Get These 3 Numbers In Optimal Range First, and Keep Them There

Vitamin D: 40–60

Omega-3 Index: 8–12%

Homocysteine: <10

Dr. Gills highlights these critical lab levels because they directly impact your energy, focus, and long-term vitality.

The 3 Biomarkers That Tell the Truth About Your Health

When you get your blood drawn, your lab report will list dozens of numbers.

But not all of them matter equally. Dr. Gills recommends focusing on 3 key biomarkersOmega-3 Index, Vitamin D, and Homocysteine — because research shows they have the biggest impact on your heart, brain, and long-term health.

These are numbers you can ask your physician to test for, or use at-home services designed to measure them. Either way, it’s critical to know where you stand.

Testing these 3 critical levels helps you:

The 3 Biomarkers That Matter Most in Your Labs

On your next lab visit, look for these 3 numbers on your results. They tell you if you’re just “in range” or if you’re truly at a "research optimal" level for protection and performance.

Why OMEGA-3 Matters

Omega-3s fuel your heart, brain, and cells. Staying in the research-optimal range (8–12%) helps reduce inflammation, improve cognitive performance, and protect against heart disease.*

What Happens When You’re Out of Range

Omega-3s fuel your heart, brain, and cells. Staying in the research-optimal range (8–12%) helps reduce inflammation, improve cognitive performance, and protect against heart disease.*

ResEARCH OPTIMAL:

30–60 ng/mL*

Why VITAMIN D Matters

Vitamin D acts like your body’s shield — supporting bone strength, immunity, mood, and long-term health. The research-optimal range (30–60 ng/mL) is where the strongest protection is found.*

What Happens When You’re Out of Range

Too little Vitamin D can leave you fatigued, vulnerable to infections, and at higher risk for bone loss and chronic disease. Most people are low without realizing it, which is why testing is critical.*

ResEARCH OPTIMAL:

5–7 µmol/L*

Why Homocysteine Matters

Homocysteine is one of the most powerful markers for cardiovascular and brain health. Keeping it in the research-optimal range (5–7 µmol/L) protects your arteries, heart, and cognitive function.*

What Happens When You’re Out of Range

High homocysteine can damage blood vessels, increase plaque buildup, and raise risk for heart disease and cognitive decline.*

Take the Next Step:

Test Your Labs

Your numbers only matter if you measure them. At your next lab visit, ask your doctor (or testing provider) to include these 3 critical biomarkers: Omega-3 Index, Vitamin D, and Homocysteine.

How Often Should You Test?

Annually — at a minimum, include these markers in your yearly physical.

Every 6 months — if you’re adjusting diet or supplements and want to track progress faster.

What To Do Next

1

Schedule your next appointment with your physician, or use an at-home lab testing service.

2

Confirm that these 3 biomarkers are included on your lab order.

3

When your results come back, compare them to the research-optimal ranges — not just the “normal” ones.
