Alzheimer’s disease is one of the most pressing health challenges facing aging populations. As a progressive neurodegenerative disorder, it leads to memory loss, cognitive decline, and impacts the ability to carry out daily tasks. While there’s no known cure, research is increasingly showing how nutrition and proactive health monitoring may reduce risk and delay onset.
Among the most compelling findings: biomarkers like Omega-3 fatty acids, homocysteine, glutathione, vitamin D, and HbA1c can offer early insight into brain health—and give you the chance to intervene.
🧠 Omega-3 Fatty Acids and Brain Function
Omega-3 fatty acids—particularly DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid)—are vital for cognitive function. DHA is a structural building block of brain cell membranes, supporting learning, memory, and neuronal protection. Low levels of DHA are associated with higher risk of Alzheimer’s and cognitive decline.
🔬 A 2022 meta-analysis published in Nutrients found that higher Omega-3 Index levels were significantly associated with slower cognitive decline in older adults.

📊 Track your levels with our Omega-3 Index Test—a simple at-home blood test that quantifies EPA and DHA in red blood cells.
🧪 Homocysteine: A Neurovascular Risk Marker
Homocysteine is an amino acid that, when elevated, contributes to oxidative stress, blood vessel damage, and brain atrophy. High homocysteine is now considered a modifiable risk factor for Alzheimer’s disease.
🔬 A longitudinal study in Neurology (2019) found that individuals with high homocysteine had nearly double the risk of developing Alzheimer’s over 10 years.

✅ Our Homocysteine At Home Test helps you track your levels so you can take action with B-vitamin support (folate, B6, B12).
🛡️ Glutathione: The Brain’s Defense Against Oxidative Stress
Glutathione is your body’s master antioxidant. It protects brain cells from free radical damage—a major driver of neurodegeneration.
🔬 Research from the Journal of Alzheimer’s Disease (2020) noted that Alzheimer’s patients often have depleted brain glutathione levels, leaving neurons vulnerable to oxidative harm.
🧬 You can assess your antioxidant status with our Glutathione Index Test, using just a few drops of blood from home.
☀️ Vitamin D: Cognitive Protector
Vitamin D is known for bone health, but it also supports brain function by modulating neurotransmitters and reducing inflammation. Low vitamin D is linked to higher dementia risk.
🔬 A large-scale 2022 study in the American Journal of Clinical Nutrition found a 40% increased risk of dementia in those with low vitamin D levels.
☀️ Track your levels with our Vitamin D Test, which measures both D2 and D3 forms for complete status.
🔢 HbA1c: The Blood Sugar–Brain Health Connection
HbA1c reflects your average blood glucose over 2–3 months. Chronically elevated HbA1c can promote insulin resistance in the brain—a hallmark of Alzheimer’s that’s earned the nickname “Type 3 diabetes.”
🔬 A 2021 analysis in the Journal of Alzheimer’s Disease showed that individuals with higher HbA1c had greater hippocampal atrophy and poorer memory performance.
🧪 Use our HbA1c Test to monitor blood sugar and catch metabolic issues early.
🧬 Take Control of Your Brain Health
Alzheimer’s risk is shaped by many factors, but the five biomarkers above offer actionable insight. Testing these markers doesn’t just offer a snapshot—it empowers you to make informed changes to your diet, supplements, and lifestyle.
With our at-home tests, you can take control from the comfort of your home. Early detection leads to earlier intervention—and that could mean better cognitive function for longer.

🧠 FAQs
Q: What biomarkers are linked to Alzheimer’s risk?
A: Omega-3 Index, Homocysteine, Glutathione, Vitamin D, and HbA1c are key blood biomarkers shown to impact cognitive decline and Alzheimer’s risk.
Q: Can Omega-3s reduce Alzheimer’s risk?
A: Yes, especially DHA and EPA. Studies show higher Omega-3 levels are linked to better memory and slower cognitive aging.
Q: What is the best way to monitor brain health proactively?
A: Use at-home tests to track inflammation (Omega-3, Homocysteine), antioxidant status (Glutathione), blood sugar (HbA1c), and vitamin D levels regularly.
