW brand NADH in a quantity of 4. They are capsules filled with tiny beads and I took them every morning as instructed for 4 months. I did begin to feel sluggish after a couple weeks and wondered if this NADH product was not performing well for me. As the weeks and months passed, I felt more and more exhausted upon waking and found it difficult to do my daily activities. I typically take 50 mg of caffeine in a green tea supplement with my NADH to give me the extra energy I need for my physically demanding work schedule. While using this NOW NADH I was forced to start taking 100 mg of the caffeine green tea supplement with only marginal increased energy that lasted a few hours. When I tested negative for Lyme I had to accept that these NOW NADH capsules were useless in helping me cope with my Chronic Fatigue Syndrome. I immediately ordered my sub-lingual NADH (no chlorophyll additives). It has only been about 2 weeks, but I feel so much better. My 50 mg of caffeine in my green tea supplements have also been enough to give me the extra zip I need for an entire day of energy. Without my sub-lingual NADH I fall below the baseline level for normal energy. For me, NADH gives me a normal level of energy. It never gave me the typical energy rush like caffeine, but without NADH I am not able to function "normally." NADH gives balance, STAMINA, and a sense of well being. I believe you should expect no more than that. It is subtle but very necessary for me personally. In the end, I believe that only the sub-lingual form of NADH works properly. PLEASE NOTE that it is vital to limit swallowing while the sub-lingual melts under the tongue. Saliva helps the NADH melt and become absorbed completely into the bloodstream. This should take no more than about 10 - 15 minutes. I have read where people say it takes 30 minutes to 1 hour for their sub-lingual to melt. I think they are swallowing their saliva too frequently and keeping moisture from melting the sub-lingual tablet.
