Testing by the Health Research Institute found 92 unknown compounds in Bored Cow's synthetic milk — produced from a "form of genetic engineering" — in addition to significant nutrient deficiencies. Over a dozen companies use similar formulations in products like cream cheese, smoothies and ice cream.

Recent testing revealed 92 unknown molecules — and a fungicide — in "synthetic" milk now sold in common grocery chains, according to the Health Research Institute (HRI).

The product, sold by Bored Cow, uses a fake whey protein called "ProFerm" made by biotech company and partner Perfect Day. Perfect Day uses genetically modified "microflora" to produce the synthetic milk protein.
