Swanson Brassica & Greens
Swanson's Brassica & Greens formula is one of the most affordable dedicated cruciferous vegetable supplements available. It combines broccoli, cauliflower, Brussels sprouts, and kale concentrate in a simple capsule format without unnecessary additives. While it doesn't have the marketing budget of premium brands, independent quality testing confirms it delivers what the label claims. An excellent starting point for budget-conscious shoppers.
From broccoli blends to full-spectrum cruciferous greens powders, these supplements deliver the cancer-fighting, detox-supporting power of your least-eaten vegetables in convenient daily servings.
Cruciferous vegetables are among the most nutrient-dense foods available, but most people eat far fewer of them than research suggests is beneficial. Supplements that concentrate broccoli, kale, cauliflower, and related vegetables offer a convenient way to maintain consistent intake of glucosinolates, sulforaphane, and other brassica-specific compounds. This list focuses on products that go beyond single-compound DIM supplements to deliver the broader nutritional profile of cruciferous vegetables.

Swanson Brassica & Greens
Swanson's Brassica & Greens formula is one of the most affordable dedicated cruciferous vegetable supplements available. It combines broccoli, cauliflower, Brussels sprouts, and kale concentrate in a simple capsule format without unnecessary additives. While it doesn't have the marketing budget of premium brands, independent quality testing confirms it delivers what the label claims. An excellent starting point for budget-conscious shoppers.
Amazing Grass Green Superfood
Amazing Grass includes a meaningful cruciferous vegetable base (wheatgrass, kale, broccoli, alfalfa) alongside alkalizing greens, prebiotics, and probiotics. The powder format mixes well with water or smoothies and has a pleasant flavor compared to many greens products. It's not a pure cruciferous supplement, but it delivers a solid dose of brassica compounds alongside broad-spectrum micronutrients.
Garden of Life Raw Organic Perfect Food
Garden of Life's Perfect Food is a certified organic, raw greens powder that emphasizes whole-food ingredients including kale, broccoli, spinach, and a range of other vegetables. The raw processing preserves natural enzymes, and the formula includes a digestive enzyme and probiotic blend. It's one of the most whole-food-aligned cruciferous vegetable supplements on the market.
Nested Naturals Super Greens
Nested Naturals has built a strong following for transparent labeling and third-party testing. Their Super Greens formula leads with spirulina and chlorella but includes a robust cruciferous blend featuring kale, broccoli, and spinach. The company publishes Certificate of Analysis documents for every batch, which is an above-average commitment to quality transparency.
Athletic Greens AG1
AG1 is the premium option in this category, combining 75 ingredients including a substantial cruciferous and phytonutrient complex alongside vitamins, minerals, adaptogens, and digestive support. The formula includes broccoli flower, brussels sprout, and other brassica extracts as core components of its nutrient dense base. The price is significantly higher than other options, but the comprehensiveness and quality assurance are unmatched.
Before you buy
Form factor
affects consistency. Capsules are the most convenient for daily use; powders allow larger serving sizes and can be mixed into meals, but require more discipline to use consistently.
Whole food vs. extract
is a meaningful distinction. Whole-food blends (Garden of Life) preserve natural enzyme activity and co-factors. Extract-based products (Swanson) deliver higher concentrations of specific compounds but may sacrifice some synergistic micronutrients.
Certification
matters at this price range. Look for USDA Organic, Non-GMO Project Verified, or NSF/USP certification to confirm that what's on the label is in the bottle.
Fiber content
differentiates whole-food supplements from extracts. If digestive support is part of your goal, choose a powder-based whole-food product over a capsule extract.

Quick answers
Standard greens powders prioritize a broad spectrum of vegetables and algae. Cruciferous-specific supplements concentrate on broccoli, kale, cauliflower, Brussels sprouts, and similar brassica vegetables, delivering higher doses of glucosinolates, DIM, and sulforaphane.
Supplements are best used as a complement to a diet that includes some whole cruciferous vegetables. Whole foods provide fiber and additional micronutrients that extracts cannot fully replicate, but a quality supplement can meaningfully close the gap on active compound intake.
Most users report subtle improvements in digestion and energy within 2-4 weeks. Hormonal and detoxification benefits typically require consistent use of 6-12 weeks to become noticeable, as these are systemic adaptations rather than acute effects.
