"We do not add chemical excipients."

NPK sticks to 100% nutrients only.

We have developed a technology that does not use chemical excipients and synthetic additives to make health functional foods faster. 

We first introduced the concept of chemical-free excipients, which are now established in the health functional food market.

100% nutrients only

Non-synthetic excipients

“The nutrients I ate to benefit my body contain ingredients that harm my body?!

The Four Free manufacturing method began from this ridiculous reality. 

Nature Pure Korea does not use chemical excipients such as silicon dioxide and magnesium stearate, which were used to make more supplements faster. Chemical excipients are chemical ingredients that have no health benefits and are in fact harmful to health.

Food additives that are not necessary

According to the Food Sanitation Act, food additives are substances used in food for the purpose of sweetening, coloring, bleaching, or preventing oxidation in the process of manufacturing, processing, cooking, or preserving food. (Anti-caking agent, enzyme agent, nutrient fortifying agent, stabilizer, antioxidant, emulsifier, coagulant, etc. depending on use)

1. Silicon Dioxide

2. Magnesium Stearate

3. HPMC(Hydroxypropyl Metal Cellulose) 

4. CMC-CA(Calcium Carboxymethylcellulose) 

5. Synthetic flavoring 

6. Sweeteners

7. Color Additives

These chemical additives and synthetic excipients are said to be safe when consumed in small quantity, but the reality is that they cannot be free from controversy over their harmfulness. So it is highly recommended to carefully check whether health supplements contain synthetic excipients or not before making a purchase.

NPK does not use synthetic excipients just to increase the efficiency of the process!

Silicon Dioxide

Prevents raw materials from hardening or deteriorating by absorbing moisture, and prevents sticking by static electricity generated in machines.

Magnesium Stearate

Acts as a lubricant so that it does not stick to the tableting machine and allows tablets to be produced quickly with a constant weight.


Coats the surface with a smooth coating film to color the tablet, increase the hardness of the tablet, and prevent the product from flying.


Helps accelerate the disintegration rate of poorly soluble ingredients so that they can dissolve well in the body.

Characteristics of Zero Food Additive

😁 Rest assured! 

It is not a product defect. It is a healthy product for the body.
