It's name may not roll off your tongue( !),  and unlike Vitamin C your mum won't have mentioned it to you, but actually, N-Acetyl-Cysteine  NAC  Lee (or OptiNac as we like to call it) is an amazing  and versatile nutritional supplement  that can be applied to so many  chronic health problems  faced by people in the modern world.

What is NAC?

N-acetyl cysteine (NAC) is a modified form of  the Amino acid cysteine. Cysteine  itself is found in many high-protein foods, including meats, yogurt, lentils, cheese, eggs, sunflower seeds and legumes. But importantly the incy wincy chemical modification in NAC actually makes a massive difference as it become highly bioavailable in the body - making a very useful  for a variety of challenges. 

Why is NAC Important to Nutrition? What does NAC do?

NAC has been shown to help a variety of symptoms and is, in fact, used in hospitals as well!


  • Lungs - NAC Helps chronic lung conditions like asthma and Chronic Obstructive Pulmonary Disease (COPD). There is some preliminary evidence showing it also helps  outcomes with conditions associated with  lung affecting diseases like coronavirus.
  • Liver - Improves liver problems like fatty liver and alcohol damage.
  • Sexual Health - NAC is  helpful for issues with sperm count and  Polycystic Ovary Syndrome (PCOS) where controls sugar levels)
  • OCD and BFRBs - It has been proven to help certain forms of OCD, particularly those in the Body Focused Repetitive Behaviours category; like trichotillomania (hair pulling), dermatophagia (skin picking) and onychophagia (nail biting)
  • Skin - It can improve skin health and complexion by aiding in the production of collagen and promoting skin elasticity and improving the texture of the skin
  • Fitness - Studies indicate it  improved athletic performance
  • Heart problems - like angina are alleviated. 
  • There is also preliminary evidence to suggest that it may help to prevent colon cancer Some experts believe that NAC increases the efficacy of chemotherapy drugs and helps to alleviate their side effects, however there is little clinical evidence to support this. 
  • Poisoning - Very high doses of NAC are given to patients in hospital to treat acetaminophen Paracetamol/tylenol/Panadol poisoning, as overdoses of paracetamol cause the liver to get poisoned.

So what happens if you don't get enough NAC?


Whilst NAC is not typically though of as a vitamin and is sometimes seen as “non-essential”,  it is still a very important amino acid in the body and a deficiency of NAC can have noticeable symptoms, like:


  • Apathy and lethargy
  • Loss of pigmentation in hair
  • Edema (swelling)
  • Liver damage
  • Muscle loss
  • Skin lesions
  • Weakness 

Consuming adequate NAC is important for a variety of health reasons — including replenishing glutathione, considered by many to be the most  powerful antioxidant in the body.  


Why Optinac?


We have developed and sourced a version of NAC in Optinac which is is manufactured in Great Britain and where we can control the quality of the supplement in a quality controlled factory unlike many of the supplements on the market which are simply Indian or Chinese imports. We also believe our dosing of 600mg  is neither too high or too low and just right for the majority of customers.


So what's the best way to supplement with Optinac?

  • You can swallow a NAC tablet with water
  • You can also have it with vitamin C - which is also an antioxidant. This may enhance its effects.


Will taking a higher strength dose of NAC cause you any harm?

  • When you think about it, NAC is a food substance being an amino acid.  There are no severe side effects reported as it is a highly tolerated protein component, but a maximum dose of 1800 mg/day should not be exceeded without advice from your health practitioners.
