Supplements for Brain Health—What Matters and What Doesn’t
By Dr. Mike
Every week, a patient walks into my office with a new brain health supplement—some powder, pill, or oil they found online. And my answer is usually the same:
🧠 Supplements are 5th-order tools.
If your sleep is broken, your blood pressure is high, your insulin is a mess, and you don’t move—you’re trying to bail out the Titanic with a teaspoon.
That said, if you’re already doing the big things right, there are a few supplements that may give you a modest edge—especially if you’re correcting a deficiency.
Let’s break down what’s worth considering—and what’s just hype.
🥇 Top 3 Supplements That Might Matter (If You’re Deficient)
- Omega-3s (EPA & DHA)
- May support brain function, especially if your levels are low
- Ideal range: 8–10% on Omega-3 Index test
- Many RCTs are flawed because they give everyone the same dose without measuring whether levels change
- Good for the heart, possibly good for the brain—especially in low seafood consumers
🧪 Ask us about getting your Omega-3 levels tested.
- Vitamin D
- May help cognitive health if you’re deficient
- Most studies use random doses (e.g., 2,000 IU) instead of targeting optimal blood levels (60–70 ng/mL)
- Absorption varies a lot—what works for one person might not for another
☀️ If you’re indoors a lot or live in the Northeast, this one’s worth checking.
- B Vitamins (B6, B12, Folate)
- May help reduce homocysteine, a marker linked to brain atrophy
- Most useful in people with low levels or elevated homocysteine
- Often found in quality multivitamins or methylated B-complex formulas
These aren’t magic—but if you’re low, they can make a difference.
⚠️ Supplements That May Help—But Only If You’ve Done Everything Else Right
These fall into the “marginal gains” category. They’re not essential—but may provide a small edge for high-risk or optimization-focused individuals:
🔸 Creatine
- May improve short-term memory and fluid intelligence
- Especially helpful for vegetarians or older adults
- Supports ATP production in brain and muscle
- Generally safe and well-tolerated
🔸 Curcumin (Theracurmin, high bioavailability)
- Anti-inflammatory compound from turmeric
- Some modest evidence for cognitive support
- Likely more useful in an anti-inflammatory lifestyle than as a standalone fix
🔸 Magnesium L-Threonate (Magtein)
- Designed to increase magnesium in the brain
- Sparse human data but promising for sleep and cognitive support
- Expensive and speculative—but probably harmless
🧠 The Titanic Analogy
“Taking omega-3s while ignoring your blood sugar is like applying sunscreen on a sinking ship.”
Supplements aren’t the enemy—but they’re not the answer either.
They work only when the foundation is solid:
- Blood pressure optimized
- LDL cholesterol in range
- Glucose and insulin controlled
- Consistent sleep
- Regular exercise
- Clean nutrition
If you’re missing those, start there.
