Impact NAC
You can eat well, train consistently, and still feel like your body isn't bouncing back the way it used to. That often comes down to your body's natural antioxidant system, which depends on one essential ingredient: NAC. Formulated with 600 mg of high-purity NAC per capsule. Thoughtfully formulated. Nothing added that doesn't need to be there.
Suitable for healthy adults. If you are taking anticoagulant (blood-thinning) medication, do not use this product unless advised by your healthcare professional. If you are pregnant, breastfeeding, have a medical condition, or are taking prescription medication, consult your healthcare professional before use. Always read the label and use only as directed. See our FAQs below for more information.
"Since I started taking NAC, I feel like I recover better after hard training sessions. I don't feel as sore, and my body feels stronger and more ready for my next ride."
Why N-Acetyl Cysteine (NAC) matters.
Everyday stress, poor sleep, illness and ageing all reduce the raw materials your body needs to produce glutathione, so its natural defences can struggle to keep up.
NAC (N-Acetyl Cysteine) supplies the raw material your body uses to produce glutathione, its most important antioxidant. Without enough cysteine, your body simply can't make enough of it.
Glutathione is your body's most important antioxidant. It helps protect your cells from everyday physical and environmental stress, but your body can only make it if it has enough cysteine, which NAC provides.
Stress, poor sleep, illness and ageing can reduce your body's ability to produce it. NAC supports natural production, helping maintain your own antioxidant defences.
It doesn't contain glutathione. That's exactly the point.
Taking glutathione directly isn't the answer. Your body breaks it down before it can be used. NAC works differently. It gives your body what it needs to produce its own glutathione naturally.
Supporting you every day.
Once your body has the raw material it needs, it can continue doing what it was designed to do, protecting and supporting your cells every day.
Helps maintain your body's natural antioxidant defences against everyday physical and environmental stress.
Physical training and sustained mental effort place extra demands on your body. NAC supports your body's natural recovery processes after everyday physical and cognitive stress.
Helps maintain your body's natural antioxidant defences as part of a healthy lifestyle.
Not all NAC is created equal.
Not all NAC supplements are created equal. The quality of the ingredient, the purity of the formula, and what isn't added all influence the final product.

Why clinicians choose Impact NAC
Every capsule contains exactly what it needs to, and nothing it doesn't.
Built from one clinician's experience, not a supplement catalogue.
Helen Tufui is the Founder of The Headache Clinic, New Zealand's first dedicated headache and migraine clinic network, and now the country's largest network of headache clinicians.
NAC found its way into the Impact Neuro Health range through Helen's own patients. She wanted to offer them a high-quality supplement made specifically to support the brain, NZ formulated and NZ made with no fillers, backed by science, and held to a standard she could stand behind.
This isn't a product manufactured overseas with a local label. Impact NAC is conceived, formulated, and produced here, by a clinician who recommends it to her patients daily and holds it to the standard she'd set for herself.
Helen's work extends well beyond supplements.

Speaker · Entrepreneur · Advocate
Helen trained as a physiotherapist and was running her own practice in Auckland before relocating home to Southland. It was there, after experiencing a concussion herself, that she saw firsthand what it's like to live with persistent headaches and no clear answers.
What started as a single clinic in Invercargill has since grown into a nationwide network, and the same drive to close gaps in patient care led to the Impact Neuro Health supplement range, including Impact Magnesium and Impact NAC, the NAP Pillow, and the soon-to-be-released HIT Kit®. Over 15,000+ hours of clinical practice, Helen kept identifying gaps that nothing on the market was filling, so she built the solutions herself.
