- high-fat, low-carb keto diet. Being in ketosis, the state where your body uses fat instead of glucose for energy, increases the NAD+ to NADH ratio. You want higher NAD+, because it protects cells from oxidative stress[20][21] — an imbalance between free radicals and antioxidants in your body that contributes to aging.[22][23]
- Practice intermittent fasting. Restricting your eating increases NAD+ levels.[24][25] Though calorie-restriction diets and periods of fasting will do it, those aren’t sustainable for the long term. Intermittent fasting is, if you do it right. Here’s how to get started with intermittent fasting.
- Take oxaloacetate. A higher ratio of NAD+ to NADH helps you make more energy and makes your cells work better. Oxaloacetate activates the longevity pathway in a similar way that calorie restriction does. It converts to malate, which raises your NAD+ to NADH ratio,[26] which makes more NAD+ available for your cells to use. Try: KetoPrime, a highly bioavailable form of oxaloacetate.
