Vitamins are essential for your body to function properly. They help you perform daily activities, fight off infections and stay healthy. But not all vitamins are created equal.
The best vitamin to take depends on what you’re trying to achieve. Here’s an overview of the best vitamins for cancer, including vitamins A, C and D.
Vitamin A is a fat-soluble vitamin that plays a role in cell growth and repair throughout your body. It promotes healthy vision and supports the immune system.
Vitamin C is an antioxidant that protects cells from damage caused by free radicals. It also aids in tissue repair, boosts immunity and helps maintain a healthy heart, bones and teeth.
Vitamin D is produced when sunlight strikes your skin and helps regulate calcium levels in your body. Vitamin D also boosts bone health, lowers inflammation and may reduce the risk of certain cancers like colorectal cancer or breast cancer, according to one study published in Cancer Epidemiology Biomarkers & Prevention in 2010.
The best vitamins for cancer are high-quality, whole food-based supplements that support your body’s natural healing processes. While it’s true that many vitamins and minerals have been shown to help prevent and fight cancer, it’s important to understand that there is no one vitamin or mineral that is a magic bullet.

Cancer cells are complex and require the support of many nutrients in order to grow and spread. If you’re already taking a multivitamin or other supplement, talk with your doctor about adding some of these essential nutrients to your routine.
Best Vitamins for Cancer: An Overview
Vitamin C: Vitamin C has been shown to help prevent cell damage caused by free radicals and stress. It also helps produce collagen, which supports healthy skin, bones and gums.* Vitamin C can be found in fruits such as oranges, strawberries, kiwis and grapefruits; vegetables such as bell peppers and broccoli; tomatoes; citrus juices; green leafy vegetables like spinach; potatoes; cantaloupe; papaya; pineapple juice; rose hip tea (also known as hip tea); parsley; cauliflower; Brussels sprouts; watercress; kale
Vitamin C is a powerful antioxidant that can help your body fight cancer. Vitamin E is another antioxidant that may slow the growth of cancer cells.
Vitamin D is an important vitamin that helps the body fight infections and maintain bone health. It may also help prevent certain types of cancer.
Selenium is a mineral that works with vitamin E to protect cells from damage caused by free radicals (unstable molecules that damage cells).
Antioxidants are substances that help prevent cell damage caused by free radicals (unstable molecules that damage cells). They may also have other benefits such as reducing inflammation and lowering cholesterol levels.
Vitamin D has been shown to help fight cancer, and is also useful for preventing cancer. Specifically, it’s believed that vitamin D helps the body produce proteins that strengthen the immune system. The evidence is strongest for breast cancer, but other studies have suggested that vitamin D may also help prevent prostate cancer and colorectal cancers.
A study published in the Journal of Clinical Oncology found that women taking vitamin D supplements had a lower risk of developing breast cancer than women who didn’t take supplements. Another study found that men with higher levels of serum vitamin D were less likely to develop prostate cancer over a 15-year period than those with lower levels.
The National Cancer Institute recommends that people with a history of colon polyps or inflammatory bowel disease should talk to their doctor about taking vitamin D supplements, since they’re at higher risk of developing colon cancer. The NIH also recommends getting 600 international units (IU) per day as part of your diet if you’re older than 19 years old and not getting enough sun exposure.
Vitamin A
Vitamin A is an essential nutrient that helps your body maintain a healthy immune system. It also promotes healthy skin, eyes, hair and nails. Vitamin A may help prevent cancer by reducing cell growth and blocking the growth of new blood vessels that supply tumors with nutrients.
Vitamin C
Vitamin C is an antioxidant that has been linked to a reduced risk of some cancers. Vitamin C may also help protect against heart disease, stroke and cataracts.
Vitamin E
Vitamin E is another antioxidant that may help prevent cancer by promoting healthy cell membranes in your body’s cells, which can help prevent some types of cancer from developing. Vitamin E may also reduce your risk for heart disease.
There is no actual cure for cancer, as of now. But doctors and patients resort to medications and supplements to fight against the disease. There are different vitamins for different types of cancer. And the prescribed vitamins must be in huge quantities. The patient can’t just take one or even two pills a day. The immune system will respond to these vitamins, toxins and tumors only if you take large amounts those daily. These are the top 5 vitamins for cancer treatment .
Best vitamins for cancer
There are various forms of vitamins that you can opt for, based on the health concern in order to treat your cancer effectively. B-complex vitamins and vitamin C are a well were good starting point. Other than these vitamins, there are some other forms of vitamins that you can take internally to deal with your cancer.
You’ve picked the right site if you are looking for comprehensive guides on vitamins that help treat cancer – or prevent it. I was shocked to learn how easy it is to prevent this disease, yet so many of us don’t get the nutrition we need. Even worse, cancer is widespread -1 out of 2 men and 1 out of 3 women will get it in their lifetime.
It’s likely that you’ve heard, or even seen, an advertisement for GNC (or other vitamin stores) claiming that they carry the best vitamins and supplements on the market. In reality, not all supplements are created equal, which is why you must do your research before buying into these seemingly fantastic claims. Otherwise, you could wind up wasting a lot of money and even doing more harm to your body than good.
As the study below shows, certain fruits and vegetables have a high ORAC value. What is an ORAC value? Unlike phytochemicals, which take years to show positive health effects, antioxidant activity can be measured in minutes, which is why researchers use ORAC as a more accurate measure than phytochemicals. The higher the ORAC value means more antioxidant activity. For example, 1 serving of strawberries contains 625 ORAC U/100g, olives have 2036 U/100 g, dates have 587 U/100 g and mango has 838 U/100 g.
