This implies it helps reverse previous solar harm and reduces the chance of pores and skin most cancers, particularly basal cell carcinoma and squamous cell carcinoma. As Cureus journal factors out:6
“By offering a precursor molecule for a key element within the manufacturing of adenosine triphosphate (ATP), nicotinamide can even replenish mobile vitality after UV harm, thereby enhancing DNA restore.

The researchers famous, “Our outcomes ought to encourage suppliers to coach sufferers and their households about nicotinamide and its hyperlink to pores and skin most cancers prevention.”9
An excessive amount of nicotinamide will be counterproductive
Remember that the doses of niacinamide utilized in research range broadly and could also be on the excessive aspect. Usually talking, I solely advocate taking small doses of fifty mg of niacin thrice a day.
This dose has been proven to optimize vitality metabolism and enhance NAD+ ranges, that are the inspiration for optimum well being. If spaced, it may be taken 4 instances a day. Take one dose instantly after waking up and earlier than going to mattress, with two doses evenly spaced between these instances.
