Sulforaphane Supplements: Defination, Benefits, Side Effects &
Food Source
1. What is sulforaphane?
Sulforaphane (SFN) is a compound rich in sulfur that is found in cruciferous vegetables such as cabbage,
broccoli, and bok choy. Sulforaphane products have been proved to offer you powerful health positive
effects. In these foods, sulforaphane is found in an inactive form called glucoraphanin which belongs to
the plant family of glucosinolate compounds.
Sulforaphane and glucoraphanin
Sulforaphane (SFN) is activated when glucoraphanin gets into contact with myrosinase. Myrosinase is a
family of enzymes that play a major role in the plant’s defence response. These enzymes are only

produced and stimulated when a crop is damaged. As a result, cruciferous vegetables should be chopped,
cut, or chewed in order to release myrosinase and stimulate sulforaphane.
Sulforaphane and glutathione
Sulforaphane blocks Primary Human T-Cell’s inflammatory responses by depleting Glutathione and
Increasing ROS. That’s basically how sulforaphane and glutathione relate. The function and action of
T-cells are influenced by the extra- and intracellular redox milieu.
In a study to investigate how sulforaphane affected the health of the liver, Sulforaphane and
glutathione were seen to interact to cause positive effects in the liver health of rats. Broccoli sprouts
were seen to activate glutathione production and detoxification, boosting GST while lowering ALT and
AST in the livers of rats.
2. How does sulforaphane work?
Sulforaphane has been shown to cause cancer prevention effects by stimulating a transcription factor
known as Nrf2 (nuclear factor (erythroid-derived 2)-like 2). Nrf2 regulates the balance of oxidation by
reducing oxidation in your body cells, and by improving the anti-oxidation ability of your body. Nrf2
when stimulated also increases the ability of your body to detoxify chemical compounds taken into your
body.
It is known that a reduction in the balance of oxidation due to obesity and hyper nutrition may lead to
several diseases. Sulforaphane works to enhance the balance of oxidation and also downregulates
obesity and hyper nutrition. By so doing, sulforaphane is able to protect the body against several other
diseases.

3. Sulforaphane benefits?
Sulforaphane benefits results from the ability of sulforaphane to regulate the balance of oxidation. It
does so by decreasing oxidation in the cells, and by increasing the anti-oxidation ability of your body.
Sulforaphane benefits therefore include;
 Aiding Weight Loss
 Fighting Cancer Cells
 Kills Toxins
 Improves the Health of The Heart
 Have Powerful Antiviral Activities
 Fights Diabetes
 Improves the Brain Function
 May Lower Constipation
 Decreases Symptoms of Autism
 Improves the Functioning Of the Liver
 Improves the Health of the Eyes
 Improves Brain Function

Now let’s discuss the above functions in details;
I. Weight loss
A diet rich in vegetables is one of the most obvious suggestions for weight loss. Vegetables are
generally high in nutrients and low in calories and are considered crucial to a healthy lifestyle.
Sulforaphane contributes to weight loss by reducing the amount of visceral fat. Sulforaphane
supplements also increases browning of adipose tissue stimulating burning of more fat.
SNF also lowers the level of cholesterol, liver triglyceride, and improves glucose tolerance and insulin
resistance. In simpler terms, sulforaphane fights obesity by changing your body’s energy consumption
and by improving gut flora.
II. Sulforaphane Fights cancer cells
It is important to know that brassica vegetables assist in protection against cancer. Eating just three to
five servings per week lowers risk of cancer by 30 to 40 percent. This great decrease in the risk of
cancer is the main reason why you need to take these vegetables daily. However, there are many other
cancer-protective advantages as well.
Sulforaphane fights cancer cells while strengthening healthy mitochondria at the same time. Also,
sulforaphane powder detoxifies carcinogens and destroys cancer cells. SFN also prevents against the
growth of tumour. Research has shown that sulforaphane assists in destroying cancer in men, too.
The results of sulforaphane powder in cancer treatment are so highly promising that drug companies are
testing Sulforadex drug, for its use in the treatment of cancer. Sulforadex drug is a synthetic form of
sulforaphane.
III. Sulforaphane antioxidant kills toxins
Phytochemicals such as sulforaphane are powerful antioxidants. Sulforaphane antioxidant is very
effective in destroying free radicals. Free radicals are small particles that damage and weaken healthy
cells. They normally form in our bodies because of various factors. This factors include pollution, food

5
additives, UV rays, and preservatives. Free radicals may also form through natural processes such as
digestion.
IV. Sulforaphane improves the health of the Heart
Sulforaphane may improve the health of your heart in several ways.
For example, sulforaphane may help improve the health of your heart by lowering inflammation.
Inflammation can cause narrowing of arteries which is one of the major causes of heart disease.
Sulforaphane broccoli powder may also lower high blood pressure. Reducing high blood pressure may
prevent you from heart diseases.
V. Sulforaphane Shows Powerful Antiviral Activities
Sulforaphane broccoli powder has shown powerful antiviral activities when cells which are infected are
directly exposed. However, there is no enough evidence currently to support its application in people
with viral infections.
Sulforaphane broccoli powder lowers influenza viral load. Taking sulforaphane products also improves
the antiviral action of immune cells in human beings.

VI. Sulforaphane Shows Diabetes Fighting Effects
Type II diabetes is one of the most common chronic diseases affecting many people worldwide.
People with type II diabetes cannot transport sugar from their blood effectively to their cells. This
makes it extremely hard to maintain a healthy blood sugar level.
Sulforaphane lowers the levels of fasting blood sugar effectively by 6.5 per cent. The positive effects
are specifically stronger in people who are overweight.
Sulforaphane benefits on the control of blood sugar levels are also supported by several animal studies.
VII. Sulforaphane Improves Our Brain Function
Sulforaphane is also excellent for the brain. It is one of the most popular a nootropic because it can
cross the blood-brain barrier.
Sulforaphane powder has been seen to help the brain in animals in several ways. To start with, the
intake of glucoraphanin myrosinase during the adolescent and juvenile periods prevented against the
start of cognitive deficits in adulthood.

Glucoraphanin blocked brain swelling in mice, reducing pro-inflammatory cytokines levels.
Glucoraphanin myrosinase also prevented against impairment of memory in diabetic mice.
Glucoraphanin myrosinase provided protection against brain damage caused by acute CO poisoning in
mice.
In cell research, Sulforaphane powder also provided protection to neurons from humans against
prion-mediated neurotoxicity.
VIII. Sulforaphane Improves The Health of Our Eyes
Excessive light exposure may lead to oxidative stress which can cause several human retinal disorders
by increasing the death of photoreceptor cells. A photoreceptor is a cell that receives light and translates
it into a nerve impulse.
Sulforaphane protects human retinal cells against induced damage by UVA light. Treatment by
Sulforaphane significantly lowered ischemia (lowered blood and oxygen flow.) This condition causes
loss of retinal functionality in humans.
Sulforaphane protected lens cells in humans against oxidative stress. Furthermore, Sulforaphane may
assist in prevention against complications after cataract surgery.
IX. Sulforaphane Improves the Functioning of the Liver
In humans with fatty liver, sulforaphane products enhances the functioning of the liver and lowered
γ-GTP, ALP, and ALT. In animals, glucoraphanin protected against a broad variety of liver illnesses
caused by high-calorie diets, toxic chemicals, alcohol, and drugs.
Several drugs such as sodium valproate may cause toxicity in the liver. In mice, glucoraphanin
myrosinase significantly enhanced the functioning of the liver lowered ALP, ALT, and AST. This
compound also improved valproate-induced damage of the liver.
X. Sulforaphane Supplements Decreases symptoms of autism

Placebo-controlled, double-blind research in men with autism found that SFN supplements lowered
autism symptoms. These symptoms include hyperactivity, lethargy, stereotypy, and irritability.
Participants consumed the equivalent of several servings of broccoli per day. This amount worked well
for them.
XI. Sulforaphane May Lower Constipation
Taking 20 grams of broccoli sprouts per day lowers the symptoms of constipation in people suffering
from the same.
4. Sulforaphane side effects
Sulforaphane side effects are clearly not one of the most important concerns that you should consider
before taking SFN. Taking sulforaphane dosage in amounts equal to what is present in cruciferous
vegetables is safe. Such an amount shows very few if any sulforaphane side effects.
Also, sulforaphane powder bulk amounts are available for sale at various websites and health food
stores as supplements or for use in research and drug development. These sulforaphane products are
also considered safe.
These sulforaphane supplements are always extracted from broccoli sprout and are always concentrated,
meaning that they contain more SFN than what is found in food naturally.
Glucoraphanin which is the precursor to SFN is also available in the form of supplements combined
with myrosinase for activation. Glucoraphanin myrosinase is marketed as a way of boosting production
of sulforaphane in the body. This combination doesn’t show any serious side effects too.
While we have no sulforaphane dosage clinical recommendations, most supplement brands recommend
taking around 400 mcg daily. This typically equals to one to two capsules.
However, mild sulforaphane side effects have been seen. They include:
 Diarrhea
 Constipation

 Increase in gas
5. Where can you find sulforaphane?
Broccoli and other cruciferous vegetables are very rich in sulforaphane. SFN is very effective when
broccoli is sprouting before maturing into the plant you normally see in your grocery shop. Activated
Sulforaphane Supplements are also rich in SNF. In summary, listed below are the food sources of
sulforaphane:
 Activated Sulforaphane Supplements
 Broccoli Sprouts
 Cauliflower
 Kales
 Other Brassicas such as Brussels sprouts and cabbages
6. Sulforaphane Supplements
If you don’t have the time to get your sulforaphane dosage from natural foods, SFN supplements are an
easy and quick way to acquire your daily dose of this important phytochemical. Sulforaphane

Supplements are usually extracted from broccoli sprouts and are usually concentrated to ensure they
have more SFN phytochemical than what you can get from food naturally.
The estimated Sulforaphane Supplement dosage in humans is:
 11 to 57 mg for a person weighing 250 lb
 9 to 45 mg for a person weighing 200 lb
 7 to 34 mg for a person weighing 150 lb
To make sure you get your quick sulforaphane dosage, you can look for sulforaphane supplements in
online sellers, health food stores, or from our website.
7. Where to buy sulforaphane powder?
If you are looking to buy sulforaphane powder, look for a certified manufacturer who has the knowledge,
expertise and the high-end equipment needed in the production of high-quality phytochemical
compounds. You should make sure that you’re sourcing sulforaphane powder from a trustworthy and
reputable seller to avoid buying a low-quality product.
You can also order sulforaphane powder from us for your research or supplement production. We have
the ability to process sulforaphane powder bulk orders quickly and deliver to the U.S., Europe, Asia,
and several other parts of the globe.
8. Sulforaphane VS glucoraphanin
Glucoraphanin is basically defined as the precursor to sulforaphane. Sulforaphane, on the other hand, is
an effective natural inducer of Phase II detoxification enzymes, which destroys several types of
environmental pollutants, free radicals, and trigger continuous antioxidant actions.
Myrosinase enzyme is needed to aid in the conversion of glucoraphanin to sulforaphane. Also, there’s
scientific evidence that supports sulforaphane production from glucoraphanin by gut microflora,
New research from Johns Hopkins University School of Medicine shows that sulforaphane
bioavailability from commercial glucoraphanin supplement is equal to that seen in broccoli sprouts,
