ADEK, 200 tablets – fat-soluble vitamins A, D, E and K, OstroVit

Product Overview

OstroVit ADEK tablets combine four fat-soluble vitamins in one formula: vitamin A, vitamin D, vitamin E and vitamin K. People usually choose this type of supplement when they want one product that covers several basic nutritional needs at once rather than taking separate capsules. It is especially relevant when the focus is on vision, bone maintenance, immune function and antioxidant protection.

How the Vitamins Work

The value of this combination lies in how these nutrients work in different but connected ways:

• Vitamin A helps maintain normal vision and is involved in cell specialization, which is important for tissues that renew themselves quickly.
• Vitamin D helps the body absorb calcium and phosphorus, making it central for bones, teeth and muscle function.
• Vitamin K contributes to proper blood clotting and also works alongside vitamin D in bone metabolism.
• Vitamin E acts as an antioxidant: it helps protect cells from oxidative stress, a process linked to free radicals formed during training, sun exposure, pollution and other external influences.

Vitamin Forms Used

The forms used here are standard and well known in supplements:

• Retinyl acetate for vitamin A
• Cholecalciferol for vitamin D
• DL-alpha-tocopheryl acetate for vitamin E
• Menaquinone-7 (MK-7) for vitamin K, a form of vitamin K2 valued for its good persistence in the body compared with shorter-acting forms

Because ADEK vitamins are fat-soluble, they are generally taken with food containing some fat, which fits how these nutrients are absorbed.

When to Consider This Supplement

This OstroVit vitamin complex may suit adults who want a simple long-course option for:

• Seasonal use
• Periods of low sun exposure
• A varied training schedule
• A more limited menu

It can also be practical for those who prefer tablets over several separate products.

Important Notes

A sensible note: this formula includes a relatively high amount of vitamin D and also contains vitamin K, so it is worth checking whether it matches your current supplement plan. If you are pregnant or breastfeeding, use blood-thinning medication, or are monitoring your vitamin D status, speak with a healthcare professional before use.
