Practical answers
What is Hesperetin standardized to, and how is it measured?
Hesperetin: 98% (HPLC). The marker set is Hesperetin, citrus flavonoids. The primary method is HPLC; the batch COA reports the result against the agreed specification. Other ratios, marker ranges, carriers, and mesh sizes can be quoted as a custom grade after a feasibility review.
Which source and plant part are used for Hesperetin?
Citrus aurantium; Fruit. The source and part are stated on the specification and the COA because they are release parameters, not marketing descriptions. If the label names a different part, confirm it before the first order.

Metabolic capsules, Liver wellness formulas, Daily wellness, Tablets. The grade is selected against the finished format, dose, and destination market; a sample and application brief are more useful than a generic catalogue comparison.
Which documents are supplied with the batch?
A batch-specific COA, technical data sheet, SDS, allergen and GMO statements, and an origin record. Third-party heavy-metal, pesticide, or microbiological reports can be arranged, as can Halal, Kosher, or organic certificates where the grade is covered.
What is the minimum order, lead time, and sample size?
1 kg minimum, packed in a 1 kg foil pouch; bulk drums are available as quantities scale. 1–7 days after specification and order confirmation. Samples are typically 100–500 g with their own COA, usually within 3–5 business days after the specification is agreed.
