Vitamin D is best known for keeping your bones healthy, but over the years, it's also become a topic of discussion in cancer research. You may have heard that having enough vitamin D could lower the risk of breast cancer, which is backed by evidence. Before adding another supplement to your routine, it's worth understanding what researchers have found and where evidence still falls short
Why is vitamin D being studied?
Vitamin D does more than help your body absorb calcium. It also plays a role in how cells grow, divide, and repair themselves. Because of this, researchers have been looking at whether vitamin D might influence the way breast cancer develops. As breastcancer.org shows, low vitamin D levels are linked with a higher risk of several diseases, including diabetes, osteoporosis, and breast cancer.
What if you're low in vitamin D?
Vitamin D deficiency is fairly common, particularly in those who do not get much sunlight or people with certain medical conditions. If blood tests indicate low vitamin D levels, your doctor might recommend taking a supplement. While it's important to correct a deficiency, it is not a breast cancer prevention measure. The recommended dose of vitamin D varies with your age, health status, and current vitamin D levels, so don't just assume the dose without checking with your healthcare provider.
Can you get enough through food and sunlight?
For many, the answer is yes. Your body makes vitamin D when your skin is exposed to sunlight. Alternatively, it can be obtained from:
Fatty fish – salmon and sardines
Egg yolks
Milk and cereals that are fortified
Mushrooms after exposure to ultraviolet light
If these sources aren't enough, your doctor may suggest a supplement after checking your vitamin D levels.
What should you take away?
Vitamin D serves many functions in the body, an its is beneficial to maintain it in a healthy range. But based on the research we know today, taking extra vitamin D hasn't been proven to prevent breast cancer. Don't just take a supplement; rather, pay attention to what is known to help maintain breast health. Stay active, keep a healthy weight, and avoid alcohol.
