Testing vs. Guessing
Why Biomarkers Matter
Reading up on supplements or perusing social media, and you'll quickly find thousands of opinions about what you should be taking for your health: “Take 5,000 IU of vitamin D, take 2 grams of omega-3s… take magnesium, CoQ10… Take this, avoid that.” The problem? Most of these recommendations are based on averages, assumptions, or marketing — not on your unique biology.
The reality is that optimal health isn't achieved by guessing, it's achieved by testing. While we cannot test everything, we can accurately measure many things.
The Problem with Generic Recommendations
Two people can follow the exact same supplement routine and experience completely different results. One person may be deficient in vitamin D despite taking supplements daily. Another may already have optimal levels and gain little benefit from additional supplementation. One individual may need 3 grams of omega-3 fatty acids daily to improve cardiovascular markers. Another may reach optimal levels with half that amount. Without testing, you're essentially making educated guesses about what your body needs. And when it comes to long-term health, guessing can become expensive, ineffective, and sometimes even counterproductive.
Vitamin D & Omega 3s Are Perfect Examples
Vitamin D are omega 3s are some of the most commonly recommended supplements, yet few people know their actual status. Rather than asking “how much should I take,” a better starting question is “what are my vitamin D/omega 3 levels to begin with?"
A blood test measuring vitamin D/omega 3s can reveal whether your individual levels are deficient, insufficient, optimal, or potentially taking too high. Instead of randomly choosing a dose, testing allows supplementation to become personalized and goal-oriented. The result is a more efficient path to achieving optimal levels while avoiding unnecessary supplementation.
Looking Beyond Traditional Cholesterol Tests
For decades, standard cholesterol panels have been used to evaluate cardiovascular risk. To be honest, if you have family history of heart disease, wouldn’t you like to learn the BEST test options to provide the BEST information of your actual risk? While useful, they often tell only part of the story.
Many individuals with "normal" cholesterol levels still develop heart disease, in fact, according to Harvard Health; 50% of heart attacks have normal cholesterol levels. This has led researchers and preventive medicine practitioners to focus on biomarkers that are better indicators. Here is one example….
Apolipoprotein B: The Particle That Matters
Apolipoprotein B (ApoB) measures the number of potentially atherogenic lipoprotein particles circulating in the bloodstream.
Think of it this way: traditional LDL cholesterol measures how much cholesterol is being carried. ApoB measures how many particles are carrying that cholesterol. Because one risk factor that matters is number of particles, ApoB is one marker that provides a more direct estimate of the particles that can contribute to plaque formation.
Many experts now consider ApoB one of the most important cardiovascular risk markers available. Knowing your ApoB level can help guide lifestyle interventions, dietary changes, supplement strategies, and conversations with healthcare providers.
The Future of Preventive Health
Functional medicine has always focused on root cause therapy while empowering the client. A proactive approach will always outperform reactive one. Instead of waiting for disease to develop, we now have access to biomarkers that can identify imbalances, nutrient deficiencies, and potential risks long before symptoms appear.
Testing allows us to answer critical questions about dosage, intervention efficacy, and health risks. These insights help transform wellness from a guessing game into a measurable, personalized strategy.
Test. Optimize. Retest.
The most effective health plans follow a simple framework:
Test to establish a baseline.
Implement targeted interventions.
Retest to measure progress.
Adjust based on results.
Whether you're focused on longevity, heart health, energy, cognitive performance, or disease prevention, objective biomarkers provide the roadmap. When it comes to your health, the goal shouldn't be to do more, the goal should be to do what works; and the best way to know what to do (or what is working) is to test.
