Frequently asked questions
NAC (N-Acetyl Cysteine) is valued for its antioxidant and detoxification support. It helps the body produce glutathione, a powerful antioxidant that protects cells from oxidative stress. NAC also supports liver health, respiratory function, and immune defence. Its ability to help maintain cellular health makes it a popular choice for overall wellbeing and healthy ageing.
NAC (N-Acetyl Cysteine) is best taken on an empty stomach, either first thing in the morning or between meals. This helps support optimal absorption. However, some people may prefer to take it with food if they experience any digestive sensitivity. If you're using NAC to support detoxification, immune health, or as part of a broader supplement routine, consistency is key. Take it at the same time each day for best results.
We recommend consulting with your healthcare professional before taking NAC during pregnancy or breastfeeding to ensure it is safe for you and your baby.
NAC (N-Acetyl Cysteine) is free from gluten, dairy, lactose, peanut, soy and egg.
NAC (N-Acetyl Cysteine) has a distinctive, slightly sulfur-like taste and smell, often described as sharp or tangy with a mildly bitter aftertaste. This is due to its sulfur content, which is also what gives it many of its beneficial antioxidant properties. While the taste is noticeable, NAC mixes easily into juice or flavoured drinks to help mask the flavour if taken as a powder. Capsules or tablets are a good option if you're sensitive to taste.
Yes, our NAC (N-Acetyl Cysteine) powder is 100% vegan friendly.
Blend 2 scoops (approx. 1g) into 150-200ml of water, juice or liquid of your choice.
NAC (N-Acetyl Cysteine) is generally well tolerated, but it may interact with certain medications due to its affect on the liver and detoxification pathways. If taking medications, we recommend speaking to your healthcare professional before starting.
NAC (N-Acetyl Cysteine) is generally considered safe for long-term use when taken at appropriate doses, but we recommend consulting your healthcare professional before starting any new long-term supplement regime.
NAC (N-Acetyl Cysteine) supports healthy ageing by helping to maintain the body’s natural antioxidant defences, particularly through its role in replenishing glutathione. Glutathione is one of the body’s most important antioxidants, involved in protecting cells from oxidative stress and supporting overall cellular health. By aiding in this process, NAC contributes to the body’s ability to manage daily stressors, support detoxification pathways, and maintain general wellbeing over time. These combined actions make it a valuable nutrient for those looking to support long-term health and vitality.
NAC (N-Acetyl Cysteine) supports cognitive function by helping to maintain healthy levels of glutathione in the brain, which plays a key role in protecting neurons from oxidative stress. It also supports healthy neurotransmitter activity, particularly involving glutamate, which is important for mood, focus, and mental clarity. By assisting these underlying pathways, NAC contributes to overall brain health and cognitive resilience.
