How we research and check our pages

Every guide on Pure Green Tea follows the same rules, written down so you can judge our pages for yourself. Accuracy comes first: a shorter page that is right beats a longer page that guesses.

Where our facts come from

Every factual claim on a page, such as a caffeine figure, a health effect or an ingredient, comes from a source listed at the bottom of that page. We only cite pages we opened and read, never a search snippet. We look for sources in this order:

1. Government and health agencies, such as NCCIH, NIH, the FDA, EFSA and USDA FoodData Central.
2. Peer-reviewed research, usually found through PubMed or PubMed Central.
3. Major medical institutions, such as Mayo Clinic or Harvard's Nutrition Source.
4. A brand's own site or label, but only for facts about its own products.

We avoid content farms and AI-generated pages. Tea sellers are only used for brewing habits or facts about their own teas. If a source blocks us, we don't work around it with proxies or cached copies. We use another strong source or leave the claim out.

What we won't do

• Invent numbers. If a brand doesn't publish its caffeine, sugar or EGCG, we say so instead of estimating it as fact.
• Present our own math as a measurement. When we scale a figure, for example from a 12 oz serving to a whole can, we label it as our math.
• Make up tasting notes, lab tests, personal stories, experts or statistics.
• Call a product "best" without evidence, or imply we tested something we didn't.
• Copy or closely paraphrase other sites, including the old blog that used this domain.

Health topics

• We only say a food or drink "may" help when a source supports it, and we say plainly when the evidence is weak or comes only from lab or animal studies.
• We never claim that tea treats, cures or prevents a disease.
• We keep extracts and supplements separate from brewed tea, because most green tea studies don't apply to a cup, let alone a flavored bottled drink.
• Pages about health, safety, allergies, pregnancy or medication carry a reminder to check with a doctor or pharmacist.

We aren't doctors or dietitians, and nothing here is medical advice. See our disclaimer.

How we use AI tools

Articles are drafted with AI tools. Each draft is then checked against the sources listed on the page, and claims we can't confirm are removed or labeled as uncertain. We would rather tell you "we couldn't find this" than fill the gap.

Reviews and corrections

Every page shows the date it was last reviewed. Labels and research change, so we recheck pages and update the date when we do. When two of our pages end up answering the same question, we combine them into one fuller page and redirect the old address.

Money and independence

The site shows ads, which pay for running it. It doesn't currently use affiliate links. Brands don't pay us to cover them, and nothing we earn changes what a page says. Brand names belong to their owners, and Pure Green Tea isn't affiliated with any brand we mention.
