Dosage Uncertain; Cost is Excessive
When you compare the Clinical Trial (as published by HHS & FDA) it seems as if the dosage was deliberately reduced from the Trial dosage. It seems that users will require approximately 500 mg to experience Trial results and that means two (2) bottles @ $46.00 are required to experience results similar to those shown in the Trial? I work in Biotechnology and hold several US Patents in the Medical arena, so I have a better understanding than most; I also used to teach the Martial Arts in Wash, DC so I also am familiar with 'extreme' training regimens. NIAGEN can be considered pricey. jacVerified purchase: YesCondition: New

Not sure how long it takes for this to be effective but so far I have felt absolutely nothing from this product. Really feel I threw my money away on

Unconvinced
I can't criticize the product, but I don't see much effect after a month of using it. Don't really know what to say. Nice package, nice service. Maybe it takes longer to have a effect.Verified purchase: YesCondition: New

right dosage, generous amount in bottle, affordable.
The dosage and the quantity reflected the criterion I have been looking for. I am 55 years old and since taking this product consistently over the past 4 weeks, I have not felt as energetic nor spritely since my 30's. I will definitely be purchaser this product again.Verified purchase: YesCondition: New

Love it.
I am a nurse who assists in orthopedic surgery and could tell immediately a difference in my ability to stand 12+ hours without the pain and leg cramps. My stamina is better and overall I just feel better. I will be reordering.Verified purchase: YesCondition: New

Will take some time to assess validity
Its a little early to provide a testimonial but I was surprised not to receive any product details contained within the packaging nor invoice or advice note from the USA supplier. I will report back again if I can see any benefit from this supplement.Verified purchase: YesCondition: New
