MCSubstradd Mushroom Supplements


Legro Australia can offer MCSubstradd delayed-release nutritional mushroom supplement for professional mushroom growers.


MCSubstradd® is a new name for an old and proven product.

Since 2008, MCSubstradd® regroups 2 existing brands for mushroom-supplements: MilliChamp® and Substradd®.

MilliChamp® started in the 1970’s, based on a patent for production and use of delayed-release proteins.
Since it’s start, MilliChamp® has been a reference in the mushroom-industry, famous for its quality, advanced research and innovation. Substradd® was developped by Mr. Wim Joosten, another pioneer and field expert in mushroom supplementation.

In 2008 both brands have joined forces in MCSubstradd®, the new brand-name.
MCSubstradd® is produced in a separate part of the large HAVENS-site on the Meuse-river in the south of the Netherlands, where it has been manufactured since the early 1990’s in a 100% dedicated production line, from reception of the ingredients right up to filling of the bags or bulktrucks.

Thus, MCSubstradd® combines cost-effectiveness to optimal product-quality.
