Your Labs Are “Normal”… So Why Do You Still Feel Terrible?
One of the biggest frustrations that leads patients away from conventional medicine and into my office is the experience of feeling deeply unwell, but being told everything looks fine in their testing. Many people are left feeling helpless, and they are looking for answers. Our maxed out medical system simply does not have the capacity currently to work with people on achieving their optimal health, and instead is fighting a battle just to help those who are critical.
The answer to many is a mystery as to “what is wrong with me?” The reality is that there’s often a big difference between what the medical system considers “normal” lab ranges and the optimal levels for how your body actually functions.
Standard lab ranges are designed to detect disease and severe deficiencies, not to identify the early imbalances that can impact energy, mood, metabolism, hormones, and overall wellbeing.
Here are a few common key tests where “normal” may not always mean optimal.
Vitamin B12
A common culprit for low energy, Vitamin B12 is essential for energy production, nervous system health, brain function, and red blood cell formation.
Signs that your B12 levels may be suboptimal:
Fatigue
Brain fog
Tingling or numbness
Low mood or anxiety
Poor concentration
Weakness.
Things like low stomach acid, gut inflammation, vegetarian diets, stress, aging, and certain medications can all impact dietary absorption of B12 and supplementation can be highly beneficial in these cases.
Ferritin
Ferritin is something we test to measure your stored iron… and this is a huge one for menstruating women.
You can technically have “normal” hemoglobin while still having depleted iron stores and be left feeling awful.
Low ferritin can contribute to:
Fatigue
Hair shedding
Dizziness
Anxiety or low mood
Poor exercise tolerance
Feeling cold
Restless legs
Many people begin noticing symptoms long before ferritin reaches the bottom of the lab range. Heavy periods, restrictive diets, gut issues, and chronic stress can all contribute to low iron stores over time.
Always consult with your healthcare provider before supplementing iron.
Thyroid
Thyroid health is one of the most frustratingly overlooked pieces of the fatigue puzzle.
Most people are told their thyroid is normal because their TSH falls within range, and conventional testing stops there.. but thyroid function is more complex than one single marker.
Additional markers can provide a more complete picture:
Free T3
Free T4
Thyroid antibodies
Symptoms of poor thyroid function may include:
Fatigue
Weight gain or difficulty losing weight
Dry skin
Hair loss
Depression
Constipation
Feeling cold
Low motivation
Stress, nutrient deficiencies, inflammation, and autoimmune activity can all impact thyroid function.
Insulin & A1C
Blood sugar imbalance doesn’t happen overnight. Many people experience symptoms of insulin resistance years before they develop diabetes, and catching this early can allow us to reverse the process and prevent further development.
Signs of insulin resistance include:
Energy crashes
Sugar cravings
Brain fog
Increased belly fat
Mood swings
Feeling shaky when hungry
Afternoon fatigue
Conventional testing looks at fasting glucose, or A1C, which may still appear “normal” while insulin levels are elevated behind the scenes. Looking at insulin earlier can help identify patterns before more serious metabolic issues develop.
Vitamin D
Vitamin D impacts far more than bone health. It plays a role in immune function, mood, hormone regulation, energy levels, and muscle function. Low vitamin D is incredibly common especially in Canada with our dark winter months.
Symptoms of low Vitamin D look like:
Fatigue
Frequent illness
Low mood
Muscle aches
Poor recovery
Low immunity
Many people feel significantly better when levels are brought into a more optimal range rather than simply avoiding deficiency, and I recommend that most people consider supplementing with Vitamin D!
