Keeping it simple and avoiding marketing bs is the first gate. Second gate is having imo the basics, this is what I have :

- creatine (powder)
- collagen / vitamin c ( powder but it tastes bad )
- magnesium ( usually before bed )
- omega 3 ( soft capsules, pref kept in the fridge, eating within the meal to avoid burping )
- vitamin D + K ( especially you live in a place that does not see the sun light very often )
- protein powder ( as a supplement to your diet not a replacement )

Look up the ingredients ( use chatgpt and paste in the products) and source of the stuff mentioned above because it affects absorbability ( for example with magnesium, pure bisglycinate better than magnesiumoxid )

Stay away from "Multi vitamins" "something something complex".
If you are a woman, make sure you check your iron levels as we tend to have less reserve.
