1.是什么 桑叶提取物? 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.主要活性成分及其作用原理
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.
To be honest: 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.散装 桑叶提取物 供应商: 选择要点
Quality varies. Here’s what you should check:
DNJ 含量 – This is the key functional marker. Usually ranges from 0.5% 到 2%. Higher costs more.
Extract ratio / 纯度 – Common ratios are 10:1 或 20:1 (20 kg of raw leaf to make 1 kg of extract). Ratio alone doesn‘t matter as much as DNJ content.
杀虫剂残留 – Mulberry trees can get pests. If raw material isn’t well managed, residues can exceed limits.
溶解性 – 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 (例如, 1%, 2%) or by extract ratio. Our raw material comes from contracted farms with good agriculture practices. Every batch is tested for pesticides, 重金属, 以及微生物.
Typical applications
| 产品类型 | Recommended Dosage | 备注 |
| Blood sugar support capsules/tablets | 100–300 mg extract (containing 1–4 mg DNJ) | Often blended with cinnamon, 铬, bitter melon |
| Functional drink sticks | 100– 每根棒含 200 毫克 | 通常使用麦芽糊精作为载体以改善流动性和口感 |
| 健康零食 | 不同 | 桑叶饼干, 面条 – 在日本/韩国已经很常见 |

桑叶 + Bitter melon + Fenugreek – broader metabolic support formula.
桑叶 + Pueraria root extract – a traditional Chinese medicine pair for “blood sugar and heat relief.”
我们的提供:
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.
法规支持——食品配料文件, 出口文件.
5. 市场趋势: Who’s Using It?
Mulberry leaf extract is most established in Asia (日本, Korea, 中国). Europe and North America are catching up.
日本 – The earliest adopter. You see mulberry leaf tea, powder, and supplements in many drugstores, marketed for blood sugar support.
Korea – Common in functional foods and health drinks.
中国 – Fast growth in the last three years, especially in meal replacements, light meals, and functional drink sticks.
北美 / 欧洲 – 主要用于调节血糖的膳食补充剂, 通常与肉桂混合, 铬, 小檗碱.
因为桑叶具有传统使用历史并且有一些临床数据, 消费者接受度不错 – 尤其是对草本补充剂熟悉的人群.

7.常见问题解答
问 1: 桑叶提取物真的能降低血糖吗?
它有助于减少餐后血糖高峰. 它不像胰岛素那样直接降低血糖. 如果你摄入富含碳水化合物的食物并同时服用桑叶提取物, 血糖升高会更平缓. 但它不是药物,不能替代医疗治疗.
问 2: 适合的每日剂量是多少?
取决于 DNJ 含量. Most people take 1–5 mg of DNJ per day. 例如, if your extract has 1% DNJ, then 100–300 mg of extract per day is typical.
问 3: Any side effects?
Most people have none. 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.
问 4: Can pregnant or breastfeeding women use it?
Lack of safety data. Better to consult a doctor or avoid.
问 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.
问 6: Do you offer organic mulberry leaf extract?
是的. Sourced from certified organic farms. MOQ and pricing available on request.
