Now, a new study, published in the scientific journal Aging Research Reviews , suggests vitamin D3 may even help reduce the likelihood of dying from cancer, according to Express .
According to research, taking vitamin D3 (a form of vitamin D) daily can reduce the risk of death from cancer by 12%.
Vitamin D3 reduces cancer mortality by 12%
The study, conducted by the German Cancer Research Center in Heidelberg (Germany), analyzed 14 studies with nearly 105,000 participants.
Current studies suggest that vitamin D3 supplementation may not prevent cancer development, but may reduce the risk of cancer-related death, explains Dr. Ben Schöttker, an epidemiologist at the German Cancer Research Center.
However, previous studies have produced very different results and we wanted to clarify this issue by reviewing all previous studies on this topic.
When evaluating the studies, researchers focused on people who had received vitamin D3 injections.
When dividing the studies by whether they used low-dose daily vitamin D3 (400 to 4,000 IU per day) or high-dose long-term vitamin D3 (60,000 to 120,000 IU once a month or less), there was a big difference.
Fatty fish is the best source of vitamin D3
The authors found that 10 out of 14 studies showed that vitamin D3 reduced cancer mortality by 12%.
"We observed a 12% reduction in cancer mortality after vitamin D3 supplementation," said Mr Schöttker, according to Express .
More detailed analysis also found that people aged 70 and over benefited most from vitamin D3 therapy.
The effect is strongest when vitamin D supplementation is started before cancer diagnosis.
Dr Hermann Brenner, professor of epidemiology and prevention expert at the German Cancer Research Center, added: “This work highlights the huge potential of using vitamin D3 in preventing cancer deaths, according to Express .
According to the medical news site WebMD , vitamin D3 is mainly found in salmon, sardines, eggs, and beef liver. Of these, fatty fish is the best source of D3.
