Hey folks, it’s Dr. Sam and I received the question today – what is the best form of taking glutathione supplement?
The short answer is sublingual glutathione – this is the most highly bioavailable form and studies have shown it to most effectively absorb into the body. Sublingual means it is a spray that you put under your tongue and it absorbs through your mouth.
I want to point you to a 2015 study published in Biology Redox, where researchers took a group metabolically at-risk patients – these were patients who had cardiovascular disease and/or diabetes. They split them into three groups and gave them N-Acetyl-Cysteine in the form of a drug, glutathione in a liquid form, and glutathione in a sublingual form.
They used blood biomarkers to measure the oxidative stress in taking each form of glutathione and the results showed that the sublingual glutathione was by far the most bioavailable form that is best absorbed into the body.
So some great sources of glutathione include foods like spinach, avocado, okra, and asparagus. Generally speaking, look for foods that are rich in sulfur and selenium.
There are also studies that show if you sleep better, oxidative stress is reduced, and you increase your ability to better absorb nutrients like glutathione.
Exercise is also an important factor. Increase your exercise and you can better protect against oxidative stress.
So I really prefer the whole-health approach in boosting glutathione levels. There are number of things in terms of diet, exercise, and supplementation that can be done to boost glutathione levels, and these practices carry over and will have benefits for the entire body.
So that’s my message for today thank you so much for tuning in. And until next time take good care.
