Use the first question to define the right starting page, then confirm the matching specification and sample in the target formula.
| Ingredient | Best starting question | Review first |
|---|---|---|
| Urolithin A | Does the project need a defined active ingredient powder? | Identity, assay or purity target, COA, residual solvents and sample lot. |
| L-Theanine Green Tea Extract | Does the project need a tea-derived L-Theanine specification? | 20% / 40% target, HPLC, COA, solubility and taste. |
| Green Tea Extract | Does the project need a broader tea extract marker profile? | Catechins, tea polyphenols, EGCG, caffeine and assay method. |
| Instant Green Tea Powder | Does the project prioritize tea flavor, color and beverage solubility? | Solubility, color, taste, sediment and application fit. |

HERBSEA supplies bulk Urolithin A powder, L-Theanine green tea extract and Green Tea Extract, together with broader botanical extracts, instant tea powders, fruit powders, mushroom extracts and functional ingredients. Product pages should be reviewed for the applicable specification and application details.
Start with the ingredient identity, product form, target assay or marker, finished-product application, destination market, estimated quantity, packaging preference and required documents. Then request the matching specification, representative or batch COA and sample plan.
No. Urolithin A is a defined active ingredient entity, while pomegranate extract is a botanical extract. Buyers should compare identity, assay method, specification, COA and sample fit separately rather than treating them as interchangeable products.
L-Theanine green tea extract is reviewed around a stated L-Theanine assay and HPLC method, while instant green tea powder is generally reviewed around beverage application, solubility, color and tea sensory fit. Confirm the exact grade and documents for the intended formula.
First identify the marker or application requirement. Green Tea Extract may be compared by catechins, tea polyphenols, EGCG, caffeine or another agreed marker; EGCG is a more specific catechin target; L-Theanine is reviewed by its own assay and HPLC specification. Compare like-for-like methods and COA fields.
Yes. Send the target ingredient, specification or assay target, application, sample quantity, estimated bulk volume, destination market and document requirements through the contact or RFQ path. Confirm the sample lot, COA, specification, packaging, MOQ and lead time with HERBSEA before approval.
