Over the years, I’ve learned the hard way:
Doing the right thing the wrong way can still hurt you.
I almost made that mistake myself when I first started looking into magnesium supplementation.
I grabbed the first “magnesium” bottle I found at my local co-op—without realizing it wasn’t even the form my body could use.
And I’ve seen countless patients do something similar with flossing: overcomplicating it until it falls off their daily routine altogether.
These small, hidden mistakes quietly sabotage our health.
Luckily, they’re easy to fix once you know what to look for.
Mistake #1: Grabbing the wrong magnesium off the shelf
You already know magnesium is critical for your health.
But not all magnesium is the same.
Most people just grab the cheapest bottle—usually magnesium oxide—which is barely absorbed by your body.
Even if you’re using magnesium glycinate (a better form), you’re still missing out—because your body needs different types of magnesium for different jobs:
- Calming the nervous system
- Supporting deep sleep
- Strengthening bones and enamel
- Reducing systemic inflammation
That’s why I personally take this brand—it contains 7 different forms, not just one.
(And it’s third-party tested for purity—something a lot of other brands skip.)
When you get magnesium right, the effects ripple across your entire body:
- Sleep deeper
- Build stronger teeth
- Protect your heart and brain
- Lower your stress levels
Magnesium deficiency is already one of the most common—and invisible—nutrient deficiencies in the world.
Fixing it now can future-proof your health.
Mistake #2: Thinking fish oil covers all your omega needs
There is a newly discovered essential fatty acid—C15:0—that fish oil doesn’t give you.
C15:0 will help you age slower, repair your cells, and feel younger from the inside out. It’s crucial for cell membrane strength, mitochondrial energy production, and reducing cellular inflammation.
Modern diets (even “healthy” ones) are almost always missing it. Most fish oil supplements do not contain C15:0 — they are high in omega-3 fatty acids (EPA, DHA), but miss C15:0 entirely.
The Fix:
The highest natural food sources of C15:0 are full-fat milk, cheese, and butter.
I take this supplement daily because I would otherwise have to drink a lot of full-fat milk to get enough C15:0 daily.
The benefits:
- Stronger, more resilient cells
- Lower inflammation
- Healthier heart, brain, and metabolism
- Slower biological aging
Mistake #3: Overcomplicating flossing
The second mistake I see all the time?
Making flossing harder than it needs to be.
Patients invest in bulky water flossers that sit unused under the sink.
Or they wrestle with slippery string floss at the end of a long, exhausting day.
I used to recommend water flossers too—until I realized most people just stop using them.
Flossing needs to be dead simple to become a daily habit.
That’s why I’m a huge fan of flossing sticks like this one.
- It turns flossing into a one-handed, easy operation
- No finger pinching, no sink clutter, no excuses
- It’s efficient, clean, and easy to stay consistent with
Consistency is what matters for preventing:
- Gum disease
- Systemic inflammation
- Cardiovascular and brain risks linked to poor oral health
The systemic benefits are huge—but only if you make it sustainable.
The Bottom Line
It’s not enough to do the right things.
You have to do them the right way.
- Get magnesium from multiple, absorbable forms (like this brand, which I take every day)
- Floss easily and daily with a simple tool you’ll actually use (like this one, which I use daily)
- Take C15:0 to age slower and help your cells repair (I take this brand every day)
Sometimes it’s not about trying harder—it’s about getting consistent with a few things that truly matter.
I hope today’s email inspires you to make a few small tweaks—the kind that will pay off with massive health and vitality for years to come.
