The inflammation your labs called normal.
Optimal hs-CRP is under 1.0 mg/L. Most labs flag a result only above 3.0. The range in between is where chronic low-grade inflammation quietly sits, and it is associated with cognitive decline.
Chronic and quiet, not acute and obvious.
Standard CRP is designed to spot acute inflammation, like an active infection or a recent injury. hs-CRP is designed to spot chronic low-grade inflammation, the kind that does not feel like anything but is associated with long-term risk for cardiovascular disease, type 2 diabetes, and cognitive decline. For brain health, the chronic low-grade version is the one we care about.
People with higher long-term hs-CRP have higher rates of cognitive decline, faster brain atrophy on imaging, and elevated risk of Alzheimer's disease. Inflammation does not directly cause Alzheimer's, but it appears to be one of the upstream conditions that lets the underlying pathology progress more quickly.

Three ways in, one page. Pick the one that sounds like you.
A single value is informative. A panel is actionable.
A single hs-CRP value is informative but more useful with other biomarkers to understand the whole picture. The picture you assemble tells you whether the inflammation is metabolic, vascular, nutrient-driven, or something else.
See everything we test ↗Do not stop at the number.
Because hs-CRP can be influenced by several systems at once, the right next step is to identify the most likely driver in your case.
hs-CRP detects very low levels of CRP that the standard test cannot. If you have not had a high-sensitivity version measured in the past year, it is worth checking.
Homocysteine, ApoB and Lp(a), HbA1c and fasting insulin, and ferritin. Together they tell you whether the inflammation is metabolic, vascular, nutrient-driven, or something else.
If hs-CRP is elevated alongside high HbA1c, the first priority may be blood sugar regulation. If it is elevated alongside high homocysteine, the starting point may be methylated B-complex and a closer look at folate, B12 and B6 intake.
"In range" is not the same as optimal.
Most standard labs flag a result only when it crosses 3.0 mg/L or higher. The 1.0 to 3.0 range is where a meaningful number of clients are quietly running elevated. Their primary care has waved it off as "in range." However, for brain health purposes, this is not optimal.

Standard CRP and hs-CRP are not the same measurement. One is built to catch an active infection; the other is built to catch what does not feel like anything.
hs-CRP detects the low-level chronic inflammation the standard test misses. BetterBrain reads it alongside homocysteine, ApoB and Lp(a), HbA1c and fasting insulin, and ferritin, with a cognitive baseline, health history and expert review.
Information is one input. The plan is the product.
BetterBrain does not hand you a number and wish you luck. Every result is read inside a system built to explain what it means for you, and where you can take meaningful action.
There is more to brain health than one marker.
The 2024 Lancet Commission estimates that addressing 14 modifiable risk factors across life could prevent or delay around 45% of dementia cases at the population level. The useful question is where your own margin lies.
Review the evidence ↗Clear answers, without false certainty.
CRP, or C-reactive protein, is made by your liver in response to inflammation anywhere in your body. The "hs" stands for high-sensitivity, which means the test can detect very low levels of CRP that the standard CRP test cannot.
One of the most useful brain-health markers, and one of the most commonly missed.
If you have not had a high-sensitivity CRP measured in the past year, it is worth checking. BetterBrain Blueprint covers hs-CRP alongside 50+ other markers, with coach interpretation, and starts at $89 with insurance.
