New Supplement Powder Fixes a Hidden Flaw in Sulforaphane Capsules
Tempe, Arizona – September 11, 2026 -- Nootropics Depot has launched SulfoMax, a powdered sulforaphane supplement designed to fix a chemistry problem the company says undermines standard capsule versions of the compound.
Sulforaphane, a compound studied for its role in cellular defense and cognitive resilience, is too unstable to bottle directly. Most supplements instead combine glucoraphanin, a stable precursor, with the enzyme myrosinase inside a capsule, relying on the two to react after swallowing.
Lab testing found stomach acid disables the key enzyme
Nootropics Depot's analytical lab ran that reaction through a Distek dissolution tester using simulated gastric fluid. At stomach-acid pH, myrosinase was largely inactivated, meaning much of the precursor in a conventional capsule can pass through the body without converting into active sulforaphane.
