Most of the health benefits are the same across the caffeinated and decaf versions, with only a minor magnification of effects in some areas due to the ‘entourage effect’. So you’re still onto a winner with the decaf. The areas where decaf isn't as protective are broadly: Liver health. Coffee is very protective of the liver. Those effects are more pronounced in regular coffee. Cognitive health. Especially age-related cognitive benefits are slightly less pronounced in decaf. I wouldn’t worry though, if you’re not a fan of caffeine (or it's not a fan of you!), the decaf is still packed full of antioxidants and polyphenols so is hugely beneficial.
