What is the price of white mulberry leaf extract in bulk wholesale?

White Mulberry leaf Extract has quietly become one of the most requested botanical ingredients in the dietary supplement and functional food industries. Its reputation rests on a single remarkable compound, 1-deoxynojirimycin (DNJ), a natural alpha-glucosidase inhibitor that helps slow the breakdown of carbohydrates and supports healthy postprandial blood sugar levels. For supplement brands, food manufacturers, and private-label companies, the question is rarely whether to use it. The real question is what it costs when you buy it in bulk.

What is white Mulberry leaf Extract?

White Mulberry leaf Extract is produced from the leaves of Morus alba L., a tree that has been cultivated in Asia for centuries for both its fruit and its leaves. The extract is standardized mainly on its DNJ content, which is the compound responsible for most of its health benefits. Alongside DNJ, the leaves are rich in polyphenols such as Quercetin, kaempferol, and chlorogenic acid, which add antioxidant value to the ingredient.

Because of this profile, white mulberry leaf extract is widely used in blood sugar support formulas, weight management products, functional teas and beverages, and general wellness supplements. It is typically supplied as a fine powder that can be encapsulated, tableted, or blended into powdered drinks.

What determines the bulk price?

There is no single fixed price for bulk white Mulberry leaf Extract, because the ingredient is sold to specification. The price you pay depends mainly on the following factors:

• DNJ concentration. This is the single biggest price driver. Standardized extracts are commonly offered at 1%, 1.5%, 2%, 5%, and 10% DNJ. A 1% DNJ product is far more affordable than a 10% DNJ product, because producing a higher concentration requires more raw material and a more demanding purification process.
• Raw material quality. Leaves sourced from GAP-certified organic planting bases cost more than conventionally grown material, but they deliver cleaner, more consistent extracts and make organic claims possible.
• Production technology. Low-temperature extraction, chromatographic separation, and spray drying preserve active compounds and improve purity, but they also add to production cost. Suppliers that invest in this equipment charge accordingly.
• Order quantity. As with most wholesale ingredients, the unit price drops as the order volume rises. A 25 kg order will always cost more per kilogram than a 500 kg order.
• Certifications and documentation. Extracts backed by ISO9001, USFDA, TGA, or organic certification, and supplied with a full certificate of analysis, command a premium because they reduce your compliance risk.
• Packaging and logistics. Food-grade packaging, sealed drums, and international shipping all factor into the final delivered price.

What price range can you expect?

Public marketplace listings give a rough sense of the spread. Low-concentration Mulberry leaf Extract at 1% DNJ is commonly listed in the tens of dollars per kilogram range, while highly standardized extracts at 5% to 10% DNJ are priced substantially higher per kilogram. Between those extremes, the price scales steadily with DNJ content, batch size, and the supplier's quality credentials.

It is worth keeping in mind that listed prices are only a starting point. Raw material harvests, exchange rates, and market demand all cause prices to move over time. The only reliable way to know what you will actually pay is to request a direct quote for your exact specification, so the numbers you see on a listing page should never be treated as a firm price.

Why buying from a source factory keeps costs down

The most effective way to lower your unit cost is to buy directly from a source factory rather than through a trading intermediary. A manufacturer that grows or sources its own raw material, runs its own extraction lines, and controls its own quality testing can offer factory-direct pricing that traders simply cannot match.

Plant Extract Wholesale, the English wholesale arm of Hangzhou Green Sky Biotechnology, is exactly this kind of source factory. The company has more than 20 years of experience in plant extract production, operates a 5,000-mu GAP-certified organic planting base covering more than 200 kinds of herbs, and maintains three advanced factories equipped with extraction, concentration, distillation, separation, and spray drying lines. With an annual plant yield extraction of 500 tons and a catalog of more than 200 products, it produces at a scale that keeps per-kilogram pricing competitive while holding quality to cGMP and GLP standards. Certifications including ISO9001, USFDA, TGA, MEDSAFE, and SGS GMP management system certification give buyers confidence in every batch.

For buyers who need more than a standard product, a source factory also offers flexibility. Custom DNJ concentrations, custom particle sizes, private-label packaging, and value-added documentation such as certificates of origin and commodity inspection reports can all be arranged directly with the manufacturer.

How to get an accurate bulk quote

To get a meaningful price from any plant extract supplier, prepare the following details before you reach out:

• Target DNJ concentration. State whether you need 1%, 2%, 5%, or 10% DNJ. This single detail has the largest effect on price.
• Quantity. Give your expected annual or per-order volume, so the supplier can quote the best tier price.
• Application. Mention whether the extract will go into capsules, tablets, beverages, or another format, because this can influence particle size and processing requirements.
• Required documentation. Ask for a certificate of analysis, heavy metal and microbial test reports, and any organic or GMP certificates you need for your market.
• Samples. Always request a sample batch before committing to a large order, so you can verify color, taste, solubility, and assay results against your specification.

If you are ready to buy plant extracts in bulk, sending a clear specification is the fastest route to a competitive price. A reputable manufacturer will respond with a detailed quote, a certificate of analysis, and often a free sample, so you can compare apples to apples across suppliers.

Final thoughts

The bulk price of white Mulberry leaf Extract is not a fixed number; it is a function of DNJ concentration, raw material quality, production standards, order volume, and documentation. The good news is that the ingredient is produced at scale by experienced manufacturers, which keeps it accessible for brands of every size.

The smartest approach is simple: define your specification, request samples and certificates, and compare quotes from source factories. Do that, and you will get a fair bulk price for a high-quality ingredient that your customers can trust.
