Colon cancer has become a growing concern, especially among young adults. While a healthy diet and an active lifestyle play an important role, a certain vitamin has come into the spotlight, as it is believed to not only prevent the chronic disease but also help manage it better in people who are diagnosed with it.

In his new post on Instagram, gastroenterologist Dr. Joseph Salhab reacted to a video in which a woman wrote, “Reminding my sister to take her vitamin D because colon cancer is on the rise for Gen Z.” This makes one wonder if optimal vitamin D levels can actually cut your risk of colon cancer. According to Dr. Salhab, it does make a difference.

Vitamin D and colon cancer

Sharing studies that support the claim, he said, “In general, if you are vitamin D deficient, as vitamin D levels go up, the risk of colon cancer goes down, even in early-onset colon cancer in younger people. This is also especially true for women because estrogen may help vitamin D’s effect.”

Healthy levels of vitamin D are not only helpful in preventing colon cancer risk but also useful for treating those who have been diagnosed with it. “It may even improve survival in people already diagnosed and being treated for colon cancer,” the gastroenterologist said.

While it may help people who are deficient in the vitamin, the same is not true for those who already have sufficient levels. Dr. Salhab said, “Now, for those already in optimal ranges, adding more supplements hasn’t consistently been shown to provide that benefit.”

He concluded that what matters is getting your vitamin D checked, especially if you’re female, and talking to doctors about ways to bring it into the optimal range if it’s low.

What research says

According to the ‘Vitamin D and Colorectal Cancer Prevention’ study, vitamin D plays an important role in lowering the risk of colorectal cancer affecting younger adults. Researchers found that a high dietary intake of vitamin D (80 ng/mL) resulted in a 25% decrease in colorectal cancer risk compared to those with the lowest amount (10 ng/mL).

This is also backed by data from the Nurses’ Health Study conducted in the US, which evaluated risk factors for chronic diseases in women and revealed that the highest levels of vitamin D reduced the risk of colon cancer by 58% compared to those with the lowest intake.

Vitamin D plays an important role in the body, including regulating energy levels and the health of the bones, brain, heart, and gut. Its deficiency, however, can negatively affect the intestinal barrier and cause inflammation, which can trigger cancer growth.
