STORY AT-A-GLANCE Glyphosate limits plant absorption of micronutrients like manganese after application and may lead to a reduction of manganese in the food supply Crops that are normally high in manganese, such as soybeans, leafy vegetables, coffee, tea and whole grains, are commonly sprayed with glyphosate for weed control Your body requires a balanced amount of manganese since too much can have neurotoxic effects and insufficiency may result in neuropathologies, such as Alzheimer’s disease, Parkinson’s and depression Insufficiency may also affect bone health and reproductive function. The answer to reducing your risk is to eat certified organic foods whenever possible Manganese is an essential trace element you must get from your food as your body cannot make it.

Manganese is used as a cofactor for many enzymatic
