Which vitamins/supplements do you take?

That's not entirely true. Many fish (tuna, salmon, mackerel, flatfish/halibut, swordfish, herring, sardines, anchovies, trout, eel, catfish, cisco, sturgeon, rockfish, tilapia), oysters, mushrooms (wild or commercial UV treated), liver (cod, beef, lamb, pork, chicken), egg yolks, margarine are high in Vitamin D. A serving of certain wild mushrooms (shiitake) contain multiple times the amount of vitamin D a person needs a day. There's an enhancement hack too: place the mushrooms under direct sunlight or UV lamp for a few hours, they will contain a lot more Vitamin D.

An adult needs around 600 IU of vitamin D per day. Here's a few examples with the vitamin D content of rather common food:
100g canned red/sockeye salmon: 730 IU
100g smoked chinook salmon: 600 IU
100g cooked swordfish: 600 IU
100g cooked rainbow trout: 660 IU
100g canned tuna: 270 IU
100g cod liver oil: 10,000 IU, 1 tsp: 450 IU
1 cup of chanterelle, portobello, shiitake, morel: 400 IU
1 hard-boiled egg: 30 IU
250ml fortified milk: 100 IU
Fish, mushrooms, organ meat, eggs are very much part of a healthy diet. As you can see, it's far from being impossible to have your needed vitamin D intake just from food, in fact you can easily have multiple times of that and you weren't even outside on the sun yet, let alone the need to take supplements.

In the US they add vitamin D to cow's milk, soy milk, dairy products, cereals, oatmeal, orange juice by default.

It can depend on the line of work, the activities you do and your diet, whether you need vitamin D supplement or no. If you sit in front of a computer most of the time, you don't go out much and you don't eat any of the above food, which is rich in vitamin D, supplementing is definitely something to consider.

A good portion of the vitamin/supplement industry is just a marketing scam on the same level as the bottled water industry.
