During the summer months, the body can use sunlight quite effectively. However, from autumn to spring, the sun is too low in our latitudes, and the natural synthesis in the skin drops to almost zero. During this long period, a high-quality dietary supplement is an absolute necessity for maintaining health, strong bones, and a robust immune system.
It is absolutely the most effective and safest combination. Vitamin D helps the body absorb calcium from food, but it is Vitamin K2 that acts as a "GPS," directing this calcium straight into the bones and teeth. This prevents its dangerous buildup in the blood vessels (calcification).
Vitamin D acts more like a hormone in the body, and its impact on athletic performance is massive. In addition to supporting immunity and bone strength, it has a direct effect on proper muscle function and maintaining optimal testosterone levels, which is absolutely crucial for building muscle mass, strength, and overall vitality.
Because Vitamin D is fat-soluble, you must always take it together with a meal that contains some fat (e.g., in the morning after a breakfast with eggs or after lunch). If you swallow it on an empty stomach with just water, your body won't be able to absorb it properly, and a large part of it will be wastefully excreted.
Yes, it is possible. Since it is fat-soluble, the body stores it in its reserves and cannot simply excrete the excess in urine like Vitamin C. Therefore, it is important to follow the recommended dosage on the packaging (usually 1000 to 4000 IU daily depending on the season and your workload) and not unnecessarily swallow extra handfuls of capsules.
