Why buy Green Tea Extract (25:1) 500mg?
Concentration

As we’ve seen, green tea leaves naturally contain a range of polyphenols.
What if we concentrate the plant’s leaves? Well, we get more polyphenols!
That’s exactly what we did with our green tea extract: we concentrated the plant’s leaves by 2,500% so you can enjoy large amounts of green tea through easy-to-take capsules.
Standardized extract. A quality guarantee
Extract concentration matters; higher concentration usually means more chemical constituents, but that’s not always the case, since certain product treatments can seriously affect extract quality.
That’s why standardizing active content is a practice that guarantees supplement quality.
Our Green Tea Extract (25:1) 500mg contains per serving:
- 475 mg of polyphenols (95% of its content).
- 350 mg of catechins (70% of its content).
- 225 mg of EGCG (45% of its content).
- 10 mg of caffeine (2% of its content).
At HSN, transparency is always our priority. You can check with maximum precision what we offer in every single product and why our raw materials are top quality.
Vegan
Green tea is a plant, so its extract is a completely plant-based product suitable for vegetarian and vegan diets.
However, many competitors ruin capsule products by using gelatin as coating agents. These capsules become unsuitable for vegans.
In our capsule products, we use a vegetable cellulose derivative to make veggie capsules, 100% suitable for vegetarians and vegans.
