Source NaturalsNADH, Coenzyme B-3, for Energy and Mental Alertness*, 5 mg - 30 Enteric Coated Tablets

Purchased on recommendation from my doctor. They do seem to give me a little more energy other then that not sure how well the a working.

Small pill easy to swallow, I have fibromyalgia and possibly chronic fatigue, other people with these conditions mention this for energy so I decided to give it a try and it works wonderfully, no side effects that I can tell yet, I've been taking just the 5 mg a day, works wonders

Best thing I have used to combat fatigue. I work long hours and on my workdays they have enabled me to work more efficiently. Additionally I would like to say anything I have used that was Source Natural Brand has been of exceptional quality.

It was a game changer in treatment of ME/CfS. Great product.

The dosage in the 5mg product seems a little low. This is a temperature sensitive product. If it gets above 75 degrees, it could lose potency. Get it in the fridge as soon as you get it. Also, make sure you have a well balanced diet with nutritional supplements as needed. NADH needs lots of nutrients to do what it does. Good Stuff.

Can't go wrong with Source Naturals. I've taken these for years. Tried others and just don't have the same effect.

It seems to work well. I seem more clear headed sense I have been using it. Is there a cdc recall?

Maybe just my metabolism but I found myself with far less energy and feeling lethargic.For me this product did not work well.I generally get up a t 5am, workout, have breakfast and head out to work.After taking this supplement I had trouble getting up in the morning, struggled through my workouts in the AM, if I did them at all, and was practically comatose by lunch.I have since stopped taking the supplement and seem to be getting back to my normal routine. My work out energy is low but appears to be coming back.
