We track 1 chlorophyll product, but every one is a combination — chlorophyll comes alongside other ingredients and the label's single dose belongs to whichever one the product is built around. We can't say what chlorophyll alone costs per dose in them, so we rank nothing here rather than publish a figure we'd have to invent. See all 1 on the chlorophyll page, or the ranked chlorella they are usually sold with.
We link primary sources and paraphrase their findings — never copy their text, tables, or images. Cost-per-dose figures are our own first-party catalog data.
