10 Proven to Work Supplements to Fight and Prevent Cancer

In the quest for better health, many people are exploring natural ways to reduce the risk of cancer. While no supplement can completely prevent or cure cancer, research suggests that some can play a supportive role in strengthening the body’s defenses. From powerful antioxidants to anti-inflammatory nutrients, certain supplements may help lower the risk of developing cancer or support your body in its fight. Here, we explore 10 supplements that have shown potential in this area and how they might fit into a healthy lifestyle.

1- Glutathione (GSH)

Glutathione is the most important antioxidant produced by your body and a master detoxifier of every cell in your body.

glutathione plays a protective role in our bodies. As it can protect healthy cells from free radicals and peroxides which can cause cancer mutation. Therefore, It is crucial in the removal and detoxification of carcinogens.

Many studies have looked specifically at people with glutathione deficiency and found that low levels of GSH within normal healthy cells make them more vulnerable to cancer.

Also, studies have identified over 60 diseases that have low glutathione levels as one of their characteristics.

So supplementing with glutathione will not only protect you against cancer, but also it will keep you away from 59 other diseases.

*The recommended daily dosage of Glutathione to prevent cancer is 50 mg.

2- Melatonin

Melatonin is a hormone that is secreted by the pineal gland. The pineal gland and melatonin help to modulate the body’s internal clock, allowing the body to know what time of day it is and regulate the body’s sleep cycle.

But it’s also a tumor suppressor and protector from many kinds of cancer, including breast cancer.

Renowned cancer researcher Dr. David E. Blask found that melatonin has the ability to suppress breast cancer growth. He discovered that nighttime melatonin levels in the blood can slow breast cancer growth by 70%!

Also, melatonin can help those suffering from breast cancer. Because melatonin reduces oxidative stress, according to a 2011 Indian study.

As for cancer prevention, Melatonin boosts the immune system as it’s a natural antioxidant and can enhance the production of T-helper cells in the body to fight the formation of cancer cells.

If you are someone with low melatonin levels, there are synthetic and natural melatonin supplements that can protect you against cancer and also help you get more sleep.

*The recommended daily dosage of Melatonin to prevent cancer is 10-40 mg.

3- Omega-3

Omega-3’s are fatty acids found in foods, such as fish and flaxseed, and in dietary supplements, such as fish oil supplements

The three main omega-3 fatty acids are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA).

-(ALA) is found mainly in plant oils such as flaxseed, soybean, and canola oils.

-(DHA) and (EPA) are found in fish and other seafood.

Omega-3 fatty acids are thought to reduce inflammation in the body. A variety of cancers have been linked to chronic inflammation, including Colorectal, Liver, Lung and Prostate.

Omega-3s also seem to restrict tumor cell growth and may cause cancer cells to self-destruct.

So, experts suggest that omega-3 supplements can have an effect on preventing cancer formation and limiting its growth.

*The recommended daily dosage of Omega-3 to prevent cancer is 200-4,000 mg.

4- Garlic Ext ract

Garlic is a great choice when it comes to giving your body a little extra protection.

Protective effects may include:

Antibacterial properties.
Blocking and halting the activation of cancer-causing substances.
Enhanced DNA repair.
A reduction in cancer cells spreading.

Several population studies show an association between increased intake of garlic and reduced risk of certain cancers, including cancers of the stomach, colon, esophagus, pancreas, and breast.

Garlic supplements can be classified into four groups: Garlic essential oil, garlic oil macerate, garlic powder, and garlic extract.

Any form of garlic supplement has some benefits, but the most effective form in fighting cancer is garlic extract.

*The recommended daily dosage of Garlic Extract to prevent cancer is 600-1.200mg.

5- Resveratrol

Resveratrol is a nutrient present in grape skins. It is synthesized in grapes to help protect against physical harm, infection, and disease. Interestingly, it helps to protect us as well!

Resveratrol is a powerful antioxidant classified as a polyphenol and is the primary active compound associated with anti-aging.

Resveratrol has been shown to suppress nuclear factor Kappa Beta (NF-KB). NF-KB is a master inflammation-causing agent that promotes cancerous growth in tissue.

It acts on NF-KB by inhibiting its activity as well as allowing for the normal processes of the immune system to trigger cell death (apoptosis).

HRB-beta 1 (Heregulin-Beta1) is a pathway that gives signals to the cells.

Abnormal activation in HRB-beta 1 has been implicated in activating cancer growth in the breasts.

Resveratrol has been shown to stop this pathway and prevent breast cancer. Evidence from other studies provides support that it may also be linked to the prevention of cancerous pathways in the pancreas, skin, liver, colon, prostate, and many other cancer types.

Many people think they can get enough resveratrol from drinking wine or eating grapes. But they only have small amounts of resveratrol.

It would take 41 glasses of red wine in order to get up to the minimum dosages that are clinically effective.

*The recommended daily dosage of Resveratrol to prevent cancer is 100 to 200 mg.

6- Green tea extract

Green tea has an anti-cancer effect due to the presence of substances called polyphenols.

Laboratory studies of one polyphenol called (EGCG), show that it may interfere with several of the processes involved in cell replication, causing tumor cell death (apoptosis). It also might slow the formation of blood vessels around tumors.

Epigallocatechin (ECG), another polyphenol found in green tea, stops leukemic cells (blood cancer) from multiplying in laboratory studies.

As a proven antioxidant, green tea may repair cell damage and prevent free radical damage.

To protect yourself from cancer, consider drinking 3-5 cups of green tea daily or just take a green tea supplement to make it easier for you.

*The recommended daily dosage of Green tea to prevent cancer is 200 mg or higher.

7- Selenium

Selenium is a powerful mineral. Needed only in very small amounts, it plays a crucial role in your cells’ defenses against cancer.

It removes free radicals from the body, making it a potential defense against it. It also plays a role in recycling antioxidants through the body. These antioxidants, such as vitamin E.

Selenium may also protect the body against contaminants such as mercury, cadmium, and silver, help speed the elimination of it’s cells and slow tumor growth.

Studies have shown that selenium intake above the recommended dietary allowance (RDA) may protect against certain cancers.

In one region of China, where epidemic rates of esophageal and gastric cancers occurred, the risk was cut in half after large doses of selenium were given.

Selenium supplements may also be able to halt the growth of polyps in the colon and reduce the risk of lung and liver cancers.

*The recommended daily dosage of Selenium to prevent cancer is 200-400 micrograms (mcg).

8- Curcumin

Curcumin is a substance found in the spice turmeric. It has long been used in Asian medicine to treat a variety of maladies. Now, some research suggests that curcumin may help prevent or treat cancer.

Laboratory and animal research suggests that curcumin may prevent cancer, slow the spread of it, make chemotherapy more effective and protect healthy cells from damage by radiation therapy.

Curcumin is thought to have antioxidant properties, which means it may decrease swelling and inflammation.

The benefits of curcumin may include:

Blocking cancer cells from multiplying.
Killing colon, breast, prostate, and melanoma cells.
Slowing tumor growth.

Add some turmeric to your next dish, or take a supplement containing curcumin to experience the benefits of this powerful substance.

*The recommended daily dosage of Curcumin to prevent cancer is 500 milligrams (mg).

9- Vitamin D

Vitamin D helps the body absorb calcium and phosphorus to make strong bones and teeth. Skin exposed to sunshine can make vitamin D, and vitamin D can also be obtained from certain foods.

Vitamin D deficiency may cause disorders associated with weak bones. However, some evidence has emerged suggesting that vitamin D may be associated with other diseases, including bowel and lung cancers.

According to BreastCancer.org, research suggests that certain cancers such as breast cancer, can have a higher risk of occurring when the body has low levels of vitamin D.

*The recommended daily dosage of Vitamin D to prevent cancer is 1100 IU.

10- Vitamin E

Vitamin E is an excellent cancer-fighting nutrient. Vitamin E is fat-soluble and acts as a strong antioxidant, helping the body remove cell-damaging free radicals.

In lab research, they have found that vitamin E prevents cancer, at least for certain patients. Among people with the genetic disorder Cowden Syndrome, vitamin E may slow or stop the cell damage that leads to it.

Also, vitamin E can significantly decrease the risk of prostate, colon, and lung cancers. In fact, low amounts of vitamin E may increase the risk of cancer. It’s important to get enough of this vitamin daily from diet or supplements.

*The recommended daily dosage of Vitamin E to prevent cancer is 8 to 15 mg.
