Product Range and Specialties of Changsha Vigorous-Tech Co., Ltd.

The catalogue offers a green tea L‑theanine ingredient, which in the industry is typically supplied at a purity of 98 % - 99 % and marketed for its amino‑acid content. Instant green tea powder is usually standardized to a certain percentage of polyphenols (e.g., 30 % - 40 % catechins) and sold in fine‑particle form for beverage blends. The 100 % natural taro powder is a root‑derived vegetable powder, commonly limited to a moisture content below 8 % and a particle size distribution of 150 - 500 µm for optimal solubility. Fisetin powder, a flavonoid used in nutraceuticals, is generally offered at ≥95 % purity with low residual solvent levels. Reishi mushroom extract is typically a hot‑water or alcohol extract with a beta‑glucan content of 10 % - 20 % and may be supplied as a dried powder or granulate. These specifications reflect the grades and parameters buyers commonly request for each product type.
