Popular anti-aging vitamin B3 pills ‘increase cancer risk’, study suggests.

  • Nicotinamide riboside, a source of vitamin B3, is known for its anti-aging effects
  • But studies show that it increases the chance of cancer spreading to the brain
  • This is a fatal development for many patients, because there is no viable treatment

A popular dietary supplement may increase the risk of cancer, studies have shown.

Nicotinamide riboside (NR), a form of vitamin B3, has been advertised as having anti-aging effects, as well as lowering high cholesterol and blood pressure.

But in a study conducted on mice at the University of Missouri-Columbia, NR increased the risk of breast cancer and caused the disease to spread to the brain, which is fatal.

NR pills cost around $0.60 per tablet and can be purchased at Amazon and most health stores.

The supplement is converted by the body into nicotinamide adenine dinucleotide (NAD+), a coenzyme that is key to providing energy to cells. Cancer cells feed on this energy, so the researchers wanted to look at the role of NR in the spread of cancer.

“Some people take [vitamins and supplements] Because vitamins and supplements are assumed to have only positive health benefits, but very little is known about how they actually work.’

The supplement industry is booming in the US, with more than half the population taking it regularly and spending $1.5 billion a year.

Britons spend £430 million a year on vitamin or mineral pills, with an estimated 20 million taking some type of supplement every day.

Several studies in recent months have shown that many popular supplements, despite the big claims on their packaging, do not bring about healthy changes.

Supplements commonly used for their anti-aging properties may increase the risk of breast and brain cancer, University of Missouri-Columbia researchers have found (stock).

What is ‘NR’?

Nicotinamide riboside or niacin is an alternative form of vitamin B3.

It is touted as an anti-aging supplement because it increases your body’s levels of NAD, which is used as fuel for many key biological processes.

It also helps in liver and brain function, helps in weight loss and promotes muscle aging.

However, there is no solid scientific evidence to support these claims.

NR is found in fruits, vegetables, meat, milk, yeast and beer.

It comes in capsule or tablet form and can be found online or in health food stores.

It is sometimes combined with other ingredients such as antioxidants.

Most brands recommend taking 250-300mg per dose, which is around 1-2 capsules.

The researchers used bioluminescence – the light emitted by living things through chemical reactions in their bodies – to develop a technique to measure NR uptake in mice.

The presence of NR is indicated by light, and the brighter the light, the more NR there is.

Mice with cancer were injected with nicotinamide riboside and then photographed using a special light-sensing camera.

The researchers monitored their cancer cells, T cells (a type of white blood cell) and healthy tissue.

NR increased the spread of cancer cells to the brain in nine of the 11 mice, compared to only three of the 12 mice in the control group who were not given the supplement.

The researchers found a three-fold increase in light and NAD + levels in activated T cells.

This combination suggests that T cells transport RNA into cells, giving them more energy to feed on cancer cells.

They also applied the technique to breast cancer cells, and found that high levels of NR could increase the risk of triple-negative breast cancer (TNBC).

The researchers said: ‘Our data show that NR supplementation causes a significant increase in cancer proliferation in a TNBC mouse model.

‘Furthermore, we observed a significant increase in the rate of brain metastases, indicating an important role for NR in cancer development.’

Brain metastasis occurs when cancer cells spread from their original location to the brain. Once the cancer reaches the brain, the outcome is fatal because there are currently no viable treatment options, Dr. Gown said.

She added: “Our work is particularly important in terms of widespread commercial availability and numerous human clinical trials where NR is being used to reduce the side effects of cancer treatment in patients.”

She said further testing is needed because of potential side effects.

Three months after her father died of colon cancer at the age of 59, she was inspired to learn how cancer spreads through the body.
