It is so challenging to find spices without all the contamination or California Proposition 65 warning. Even many popular organic spice brands do carry the CA Prop 65 warning for detected lead or other heavy metals. The challenge is finding a supplier that sources their spices in lead-contaminated lands; many plants are naturally more prone to gather heavy metals from the ground! Same for coffee and chocolate; many brands sell them anyway without bothering to search for better suppliers other go above and beyond to avoid t his risk.
I admire these kinds of brands that take extra steps to ensure their products are safer and healthier, and that are the brands I want to support! Like these ones listed on this page!
❌ Avoid conventional cinnamon full of pesticides, glyphosate, and packed in plastic packing
Consuming too much cinnamon, particularly the common Cassia variety, carries several health risks due to its compounds and potential contaminants. “Conventional cinnamon” likely refers to conventional (non-organic) cinnamon, which has been linked to issues like lead contamination in some products.
The two main types of cinnamon are:
Cassia cinnamon is more commonly found in supermarkets, given that it’s much cheaper than Ceylon cinnamon.
According to the FDA: Certain conventional cinnamon brands have tested positive for elevated lead levels, posing risks like developmental issues in children and long-term blood lead accumulation from regular use.
Consumer Reports found high lead levels in a third of the cinnamon powders and spice mixtures we tested. Here are the ones that pose the most and least risk.
❌ Avoid greenwashing cinnamon made by brands that pretends to be organic, safer, or healthier, when they are not. They will use their misleading marketing tricks to convince you to but their products.
Glyphosate (Roundup’s active ingredient) has been detected in some cinnamon samples, including organic ones, potentially from post-harvest drying sprays or environmental drift, at levels up to 50 parts per million in isolated tests.
One brand tested over 1,200 parts per billion of lead, which means a single gram could exceed the daily warning limit by 140%.

Both Simply Organic Cinnamon versions have the warning!
