Protein Powder Toxicity: Separating Alarm from Reality

In today's episode we're analyzing the panic around Protein Powder Toxicity following a Consumer Reports (CR) study that flagged lead in 70% of products.

We put CR's highly conservative 0.5 mcg/day Prop 65 threshold into context, comparing it to the FDA's safety level of 8.8 mcg/day, which is set 17 times higher and includes a 10x safety margin. 

We explore how lead gets into food and confirm that even the worst-tested powder (7.7 mcg/serving) is within the range of typical daily US exposure (3.2–7.8 mcg/day).

We conclude that while awareness is important, there is no reason to panic, emphasizing that protein powder is a supplement.
