Why You Should Check Your Bloods: The Key to Staying Strong and Healthy

When it comes to wellness, we often focus on what’s visible: what we eat, how much we exercise, how well we sleep, and even how much stress we’re under. And while these factors are crucial, they’re not the whole picture. The truth is, much of what determines your health is happening silently in your bloodstream.

Blood tests are one of the most powerful and underutilised tools we have in modern and functional medicine. They provide a detailed snapshot of what’s going on inside your body—far beyond what you can see or feel. If you’re serious about staying strong, healthy, and ahead of illness, checking your blood regularly should be a core part of your wellness strategy.

Why Blood Tests Matter More Than You Think

Blood tests can reveal imbalances, deficiencies, infections, and early warning signs of chronic disease before symptoms appear. Think of it as your body’s internal feedback system. Without it, you’re flying blind.

Here’s what regular blood work can help you catch early:

• Nutrient Deficiencies: Even with a clean diet, many people are low in critical nutrients like iron, B12, folate, vitamin D, and magnesium—often without knowing it.

• Inflammation and Oxidative Stress: Chronic inflammation is now linked to everything from arthritis to heart disease to depression. Blood markers like CRP (C-reactive protein) can warn you well in advance.

• Hormonal Imbalances: Stress, poor sleep, environmental toxins, and ageing can wreak havoc on hormones like cortisol, testosterone, oestrogen, and thyroid function.

• Organ Health: Liver and kidney markers can show stress or damage before symptoms arise. Early detection often means full recovery.

• Cholesterol and Blood Sugar: These two numbers are more than just heart health metrics—they’re central to metabolic wellbeing and disease prevention.

The Functional Medicine Viewpoint: Looking Deeper Than “Normal”

Most people are familiar with the idea of getting their blood tested during a medical check-up. But there's a big difference between being told your results are “within normal range” and truly understanding what’s optimal for your body.

Functional medicine doesn’t just look at whether your numbers are normal—it looks at whether they’re ideal. It also considers patterns and trends, not just isolated numbers. That’s why even people who feel well can benefit from blood testing: you may be running below optimal without realising it.

At Sebastian Siebert Supplements, we often see patients who’ve been dismissed by conventional medicine, only to discover through blood testing that they are low in essential minerals, showing signs of gut permeability, or living with silent inflammation that’s blocking progress in their health goals.

When and How Often Should You Test?

The answer depends on your age, health status, and lifestyle. As a general guide:

• Annually: For healthy adults with no known medical conditions, a comprehensive blood panel once a year is a smart baseline.

• Every 6 months: If you’re on supplements, medication, or undergoing a wellness protocol (such as detox, gut healing, or hormone balancing), test more frequently to track your progress.

• Quarterly: For those with chronic illness, autoimmunity, or intense athletic training.

What to Test For: The Essentials

Here’s a short list of the most useful markers to include in your panel:

• Full Blood Count (FBC): Basic immune and oxygenation health

• CRP and ESR: Inflammatory markers

• Vitamin D3 and B12: Key for immunity and energy

• Ferritin and Iron Panel: To detect low or high iron stores

• Homocysteine: A marker of cardiovascular and brain health

• Liver Function Test (LFT) and Kidney Function Test (KFT)

• Thyroid Panel: TSH, T3, T4, Reverse T3, and thyroid antibodies

• HbA1c and Fasting Glucose: Blood sugar balance

• Lipid Profile: Cholesterol, HDL, LDL, triglycerides

• Electrolytes and Minerals: Magnesium, potassium, calcium, and sodium

In functional medicine, we often add gut health markers, heavy metals, and hormone panels (like DHEA, cortisol, and sex hormones) to build a bigger picture.

Why Waiting for Symptoms is a Mistake

Symptoms are often the last sign that something is wrong. Many diseases begin with subtle internal shifts that aren’t detectable without a lab test. By the time fatigue, poor sleep, or skin breakouts show up, the imbalance may already be deeply rooted.

Testing gives you the power to prevent, not just react.

It also gives you clarity when making decisions about lifestyle changes or supplements. Instead of guessing what to take, you can use your results to guide your regimen precisely—saving time, money, and energy.

Supplements Are Powerful—But So Is Data

Our flagship supplements, FLORISH Spore Probiotic with Fulvic Acid and FULFIXER Fulvic Acid, are designed to support nutrient absorption, cellular detox, and gut health. But even the best supplements work better when they’re used strategically.

For example, if your bloodwork shows low vitamin D or poor mineral absorption, fulvic acid can enhance uptake. If chronic inflammation is present, spore-based probiotics can modulate your immune response and reduce gut permeability. But without testing, you’re relying on assumptions.

We believe in pairing intelligent supplementation with insight.

Don’t Fear the Needle—Embrace the Knowledge

There’s still a strange cultural resistance to regular blood testing. Many people only test when they’re sick, or they avoid it altogether out of fear of bad news. But if you want to stay strong, age well, and remain fully in charge of your health, regular blood work is one of the smartest things you can do.

It’s not about paranoia—it’s about proactive wellness.

Next Steps

If it’s been more than a year since your last full panel—or if you’ve never done one—now is the time. Pair your results with targeted support from the Sebastian Siebert Supplements range and work with a practitioner who understands how to interpret them through a functional lens.

Being healthy isn’t just about doing more—it’s about knowing more. And your blood has the answers.
