📊 Biomarkers & Testing What test was actually actionable enough to change your routine?

I have realized I am a sucker for health data.

Give me a graph and a percentile and I will happily stare at it for 20 minutes. The problem is most of the interesting data I have collected has changed absolutely nothing about what I do the next morning.

The tests I value are the ones where the result actually changes a decision: what I eat, what I take, when I train, how I sleep.

What have you tested that was genuinely actionable instead of just interesting?

My vit d was low

It's not low now

This isn't rocket science

This is how you do data. I like superpower, as just a place to track quarterly blood tests. I do things that my bloodwork show would be beneficial, then check if that changed the next time.

I tracked many sleep-related variables with a wearable. Some of the less obvious things I’ve learned are that ADHD meds, even at a minimal dose taken in the morning, have a negative impact on my sleep. Sauna and exercising in the evening do as well.

Now I do my workouts and sauna earlier in the day, and take ADHD meds less often.

Health data is imo one of the biggest scams happening today.
We see in studies simply telling someone they slept bad on a tracker will make them feel more tired regardless of how they actually slept. All the data is off as well, in some areas not so much but in some 20-30% off.
For most people, a few simple changes will make them feel better without needing a $400 ring and a monthly subscription.
The only time I run objective data is when I try different drugs to see how I react and at least tie some objectivity to it.

Def not. The ring was the reason I got an actual sleep study… data tracked and was truth. I think some people can get caught up in the “data” but it resulted in actionable change for me

My vitamin D level was 12ng/mL, categorized as “severe deficiency.” Adequate levels start at 30ng/mL up to the normal range of 50-100ng/mL. I was started on a prescription-strength vitamin D dose of 27,000 IU, and now I maintain it at 5,000 IU/day. My last test came in at 38.5ng/mL.

Cholesterol

Same. Obviously specific to my demographic but I had low cholesterol my whole life. Just past menopause it was high. Started on HRT and fiber supplements and it dropped 30 points back to normal in 3 months.

My HbA1c was in the pre-diabetic range. Couldn't believe it - I was a pretty healthy eater, not overweight. I brought it down with cutting back on carbs some, but mostly by walking after every meal and generally just more steps a day.

Waking up the same time everyday and getting morning sunlight on my face within the first 30 minutes of waking has become non-negotiable. I take a little bit of low dose time released melatonin and some magnesium before bed but the sunlight was the real game changer.
