What Foods Are High in NAD+?

Georgina Glenn, Registered Nurse December 12th 2025

What Foods Are High in NAD+?

Looking to boost your levels naturally and wondering what foods are high in NAD+?

NAD+ is gaining more attention in recent years, despite always being a part of our bodies. This is because more studies are showing how important NAD+ is to numerous key processes in the body, including energy production, metabolism, cellular repair, and healthy ageing.

Unfortunately, NAD+ levels naturally begin to decline with age, contributing to elements most associated with ageing such as cognitive decline, muscle loss and signs of ageing on the skin.

The good thing is that there are many foods high in NAD+, but diet alone can’t effectively match the boost from NAD therapy. That doesn’t mean you shouldn’t eat these types of food, so we’re going to look at what foods are rich in NAD precursors, how they work, and how NAD+ at Home can help you.

Understanding How NAD+ Works in the Body

NAD+ stands for nicotinamide adenine dinucleotide. It is a critical coenzyme that exists within every cell in the body and is vital for nearly endless key processes to help us function.

NAD+ has many benefits, but most importantly, it is involved in energy production and is a key component of ATP (adenosine triphosphate), the main energy source for all cells in the body. It is also a key part of DNA repair, helping metabolism and promoting healthy ageing.

No matter what you do, NAD+ levels in your body will decline as you age. Your body becomes less efficient at synthesising it, meaning levels drop, and NAD+ has much more to combat as your body gets older.

Other factors such as stress, alcohol, inactivity and illness can also contribute to reduced NAD+ levels. These factors increase oxidative stress in the body, cause inflammation and disrupt mitochondrial function. All this depletes your NAD+ levels and leaves these important molecules to fight on too many fronts.

NAD+ Precursors

NAD+ is not created in a vacuum. It needs to come from something, and that is NAD precursors. These are the building blocks of NAD and can be found in foods that increase NAD levels.

Important NAD precursor nutrients to be aware of are:

  • > Tryptophan
    > Niacin (B3)
    > Nicotinamide Mononucleotide (NMN)
    > Nicotinamide riboside (NR)

What Foods are High in NAD+?

If you are looking to make positive changes and lead a healthier and more active lifestyle, here are some NAD+ diet tips that could help.

Foods Rich in Tryptophan

    Tryptophan is an amino acid and a key building block for the creation of NAD+ via the kynurenine pathway in the liver.

    Foods rich in tryptophan include:

    • > Turkey
    • > Chicken
    • > Salmon
    • > Eggs
    • > Beef
    • > Tofu
    • > Dairy

    Niacin-rich foods (vitamin B3)

    Niacin is a vitamin and a vital precursor that the body can convert into NAD+, and it can be useful in managing cholesterol levels and improving mitochondrial function.

    Foods rich in niacin include:

    • > Beef liver
    • > Chicken breast
    • > Tuna
    • > Peanuts
    • > Mushrooms
    • > Sweet potatoes
    • > Green peas

    Dairy sources of NR

    There are not many natural sources of NR, which is another form of vitamin B3. The most well-known sources of NR are full-fat cheeses and milk, especially cow’s milk.

    Other foods, such as bread and oranges, contain NR, but only a small trace amount that would be unlikely to make a difference to your NAD+ levels.

    Whole Grains and Legumes

    Whole grains and legumes, such as brown rice, lentils, and beans contain significant amounts of niacin and other forms of vitamin B3, supporting NAD+ metabolism.

    Vegetables High in Antioxidants

    Antioxidants are compounds that combat oxidative stress in the body. They work with NAD+, so foods high in antioxidants are helpful for cellular repair and help reduce NAD+ depletion as they take on some of the workload.

    Vegetables are high in antioxidants, so you should concentrate on eating:

    > Cauliflower

    > Broccoli

    > Avocado

    > Leafy greens (spinach, kale)

    > Red cabbage

    Fermented foods

    Fermented foods can support gut health, which, in turn, indirectly supports NAD pathways, helping with processes related to inflammation and metabolism and easing the burden on NAD+ levels.

    Fermented foods to try:

    > Miso

    > Sauerkraut

    > Kimchi

    > Kefir

    Can Diet Alone Boost NAD+ Enough?

    There are many forms of natural NAD sources, with a healthy diet being the easiest way to support your NAD+ levels. However, diet alone will not boost your NAD+ levels to a significant degree.

    This is because food doesn’t contain NAD+; it contains the precursors that we explored above. In the body, these precursors are turned into NAD+, and then you start to get the benefit of this key coenzyme.

    The problem is that your NAD+ levels will naturally decline, no matter what. Age, stress and a busy lifestyle will deplete your NAD+ levels and the amount of NAD that food provides you with is not enough to overcome what is lost.

    That is why eating well and exercising are great platforms for boosting your health and NAD+ levels, but if you want to see real change, then supplements, NAD pens, and NAD+ injections offer more substantial boosts. Combining these three strands into a health routine will allow you to get the benefits of boosted NAD+ levels and leave you feeling healthier and maximise your body’s potential.

    How NAD+ At Home Products Support Optimal NAD+ Levels

    Whilst food supports baseline health and can contribute to rising NAD levels, NAD therapy delivers clinically meaningful increases that help you reap the benefits you are after.

    In terms of NAD+ treatments, many push forward with IV therapy treatment. Whilst this can be an effective method of boosting NAD+ levels, it is expensive and a much more involved process than many people have time to deal with.

    At NAD+ at Home, we offer a range of ways for you to boost your NAD+ levels in your own home.

    NAD+ Injection Kit

    We offer NAD+ injection kits that are a convenient and efficient way to increase your NAD levels. Our solution is pure NAD+ in its active form, and we provide all the equipment you need to perform the subcutaneous injection, bypassing bodily processes that would break down the NAD+.

    NAD+ Pens

    If you are not a fan of needles, we have home injection pen kits, making the process even quicker and more convenient. This method is nearly 100% bioavailable, meaning you rapidly absorb the NAD+ solution with hardly any of it being wasted, giving you the maximum benefits.

    NAD Supplements

    Beyond injections, our NAD+ liposomal capsules are easy to take orally, and you can quickly incorporate them into your daily routine. Liposomal means that the supplement is enclosed within lipid bubbles that increase absorption and effectiveness.

    Ready to Make NAD Supplements a Part of Your Health Routine?

    Eating a well-balanced, healthy range of foods should be the cornerstone of your life, helping you optimise your health. However, diet alone can’t make a big dent in dropping NAD+ levels, but combining NAD boosting foods with supplements can help you gain the health benefits you are after.
