How to Increase your Body's NAD+ Levels Naturally

How to Increase your Body's NAD+ Levels Naturally

Nicotinamide adenine dinucleotide (NAD+) is an alternative form of the B3 vitamin. B3 is vital for many of the most important biological processes. When your NAD+ levels are low, your risk for chronic diseases of the heart, diabetes, and vision loss increases.

Like your hormones, NAD+ levels begin declining as you get older. To help you maintain steady levels of NAD+ at all times, the staff at Klarity Clinic offers the following guidance.

A better understanding of NAD+

In your younger years, your body has a healthy supply of NAD+, which supports your good overall health and keeps you looking and feeling young and vibrant. NAD+ provides a direct link between your metabolism and the signals in your cells. It also plays a key role in:

  • Repairing damaged DNA
  • Converting food into energy
  • Supporting cell defense systems
  • Coordinating circadian rhythms needed for sleep

As your natural levels of NAD+ begin to decline, your longevity starts to decline, too. For many, this decrease in NAD+ starts when your body can no longer recycle and use the NAD+ you still have. Low levels of NAD+ put you at increased risk for developing chronic disease and makes visible signs of aging more apparent.

By focusing on the natural steps you can do every day to increase your own NAD+ levels, you can boost your overall health and prolong your youthful metabolism and physical energy.

Tips for increasing NAD+ levels naturally

Though there are supplements you can take that increase NAD+ levels, a more efficient way to maintain optimal levels of NAD+ is to make necessary lifestyle changes. Incorporating these changes into your daily life can ensure your NAD+ levels stay strong, so you can maintain a healthy metabolism and high levels of energy.


Exercise is one of the easiest ways to enhance your NAD+ levels and boost your overall health. In addition to keeping you strong and at a healthy weight, regular exercise can increase the DNA-rebuilding proteins in your body.

Daily workouts require more NAD+ for energy, and your body responds by producing it. Staying physically fit can go a long way toward slowing down the progression of the aging process.

Limiting sun exposure

If you spend much time in the sun, you may be prematurely depleting your own supply of NAD+. Direct sunlight on the skin forces your body to use increased amounts of NAD+ to repair cell damage caused by the sun’s ultraviolet (UV) rays.

When you’re outside, limit your time in the sun and cover exposed skin with loose-fitting, lightweight clothing to prevent skin damage.

Seek the heat

Although time in the direct sunlight isn’t good for your overall health or NAD+ levels, spending time in natural or artificial heat can boost those levels.

Heat sources, like hot tubs, saunas, and heated pools, cause your heart to pump faster, requiring more energy from your body to keep cool. This triggers the increased production of NAD+ to supply needed energy.

Dietary changes

Raw foods that contain vitamin B, like avocados, steamed fish, and peanuts, should be part of your daily diet. You can also boost NAD+ levels by drinking two to three glasses of cow’s milk every day.

While you add in these healthy food choices, you should also limit how much bread, rice, and other white flour products you consume. Instead, look for less-processed whole grains that maintain higher amounts of B vitamins.

Another option to consider adding to your diet are fermented foods and drinks, like sauerkraut and kombucha, which contain NAD+. These foods are also good at easing persistent bloating and chronic joint pain.

Fasting and ketosis diets

Intermittent fasting is an eating method that involves periods of eating and cycles of fasting. Popular fasting plans often include 16- to 24-hour fasting periods twice a week, followed by healthy meals. This eating pattern triggers body shock, which can boost your natural supply of NAD+.

Another popular eating plan is a Ketosis diet, which involves following a low-carb, high-protein, healthy fats food plan. This type of diet can help you lose significant weight and enhance your natural levels of NAD+.
