Publishes a third-party verified active number rather than only an extract weight: 50 mg of activated sulforaphane complex per serving, delivered in delayed-release beadlets rather than loose powder.
Sulforaphane glucosinolate paired with myrosinase and piperine in a 700 mg blend, so conversion does not rely solely on your gut bacteria. Two capsules per serving, 60 servings per bottle.
Broccoli seed extract combined with plant-derived myrosinase plus moringa leaf extract, in 120 vegan capsules. Worth knowing before you buy: the label does not publish a per-serving sulforaphane figure.
A plain high-count option: 1000 mg of broccoli sprout extract per capsule, 120 per bottle in a two-pack. No myrosinase and no sulforaphane standardization are stated, so conversion is left to your gut flora.
Standardized to 0.4% sulforaphane, which is more label detail than most broccoli sprout powders give you. One vegan capsule daily, with purity and potency checked by independent labs.
Avmacol is the sulforaphane-producing brand named as the study product in published human trials, and it supplies glucoraphanin together with myrosinase. Tablets can be swallowed whole or crushed.
