Oxidative stress happens when the amount of free radicals exceeds the amount of antioxidants. That’s when oxidation damages our cells, proteins and our DNA (genes).

Frequently Asked Questions

What is GLYNAC?
GLYNAC is a blend of two amino acids, NAC (N-acetylcysteine) and Glycine. This combination is an approach to support the body's natural detoxification processes and the body's natural response to oxidative stress.
What is Oxidative Stress and where does it come from?
Oxidative stress is an imbalance between free radicals and antioxidants in the body, leading to potential damage to cells, proteins, and DNA, which may contribute to various health issues. It happens when the amount of free radicals exceeds the amount of antioxidants. Oxidation increases when we are exposed to stress, toxins, and infections. It is also increased by sugar and chemicals, so the more you can minimize your exposure to these things, the better. That’s when oxidation damages our cells, proteins and our DNA (genes). Oxidative stress plays an essential role in the development of chronic diseases such as cardiovascular diseases, diabetes, neurodegenerative diseases, and cancer. Long term exposure to increased levels of pro-oxidant factors can cause structural defects at a mitochondrial DNA level, as well as functional alteration of several enzymes and cellular structures leading to aberrations in gene expression. The modern lifestyle associated with processed food, exposure to a wide range of chemicals and lack of exercise plays an important role in oxidative stress induction.
How are your Glutathione levels affected?
As we age, our glutathione stores are depleted, and oxidative stress increases. By the time you are 60, your body produces half the levels of glutathione that it did in yours 20s. As a result, your energy starts flagging and your immunity is lowered. Glutathione is the single most powerful anti-oxidant your body produces and recycles, It's made in the liver, the organ most responsible for detoxifying your body, so optimal liver function is absolutely essential. If your liver isn't functioning well, glutathione production suffers, toxins overwhelm it, and illness, both short term and long, are not far behind.
Is Glutathione contained in natural foods and sources?
The body produces glutathione, but there are also many foods that do too. Spinach, avocados, asparagus and okra are some of prevalent natural sources. However, to get the levels of Glutathione we need from those foods, we would need to eat huge amounts, which is when supplementation comes in to help.
What are the benefits of GLYNAC (NAC & Glycine)?
GLYNAC helps to keep your mitochondria pumping out energy, neutralises and removes heavy toxins from the body and protects your DNA from oxidative stress. It also helps to support a healthy immune system, improve cognitive and physical function and supports healthy ageing overall for an improved quality of life.
Does GLYNAC (NAC & Glycine) support brain health?
As GLYNAC helps to boost Glutathione levels, natural Glutathione is the brain's universal antioxidant. This in turn helps with brain fog, aid in reducing inflammation on the brain and generally promotes brain health.
Is the Youth & Earth GLYNAC (NAC & Glycine) vegan and gluten-free?
Yes, our GLYNAC supplement is suitable for vegans and vegetarians. It is also gluten-free and free from GMOs, nasty fillers and additives.
