What is Vitamin D3?

Vitamin D3 (cholecalciferol) is a unique vitamin, synthesized in our skin through exposure to sunlight. Its role in the body is fundamental. However, many people do not get enough sun exposure, especially those living in low-light regions or spending most of their time indoors. In such cases, supplementation becomes a valuable ally.

 

Prevalence of Vitamin D3 Deficiency

A study carried out in Portugal showed that 66% of Portuguese adults were deficient in Vitamin D3. 19
Studies in the European population show that there is an epidemic of Vitamin D3 deficiency, with 401% of Europeans having Vitamin D3 levels that are considered insufficient 20. These values are more prevalent in winter, due to the absence of sunlight.

 

Optimal Levels and Deficiency of Vitamin D3

Deficiency is considered when levels are below 29 ng/mL (75nmol/L). 21
Adequate levels range from 32ng/mL to 100ng/mL (80nmol/L-250nmol/L). 22

 

Why Combine Vitamin D3 with Vitamin K2?

Vitamin D3 increases the absorption of calcium in the intestines, this in high amounts can cause hypercalcemia 23 24 25, which is excess calcium in the bloodstream, especially when combined with calcium intake, this process can lead to arterial calcification 26.
Vitamin K2, being a strong inhibitor of arterial calcification, prevents this process from occurring. It also directs excess calcium to the bones. 27 28
Vitamin K2 has been shown to reduce markers of calcification in controlled studies. 29 30

Importance of the Form of Vitamin K2

Not all forms of Vitamin K2 are equally bioavailable, so you need to be careful when reading the label to know exactly which form of K2 is present.
Vitamin K2 MK4 is much inferior and has no effect on Vitamin K2 levels when compared to the MK7 form, which is what we use in our product. 31

 

Problems Associated with Vitamin D3 Deficiency

The list of problems associated with Vitamin D3 deficiency is vast, levels should always be monitored to ensure adequate levels.
A deficiency in this vitamin increases the risk of bone fractures. 32, chronic kidney disease 33, diabetes 34, multiple sclerosis 35, mortality 36, rickets 37, osteoporosis 38, depression 39 and much more.

 

Is the Vitamin D3 dosage in this product safe?

The EFSA (European Food Safety Authority) has determined 4,000 IU as the acceptable limit, even for children over 11 years old. 40
Doses below 10,000 IU per day pose a very low risk of developing Vitamin D3 toxicity. 41

Take 1 capsule per day, together with a meal. Preferably in the morning or early afternoon.
