Getting the Most Accurate Hormone Lab Results
When it comes to hormone testing, timing really matters — and so do your supplements.
As part of your hormone and mineral balancing program, we use your bloodwork to see how your hormones are responding to the support you’re giving your body. But even a few small things — like taking a vitamin the morning of your test — can change your numbers and make it look like your hormones are off when they’re actually fine.
Here’s how to make sure your results are clear, accurate, and helpful:
🚫 Skip Biotin for 3 Days
If you take a “hair, skin, and nails” supplement, it probably contains biotin.
Biotin is wonderful for beauty — but it can confuse the lab machines and make your hormone or thyroid results look too high or too low.
👉 Stop all biotin-containing supplements for 72 hours (3 full days) before your blood draw.
⏰ Get the Timing Right
Hormones rise and fall naturally through the day and your cycle, so we want to catch them at the right time.
If you still get a period: test around days 19–22 of your cycle (about a week before your period starts).
If you’re postmenopausal: test in the morning, and try to test around the same time for future labs too.
If you’re on thyroid medication: take it after your blood draw that day — not before.
If you’re using hormone creams or patches: skip them for 2 days before your test.
These simple timing shifts help the numbers reflect your body’s true balance.
💊 Be Careful With Other Supplements
Some vitamins and supplements can also change how your labs look — even though they’re good for you!
For example:
Vitamin C can make glucose look higher or lower.
Creatine can make it seem like your kidneys are stressed.
Calcium can affect bone scan results if taken right before.
So unless I’ve told you to keep taking something, it’s best to pause non-essential supplements for 2–3 days before your test.
🌿 Why It’s Worth It
Your labs are like a snapshot of your body’s communication system.
When we test at the right time and prepare properly, we get a clear picture — not a blurry one.
That means your program stays personalized, safe, and effective.
These steps might seem small, but they make a big difference in how we understand your hormones and guide your healing.
If you have any questions before your next lab draw — or you’re due for a retest (usually every 4–6 months) — just reach out. I’ll make sure you have all the right instructions before your appointment.
