If you’ve ever been told, “Your thyroid labs are normal,” but still feel tired, foggy, or struggle with stubborn weight gain—you’re not imagining things. Many people live with undiagnosed or undertreated thyroid dysfunction because conventional testing doesn’t tell the full story. 

What Your Thyroid Actually Does (And Why It’s So Important)

The thyroid is a small, butterfly-shaped gland at the base of your neck, but don’t let its size fool you. It plays a critical role in regulating:

• Metabolism
• Energy levels
• Mood and mental clarity
• Body temperature
• Menstrual cycles and fertility
• Skin and hair health

When thyroid function is even slightly off, it can ripple across your entire system, affecting how you feel day to day.

Why TSH Alone Doesn’t Cut It

Most traditional doctors will only check TSH (thyroid-stimulating hormone) when screening for thyroid issues. But TSH is just one piece of a much bigger puzzle.

To truly understand what’s going on with your thyroid, we also look at:

• Free T3 – the active thyroid hormone your cells actually use
• Free T4 – the hormone your thyroid produces before it’s converted to T3
• Reverse T3 – a “brake” on thyroid function that can block Free T3 from doing its job
• Thyroid antibodies – markers that may indicate autoimmune thyroid disease, like Hashimoto’s

Here’s the problem: you can have a “normal” TSH and still have low Free T3 or high Reverse T3—leaving you symptomatic and frustrated.

The Problem with “Normal” Reference Ranges

Another major issue? Lab reference ranges are based on population averages, not optimal health. So even if your levels are technically within range, they might not be ideal for you. We’ve seen countless patients improve dramatically when their thyroid is supported into optimal—not just normal—levels.

Common Symptoms of Suboptimal Thyroid Function

• Fatigue or low energy
• Brain fog or memory issues
• Anxiety or depression
• Thinning hair or hair loss
• Dry skin and brittle nails
• Constipation or bloating
• Weight gain or difficulty losing weight
• Irregular or heavy periods
• Feeling cold all the time

These symptoms are often dismissed as “just stress” or “getting older”—but they’re red flags that deserve attention.

The Role of Nutrient Deficiencies

Even if your thyroid hormones are present, they need the right raw materials to work effectively. Key nutrients that support thyroid function include:

• Selenium – helps convert T4 to T3
• Zinc and iron – essential for hormone production and receptor sensitivity
• Vitamin D – supports immune and thyroid health
• Iodine – required for thyroid hormone synthesis, but more isn’t always better

Gut health also plays a major role. If you’re not absorbing nutrients properly, even the best diet or supplements won’t make a difference. That’s why we take a whole-body approach to healing.
