1.Что такое Экстракт листьев шелковицы? Traditional Use and Modern Research
Mulberry leaf has been used in Chinese medicine for centuries – mostly for “clearing heat, moisturizing the lungs, and improving eyesight.” But the reason modern formulators are interested in it is its potential for blood sugar management.
Mulberry leaves are what silkworms eat. Silkworms grow fat and healthy on them. Humans won‘t turn into silkworms, but research shows mulberry leaf does affect how your body absorbs sugar. A decade or two ago, Japan and Korea already started making functional foods from mulberry leaf – teas, biscuits, noodles. More recently, Europe and North America have begun paying attention, especially as “natural blood sugar support” becomes more popular.
One thing worth noting: mulberry leaf is gentle. It doesn’t hit you like some prescription diabetes drugs. It‘s not a medicine and can’t replace medical treatment, but as part of a daily diet, it can help smooth out post-meal blood sugar spikes.

2.Основные активные соединения и их действие
Mulberry leaf contains several types of active compounds. Two are most studied:
DNJ (1-deoxynojirimycin)
The name is a mouthful. Just think of it as a “natural alpha-glucosidase inhibitor.” Alpha-glucosidase is an enzyme that breaks down carbohydrates. DNJ slows it down, so some sugars aren’t absorbed. That lowers the blood sugar peak after a meal. Several mainstream diabetes drugs (like acarbose) work the same way. But DNJ is natural and tends to have fewer side effects.
Flavonoids and polyphenols
Things like quercetin, kaempferol, and chlorogenic acid. These are antioxidants with anti-inflammatory effects. They can also improve insulin sensitivity. Good for long-term metabolic health.
Most research shows the effect of mulberry leaf extract is gentle but steady. You won‘t see a dramatic drop after one meal. But with consistent use, the daily blood sugar swings get smaller.
Честно говоря: there isn’t as much human clinical data on mulberry leaf extract as on some mainstream ingredients. But East Asian countries have accumulated lots of real-world use and some studies. Japan‘s Ministry of Health even approves mulberry leaf tea as a “Food for Specified Health Uses” (FOSHU) for blood sugar improvement.
3.Масса Экстракт листьев шелковицы Поставщиков: На что обратить внимание
Quality varies. Here’s what you should check:
Содержание DNJ – This is the key functional marker. Usually ranges from 0.5% до 2%. Higher costs more.
Соотношение экстрактов / Чистота – Common ratios are 10:1 или 20:1 (20 kg of raw leaf to make 1 kg of extract). Ratio alone doesn‘t matter as much as DNJ content.
Pesticide residues – Mulberry trees can get pests. If raw material isn’t well managed, residues can exceed limits.
Растворимость – Are you making a drink mix (needs to dissolve) or capsules (doesn‘t matter)? That affects which spec you need.

We supply mulberry leaf extract standardized by DNJ content (например., 1%, 2%) or by extract ratio. Our raw material comes from contracted farms with good agriculture practices. Every batch is tested for pesticides, тяжелые металлы, и микроорганизмы.
Типичные применения
| Тип продукта | Рекомендуемая дозировка | Примечания |
| Капсулы/таблетки для поддержки уровня сахара в крови | 100–300 mg extract (containing 1–4 mg DNJ) | Often blended with cinnamon, хром, bitter melon |
| Functional drink sticks | 100–200 mg per stick | Often uses maltodextrin carrier for better flow and taste |
| Healthy snacks | Варьируется | Mulberry leaf biscuits, noodles – already common in Japan/Korea |
| Meal replacement powders | 50– 150 мг | As a supporting ingredient for metabolic health |
| RTD blood sugar beverages | 50–100 мг | Watch solubility and taste (mulberry leaf has a grassy note) |
4.OEM & Оптовые услуги, которые мы предлагаем
We don’t just sell raw material – we also do contract manufacturing. If you want to launch a “post-meal sugar support” drink stick or capsule, мы можем помочь с разработкой формулы, смешивания, наполнением, и упаковкой.
Распространённые синергетические смеси:
Mulberry leaf + Cinnamon extract + Chromium – classic natural blood sugar stack.
Mulberry leaf + White kidney bean extract – white bean inhibits amylase (starch breakdown), mulberry inhibits alpha-glucosidase (disaccharide breakdown). They complement each other.
Шелковица + Bitter melon + Fenugreek – broader metabolic support formula.
Шелковица + Pueraria root extract – a traditional Chinese medicine pair for “blood sugar and heat relief.”
Что мы предоставляем:
DNJ content tested by HPLC for every batch.
Third-party pesticide, heavy metal, and microbial reports.
Fair pricing – not the cheapest, but you get what you pay for.
Регуляторная поддержка – документы на пищевой ингредиент, экспортные документы.
5. Тенденции рынка: Who’s Using It?
Mulberry leaf extract is most established in Asia (Япония, Korea, Китай). Europe and North America are catching up.
Япония – The earliest adopter. You see mulberry leaf tea, порошка, and supplements in many drugstores, marketed for blood sugar support.
Korea – Common in functional foods and health drinks.
Китай – Fast growth in the last three years, especially in meal replacements, light meals, and functional drink sticks.
Северная Америка / Европа – Mostly in dietary supplements for glucose metabolism, often blended with cinnamon, хром, берберин.
Because mulberry leaf has traditional use and some clinical data, consumer acceptance is decent – especially among people familiar with herbal supplements.

7.Часто задаваемые вопросы
1 квартал: Does mulberry leaf extract actually lower blood sugar?
It helps reduce post-meal blood sugar spikes. It‘s not like insulin that directly lowers glucose. If you eat a high-carb meal and take mulberry leaf extract at the same time, the rise in blood sugar will be smoother. But it’s not a drug and cannot replace medical treatment.
2 квартал: What‘s the right daily dose?
Depends on DNJ content. Most people take 1–5 mg of DNJ per day. Например, if your extract has 1% DNJ, then 100–300 mg of extract per day is typical.
3 квартал: Any side effects?
Большинство людей не испытывают никаких. At higher doses, some people feel mild digestive discomfort (bloating, gas). That happens because some carbs aren’t absorbed and reach the large intestine, where bacteria ferment them. It‘s the same side effect as alpha-glucosidase inhibitor drugs. Usually reducing the dose fixes it.
4 квартал: Can pregnant or breastfeeding women use it?
Lack of safety data. Better to consult a doctor or avoid.
Квартал 5: How is it different from white kidney bean extract?
White kidney bean inhibits amylase – it mainly stops starch from breaking down. Mulberry leaf inhibits alpha-glucosidase – it stops disaccharides from breaking down into single sugars. Similar but different targets. Many people blend them for broader coverage.
В6: Do you offer organic mulberry leaf extract?
Да. Sourced from certified organic farms. MOQ and pricing available on request.
