If you buy the powder its red, if you buy the capsules it's grey. I don't understand why the difference, but my purchase of the pill has shown some odd effects. Part of the benefits of this product is Inflammation Management per this company’s website. I have RA and a couple days after starting on the capsules, my inflammation and pain has become much worse. I have been taking for almost a month now, and I am considering dumping the rest of this garbage down the toilet. There is no logical reason why the powder and contents of a pill should be any different. Just because there is a label on something doesn't mean that is actually what is inside. Maybe it's time to have it independently tested.
