GreenPacks Green Tea Extract
A green tea leaf extract standardised to 50% EGCG at $9.99, non-GMO and vegetarian, sold on antioxidant and metabolic support rather than on weight loss claims. Publishing the standardisation is the right disclosure for this ingredient. What the page does not mention is the reason concentrated green tea extract needs care: it is among the more common supplement causes of drug-induced liver injury.

What’s in it
Amounts are shown only where the manufacturer publishes them. Anything without a figure is undisclosed — and for an active ingredient, an undisclosed dose is the central problem with this category.
- Green tea leaf extract (Camellia sinensis)Standardised to 50% EGCG
EGCG is the most abundant catechin in green tea; the per-serving milligram amount was not published on the page we captured
How the manufacturer says it works
GreenPacks describes it as a potent extract standardised to 50% EGCG supporting cellular health as a super antioxidant, stating that green tea's polyphenols and catechins assist in the destruction of free radicals and support metabolism, and that EGCG supports proper cell cycle regulation and helps maintain healthy tissues.
What the evidence actually supports
Publishing the standardisation percentage is the correct disclosure for a botanical extract, and 50% EGCG is a meaningful specification rather than a vague 'green tea extract'. Green tea catechins have a genuine research base for antioxidant activity, and there is some evidence for a small effect on energy expenditure. The claims made here stay on antioxidant and cellular support rather than promising weight loss, which is the defensible framing for this ingredient.
Where that evidence stops
The per-serving milligram amount is not published, so the standardisation percentage alone does not tell you the EGCG dose — and dose is exactly where the safety question sits. Concentrated green tea extract is one of the more frequently implicated supplement ingredients in drug-induced liver injury, with case reports and regulatory reviews in several countries, and risk appears to rise with higher doses taken on an empty stomach. The page carries no liver caution at all. Green tea's effect on body weight is small and inconsistent in trials, and drinking green tea is not equivalent to a concentrated extract. None of this is a GLP-1 mechanism.

May suit
Someone who wants a cheap standardised green tea extract for antioxidant reasons, takes it with food, and has no liver concerns.
Do not use if
- You have any liver condition, or take medication that affects the liver
- You would take it on an empty stomach, which appears to raise the risk
- You already take multiple products containing green tea extract — the doses add up
- You are pregnant or breastfeeding
Frequently asked
Is green tea extract safe?
Drinking green tea is; concentrated extracts warrant more care. Green tea extract is among the more commonly implicated supplement ingredients in drug-induced liver injury, and several regulators have reviewed it. The risk is not large in absolute terms but it is real, appears dose-related, and seems higher when taken on an empty stomach. Take it with food, do not stack multiple products containing it, and avoid it entirely if you have any liver condition.
What does 50% EGCG mean without a milligram figure?
Only half the information. It tells you the extract is concentrated — half its weight is the active catechin — but not how much extract is in a capsule. A 250 mg capsule at 50% gives 125 mg of EGCG; a 500 mg capsule gives 250 mg. Since the safety question is dose-dependent, that missing number matters more here than in most products. Check the physical label.
