Key Takeaways:

      • NAD isn’t directly found in foods. However, foods containing NAD precursors can help our bodies generate NAD.
      • Animal-based foods like beef liver, chicken, turkey breast, and salmon contain the NAD precursor niacin.
      • NMN-rich foods like tomatoes, edamame, and broccoli help support NAD production.
      • Plant-based foods like legumes and grains contain less niacin per serving.
      • Foods containing tryptophan, such as turkey, chicken, and milk, can also help with NAD generation.

    It’s no wonder researchers and health enthusiasts have been looking for natural ways to increase the body’s NAD (nicotinamide adenine dinucleotide) levels. After all, NAD plays a crucial role in numerous processes.

    Beyond boosting energy, NAD may be beneficial in helping to promote healthy aging, improve cognitive function, and protect against heart disease.

    It turns out the key to unlocking higher NAD levels might already be hiding in our daily meals. Keep reading to learn more about the food sources that can boost your NAD levels.

    NAD+ and NADH are two versions of the same molecule. NAD+ is the oxidized form, while NADH is the reduced form. Throughout this article, we’ll refer to it as NAD.


    Is NAD Found in Foods?

    No, NAD the molecule is not found directly in foods, but NAD precursors are found naturally in foods.

    The cells in our bodies need certain building blocks, known as NAD precursors, to generate NAD. After they enter our bodies, these precursors undergo chemical changes in the cell to form NAD.

    These precursors include nicotinamide mononucleotide (NMN) and tryptophan. Niacin, also called vitamin B3, is a well-known NAD precursor. Niacin comes in different forms like nicotinic acid (NA), nicotinamide (NAM), and nicotinamide riboside (NR).


    What Foods Contain NAD Precursors?

        • The list provided is not exhaustive, and there are other foods that contain NAD precursors.
        • The amount of NAD precursors in foods can vary depending on the cooking method and other factors.
        • The values mentioned in the table are general estimates and may vary in specific food items.

      The table below lists foods that contain NAD precursors.

In addition to being an excellent source of niacin, beef liver is also rich in iron, vitamin B12, and zinc. In a 3-ounce serving of pan-browned ground beef that is 90% lean, there are 5.8 mg of niacin. Raw beef contains a small amount of NMN, ranging from 0.06 to 0.42 mg per 100 grams.
          • Turkey: A serving of turkey breast weighing 3 ounces offers 10 mg of niacin and 244 mg of tryptophan. Alongside its niacin content, turkey breast is an excellent source of protein, vitamin B6, vitamin B12, and zinc.
          • Fish: Sockeye salmon (about 3 ounces cooked) or tuna (canned in water, drained, about 3 ounces) provide 8.6 mg of niacin. Additionally, fish is known for its omega-3 fatty acids content, which helps promote heart health.
          • Rice: Both brown and white rice are staple foods that provide important nutrients to our diet. A 1-cup serving of cooked brown rice contains 5.2 mg of niacin, while the same amount of cooked white rice provides 2.3 mg of niacin. In addition to niacin, brown rice is rich in essential vitamins and minerals and is mainly known for its higher fiber content compared to white rice.
          • Tomatoes: They are a tasty and nutritious addition to meals. Half a cup of cherry tomatoes provides approximately 0.5 mg of niacin. Tomatoes also contain NMN in amounts ranging from 0.26 mg to 1.60 mg per 100 grams. Moreover, tomatoes are a good source of antioxidants, vitamin C, and riboflavin.

Milk also contains protein, calcium, zinc, and riboflavin and is beneficial for bone health and preventing osteoporosis in adults.


        Is Eating Foods High in NAD Enough to Replenish NAD?

        Eating foods high in NAD precursors can support the body’s natural production of NAD, but it might not be sufficient to replenish NAD levels fully.

        The effectiveness of NAD production from these precursors can vary based on individual factors such as age, genetics, and overall health. Additionally, our bodies’ ability to convert these precursors into NAD may differ from person to person.

        To maximize the benefits of NAD, adopt a holistic approach to health. In addition to incorporating NAD-rich foods into your diet, maintaining a balanced and varied eating plan can provide a wide range of nutrients that support overall well-being. Regular physical activity and adequate sleep also play vital roles in supporting NAD production.


        Why Is NAD Good For You?

        NAD is good for you because it plays a vital role in various processes within our cells.

        One of its primary functions is to help convert food into energy. This energy is essential for our daily activities, from simple tasks like walking to more complex functions like thinking and breathing.

        NAD also serves as a critical component in DNA repair, helping to fix damaged DNA and maintain the integrity of our genetic information.

        The levels of NAD in our bodies tend to decrease as we age. can lead to reduced energy production and increased vulnerability to age-related health problems. Maintaining adequate NAD levels may support healthy aging, boost cognitive function, and protect against certain heart diseases.


        NAD vs. NMN: What’s the difference?

        NAD is a molecule in the body that plays a role in energy production, DNA repair, and anti-aging. NMN is a NAD precursor – a building block that the body uses to create NAD – found in various foods and supplements.

        Are NAD supplements worth it?

        NAD levels decline with aging, and supplementation can help boost levels. However, it’s a good idea to talk with your healthcare provider to determine if NAD supplements are appropriate for you and to ensure safe and effective use. 

        What happens when NAD converts to NADH?

        When NAD converts to NADH, it gains an electron, becoming the reduced form of the molecule. This conversion is crucial for many chemical reactions in our cells that produce and use energy.

        Which NAD supplement is best?

        The best NAD supplement may vary depending on individual needs and health goals. NAD supplements are available in many forms, such as capsules, tablets, or intravenous therapy. These supplements generally contain precursors that the body can use to produce NAD. Some supplements offer direct forms of NAD. 

        Can NAD help you lose weight?

        NAD may indirectly support weight loss by promoting optimal metabolic function and energy production, but it should not be considered a weight loss supplement. A healthy lifestyle that includes a balanced diet and regular exercise remains essential for successful weight management.

        Final Thoughts

        To maximize NAD’s benefits, consider adding foods rich in NAD precursors to your meals daily. A balanced diet with a mix of these precursors can keep your NAD levels optimal. Also, living a healthy lifestyle, with exercise and good sleep, helps your body produce more NAD.
