I started taking 3g of pharmaceutical grade fish oil about 1 year ago with 5000IUs vitamin D and 120mcg of K2 MK-7. I don’t “feel” anything but my Garmin is clear that my RHR and VO2max have greatly improved, and yet that’s on 5-6h sleep per night. I’m also definitely less sick.
Now question remains, which of those is responsible for this?
Here’s the thing, I don’t work out much, if at all other than cleaning the house and mowing the lawn. Not much has changed on the lifestyle side, overall.
I recently started doing the stepper and noticed the improvement compared to occasional physical activity that I inconsistently do from time to time (e.g. sports outside with the kids).
If you can find fresh oiled packed (refrigerated, typically not salted) white anchovies, a small handful of them feels similar to taking focus enhancing drugs. They are also delicious.
By contrast, tin packed/anythong not fresh has no effect for me.
Do you know anybody with one? I've never heard of WHOOP before. It looks cool, but $30/month for what seems like a fitbit is a bit much for me. I guess the difference is the WHOOP device is included in the subscription.
Id be interested to hear someone's experience with it vs a 'normal' fitness tracker.
I've been a fitness and gadget junkie for a long time.
I was gifted a WHOOP 6-month subscription in December 2020, and I used it from then until the end of that 6-month term. This was the 3.0 platform.
It was fine for the price - $0 - and provided me with HRV and a "sleep score", which is of interest to me and other athletes as one indicator of "fitness."
I did not - and will not - pay $360/year for WHOOP. I could actually buy a pretty nice state-of-the-art new real fitness tracker for less than that, and the features that were somewhat novel to WHOOP are now standard on other hardware platforms (Garmin, Polar, others). Note that with many Fitbits and clones, you get GPS built-in so you can leave your phone at home and do your thing.
It differed from other fitness trackers mostly by what it didn't have, and DC Rainmaker has exhaustive reviews up to and including the current 4.0 release.
In short, it's not a fitness tracker like a Fitbit Charge 4 or a Garmin Venu 2 Plus - I own both - because it doesn't track steps, has no GPS (you need to lug around your phone for that), and relies entirely on HR for what it tells you - all for a pretty heavy price tag. It also doesn't pair with 3rd party HR hardware (such as the usually more accurate EKG-based ones like a Garmin or TICKR chest strap) and relies on wrist optical sensors.
There are a number of metrics WHOOP reports, but they are simply rehashed versions of metrics developed by Andy Coggan and others some time ago.
TL;DR: WHOOP is overpriced and not feature-rich as a fitness/activity tracker. If you get one for free, try it out. You can easily get the same functionality and more for half the price of a yearly subscription.
Iron, but I typically have low iron. Takes a while to kick in.
Beta-alanine: I notice same day improvements in lung function
Vitamin D: but only after a couple weeks and only if I'm low.
Besides that I've found no correlation at all, but this is super anecdotal anyway.
Iron is really a touchy one to get right, as its easy to go overboard. Good thing you know you have low iron, but if you're not sure a blood test can illuminate if a problem is there - a good "talk to your doctor first" supp.
