Broccoli Extract

Ingredients A-Z

Overview

Broccoli extract, derived from Brassica oleracea is a cruciferous vegetable celebrated not only for its nutritional value but also for its potent health-promoting phytochemicals. Broccoli extract is a concentrated form derived primarily from broccoli florets or seeds and is particularly rich in a bioactive compound called sulforaphane, a powerful isothiocyanate formed when the enzyme myrosinase acts on glucoraphanin (a glucosinolate found in broccoli). Sulforaphane has been the subject of extensive scientific research due to its wide-ranging effects on detoxification, inflammation, oxidative stress, and cellular protection¹. Broccoli extract is often used in functional foods, dietary supplements, and nutraceuticals for its potential to support detoxification, antioxidant defense, cellular health, and hormonal balance.

Key indications

Detoxification

Broccoli extract is a well-established phase II detoxification enzyme inducer, promoting the elimination of
environmental toxins, carcinogens, and xenobiotics. It does this by activating the Nrf2 pathway, which increases expression of protective enzymes like glutathione S-transferase (GST) and NAD(P)H quinone oxidoreductase². Broccoli extract was shown to upregulate genes related to detoxification and glutathione synthesis in the liver, which support in liver detoxification³.

Detoxification

Supports Cellular Health

Broccoli extract supports healthy cell function and may reduce abnormal cell growth by inducing apoptosis in damaged cells, supporting DNA repair, and inhibiting angiogenesis⁸. This makes it a valuable adjunct in cellular protection strategies. Studies suggest that broccoli extract, through its bioactive compounds like sulforaphane, can play a significant role in promoting cellular health by enhancing detoxification processes, reducing oxidative stress, and supporting organ function⁹.

Adverse effects

Daily consumption of approximately 400mg of broccoli extract has not been associated with serious adverse effects. However, intake exceeding 400mg may cause minor gastrointestinal issues such as gas, bloating, or cramps¹⁰.

Dosage range

There is no established recommended dosage or upper limit for broccoli extract. Some studies have shown that it can be safely consumed at doses ranging from 100mg to 400mg daily13.

Contraindications/cautions

Blood Thinners
Broccoli extract contains vitamin K, which can affect blood clotting. Individuals taking blood thinners such as warfarin should be cautious, as it could interfere with the medication’s effectiveness¹¹.

Thyroid
Broccoli extract contains goitrogens, which can interfere with thyroid hormone production. Individuals with thyroid conditions, especially hypothyroidism, should be cautious and may need to moderate their intake¹⁰.

Insufficient reliable information regarding the use of broccoli extract for children, pregnancy and lactation¹².
