Health Canada has recalled three lots of Miracle Reds superfood powder.
It is advising people who have immunocompromising conditions such as AIDS or lymphoma to stop taking the product.
The recall comes as the products in those lots are missing labels with information about the risks of taking the powder.
MacroLife Naturals markets Miracle Reds as a source of 19 fruits and berries containing probiotics, antioxidants and enzymes.
