Welcome to a proactive approach to lifelong health with Source Naturals Broccoli Sprouts Extract (Item #SN1105). Broccoli is widely praised as one of nature’s most powerful green superfoods, but young broccoli seedlings contain significantly higher concentrations of active phytonutrients than mature heads of broccoli.
Each 2-tablet serving delivers 500 mg of standardized sprouted broccoli extract blend, yielding 2,000 mcg of active sulforaphane. That is up to five times the amount found in an average serving of fresh grocery-store broccoli, giving you clean, concentrated cellular support without having to sprout seeds at home or consume massive heads of raw cruciferous vegetables every day.

How Sulforaphane Works: The Science of Cellular Detoxification
Unlike simple antioxidants like vitamin C or vitamin E that neutralize free radicals on a one-to-one basis and get used up quickly, sulforaphane acts as an indirect antioxidant. In simple terms, it acts like a master switch inside your cells.
When you take broccoli sprouts extract, sulforaphane activates a specialized protein pathway called Nrf2 (nuclear factor erythroid 2-related factor 2). Once activated, Nrf2 signals your DNA to produce your body’s own built-in internal defense network, known as Phase 2 detoxification enzymes. These include:
Glutathione S-Transferases (GST): Enzymes that bind toxic compounds and metabolic waste products to glutathione so your liver and kidneys can flush them out cleanly.
NAD(P)H Quinone Dehydrogenase 1 (NQO1): A protective enzyme that prevents reactive quinones from damaging cellular DNA.
Heme Oxygenase-1 (HO-1): An enzyme that helps manage oxidative balance and supports blood vessel lining integrity.
Because these enzymes regenerate and remain active for days, sulforaphane provides lasting cellular defense long after direct antioxidants have cycled out of your system.
Key Benefits of Source Naturals Broccoli Sprouts Extract
✓ Deep Liver & Toxin Cleansing
Helps the liver process airborne contaminants, processed food byproducts, and common environmental toxins by stimulating Phase 2 conjugation.
✓ Cellular DNA Protection
Shields delicate cellular structures and genetic material from day-to-day oxidative stress caused by ultraviolet light, stress, and pollution.
✓ Radiant Skin & Healthy Aging
By encouraging your body’s master antioxidant (glutathione) production, it supports skin vitality, elasticity, and cellular renewal from within.
✓ Guaranteed Potency Without the Mess
Sprouting broccoli seeds at home can be time-consuming and prone to bacterial contamination. Standardized tablets deliver reliable potency every time.
Scientific Evidence & Clinical Research Citations
The health properties of broccoli sprout extract are backed by decades of laboratory and clinical research from leading institutions:

Key Finding: Three-day-old broccoli sprouts were shown to contain 20 to 50 times the concentration of glucosinolate precursors found in mature broccoli heads.

Key Finding: In a randomized clinical trial, participants consuming broccoli sprout beverages showed immediate and significant increases in the urinary excretion of common environmental toxins like benzene (61% increase).

Frequently Asked Questions (FAQ)
What is sulforaphane and why are broccoli sprouts special?
Sulforaphane is a natural sulfur compound found in cruciferous vegetables. Broccoli sprouts are harvested when the seedling is just a few days old, a stage where glucosinolate concentrations can be 20 to 50 times higher than in mature broccoli florets. This provides a highly concentrated dose in a small serving.
How much sulforaphane does Source Naturals Broccoli Sprouts Extract contain?
Each 2-tablet serving contains 500 mg of standardized sprouted broccoli extract blend, which yields 2,000 mcg (micrograms) of active sulforaphane. This is up to five times the sulforaphane typically derived from a standard plate of fresh, cooked broccoli.
How should I take this supplement for best results?
The manufacturer recommends taking 2 tablets 1 to 2 times daily. Taking the tablets alongside meals can optimize natural digestive absorption and comfort.
Does this supplement contain common food allergens?
No. Source Naturals Broccoli Sprouts Extract is free of yeast, dairy, egg, gluten, corn, soy, wheat, sugar, starch, preservatives, artificial flavors, colors, and fragrances.
Can I take this supplement if I am pregnant or nursing?
If you are pregnant, planning to become pregnant, or breastfeeding, you should consult your physician or qualified healthcare provider before taking this or any dietary supplement.
