The most important guides for fast decisions
These articles answer questions where users are often close to taking action, measuring, buying supplements or needing Premium interpretation.
Combining supplements
Check duplicates, values, food-first and safety context.
SupplementsToo many supplements?
See whether your stack is too large, unclear or lacks re-checks.
LabsWhich blood tests to measure?
Baseline values for metabolism, lipids, inflammation, iron, B12 and vitamin D.
MetabolismImprove HbA1c
Connect nutrition, movement, sleep and re-checks.
HeartApoB vs LDL
Understand particles, lipids, triglycerides and cardiovascular context.
MeasurementsMeasure blood pressure for 7 days
Turn single readings into a more useful trend.
WearablesUse wearables correctly
Interpret HRV, resting HR, VO2max, sleep and steps as trends.
RecoveryLow HRV
Interpret stress, sleep, training, alcohol or illness better.
Topic clusters
Start with the article cluster that matches your question
LongLifeScan articles are not meant as random blog posts, but as structured paths: understand blood markers, evaluate supplements, improve measurements and turn the result into useful next steps.
Understand blood markers
For HbA1c, ApoB, LDL-C, triglycerides, hs-CRP, ferritin, TSH and useful lab questions.
Evaluate supplements responsibly
For vitamin D, omega-3, magnesium, creatine, iron, B12 and the question of when less is more.
Measure, track and use wearables
For blood pressure, wearables, HRV, resting heart rate, sleep, steps and better measurement quality.
Nutrition, movement and plans
For practical levers after blood markers: nutrition, movement, protein, fiber and next steps.

Low HRV: stress, sleep, training or illness?
Low HRV is not a diagnosis. Personal trend, sleep, resting heart rate, training, alcohol, stress, illness and recovery matter.
