    Fresh broccoli and broccoli sprouts are two of the healthiest foods available due to their high concentrations of a category of compounds called glucosinolates. The two most beneficial compounds are glucoraphanin and sulforaphane which have become the focus of longevity scientists in recent years with over 650 studies exploring the health benefits.

    Sulforaphane is an active compound found in many cruciferous vegetables like broccoli, cabbage, cauliflower, and kale. 

    The amount of Sulforaphane in food is minuscule, for example, you would need to eat about more than a kilogram of broccoli to get significant amounts of sulforaphane. Sulforaphane is also a fragile compound which means that typical cooking and preparation can destroy a majority of the beneficial nutrients.

    The challenge of accessing the beneficial compounds is further complicated due to Sulforaphane being found in its inactive form within food. This inactive form - glucoraphanin  - is activated into Sulforaphane only when it comes into contact with Myrosinase. These critical Myrosinase enzymes are only released when a plant is damaged, cut, chopped, or chewed, to release myrosinase and convert inactive Myrosinase into activated Sulforaphane.

    Recent studies show that adding myrosinase derived from ground raw mustard seeds to cooked crucifers increases the bioavailability of sulforaphane by up to 4 times. This activation of glucoraphanin into sulforaphane is the focus for our Active Sulforaphane powder which is a proprietary blend of Sulforaphane, Myrosinase and black pepper.

    Independent laboratory testing is critical to ensure that the product is at least 99% pure and contains no dangerous levels of heavy metals or micro-organisms. If an online retailer is not providing test results then there is no certainty that there products is pure or even the product that they claim it to be and whether it’s safe for human consumption. Establishing purity and authenticity is critical when consuming small molecule longevity supplements like NMN. It is clear that the market has many websites selling impure or fake NMN.
