It’s been a while since we’ve posted the **Dirty Dozen**, and as we head into a new season, we thought it was a good time for a reminder. 🍎🍓🥬

Each year, the Environmental Working Group (EWG) reviews pesticide residue data and identifies the fruits and vegetables with the highest residues.

If you’re wondering where it may be most worthwhile to spend the extra money on organic produce, the Dirty Dozen can be a helpful place to start.

One important reminder: **this list is not a reason to avoid fruits and vegetables.** If organic isn’t available or affordable, continue eating conventional produce and wash it well. The goal is simply to reduce pesticide exposure when and where it makes sense for you.

Cold and flu season is coming… is your medicine cabinet ready? 🤧🌿

We like to have these things on hand before someone in the house starts feeling sick.

From elderberry and essential oils to saline rinses, castor oil, DGL, and a few of our favorite supplements, these are 10 tools we reach for throughout cold and flu season.

The goal isn’t to replace medical care when you need it. It’s to be prepared with simple tools that can support immune function, respiratory health, inflammation, digestion, and recovery.

📌 SAVE THIS POST so you can come back to the list when you’re stocking your own winter medicine cabinet.

Want to know why we use each one and exactly how we use it? I break down all 10 in the full blog, DM for the link.

Have you ever been told, “Your labs are normal,” even though you still don’t feel well?

Maybe you’re exhausted, struggling with brain fog, gaining weight, having digestive problems, or simply know that something feels off.

A “normal” lab result means your value falls within that laboratory’s established reference range. Which for many lab tests, is essentially the range where about 95% of a selected healthy reference population falls. That does not mean where your numbers should fall. In functional medicine we look for your numbers compared to the "optimal" range, where they should be.

We may also look for patterns across thyroid function, nutrient status, iron, blood sugar and insulin, inflammation, hormones, and more.

The “optimal” ranges in this graphic represent examples of narrower targets sometimes used by functional medicine practitioners; they are not universally established medical reference ranges and shouldn’t be used to diagnose or treat yourself.

At Premier IFM, we believe the question shouldn’t only be “Is this result in range?” It should also be “Does the entire clinical picture help explain how this patient feels?”

Yesterday we shared the story of a patient who came to Dr. Craig with Parkinson’s-like symptoms and a long history of digestive problems.

When Dr. Craig began looking beyond the neurological symptoms and investigating what might be affecting multiple systems in the body, testing uncovered something unexpected:

**The patient had very high levels of bismuth in his system.**

That discovery raised the next question: Where was all of that bismuth coming from, and what role, if any, could it be playing in his symptoms?

This was an important clue, but it wasn’t the end of the investigation.

Watch the clip to hear what Dr. Craig found. The complete case study is also available on our website and YouTube channel.

A patient came to Dr. Craig after developing symptoms that had been described as Parkinson’s-like.

But during his initial visit, Dr. Craig didn’t just focus on the neurological symptoms. He went back through the patient’s entire health history—and learned that he had struggled with significant digestive problems for years.

That combination caught his attention.

When symptoms are occurring in seemingly unrelated systems, the gut and the nervous system, it raises an important question: **Are these separate problems, or could there be something affecting the body more broadly?**

That question led Dr. Craig to look deeper.

This clip shares part of the case, but the full patient story—and what they ultimately discovered—is available on the Premier IFM website and our YouTube channel.

**Berberine + metformin: should you take them together?**

It’s an increasingly common question, especially as berberine becomes more popular for blood sugar and metabolic health.

Research suggests that berberine alone may help improve fasting blood glucose, post-meal glucose, HbA1c, triglycerides, and cholesterol. Some studies have found its blood-sugar effects to be comparable to metformin.

Combining berberine with metformin may provide additional glucose-lowering benefits for some people, but that doesn’t automatically make the combination better, and it certainly doesn’t make it a simple weight-loss strategy.

Because the two can have overlapping metabolic effects, combining them may also increase the risk of low blood sugar, gastrointestinal symptoms, and medication interactions.

At Premier IFM, the goal isn’t simply to add more supplements or medications. We look at what is actually driving metabolic dysfunction and build a plan around the individual.

**Berberine, metformin, or both? The right answer depends on your metabolic picture.**

Always speak with your healthcare provider before combining berberine with prescription medication.

Okay, we’ve been talking about our FMD, so we figured we should probably explain what we were actually doing! 😂

Dr. Craig and I filmed this on **day 4 of our 5-day Fasting Mimicking Diet**—so keep in mind we were four days into very little food when we decided it was a good time to explain it. 🤪

Here’s what an FMD is, why we decided to try it, and a little about our experience.

We made it through all 5 days! 🙌 Who wants to get in on the fun for our next cycle?

08/18/2026

I went to Walmart for ONE specific thing…and this is what happened. - Watch Dr. Craig find out what I got.

For context, Dr. Craig and I were on day 4 of a 5-day fast, so our brains may not have been operating at 100%. 🤪 But hey—we found some pretty fun stuff!

Don’t mind us, we’re just starving. 😂 Stay tuned for our FMD video to see why!

🥛 Got heartburn? Reach for milk?

Here's what's actually happening: milk temporarily neutralizes stomach acid — which is why it feels soothing in the moment. But the fat and protein in milk then signal your stomach to produce more acid. And whole milk relaxes the valve between your esophagus and stomach, making it easier for acid to come back up.

Temporary relief. Bigger problem an hour later.

The better options:
✅ Low-fat or skim milk — less rebound effect
✅ Almond milk — mildly alkaline, low fat
✅ Kefir or yogurt — probiotics actually help GERD
❌ Whole milk — worst offender

But here's the real question: why are you getting reflux in the first place?

Low Stomach Acid
H. Pylori
Food Sensitivities
Gut Dysbiosis
Hiatal Hernia
Stress & Cortisol

That's the functional medicine conversation worth having.

"Everything looks normal."

For many couples struggling to conceive, those words bring more frustration than relief.

The truth is, infertility is often a symptom of underlying imbalances rather than a condition with no explanation. While conventional fertility testing is incredibly valuable, it doesn't always evaluate factors like thyroid autoimmunity, insulin resistance, chronic inflammation, gut health, nutritional deficiencies, s***m DNA fragmentation, or environmental toxins.

In these slides, Dr. Craig explains why a more comprehensive evaluation may help uncover answers when standard testing hasn't.

If you've been told you have "unexplained infertility," this is worth reading.
