This grade is built from the label data we could match for this product, so parts of it — like the full nutrition panel — may not appear here yet. A grade is only as sharp as the label we can actually read, and it gets better every time someone shares a clear photo of the real product. Rescan the ingredients and nutrition facts and we'll sharpen it.
