**Sulforaphane** at 400 mcg per capsule — sourced from a 20:1 broccoli sprout concentrate. Sulforaphane activates your body's Nrf2 pathway, which ramps up your natural antioxidant defenses and supports cellular detoxification. Multiple clinical trials show promise for cardiometabolic health and oxidative stress reduction, though the evidence is still maturing.

The dose here is the key consideration. Examine's estimated effective range is 1,000–9,000 mcg (1–9 mg) per day, which means you're getting about 40% of the minimum studied dose in one capsule. To reach the low end of the effective range, you'd need to take 2–3 capsules daily instead of the suggested one.

At the label dose of one capsule, you're likely below the threshold where clinical benefits have been observed. If you're serious about sulforaphane for antioxidant or cardiometabolic support, plan on a higher daily intake — and factor the cost of going through the bottle faster.
