Top 6 NAD-Boosting Foods: An NAD IV Therapy Toronto Info Sheet


Our functional medicine clinic offers NAD IV therapy in Toronto to help tackle various health concerns, such as brain fog, degenerative diseases, cellular metabolism, and more. Did you also know that certain foods contain NAD? Eating these may help sustain coenzyme levels in your body. 

Nicotinamide adenine dinucleotide (NAD) is crucial for the human body’s cellular health and functioning. It’s an essential coenzyme that can be produced in the body – however, as the body ages, the amounts of NAD diminish. 

Because this coenzyme is vital for the function of enzymes, NAD deficiencies can make the body susceptible to:

    • Age-related conditions (i.e. age-related weight gain)
    • DNA damage
    • Poor cardiovascular health
    • Weak muscle function
    • Oxidative stress
    • Chronic fatigue
    • Mitochondrial dysfunction
    • Memory loss

When a regular NAD IV drip is combined with healthy lifestyle modifications and other wellness interventions (i.e. medical advice, naturopathic medicine healing) it can contribute to health advantages. Consuming foods with NAD can also help support optimal NAD levels – the Toronto Functional Medicine Centre (TFMC) lists these foods below for educational purposes.

NAD-rich foods to consume

NAD precursors can help sustain or reinforce NAD in the human body. An article from Oxidative Medicine and Cellular Longevity confirms that “… the amino acid tryptophan or forms of vitamin B3 (niacin, nicotinic acid, niacinamide) as well as nicotinamide riboside (NR), nicotinamide mononucleotide (NMN), and nicotinic acid riboside (NaR) stimulates the formation of NAD+.” 

These constituents can be consumed via oral supplements, or you can try adding these NAD-ladened foods to your diet:

    • Cow’s milk: Dairy milk contains tryptophan, nicotinamide, as well as NR. Further research is necessary, but The Journal of Nutrition emphasizes that milk has the capability to “…bind and preserve the integrity of NR [which] makes dairy products potentially good sources of supplemented NR.”
    • Turkey: This meat contains both tryptophan vitamin B3, which are both NAD precursors. According to the National Institutes of Health (NIH), you can consume 180mg of tryptophan and 3mg of niacin from one cooked turkey breast (3oz). 
    • Various fruits and vegetables: In 2016, it was discovered that NMN can be consumed from tomatoes, avocados, broccoli, cucumbers, and edamame. Among those foods, edamame and avocado were shown to contain notable amounts of NMN. 
    • Beef: Eating cooked beef on a moderate basis can also help sustain your NAD because it carries niacin. We recommend buying grass-fed beef because it also has nourishing antioxidants and omega-3s. Beef manufactured using conventional practices are known to have excessive fat content with low amounts of niacin.  
    • Fish: Anchovies, salmon, and tuna are known to contain B3. As reported by WebMD, “Sockeye salmon and canned tuna both offer 8.3 mg of the nutrient. Canned anchovies, which are also an excellent source of selenium, contain just 1mg of niacin per fish.” Keep in mind that eating tuna once a week should be practiced to avoid mercury exposures. 
    • Whole grains: Both whole and enriched grains carry NAD precursors. In particular, brown rice encompasses niacin and other amounts of nutrients, such as manganese, thiamin, selenium, vitamin B6 and magnesium. Opting for brown rice is ideal because it tends to contain various nutrients, as it’s not as processed as white rice.  

Nutritional needs vary between individuals – after all, each person has different health concerns, health goals, genetics, nutritional deficiencies, environmental exposures, lifestyles, and various amounts of physical exertion/athletic performance. Even food sensitivities and allergies can play roles in individual health needs! To ensure that new dietary measures suit your goals and condition, integrative care practitioners can offer personalized assistance. Our functional medicine clinic is accepting new patients for functional medicine, IV vitamin therapy, and NAD therapy treatments (i.e. oral supplements and intravenous therapy).
