What's your diet like? Are you eating a variety of leafy green vegetables? If not, add that to your daily food intake. You don't even really need to change anything else if you don't want to. But eating a variety of dark leafy greens will help your mitochondria, the powerhouse of your cells. Foods that help your gut are also imports, so sauerkraut, kimchi, yogurt etc. fermented foods.

I add them to pretty much any of my foods, even when I am eating junk. Kimchi on pizza is one of my favorite combinations. It's really good. I'll cut up arugula and add it to my nachos. I add dark leafy greens to all my burritos, whatever else.

With any new diet change, start small and slow. So, if you barely eat dark leafy greens, start with spinach and add a bit of kale or arugula every couple of days. Same with yogurts and kimchi's and stuff. Eat small amounts to begin with. Your body needs to adjust to the new foods. Eating too much too soon can cause discomfort.

I'm 37 I feel much better than I did in my 20's but I have completely transformed my diet from mainstream processed foods to vegetable laden, especially dark leafy greens. I also do stretching exercises 1-3 times a week. Keeps me limber, and its relaxing, vs working out which is tiring. ( I work out too, but it's the stretching that makes me feel better!)
