Your Thyroid Labs Are “Within Range.”
So Why Do You Still Feel Miserable?
You Deserve Better Answers.
If you’ve been told your thyroid labs are within range, but you still feel tired, foggy, frustrated, or not like yourself, you’re not imagining things. And you’re far from the only person this has happened to.
Standard thyroid testing often stops too early. Many patients are told they’re “fine” based on limited lab work, even while symptoms continue — or get worse.
At Renewed Vitality, we specialize in helping people who know something isn’t right, even when they’ve been told nothing is wrong.
We take a more complete approach to thyroid health, using comprehensive testing and individualized care to uncover what basic labs often miss, so you can finally understand what’s going on and what to do next.

Is This You?
If your doctor has told you these symptoms “aren’t thyroid-related,” this may sound familiar:
-
You’re exhausted or low on energy most days
-
You’ve gained weight or struggle to lose it
-
You feel cold, foggy, or mentally sluggish
-
You’re already on thyroid medication, but still don’t feel well
-
You’ve been told your labs are “within range,” but your symptoms say otherwise
Many of our patients come to us after years of being told nothing is wrong, even though they know, deep down, that something is.
Being dismissed like that is exhausting. It’s also unnecessary.
You deserve care that takes your symptoms seriously.
A More Complete Approach to Thyroid Care
Most thyroid evaluations focus on a single number — usually TSH — and stop there.
We don’t.
At Renewed Vitality, we look beyond basic labs to understand how your thyroid hormones are produced, converted, and actually used by your body, and how that aligns with how you feel day to day.
Our approach includes:
-
Comprehensive thyroid testing, not just TSH
-
Evaluation of how your body converts and utilizes thyroid hormones
-
Symptoms reviewed alongside labs — not ignored
-
Personalized treatment plans, not one-size-fits-all protocols
We see patients like you every day, people who have tried to get answers elsewhere and were left frustrated.
Our goal is to replace uncertainty with clarity and give you a plan you can finally trust.
Thyroid Conditions We Commonly Evaluate
- Hypothyroidism
- Hashimoto’s disease
- Hyperthyroidism and Graves’ disease
- Thyroid-related fatigue, weight gain, and cognitive symptoms
These conditions often show up as fatigue, weight gain, brain fog, mood changes, and feeling unlike yourself.
Every patient receives an individualized evaluation to determine the most appropriate next steps.
Because no two thyroid cases are exactly the same.

“I was told I didn’t have a thyroid issue and wouldn’t be treated.”
“I have had thyroid issues since I was 23 years old. I have been to doctors who cared and treated me but then moved on to other practices and were replaced by doctors who told me I didn’t have a thyroid issue and wouldn’t treat me.
“When my health got worse, I started doing my own extensive research and went on a search to find a doctor who cared and was willing to listen and was going to be there when I needed him. Dr. Spurlock is the best and most knowledgeable doctor I have ever found!
“If you want a doctor who is willing to think outside the box, investigate and study solutions that can improve your health and cares about you then go to Dr. Spurlock. I have referred many friends and family members to him.” – D.B.
