Ben Greenfield’s Weekly Roundup: March 14

📢 This Week in Health & Performance: What the Latest Research Says 🚀

Fasted Exercise & Metabolism: A meta-analysis of 28 randomized controlled trials found that fasted exercise led to greater post-exercise increases in blood glucose and insulin, along with a larger drop in free fatty acids—likely because the body is mobilizing its own energy stores (read the study here).

🍞 Why Sourdough Resists Mold: Sourdough bread naturally breaks down linoleic acid into antifungal compounds, helping it resist mold longer than conventional bread—just another reason to love this ancient fermentation process (read more here).

🌿 CBD & Sleep: The Dosage Dilemma: A new study claims cannabinoids don’t help with sleep, but here’s the catch—it only used a tiny 10mg dose of CBD. For real sleep support, higher doses (like 100mg) may be more effective (check it out here).

📌 Key Takeaway: From fasted workouts to ancient bread hacks and the truth about CBD dosing, this week’s research offers fresh insights to upgrade your health game.

Product Of The Week

::: Upgrade Your Oral Health With 15% Off SuperTeeth 🦷 :::

You brush. You floss. Maybe you even use fancy, expensive mouthwash. But here’s the harsh truth… most oral care routines completely ignore the root cause of cavities, gum disease, and bad breath.

Taking great care of your teeth and gums all comes down to your oral microbiome.

See, your mouth is teeming with bacteria—some good, some bad. When the bad guys take over, you’re stuck with cavities, inflamed gums, and chronic bad breath. Even worse? The bacteria in your mouth don’t just stay there. They can travel to your gut, your cardiovascular system, your nervous system, and basically, your entire body.superteeth wkru

That’s why I’m a fan of SuperTeeth, the first oral care brand that uses science-backed probiotics specifically designed to restore balance to your mouth’s microbiome. These probiotics don’t just help heal your gums, teeth, and breath—they support whole-body health, too.

Here’s why I recommend SuperTeeth:

✅ Root cause healing: Probiotics that support the health of your entire mouth, tackling cavities, gum disease, and bad breath at the source.

✅ Whole-body benefits: Because your mouth is the gateway to your body, improving oral health means supporting your gut, brain, and cardiovascular system too.

✅ Clean ingredients Only: No fluoride, no SLS, no toxic fillers or dyes—just science-backed, non-toxic, family-safe formulas.

✅ Clinically proven: Every product is grounded in clinical research, delivering real results you can feel, smell, and taste.

✅ Full transparency: Full ingredient lists are right on the product pages. No weird stuff, no secrets.

Because I’m all about clean, effective, and simple biohacks, I consider this an easy win for better health without even really needing to change your routine. Simply swap out your current oral care products for SuperTeeth, and let the probiotics do the heavy lifting.
