Cognitive decline is a gradual reduction in mental abilities including memory, thinking, and reasoning. It is caused by nutritional deficiencies in essential brain nutrients like omega-3 fatty acids (DHA), vitamin E, and selenium, which accelerate neurological deterioration. The Omega 3 and Omega 6 Fatty Acids test is the most important test for cognitive decline because low DHA levels are directly linked to Alzheimer's disease risk.

Cognitive decline is caused by nutritional deficiencies that starve the brain of essential nutrients needed for optimal function. Specifically, low levels of omega-3 fatty acids (particularly DHA), vitamin E deficiency, and inadequate selenium create an environment where brain cells cannot properly maintain their structure or protect themselves from oxidative damage. These deficiencies are frequently observed in patients with Alzheimer's disease and other forms of dementia, and research shows they directly accelerate the loss of memory, thinking, and reasoning abilities.
The Omega 3 and Omega 6 Fatty Acids test is the most important test for cognitive decline because it measures DHA (docosahexaenoic acid) levels, which are crucial components of brain tissue. Low DHA levels have been directly linked to an increased risk of Alzheimer's disease and accelerated cognitive deterioration. Additionally, the Vitamin E (Tocopherol) test is essential because vitamin E acts as a powerful antioxidant protecting brain cells from damage, and deficiencies are frequently seen in dementia patients. The Selenium test is also valuable, as lower selenium levels are associated with poorer cognitive performance and may contribute to the progression of mental decline.
You should get tested if you notice increasing forgetfulness, difficulty concentrating or making decisions, trouble finding the right words during conversations, or confusion about time and place. Testing is especially important if you have a family history of Alzheimer's disease or dementia, are over age 65, or have noticed your memory problems are affecting your daily activities like managing finances or following recipes. Early identification of nutritional deficiencies through blood testing allows you to address these factors before they contribute to further cognitive deterioration.

What this means
Your Omega-6 to Omega-3 ratio is elevated, indicating an imbalance that promotes inflammation in your body. While some omega-6 is necessary, this high ratio relative to omega-3s can increase your risk for cardiovascular disease, joint inflammation, and other inflammatory conditions. Improving this ratio through diet and supplementation can significantly benefit your heart health and reduce chronic inflammation.
Recommended actions
Eat fatty fish like salmon, sardines, or mackerel at least 2-3 times per week
Consider a high-quality omega-3 supplement (EPA/DHA) with 1000-2000mg daily
Reduce omega-6 rich oils like corn, soybean, and vegetable oils in cooking
Retest in 3-6 months to track improvement after dietary changes
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
