Cooking spinach does in fact dull some of its nutritional benefits, folate, vitamin C, niacin, and potassium levels in cooked spinach are all lower than in its pre-cooked form. So if you’re looking to be getting as much of those nutrients as possible it is best to eat spinach raw.

The difference isn’t a massive one though so don’t spend too much time overthinking this: both cooked and uncooked spinach is healthy. Yes, cooking it does damage some nutrients but it also makes other nutrients more bio-available and thus easier to absorb during digestion. Both options are healthy options.
