Not bandwagoning here but I agree with you, I could care less about my cap being white if clear is healthier. Same with food coloring. While taste does matter, I dont care if the color of the drink or powder is bright and appealing also. Especially if it is achieved through some unhealthy chemical or dye. Though we might be a minority when it comes to the common consumer used to gatorades and sour patch kids.
If I recall Steves argument for TD is that the amount in a capsule pales in comparison to food and toothpaste, and the study that claimed it toxic was for inhalation not consumption.
Either way, I take a lot of pills so I'd like to lean towards minimizing potential toxins in the long run. I already do that with my toothpaste, foods, fabrics and products when possible - but my supps and peds I hope benefit more than degrade my health.
