Vitamin supplements are becoming an important way for modern people to efficiently achieve health. Vitamin E, vitamin B, and so on, seem to give people a boost of energy with just one daily pill.

However, the reality is not so simple. These extra large amounts of vitamins may do more harm than good to health, stimulating tumor growth and accelerating cancer metastasis. Multiple studies have provided solid evidence!


 
Gas station for cancer cells?
Beauty's VE    

Vitamin E is an antioxidant commonly consumed by many women for beauty and anti-aging purposes. However, in recent years, an increasing number of studies have found that the relationship between vitamin E and cancer has become increasingly ambiguous.

Research published in the top-tier journal "Nature" has conclusively shown[1] that vitamin E can help cancer cells survive the ordeal, resisting ferroptosis.

It should be explained here that during rapid development, tumors undergo oxidative stress in cancer cells, driving lipid peroxidation and inducing ferroptosis of cancer cells. In other words, for cancer cells to continue to grow and expand, they must find ways to resist ferroptosis.

Vitamin E provides α-tocopherol, which can help cancer cells neutralize the toxicity of lipid peroxidation, thereby enabling cancer cells to escape the calamity of ferroptosis and promoting tumor growth and development.

In addition, two studies published earlier in the top academic journal "Cell" also found [2-3] that in tumor-bearing mice administered with anti-vitamin E, the incidence of lymph node metastasis was 6-7 times higher than that in the control group of mice! Furthermore, vitamin E can also promote distant metastasis of lung adenocarcinoma .

Overall, vitamin E antioxidants make cancer cells stronger!


Opening a backdoor for cancer
Improper VB supplementation
   

B vitamins constitute a large family, including the well-known B3, B5, B6, B12, and so on.

A study published in Nature Metabolism in 2023 pointed out that[4]:Breast cancer cells with high expression of Myc are heavily dependent on vitamin B5 for growth and survival.

A study published by a research team from the Swiss Federal Institute of Technology has also attracted attention[5]: a form of vitaminB3 - nicotinamide riboside (NR) (NR), this substance often appears in ""anti-aging"" nutritional supplements, but research suggests that improper supplementation or excessive dosage may increase the risk of serious diseases, including the occurrence and metastasis of cancer.

Researchers speculate that excessive supplementation of nicotinamide riboside (NR) may enhance the "metastatic potential" of cancer cells, on the one hand providing stronger metabolic support for tumors, and on the other hand potentially weakening the integrity of the blood-brain barrier, making cancer cells more likely to "break through defenses", invading the central nervous system.

Vitamin Supplements    

The human body's nutritional needs may change with age and physical condition, and the need for vitamin supplements may vary."Depending on the individual and time".

1、 Accurate supplementation

Before starting vitamin supplementation, serum vitamin levels can be testedCheck to see if there is a true deficiency. Cancer patients need to pay special attention to these items: Serum cobalamin (vitamin B12); Serum 25(OH)D (the main storage form of vitamin D); Serum α- tocopherol (vitamin E) and other indicators.

2, dietary supplementation takes precedence over pharmaceutical supplementation

 Supplementation with vitamin Bfamily

② Supplementation with vitamin E

blindly may not be a case of "adding flowers to a brocade " , but rather "pouring oil on fire " , and may even "fuel the flames " for cancer risk.

Put down your phone, take a look at the vitamins in your home now, and forward this article to your friends who take "nutritional supplements" as breakfast every day. By forwarding it once, you might just wake up someone who thinks "vitamins are like sugar beans".

In summary, please check before eating.
