Whole Food B Vitamins vs. Niacinamide as Protection Against Skin Cancer

Are coal tar-derived and hexane-based B vitamins, such as niacinamide, truly a key answer for the propensity to develop skin cancer? This is what recent media reports would have people believe? Is the evidence strong enough to recommend such chemically-created vitamins as a preventive and also a treatment?
It is all in respect to the known fact that ultraviolet light can be damaging to the human immune system, while also causing damage or breakdown of the skin’s DNA. Apparently, niacinamide blocks this destructive action.
In this regard it is said that niacinamide or vitamin B-3 protects against “immune system suppression” caused by ultraviolet ray exposure. If the immune system corruption is left unaddressed, skin cancer can develop.
The immune system response, it has been determined, can be negatively affected by exposure to relatively tiny amounts of ultraviolet light, as little as five to six minutes’  exposure on a sunny summer day.
No one is saying that the B vitamin prevents damage to skin cells by UV radiation. What is stated, though, is niacinamide “repairs damage to DNA, while helping to heal broken DNA strands.”
Niacinamide is a crucial precursor to the formation of the co-factor NADH, a coenzyme found in all living cells. It is NADH which is necessary to energy production in cells, while also assisting in the repairing of damaged DNA.
The claims are based on studies such as this, published in Carcinogenesis:

To interpret this it means that there was some positive effect that was statistically significant. This positive effect occurred in people with heavily damaged skin. The synthetic B vitamin acted on pre-cancerous lesions, known as actinic keratoses, reducing their incidence. Notice what is said about skin cancers, which is that niacinamide “may reduce” the incidence of such cancers, that is specifically those of the non-melaonma type.
It “may” work is the best that is said. Therefore, the results were not exceptionally definitive. The conclusion of the authors in the study is as follows:

It has “potential.” Yet, does it really work to block and prevent skin cancer development? Somehow, the authors believe this to be the case, once again based on the action of the vitamin regarding the pre-malignant lesions:

Yet, the positive effect was not exceedingly compelling, as demonstrated by the following screen capture:
 

It was a “23 percent” reduction: not that overwhelming. Moreover, the category of people with the presumed benefit was only those who had a history of at least two other skin cancers in the past.
Natural source B vitamin supplements: a more potent answer for skin cancer prevention
Are natural-source B vitamins more powerful than the chemically derived ones in the prevention of the skin cancer epidemic? Natural sources of niacinamide and other key skin-supporting B vitamins, such as pyridoxine and folic acid, include rice bran, torula yeast, brewer’s yeast, and royal jelly. Let us see what the research demonstrates in this regard.
These are powerful food complexes containing far more than mere B complex vitamins. Studies have shown that, for instance, yeast extracts, royal jelly, and rice bran actually fight and reverse cancerous changes in the skin. These whole food sources also help prevent the skin from degenerating from aging as well as excessive sun exposure.
Rice bran and its extracts is are prominent examples. They offer great protective effects against cancerous degeneration, not just in the skin but, rather, in virtually every tissue of the body:

Is it not astounding? The rice bran phytochemicals, not merely the B vitamins, offer profound protective effects against a wide range of cancers, yet it is not merely this. These potent phytochemicals motivate, that is activate, the immune system’s “anticancer..responses” by a variety of mechanisms, including the regulation of enzymes which metabolize and purge carcinogenic substances. No synthetic vitamin can achieve this, not even remotely so.
Here is additional research on fermented rice bran, proving its powers in prevention as well as treatment:

Royal jelly is also a potent cancer-preventing and -fighting agent, whose powers supersede it’s mere vitamin content. In a study by the Journal of Cancer Prevention it was found that royal jelly had a powerful effect on preventing UV damage on irradiated mice. In all groups tested the “royal jelly decreased the degree of DNA damage…,” incredibly, “to the level of untreated, unirradiated mice.” The results demonstrated that the daily ingestion of this health food complex greatly “reduced DNA damage” to mice exposed to toxic levels of ultraviolet radiation.
One mechanism explaining this relates to the collagen-inducing powers of this miraculous substance. Royal jelly actually contains a considerable amount of this key skin-reviving protein, more so than any other food or super-food:

It is a tremendous feat that in de-estrogenized female rats that royal jelly could achieve this, which was, essentially, to cause an increase in the production within the skin layers of this skin-vitalizing protein. It is a healthy collagen layer which protects against the development of skin cancer. Moreover, collagen is precisely the protein which is destroyed by the excessive exposure to ultraviolet rays.
Edible yeast concentrates, both brewer’s and torula, have also been demonstrated to have protective powers for skin health. Studies have demonstrated that such yeasts, as food supplements, can reduce the occurrence of cancerous cells in the tissues. Regular use of edible yeast supplements also reduce the appearance of liver spots and sun damage-related pigmentation marks on the skin. This makes sense, since edible yeast is a top source of cancer-blocking nutrients, including selenium, niacin, pyridoxine, folic acid, and riboflavin.
No doubt, these yeasts are powerful complexes for cancer protection. It is the full complex of nutrients as found in whole foods which offers real, definitive protection, not single, isolated, chemically-created nutrients. One of the key studies in this regard was conducted by the Nutritional Prevention of Cancer Study Group via the investigation, “Effects of Selenium Supplementation for Cancer Prevention in Patients with Carcinoma of the Skin.” In the study a mere tiny dose of yeast was used, though it was a high-selenium variety. The results in this human trial of some 1300 patients was profound. According to the investigators while there was no obvious effect on skin cancers there was a “52 per cent reduction in total cancer mortality, a 17 per cent reduction in all cause mortality, a 37 per cent reduction in total cancer incidence, a 46 per cent reduction in lung cancer incidence, a 58 per cent reduction in colon cancer incidence and a 63 per cent reduction in prostate cancer incidence.”
In an investigation by the NIH’s Dr. M. Ghoneum yeast extract was shown to have a definitive effect against skin cancer. Cancer cells from humans suffering from breast, oral, and skin cancers were harvested, then incubated in vitro with brewer’s yeast. The results were astounding. When the cancer cells attempted to ingest the yeast elements, they died, being completely obliterated.
Another phase of the experimentation involved injecting cancerous lab rats with yeast extract. After this procedure, a significant decrease in the cancer cells mass has occurred to the lab rats used for the experiment. Soon thereafter, the cancerous cells were completely eliminated through the yeast therapy.
This, then, demonstrates the value of a whole food B complex supplement for human use in the fight against degenerative diseases, including in the battle to prevent skin cancer and other skin degenerations. Ideally, such a powder should contain the supplemental B complex sources, rice bran, edible yeast (brewers or torula), and royal jelly.
So, use whole food supplements for the B complex source when attempting to boost the immune system, whether for the fight against skin cancer or any other. Through such complexes far greater benefits will be procured, surely far greater than the use of single, isolated nutrients.
