Protein supplements are enough if you want to make gains and stay healthy at the same time. Protein, pre-workout and meal replacement supplements are great but they won’t support your recovery the way health supplements would. You should be taking health supplements like vitamins, joint support, etc. even if you don’t workout.
As you age, your body becomes inefficient at producing health supporting enzymes. It is a great idea to supplement your diet with health supplements as you age. It is even more important for people who workout or have an active lifestyle which includes physical activity all day long.
