25 Hydroxyvitamin D3 (25-OH-D3) (Water Soluble, Mixing Type)


25 hydroxyvitamin D3 is a metabolite of vitamin D3 hydroxylated by the liver.
It is the main active form of vitamin D3 in human and animal blood circulation and an indicator of the nutritional status of vitamin D3 in the body.

Product Parameters:
Name: 25 hydroxyvitamin D3(25-OH-D3), is also known as 25 hydroxycholecalciferol. It is important nutrient for healthy bones.
CAS RN: 63283-36-3
25-Hydroxyvitamin D3 monohydrate molecular formula: C27H44O2•H2O
FW: 418.7

Type: water soluble and mixing type for option
Storage: well-ventilated and dry
Shelf life: 12 months
Test Method: HPLC


The biological potency is 3 ~ 5 times of vitamin D3, which can be transformed into the final active metabolite more effectively; 1234
No liver conversion is required, which shortens the metabolic process of vitamin D3 and makes it absorbed more quickly;
Not impacted by intestinal malabsorption, liver damage or liver dysfunction;
The absorption mode is different from that of fat-soluble vitamins (A, D3, E, K3) and does not depend on bile secretion and the formation of fat-absorbing micro-aggregates.

Application of 25-OH-D3 in poultry:


Prevention of paralytic chicken, reduce the death of chicken;
The growth period: promote the skeleton development;
High-yield period: reduce osteoporosis and cage layer fatigue, to extend the laying cycle;
In the later period of laying eggs: the quality of eggshell is improved, the strength of eggshell is increased, the deformed egg, the thin eggshell and the broken eggshell are reduced, and the body weight of chicken is eliminated.


Improve growth performance, enhance bone development, promote intestinal development and improve immunity;
Increase the rate of brisket, reduce the rate of bone damage in the process.

Breeding birds:

Reduce the number of dead embryos, increase the hatchability, increase the qualified rate of breeding eggs, reduce the number of broken eggs, white shell and thin shell eggs;
Raise the egg production rate, maintain the egg production peak;
To obtain the maximum bone volume before sexual maturity and reduce the early mortality rate.

Application of 25-OH-D3 in swine:


Improve skeletal development, reduce foot and limb disease,improve gilt selection rates,extend the service life;

Improve the pregnancy rate, improve the reproductive performance of sows (live litter size, newborn and weaning
weight, survival rate of piglets, survival rate and healthy rate of piglets, increase litter weight) and milk composition;

Improve the retained placenta, to solve the problem of postpartum paralysis.


Improve calcium and phosphorus absorption and utilization, improve skeleton development, reduce the incidence of rickets and osteoarthropathy, improve growth performance, enhance antibody level, enhance disease resistance.


Increase sperm motility, semen volume and sperm count; increase fertilization rate.

Fattening Pig:

Before slaughter to improve meat color, improve the department of hydraulic.
