Ever feel like you're doomed to a life of taking the equivalent of your bodyweight in supplements everyday? Ever wish there was one supplement you could take that could do everything you want a supplement to do just so you didn't have to spend five minutes everyday downing capsules and measuring teaspoons and leveling powders? Well, there's not.

But there is one supplement that comes close. How close?

Close enough for us to write this passionate but not prejudice article on its benefits. We're talking about NAC, folks: a seldom praised, but always amazing supplement that can help improve mental and physical health in a myriad of astonishing ways. And we're not just saying this either: NAC is a supplement that has been well-researched, and the perks are proven.

Let's talk more about those perks. But first, let's get a better feel of what NAC is, exactly.

NAC stands for N-Acetyl-Cysteine and is a form of the essential amino acid cysteine. Your body uses cysteine to produce an insanely important antioxidant called glutathione -- also known as GSH. It's NAC's ability to bolster your body's production of GSH that's the source of this supplement's real superpowers. NAC has been shown to increase blood levels of GSH, and therefore, bolsters all the benefits that come with its antioxidant prowess.

How?

Inflammation, friends. Inflammation. NAC regulates gene expression that affects the process of inflammation. Specifically, it stops the expression of cytokines, which cause inflammation, while also hindering NF-kappa B, and controls COX-2 -- another pro-inflammation chemical. By regulating and even suppressing inflammation in your body, NAC can help assuage many diseases and conditions that have inflammation at their root. And that's a lot. Like, hundreds. But we'll stick to discussing the big ones.

NAC Helps Detoxification

NAC can protect your body from toxins. It has a favorable content of sulfhydryl groups, which bind to toxins like mercury, lead, cadmium,  herbicides, environmental pollutants, as well as microbes such as carbon tetrachloride, aflatoxin and E.coli. What's more, it can even bind to acetaminophen to aid in preventing liver damage due to acetaminophen (Tylenol) overdose or poisoning. In fact, in general it's been shown to be a major boon to liver health, not only protecting liver cells, but healing damaged cells.

NAC Supports Weight Loss

By improving insulin resistance, NAC supports metabolic health, which can result in weight loss, while also improving conditions like hypoglycemia and diabetes.

NAC Increases Athletic Performance

Through reducing inflammation caused by training, studies have shown that NAC can help people bounce back faster after workouts, and perform better during their workouts.

NAC Supports Heart Health

NAC can stop bad cholesterol (i.e. LDL-cholesterol) from oxidizing and causing inflamed blood vessels. It's also been shown to lower homocysteine levels, which ultimately prevents plaque build-up in arteries.

NAC Helps Mental Health

GSH has been shown to help treat various psychological and mental conditions, including autism and Alzheimer's disease, as well as anxiety disorders like obsessive compulsive disorder. Supplementing can be used as an effective strategy to help people with these conditions better cope.

Studies also suggest that NAC can be particularly effective when it comes to treating addiction to drugs including cocaine, nicotine and alcohol, and could be successfully used in addition to a detox program.

NAC Supports Gut Health

Because NAC has been shown to be able to deactivating H.Pylori -- a bacteria that can cause ulcers, reflux disorders, gastritis and even some types of gastrointestinal cancers, many healthcare professionals have recommended adding NAC to treating H.Pylori infections that are resistant to antibiotics.

What's more, NAC can help reduce inflammation in the kidney due to kidney disease, and therefore help alleviate conditions.

Amazing, right? And these are only some of the perks of taking NAC. It can also improve respiratory health, and even fight back the hands of time thanks to its skin beautifying antioxidants.

NAC definitely pulls its weight in the world of supplements and ranks as one of our top must-haves. Just be warned: don’t swap GSH for NAC. Using a GSH supplement won’t give you the same positive effects, since oral GSH is rendered useless thanks to stomach acid, whereas, NAC, on the other hand, is not.

How much NAC should you take?

NAC has an incredibly safe track-record, but before you start taking any supplement, first talk to your health care professional. If you’re given the green light and are not given an exact dosage by your doctor or other professional, it’s good to start at 600 mg, and work your up to as much as 3000 mg daily. Take with vitamin C for optimal absorption.

Meant to add: you should be able to get NAC in Canada in most natural health care shops or training supplement stores. I’m in Canada and have never had an issue finding it. Amazon works too.

As for how long one can take it, speak to your healthcare provider. Mine said I could take it indefinitely but everyone is different. :)

I’ve been taking NAC for a while now, along with many other supplements. They were recommended by my acupuncturist to promote fertility. I have never had such great mind clarity since beginning my new supplement regimen.

Shipping & Delivery

Due to COVID-19, shipping systems the world over are experiencing abnormal delays. There is an enormous demand on postal and delivery services as online shopping has skyrocketed, due to store closures and stay-at-home mandates. This is an unprecedented situation, and we are working around the clock to fulfill your orders as quickly as possible. To be clear, we are filling orders in 4-6 days, and we are shipping immediately after that. Once shipped, our shipping partner, UPS, will get your order out to you as quickly as possible. Thanks for your support and understanding.

Are you in Canada? Specifically, are you outside of a metropolitan centre? We need to alert you to a disruption in shipping due to COVID-19. Our preferred shipping provider, UPS, has informed us that they cannot guarantee express shipping for many locations. We have also seen that packages delivered to Toronto, Ottawa, Vancouver, etc, are not waylaid, but packages delivered to areas just outside of these cities are being held in transit for days or even weeks. UPS has discontinued their guarantee of 1-4 day delivery, which you can read more about here. Therefore, we can guarantee early fulfillment but not early delivery of our goods from our warehouse to your door at this time.

 

We want you to start your fitness journey with us as quickly as possible, that’s why we send every package to the USA & Canada via expedited or standard shipping with our partners at UPS. Once your order is received and processed, it typically takes 2-4 days to get to you once it leaves our warehouse. That’s our commitment and we stand by it.

We ship within Canada and the United States via UPS with Standard & Expedited shipping (whichever is faster)

For locations outside of the US and Canada, we ship using FedEx International (EUROPE and Other Nations), which is usually in transit for 7-10 business days, depending on location.

We ship all of our physical products with UPS, from our warehouse location in Kingston, Ontario, Canada. Delays caused due to custom withholds are not included in these estimated delivery times.

Returns & Exchanges

BodyRock Equipment

We offer a 30-day return policy, as long as: it is not more than 30 days past the date of delivery; and your item is in its original condition and packaging with the original order number. Refunds will be issued when the equipment is received back to the BodyRock warehouse, minus the original cost of shipping, and the customer is responsible for the costs of return shipping. To request a refund on physical product purchases, please contact us.

Digital Products

We cannot issue refunds on digital goods such as e-books or videos, as these are non-tangible goods that are irrevocable once the order is placed.

Clothing

All of the BodyRock clothing is made to order and so is final sale. If you have any questions about sizing prior to placing your order, please contact us.
