Introduction
Vitamin D3 is one of the most important vitamins in the human body. Although often referred to as a vitamin, it actually functions similarly to a hormone and influences many bodily processes – from immune system function to bone health and muscle function.
In Latvia, where the number of sunny days in autumn and winter is limited, vitamin D3 deficiency is common. Therefore, many people choose to take vitamin D3 supplements year-round or seasonally.
If you are looking for vitamin D3 in Jūrmala or want to know how to choose a quality product, this guide will help you make an informed decision.
What is Vitamin D3?
Vitamin D3, or cholecalciferol, is a form that the body synthesizes in the skin under the influence of the sun's ultraviolet radiation.
It can also be obtained through diet or supplements.
Vitamin D3 participates in:
- calcium absorption processes;
- bone mineralization;
- muscle function;
- normal immune system function;
- cell division processes.
Why is Vitamin D3 important?
According to health claims approved by the European Food Safety Authority (EFSA), Vitamin D:
- contributes to the normal function of the immune system;
- helps maintain normal bones;
- helps maintain normal muscle function;
- helps maintain normal teeth;
- contributes to the normal absorption of calcium and phosphorus;
- helps maintain normal blood calcium levels.
Signs of Vitamin D3 Deficiency
Vitamin D3 deficiency can manifest in various ways. Common signs include:
- persistent fatigue;
- frequent illnesses;
- muscle weakness;
- bone pain;
- reduced physical performance;
- slower recovery after exertion.
If you suspect a vitamin D deficiency, it is advisable to consult a doctor and undergo a 25(OH)D blood test.
Vitamin D3 or D2 – what's the difference?
| Vitamin D2 | Vitamin D3 |
|---|---|
| Ergocalciferol | Cholecalciferol |
| Plant origin | Animal origin or lanolin |
| Lower bioavailability | Higher bioavailability |
| Less commonly used | Most commonly recommended in supplements |
Many studies show that vitamin D3 is more effective at raising and maintaining blood vitamin D levels than vitamin D2.

Vitamin D3 with K2 – is it better?
Vitamin D3 is often combined with vitamin K2.
This combination is popular because:
- D3 helps absorb calcium;
- K2 helps deliver calcium to bones and teeth.
If enough calcium is consumed through the diet, the D3 and K2 combination can be a good choice. However, vitamin D3 alone is also effective in helping to maintain normal vitamin D levels in the body.
Vitamin D3 for athletes
Vitamin D3 is especially important for athletes because it helps maintain:
- normal muscle function;
- bone health;
- immune system function during periods of intense training.
This is relevant for strength athletes, runners, cyclists, and anyone who regularly engages in physical activity.
When to take Vitamin D3?
Vitamin D3 is a fat-soluble vitamin, so it is recommended to take it with a meal containing healthy fats.
Many choose to take it:
- at breakfast;
- at lunch;
- at the same time every day.
The most important thing is regular use.
What dose to choose?
The necessary dose is individual and depends on age, lifestyle, diet, and vitamin D levels in the blood.
The most appropriate dose should be chosen in consultation with a healthcare professional and, if necessary, based on test results.
Vitamin D3 in winter in Latvia
In Latvia, from autumn to spring, the sun's UVB radiation is often insufficient for the skin to synthesize the necessary amount of vitamin D3.
Therefore, during this period, many choose to take supplements to maintain optimal vitamin D levels.
