What is Leonardite?
DOUBLE BLACK is formulated with the best source of Leonardite found in Gascoyne, North Dakota. Leonardite is a mined mineraloid that formed as deposits of ancient plant material aged and oxidized over time (essentially a young coal). Low in contaminants and high in organic content, North Dakota Leonardite contains significantly more humic and fulvic acids than other sources.
