Can I get a recommendation for a good vitamin?

Since I worked outside a little during the summer, I felt like my stamina was quite low.

I'm exercising and making a lot of effort, but I still feel lacking... A good multivitamin.

I'm thinking of buying one and eating it to try to manage my stamina a little.

I was originally taking a product from Chong Kun Dang, but I heard other brands are also okay. I would appreciate your recommendation.
