Why a glutathione blood test may be important for low vitamin D levels
Are you struggling to increase your vitamin D levels, even with supplements? You're not the only one. There is growing scientific interest in the role of glutathione, an important antioxidant, in regulating vitamin D levels in the body. Recent research shows that glutathione deficiency may be the cause of a lack of response to vitamin D supplements.
The link between glutathione and vitamin D
Vitamin D plays a vital role in everything from bone health, fatigue and the immune system. Normally vitamin D is produced in the skin by sunlight, taken through supplements and found in oily fish, such as sardines, herring, salmon and mackerel, after which it is converted by several steps in the body into the active form, which provides the health benefits. This process depends on certain enzymes that are regulated by glutathione.
When glutathione levels are low, as is often the case in people with chronic diseases or obesity and less common in healthy individuals, this conversion can become impaired. As a result, the body fails to convert vitamin D effectively, even with high doses of supplements.
Support with glutathione
New research suggests that supplementation with glutathione or the precursor (precursor) N-acetylcysteine (NAC) may have a positive effect on improving vitamin D function. By stimulating glutathione production, the enzymes responsible for vitamin D conversion may function better. This may help to still increase vitamin D levels in people who appear to be resistant to vitamin D supplementation alone.
Glutathione blood test
Because glutathione plays such a crucial role in this process, it is wise to have your glutathione levels checked in addition to a vitamin D test. With this information, you can better understand why your vitamin D levels may not be rising. You can then work with an orthomolecular therapist/dietitian to take targeted steps to improve your health. Consider, among other things, a balanced diet that contains enough nutrients to support glutathione metabolism. In some cases, additional supplementation may provide relief. It is always advisable to seek advice from a health care provider before taking supplements.
Conclusion
If you find that your vitamin D levels are not rising despite supplements, a glutathione blood test may help. This can be an important step in supporting not only your vitamin D levels, but also your overall health.
