Vitamins for Cancer - What Really Works? Pharmacists Talk

What are some vitamins for cancer prevention and treatment that people are using?

Many vitamins and minerals play a critical role in regulating cell function.

Hence, experts know that they can have significant effects on cell growth.

Recall that cancer is a condition where normal body cells grow (that is reproduce) out of control.

As for taking supplements for cancer, we would like to point that there are no vitamin that clearly shows that they will prevent, let alone treat, cancer in.

Most of the studies are suggestive of their benefits in the fight against cancer (and some are highly suggestive indeed).

But the larger studies done show conflicting results. (Some studies show that certain vitamins seem to help and other studies show that it doesn't.)

Find out what these vitamins are in your fight against cancer...

Vitamins for Cancer Patients

Here is a list of commonly used vitamins for the prevention and treatment of various types of cancer as suggested by experts in the field of alternative and complimentary medicine.

Vitamin D

Many large population studies show a strong relationship between high vitamin D levels and the risk of developing various types of cancer.

The benefits of vitamin D in cancer prevention seem to be greater in men than women.

Many pharmacists and doctors are suggesting that practically everyone take at least 1,000 IU daily of vitamin D.

Forget about exposing your skin to sunlight for it to make vitamin D! Do you really want to increase your chance of getting skin cancer?


Selenium levels in the blood seem to show a strong relationship to the risk of developing cancer. In one population study, those who live in areas with high amounts of selenium showed lower risk of cancer cases.

Check the multivitamin that you currently take. Many brands will have about 100 to 200 mcg (micrograms) of selenium in them.

Vitamin C

Practically everyone has heard of taking vitamin C for curing the common cold. This is still a controversial topic today, although current studies show very limited health benefits of vitamin C against the common cold.

High doses of vitamin C have been studied in the treatment of cancer. Population studies have shown a link between high levels of vitamin C and lowered risk of developing colon, lung, prostate, stomach and mouth cancer.

However, these results are only suggestive and do not show a direct cause and effect relationship. It is known also that a diet high in fruits and vegetables, a good source of vitamin C, is linked to a lower risk of many times of cancer.

Ultra-high doses of vitamin C for cancer treatment must be given intravenously to avoid side effects.

Mega dose vitamin C therapy may hold some promise in the treatment of cancer but there are conflicting results.

Vitamin E

Vitamin E is a major anti-oxidant in our body and it works to reduce the amount of free radical which can damage cells leading to cancer.

One study, for example, showed that bladder cancer risk is reduced with long term use of vitamin E.

Folic Acid

Some studies have shown a link between folic acid and the risk of lung cancer (in smokers) and cervical cancer. Avoid deficiency by taking 0.6 to 1 mg daily.

Read the label on the multivitamin bottle. Most of them will have at least 0.4 mg to 0.6 mg.


Zinc is a trace mineral that seems to be linked to the risk of prostate cancer but this is still unclear.

It is suspected to be helpful in men with an enlarged prostate.

Calcium and Magnesium

Many people know that calcium is good for the bones, but did you know that it has been shown to be useful in reducing the risk of bowel cancer?

Make sure you get around 1,500 mg of calcium daily from either your diet and/or a calcium and magnesium supplement.

Treating cancer is a complex undertaking and requires constant monitoring. It is essential that you are under the care of a competent health care professional.

Bottom Line

Looking for vitamins that may be helpful in the fight against cancer?

In addition to various herbs, vitamins are also useful for patients suffering from cancer. However, there is little evidence that vitamins alone would help fight off cancer.

Do not expect any miracles or magical cures. And if anyone suggest that there is such a cure, be very skeptical.

Cancer is a very complex health condition for which even the best experts in the world do not fully understand how the cells work.

It is very important you are under the care of a competent experts skilled in the treatment of cancer conditions.

Different experts will not necessarily agree on which supplement is best for your specific type of cancer.
