What's this test for?

This test is ideal if you're concerned about oxidative stress, frequent illness, chronic fatigue, or exposure to toxins and pollutants. It measures your glutathione levels, which is your body's most powerful antioxidant that protects cells from damage and supports detoxification. Many people use this test when they want to understand their body's ability to fight free radicals, recover from illness, or optimize their antioxidant defenses.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your glutathione levels mean for your immune function, cellular protection, and detoxification capacity. These notes include personalized recommendations like dietary changes, supplement suggestions for boosting glutathione naturally, and lifestyle modifications to reduce oxidative stress. You'll also get the standard lab report and can track your glutathione levels over time using our trends feature to see how your interventions are working.

What's included in this test?

This test measures Glutathione (total). This test measures your total glutathione levels, which reveals how well your cells are protected against oxidative damage from daily stress, pollution, illness, and aging. Glutathione is your body's master antioxidant that neutralizes harmful free radicals, supports liver detoxification, strengthens immune function, and helps repair cellular damage. Low levels may indicate increased vulnerability to oxidative stress and reduced ability to eliminate toxins effectively.

How should I prepare for this test?

No fasting is needed for this test. You can eat and drink normally before your blood draw. Simply schedule your appointment at a convenient time and visit the lab for a quick blood sample collection.

Who should consider getting this test?

This test is valuable for anyone experiencing chronic fatigue, frequent infections, or slow recovery from illness. It's also important for people exposed to environmental toxins, heavy metals, or pollution, those with chronic health conditions, athletes looking to optimize recovery, and anyone interested in anti-aging strategies. People taking medications that may deplete glutathione or those with poor dietary habits may also benefit from checking their levels.

What symptoms indicate I may need this test?

Common signs of low glutathione include persistent fatigue that doesn't improve with rest, frequent colds or infections, slow wound healing, and brain fog or difficulty concentrating. You might also experience muscle weakness, joint pain, sensitivity to chemicals or strong smells, or premature signs of aging like dull skin. If you're dealing with chronic health issues or feel your body isn't recovering well from stress or illness, this test can provide valuable insights.

How can I naturally support my glutathione levels?

You can boost glutathione naturally by eating sulfur-rich foods like garlic, onions, cruciferous vegetables, and eggs. Foods high in vitamin C like citrus fruits and berries, along with selenium-rich foods like Brazil nuts and fish, also support glutathione production. Regular exercise, quality sleep, reducing alcohol consumption, and minimizing exposure to toxins help preserve glutathione. Consider supplements like N-acetyl cysteine (NAC), alpha-lipoic acid, or milk thistle after consulting with a healthcare provider.

What is glutathione and why does it matter?

Glutathione is your body's most abundant and powerful antioxidant, often called the master antioxidant because it protects every cell in your body. It neutralizes harmful free radicals, supports your liver in removing toxins, strengthens your immune system, and helps repair damaged cells. Adequate glutathione levels are essential for healthy aging, disease prevention, energy production, and maintaining optimal health. When levels drop, you become more vulnerable to oxidative stress, illness, and cellular damage.

What does low glutathione mean?

Low glutathione levels indicate your body's antioxidant defenses are compromised, making your cells more vulnerable to oxidative damage. This can result from poor nutrition, chronic stress, aging, illness, toxin exposure, or certain medications. Low levels are associated with increased fatigue, weakened immunity, slower recovery, inflammation, and higher risk for chronic diseases. It means your body may be struggling to effectively neutralize free radicals and eliminate toxins.

How often should I retest my glutathione levels?

If you're working to improve low glutathione levels through diet, supplements, or lifestyle changes, retesting every 3-6 months helps track your progress. Once your levels are optimized, annual testing is reasonable for maintenance monitoring. If you're dealing with chronic illness, undergoing treatment that may affect glutathione, or exposed to significant environmental toxins, your healthcare provider may recommend more frequent testing every 2-3 months.
