Cas number: 67-97-0

Molecular formula: C27H44O

Molecular weight: 384.64 g/mol

HS Code: 2936290090

Vitamin D3, also known as Cholecalciferol, is a white powder soluble in lipids or fat but insoluble in water.

It can withstand high temperatures and oxidation in neutral and alkaline solutions.

According to one experiment, when its solution is heated at 130 degrees for 90 minutes, its physiological activity remains undamaged, but it gradually decomposes under acidic conditions.

It is the most widely used nutritional supplement for bone growth issues.

It is administered by mouth as soft gels or gummies. In serious conditions, people will have to take VD3 injections to treat certain diseases.

It works by promoting the absorption and deposition of calcium and phosphorus in the intestine.

How Much Does Vitamin D3 Cost?

About the costs of Vitamin D3, please note that there are at least three types of VD3 in the market:




Different grades have different prices, which is obvious.

But how do you tell the differences between each grade?

Say if I have 3 bags of white powders on the table without any labels of course, are you able to tell which is what?

If you can not, here is the trick: choose the fine crystals with the whitest color, it is pharma-grade.

Food grade and feed grade have white and off-white or even light yellow colors.

The color difference is caused by the impurity control during the manufacturing process.

Pharm-grade has high-quality standards, activity is required to be over 40Million IU/G, and the market price is around 5000USD per kilo.

When we say pharm-grade, it means this API is GMP-certified.

Or even if it is 98% purity meeting USP, it is still food-grade.

Food-Grade: 1Million IU/G, the price idea is around 60~100USD/kg.

Feed-Grade: 100,000IU/G~500,000IU/G, price is around 15~30USD/kg.

We mainly stock 98% type VD3 powder, with or without GMP, the unit price for 1kg is about 5000usd per kg.

How To Ship and Store Vitamin D3 Powder?

As we mentioned above, VD3 powder is very stable. You can ship it by air or by the sea at room temperature. 

Stability testing has shown that it is stable for 3 years at room temperature.

But for long-term storage, it is suggested to be stored at 2~8 degrees celsius.

The tricky part is the shipping though.

Vitamin D3 oil is often used as an acute mice poison, which means vitamin D3 of oil form is very poisonous.

It is also proved that pharm-grade Vd3 powder is also poisonous, and you may want to label and handle it properly. 

While the food-grade and feed-grade vd3 powder is tested to be very safe and non-poisonous.

They are suitable for shipping as a common chemical.
