Broccoli Sprout

Reviewed on 6/11/2021
Other Name(s):

Asparkapsas, Brassica oleracea, Brassica Oleracea Italica Group, Brassica oleracea var. italic, Brecol, Brocoli, Brócoli, Brocolos, Broculos, Brokkoli, Cavolo Broccoli, Chou Broccoli, Parsakaali, Sprouting Broccoli.


Broccoli sprout is a young broccoli plant. Compared to mature broccoli, broccoli sprout contains more sulforaphane. Sulforaphane is a chemical that is thought to have health benefits. Whole broccoli sprouts or broccoli sprout extracts are used as medicine.

Broccoli sprout is taken by mouth for allergy, asthma, cancer, and stomach ulcers caused by the bacteria Helicobacter pylori.

Broccoli sprout extract is applied to the skin to prevent sunburn.

How does it work?

When taken by mouth, broccoli sprout reduces the ability of H. pylori to infect the stomach. It also appears to decrease the release of proteins that cause stomach swelling.

When applied to the skin, broccoli sprout increases the amount of protective proteins in the skin.

Uses & Effectiveness

Insufficient Evidence to Rate Effectiveness for...

  • Helicobacter pylori (H. pylori) Early research suggests that eating broccoli sprout (Broccoli Super Sprout, Murakami Farm) for 8 weeks decreases markers of stomach swelling and levels of H. pylori in people with H. pylori infection. However, levels of H. pylori appear to increase after treatment is stopped. This suggests that broccoli sprout reduces but does not eliminate H. pylori infection.
  • Sunburn Early research suggests that applying broccoli sprout extract to the skin once daily for 3 days before exposure to ultraviolet (UV) radiation reduces sunburn by about 8% to 78%.
  • Allergy.
  • Asthma.
  • Cancer.
  • Other conditions.
More evidence is needed to rate the effectiveness of broccoli sprout for these uses.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).

Side Effects

Broccoli sprout is LIKELY SAFE to eat in amounts commonly found in food, as long as the broccoli sprouts are grown according to FDA guidelines. Side effects of eating properly grown broccoli sprouts have not been reported.

Broccoli sprout extract is POSSIBLY SAFE to take by mouth for up to 7 days. There isn't enough information to know if it is safe to use broccoli sprout extract for longer periods of time.

Eating broccoli sprouts that have not been grown properly is POSSIBLY UNSAFE. Broccoli sprouts can be contaminated with bacteria if not grown properly. Eating contaminated broccoli sprouts might cause food poisoning.

Special Precautions & Warnings

Pregnancy and breast-feeding: It's LIKELY SAFE to eat broccoli sprout while pregnant, provided the broccoli sprouts are cooked. However, raw broccoli sprouts are LIKELY UNSAFE when eaten during pregnancy. Raw broccoli sprouts might be contaminated with bacteria that can cause food poisoning. Food poisoning during pregnancy might cause miscarriage, premature birth, or stillbirth. Stay on the safe side and eat only cooked broccoli sprouts while pregnant.

Broccoli sprouts are LIKELY SAFE to eat while breast-feeding, provided the broccoli sprouts are cooked. But it's POSSIBLY UNSAFE to eat raw broccoli sprouts due to the risk of food poisoning. Stay on the safe side and eat only cooked broccoli sprouts while breast-feeding.

It is not known if it is safe to use broccoli sprout extract while pregnant or breast-feeding.

Low immune system function: Raw broccoli sprouts can be contaminated with bacteria. People who have low immune system function might be more likely than other people to develop food poisoning after eating contaminated raw broccoli sprouts. Advise people with low immune system function to avoid eating raw broccoli sprouts.


The appropriate dose of broccoli sprout depends on several factors such as the user's age, health, and several other conditions. At this time, there is not enough scientific information to determine an appropriate range of doses for broccoli sprout. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
