Organic Brussels sprouts are a cruciferous vegetable that deliver glucosinolates, sulfur compounds, and vitamin K. People eat them cooked or raw as part of a vegetable-rich diet. No standard supplemental form exists.
Their fiber supports digestive health and their compounds bolster antioxidant defenses. Cooking or fermenting reduces the goitrogenic content. Eating exceptionally large amounts raw can interfere with thyroid function over time.
Anyone taking blood-thinning medications like warfarin should keep vitamin K intake steady. This entry covers the whole food only, not an extract or capsule.
