L-GlutathioneAn increasing number of people are becoming more concerned about their health and well-being, taking steps to adopt a healthier lifestyle. According to a report from 2024, people in Britain are engaging with health and wellness, with 64% of people taking action to live more healthily.
This has led to an increased interest in exercise, healthy eating, and natural supplements. One of those supplements that people are becoming more aware of is glutathione.
We’re going to look at what glutathione is, what foods and lifestyle choices might have a detrimental effect on glutathione levels in your body and how you can maximise the benefits.
Glutathione is an antioxidant made up of three types of amino acids: glycine, cysteine, and glutamic acid. It is made in the liver, and as an antioxidant, it helps protect your cells from oxidative stress caused by free radicals.
Free radicals are unstable molecules that cause cell damage. If there is an imbalance in your body, this leads to oxidative stress, causing cell and tissue damage and contributing to chronic health conditions.
Glutathione has many benefits, with studies showing it has antiaging effects, slowing down the signs of ageing and making your skin healthier. It is involved in numerous other natural processes, helping with boosting your immune system, improving your cell function so you have more energy and helping to make the DNA.
This antioxidant in particular has piqued people’s interest in longevity and wellness because of its many uses, especially with how it supports cell function and regeneration processes. With all this, your body can perform better, and you’ll feel healthier.
Taking medications and supplements can be good for you, but sometimes they can get in the way of each other and reduce effectiveness. For glutathione to be effective, you’ll need to think about what else you are putting into your body.
Here are some vitamins and medications that may reduce the effects of glutathione supplements:
It’s not only what you are putting or not putting into your body that can impact glutathione levels. How you are living day-to-day can have a negative impact, meaning that supplements alone won’t help boost your glutathione levels. To really get the benefits, you need to make some lifestyle changes.
Lifestyle factors that could lower glutathione levels include:
As stated above, some foods will interfere with glutathione levels in your body.
The artificial additives and preservatives present in processed foods to prolong shelf life can affect the absorption of glutathione. They do this by affecting the digestion process, meaning that your body struggles to absorb nutrients, including glutathione.
Excessive sugar does this too. Even sweeteners, such as Aspartame, that are used instead of sugar in diet drinks and foods, can result in lower glutathione levels due to inflammation.
Even supplements can get in the way if overused. This is because overuse can lead to digestive issues, affecting absorption and causing oxidative stress. Also, excessive amounts of supplements mean your digestive system gets overwhelmed, and more glutathione gets broken down completely rather than absorbed.
Taking glutathione supplements at home is a good way to boost your levels, but it should just be part of your healthy living arsenal. There are many things you do, eat and drink to maximise the benefits of the boosted glutathione levels a supplement can provide for you.
It’s important to note that when making rapid lifestyle changes around your health, including taking supplements, you should seek medical guidance. Your doctor can offer you advice and ensure you are safe with the changes you are making and supplements you are taking.
Glutathione is a useful and versatile antioxidant and can help you increase your body’s potential. There are, however, foods, habits and even important medications that can reduce the benefits you may get.
