Niacinamide — The Best Supplement to Prevent Skin Cancer

Within the video above, board-certified dermatologist Dr. Andrea Suarez, recognized on-line as Dr. Dray, shares some fascinating insights about niacinamide, a water-soluble type of vitamin B3 (niacin), and its advantages for pores and skin well being.¹

Niacinamide, also called nicotinamide, is a precursor for NAD+, which isn’t solely concerned within the conversion of meals to vitality however can be vital within the technique of repairing broken DNA. That is essential as a result of your pores and skin faces fixed environmental stressors, together with ultraviolet (UV) radiation, which might injury DNA in pores and skin cells and suppress your immune system.

Niacinamide exhibits promise for pores and skin most cancers prevention because of its capacity to reinforce DNA restore and cut back UV-induced immunosuppression in pores and skin cells. These mechanisms are helpful in stopping the event of non-melanoma pores and skin cancers (NMSCs), which embody basal cell carcinoma (BCC) and squamous cell carcinoma (SCC).

The Promise of Niacinamide for Pores and skin Most cancers Prevention

Scientific trials present that taking 500 milligrams (mg) of niacinamide twice each day considerably cut back the incidence of NMSCs in high-risk people.² This information was significantly encouraging for these with a historical past of pores and skin most cancers. Nevertheless, whereas many research for pores and skin most cancers prevention use 500-mg doses, warning is warranted.

Niacinamide at a dose of fifty mg thrice per day is a greater dose and can present the gasoline for the speed limiting enzyme for NAD+, NAMPT. I like to recommend getting niacinamide in powder type as a result of the bottom obtainable dose in most dietary supplements is 500 mg, and that can lower NAD+ because of unfavorable suggestions on NAMPT, which is the alternative of what you’re in search of.

Different analysis has proven a useful position of niacinamide consumption particularly for SCC danger discount. In a single large-scale examine involving the Nurses’ Well being Research and the Well being Professionals Observe-up Research, researchers discovered that whole niacin consumption was inversely related to SCC danger. The pooled hazard ratio was 0.84, suggesting a 16% decrease danger of SCC for these with increased niacin consumption.³

Niacinamide: Your Pores and skin’s New Finest Buddy

A examine performed in Australia and printed in The New England Journal of Drugs additionally discovered that this straightforward complement considerably reduces the danger of growing nonmelanoma pores and skin cancers.⁴ The examine, involving 386 high-risk sufferers, revealed that taking 500 mg of niacinamide twice each day for 12 months led to a 23% decrease charge of latest nonmelanoma pores and skin cancers in comparison with these taking a placebo.

This impact was seen in each basal cell carcinomas and squamous cell carcinomas, the 2 most typical varieties of pores and skin most cancers. Once more, the advantages of niacinamide have been most pronounced in sufferers who had a historical past of quite a few pores and skin cancers, suggesting it may be significantly useful for these at increased danger. The very best half? Niacinamide is cheap, simply accessible as an over-the-counter complement and comes with minimal, if any, unwanted side effects.

Along with lowering pores and skin most cancers danger, niacinamide confirmed spectacular ends in reducing actinic keratoses — precancerous pores and skin lesions that may turn into squamous cell carcinomas. Members taking niacinamide had 11% fewer actinic keratoses at three months and 20% fewer at 9 months in comparison with the placebo group. This translated to 3 to 5 fewer actinic keratoses on common.

The mechanism behind niacinamide’s protecting results lies in its capacity to stop adenosine triphosphate (ATP) depletion and enhance mobile vitality, enhancing DNA restore. Your cells want ATP for all times, restore and regeneration. Niacinamide additionally reduces UV-induced immunosuppression with out altering your baseline immunity, offering a two-pronged strategy to pores and skin safety.

Many standard chemopreventive brokers, reminiscent of oral retinoids, trigger vital unwanted side effects like dry pores and skin, elevated lipid ranges and even liver toxicity. Nevertheless, niacinamide confirmed no clinically vital adversarial results within the examine. Whereas the examine used a dose of 500 mg twice each day, the minimal efficient dose for pores and skin most cancers prevention is unknown.

Niacinamide Reduces Pores and skin Most cancers in Excessive-Threat People

For those who’ve had a number of pores and skin cancers previously, niacinamide is especially useful for you. A scientific assessment and meta-analysis revealed that niacinamide’s effectiveness in stopping pores and skin cancers tends to extend for people with a better variety of earlier pores and skin cancers.⁵

Niacinamide was efficient in lowering each BCCs and SCCs, with a 54% discount in BCCs and a 52% discount in SCCs in comparison with management teams. To reap the total advantages of niacinamide for pores and skin most cancers prevention, consistency is essential.

Once more, the research exhibiting vital reductions in pores and skin cancers used a dosage of 500 mg twice each day, taken orally for at the very least 12 months. This routine seems to be efficient for each wholesome people and organ transplant recipients, who’re at increased danger for pores and skin cancers because of immunosuppression.

Niacinamide: A Secret Weapon for Pores and skin Most cancers Prevention

In contrast to sunscreen, which blocks UV rays, niacinamide works by repairing DNA injury that has already occurred in your pores and skin cells. This implies it helps reverse previous solar injury and cut back your danger of growing pores and skin most cancers, significantly BCC and SCC. As famous within the journal Cureus:⁶

“By offering the precursor molecules for key parts to supply adenosine triphosphate (ATP), nicotinamide additionally enhances DNA restore by replenishing mobile vitality after UV injury. Present analysis additionally means that nicotinamide performs a job in blocking inflammatory cell activation and influences cell life span, survival, and most cancers development.”

The researchers famous, “Our outcomes ought to encourage suppliers to coach sufferers and their households on nicotinamide and its hyperlink to pores and skin most cancers prevention.”⁹

Too A lot Niacinamide Can Backfire

Remember that the niacinamide dosages utilized in analysis research fluctuate broadly and will be on the excessive aspect. As a normal rule, I solely advocate taking small doses of fifty mg of niacinamide thrice a day.

This dosage has been proven to optimize vitality metabolism and enhance NAD+ ranges, that are foundational for optimum well being. It may be taken 4 occasions a day when you area them out. Take a dose as quickly as you stand up, earlier than going to mattress, and twice evenly spaced between these occasions.

The issue with taking an excessive amount of vitamin B3, whether or not within the type of niacin or niacinamide, is that it’d backfire and contribute to heart problems^10,11 and different unwanted side effects. Dray stresses the significance of correct dosage and warned about potential risks of extreme consumption:¹²

• Ameliorate injury brought on by linoleic acid (LA) consumption

The final one is especially vital, as some of the poisonous metabolic byproducts of LA is 4 HNE, a poisonous aldehyde that seems to play a causative position in coronary heart failure.¹⁹ Thankfully, there’s an enzyme system referred to as aldehyde dehydrogenases that deactivates 4 HNE.

The easiest way to extend the exercise of this enzyme system is to ensure you have ample NAD+, and essentially the most environment friendly option to optimize your NAD+ degree is to ensure you’re getting 50 mg of niacinamide thrice a day.
