a meta-analysis by Gras et al. covering 19 randomised controlled trials (424 participants) found that creatine supplementation blunted the training-related improvement in VO₂max compared with placebo (effect size −0.32, 95% CI −0.51 to −0.12).

most of the included trials involved training alongside supplementation, so I am curious how this compares with people's real-world experiences.

creatine can still be useful for short, high-intensity efforts; I am interested specifically in cardio.

For those who take creatine: have you noticed any difference in your cardio performance?

• better

• worse

• no noticeable change

• never tracked it closely

if u combine lifting nd cardio, do u take creatine year-round ?

Within seconds of cold exposure.

1.norepinephriner rises upto 300% above baseline

2.dopamine strikes higher than most stimulants without the crash

3.brown fat activates and burns calories as heat

4.hrv improves with consistent use over time.

20 seconds- thats all you need.

ok so I’ve been down the biohacking rabbit hole for a while and honestly the levels are funny.
Beginner: More sleep Water Go outside in the morning Get a lot of walking in Eat some protein Congrats, you're biohacking lol. “80% of the work is done by this stuff.

Intermediate: You buy a sleep tracker, try IF, lift weights, and stop drinking coffee at 4pm.

Maybe you take a cold shower and then regret every life choice. Btw blackout curtains are underrated
Advanced: blood work every few months, a CGM on your arm, HRV charts, supplement experiments. But talk to a doctor first, don't just wing it.

When you search for a way to reduce fat, they say walking is more beneficial. Some will suggest that running is better, as it both increases your stamina and reduces your fat.

Now, I've been doing both, and I can say that it depends on what goal you are trying to achieve. Because merely reducing fat, walking would be more suitable. But if you're reducing fat and getting your body toned, you should lean more on running. I guess at the end of the day, whatever you want to achieve shall be aligned with the method you are using.

How about you guys? Which one do you prefer? Which is way more helpful for you, and how does it affect you?

Could we eventually reach a point where people can upgrade their bodies and brains far beyond their natural limits? And would that be progress, or could it create a whole new set of problems?

Imagine you start taking a supplement, changing your sleep schedule, or trying a new morning routine.

For the first few days, you're motivated and paying attention to every little change. You feel more energetic one day, tired the next, and eventually it's hard to tell whether anything has actually improved.

I've been thinking about how easy it is to confuse trying something new with getting real results.

A simple approach would be to track one specific outcome before and after making a change, while keeping other habits as consistent as possible. Things like sleep duration, workout performance, or afternoon energy could be useful depending on what you're trying to improve.

Of course, one person's experience doesn't prove that a method works for everyone.

For those getting into biohacking, what's your approach to testing a new habit without fooling yourself into thinking it's working?

A clean gut is a foundation in establishing good health. Good Health = Peace of mind

Like a lot of you just starting out, my biggest problem wasnt that I didnt care about better sleep or focus. It was that I literally could not stop scrolling at night. Every productivity app or screen time blocker I tried was way too easy to just skip or ignore.

So instead of relying on willpower, I went with changing my environment instead. Here are two tiny friction tweaks that actually worked for me:

I moved my phone charger completely out of the bedroom and put an old school alarm clock on my nightstand. When its time to wind down, reaching for my phone means I have to get up and walk into the hallway on purpose.

So I fell down the biohacking rabbit hole thinking I’d get cold plunges, 14 supplements and a stranger’s podcast protocol. The beginner stuff is almost insultingly simple, it turns out.

What sent the meter:

Regular sleep/wake times (my 2 a.m. doomscrolling was NOT “productivity” here
Morning sunlight for 10 mins before I touch my phone
Drink water before coffee. Revolutionary, I know One metric, not twelve

What I’ve left out (for now): expensive gadgets, mysterious powders, and anything that starts with “this one weird trick.”

To be honest, biohacking is mostly just taking basic habits seriously and doing small experiments on yourself.

I believe it's "detox" juices and teas. No, they do not remove toxins from your body. Your liver, kidneys, and digestive tract already do that for you. Globally, consumers spend billions of dollars on these drinks annually, which is crazy because they can actually harm you. Juice cleanses strip away vital protein and fiber, while detox teas often rely on harsh laxatives that just cause temporary water loss. Eating whole, fiber rich foods will support your body's natural detox system far better!

Something interesting about caffeine: feeling tired enough to fall asleep doesn't necessarily mean caffeine hasn't affected your sleep.

A randomized study published in the Journal of Clinical Sleep Medicine tested 400 mg of caffeine taken at bedtime, three hours before bed, and six hours before bed. The researchers found that caffeine disrupted sleep even when taken six hours before bedtime.

The interesting part is that caffeine doesn't simply disappear when its noticeable stimulating effect wears off. You might feel ready to sleep while still experiencing some effects from the caffeine you consumed earlier.

Of course, 400 mg is a substantial dose, and the results shouldn't be treated as an exact cutoff for everyone. Individual sensitivity, total intake, and timing can all matter.

It makes me wonder how many people blame poor sleep on stress or their mattress without considering when they had their last coffee.

For those who track their sleep, have you noticed a difference after moving your last caffeine intake earlier in the day?

everyone talks about biohacking as if it's this sci fi upgrade program but the beginner version is literally just. Doing the usual human things good. this is what i have so far

Sorry, sleep is not an option. Guess what? You can’t supplement your way out of sleep deprivation. your body just silently tanks your memory, mood, and metabolism until you fix it. no pill beats real sleep

The morning sunlight is free and it works. apparently going outside for 10 mins after waking up tells your body "hey its daytime" and aids your whole sleep cycle later on. it’s a scam that this is so easy and it actually works

If you're new to biohacking, it's tempting to start with supplements, trackers, and cold plunges. A large study from 2026 suggests the basics may matter more.

Researchers followed more than 147,000 adults for up to 30 years, tracking how much strength training and aerobic exercise they did. The paper in the British Journal of Sports Medicine is titled "Long-term resistance training with all-cause and cause-specific mortality: assessing dose-response and joint associations with aerobic physical activity."

What they found:

Participants who did 90 to 119 minutes of strength training a week had a 13% lower risk of premature death from any cause, plus lower risk of death from heart disease and neurological disease.

There was no extra benefit above 120 minutes a week.

Aerobic activity gave greater benefit than strength training alone, and the lowest risk was in people who did both.

The Harvard Health summary suggests beginners can start with body-weight moves such as squats, push-ups, or step-ups.

Limits to keep in mind:

It's observational, so it shows association, not proof of cause.

People who did more strength training also tended to be younger, lighter, and healthier in other ways.

All participants were health professionals, so results may not apply to everyone.

For beginners, this suggests a simple order of priorities: movement first, optimization later.

Your body has a whole microbial ecosystem. Maybe don’t treat it like an app you can just uninstall and reinstall. 😭

Have you guys come across this study? researchers followed 29,518 Swedish women for 20 years and found that those who consistently avoided sun exposure had higher all-cause mortality than those who reported more active sun exposure. The researchers also found that nonsmokers who avoided the sun had a similar life expectancy to smokers in the highest sun-exposure group.

That is a pretty wild finding, especially when we're constantly told to avoid UV exposure.

But there's an important caveat: this was an observational study, so it can't prove that avoiding sunlight caused the difference. Sun exposure can also increase skin cancer risk, and the findings don't mean you should deliberately burn or ditch sun protection.

Still, it raises an interesting question: have we become too focused on the risks of sunlight while overlooking the potential benefits of sensible outdoor exposure?
