If you don’t exercise and don’t physically strain, a lifestyle with an emphasis on mental work, there is a load on vision, then you don’t need to take a complex complex, you can focus on vitamins of group B like Berrocca's pop https://filzor.ru/catalog/ berokka_plyus_tab_ship_kh30 /, the effervescent formula gives faster utilization, and the effect to improve overall well-being will be followed, I noticed by my feelings that I started to sleep better and by the evening my eyes stopped getting tired, if the physical load is strong then the complex is more saturated and more lethal from the sports nutrition, for example, but keep in mind that dosages there are much higher than those of pharmacies.
It is best that it contains Vitamins A, D, C, K, B6 and B12. So it would be nice that the complex would contain not only vitamins but also other substances (Zinc, Magnesium, etc.) Everything is individual. Choose which ones you need. But make sure that it contains at least basic vitamins. And not just a couple of vitamins and a bunch of other unimportant substances.
I recommend taking a quality American brand multivitamin. Vitamins should be in coenzyme bioavailable forms, minerals in chelated forms. Read my detailed article on how to choose a multivitamin - https://natural4.ru/multivitaminy-iherb-kakie-luchshie/
All kinds of vitamins should be taken only on the recommendation of a doctor based on tests.
If the tests do not show a lack of vitamins or there is no trend towards decreasing, then you just need to diversify your diet. There are more generalities and fruits.
Adjusting your diet, eating more fruits and vegetables is the best way.
optima nutrition has good vitamins (but the dosages are large there)
If from a pharmacy, then the brand "Alphabet" to help
