Multi-Purpose Antioxidant

NAC is an amazing powerhouse antioxidant and so much more! As a valuable partner of your immune system, NAC is most notably used for its ability to breakdown excessive mucous but it also reduces oxidative stress (free radicals) and its effects from pollution, stress, and excessive exercise. It helps liver detox processes and is used in cases of acetaminophen overdoses.

    Anti-Aging Marvel

    As an antioxidant, N-Acetyl Cysteine, a derivative of the amino acid cysteine, stimulates the production of glutathione, another potent antioxidant and one of your liver’s main detoxifying compounds. By squelching free radicals NAC helps slow aging and reduce inflammation, which can increase your risk of chronic disease. This scavenger helps protect cell walls from damage, which in turn supports our immune system so it does not have to deal with mutated cells so that immune resources can be focused where better needed.

    Enerex NAC 1000 uses pharmaceutical grade ingredients and offers the highest potency product on the market.

    Get the NAC of it.  NAC, which stands for N-Acetyl Cysteine, has been researched for a variety of benefits for over 20 years. NAC works as a team player behind the scenes to increase natural chemicals in the body that are vital to keep you young and healthy; and it also helps other nutrients to be more effective.

    It is used in many hospitals for its anti-inflammatory and mucous-reducing effects. NAC counteracts toxic chemical poisoning and negative reactions caused by drugs. It has also been used to combat mental illness.

    How valuable are antioxidants?

    You couldn’t survive without them. How necessary it is for you to supplement with them to “fight free radicals”? That depends on:

    • how balanced your diet is (you get antioxidants from certain foods),
    • how compromised your immune system is (illness creates greater need),
    • how active you are (exercise increases free radicals),
    • how old you are (antioxidants are anti-aging), and
    • how healthy you strive to be (antioxidants prevent disease).


    One tough free radical fighter! Enerex NAC 1000 offers 1000 milligrams of the natural, research-supported antioxidant the highest potency available. This N-Acetyl Cysteine supplement brings out the big guns to fight radical molecules that can increase aging and disease. NAC is said to have antioxidant benefits because it makes the body produce more Glutathione. Glutathione is a powerful free-radical reducer, sometimes called “the body's master antioxidant.”

    What is Glutathione?

    Glutathione can be found in every cell of the human body.  Glutathione is made from three amino acids – cysteine (associated with NAC), glycine and glutamate. The highest amount of glutathione is in the liver, where it is vital to the body's detox processes.

    Glutathione is an essential part of the body's natural defense system. Viruses, bacteria, pollution, heavy metals, radiation, everyday chemicals, medications, and even the process of aging all cause free-radical damage to cells — and these deplete Glutathione. A lower level of glutathione has been connected to low immune function because of the body’s reduced ability to detoxify the harmful free radicals.

    What does this have to do with NAC? It is because NAC is closely associated with the antioxidant Glutathione that, as a supplement, it:     

    • May treat bronchitis and ear infections
    • Has been shown to lower risks of heart disease and lower cholesterol
    • Increases immunity against certain flus
    • May help increase energy, and enable the body to recover faster after injury
    • Has been studied for benefits in reducing side effects from medications including NSAIDs and other pain medication particularly acetaminophen, and reducing cancer treatment side effects
    • Helps psychiatric conditions including bipolar disorder, schizophrenia, Alzheimer’s and depression
    • May help with symptoms of Lou Gehrig’s disease
    • Might reduce addictions to cocaine and cigarettes 

    Trusted by doctors 

    Hospitals use N-Acetyl Cysteine to aid patients with heavy mucous in their lungs, such as those with Cystic Fibrosis and pneumonia. It is also used by doctors to reduce throat/air passage problems developed after surgery in tracheotomy patients. In addition to N-Acetyl Cysteine’s antioxidant effects, some of NACs benefits are due to the fact that it is a part of the amino acid cysteine, and this helps the body build protein.

    There is much research behind NAC’s benefits: as an antioxidant, to make drugs less harmful, for Schizophrenia, addictions and Bipolar Disorder, to increase heart health and to help reduce symptoms of Cystic Fibrosis.

    "I discovered Enerex back in 2013. Before my training to become a Certified Holistic Nutritionist, I was working for a tiny health food shop in Bloor West, Toronto. 

    With my passion for knowledge and wellness, I found pleasure in analyzing and researching the plethora of supplement products available. Before I was classically trained at the Institute of Holistic Nutrition I was driven to Enerex’s brilliantly crafted formulas. I started utilizing the Original Greens Formula, NAC 1000, and Memoria in my own routine, and I spoke highly of them to my family and friends.

    Fast forward 6-years later. I still feel joy and get excited over this collection of essentials, builders and functionals. Enerex has played a role in my own wellness since the beginning of my journey, and it remains a total go-to for my nutritional practice - to help people thrive and be vibrant. 

    They're nutritional brilliance, truly."

    I’m a Holistic Nutritionist + Wellness Specialist. In a nutshell, I’m a foodie, I love healthy, easy-to-prepare meals with fresh ingredients. But I want the food I eat to taste good and be good for me.

    My journey with nutrition began in my mid-20s when I was pregnant with my now 16-year-old daughter. This was when I started to think about food, its purpose, and how to properly nourish my growing baby as well as myself. When my child, Izzy, began eating solid foods, I made my own baby food but was left mortified when she would spit out anything made with meat or fish. On the other hand, she would sing when I fed her vegetables or fruit. In a panic, I signed up for vegetarian cooking courses at George Brown College so that I could learn how to feed my growing vegetarian properly!

    I also searched for answers about how to eat without worrying about weight gain, feeling bloated, tired, or nauseous after a meal. I looked to find ways to balance my bouts of depression and anxiety, without the use of pharmaceuticals, which I discovered were linked to the lack of nutrients in my daily diet. This was when I decided to help others from my own experience by becoming a Registered Holistic Nutritionist from the Canadian School of Natural Nutrition.

    As a Holistic Nutritionist, I am very selective with the supplements choose for my own wellness as well as my clients'.  I look for Canadian brands that have integrity with their ingredient sources, unique formulations, as well as affordable pricing.
