Hey fitness nerds!

Thank you all {{active_subscriber_count}} of you!

You've probably seen NMN bottles flying off the shelves, promised as the fountain of youth in capsule form. Big names swear by it, podcasts won't shut up about it, and the price tags keep climbing.

But the science underneath all that hype tells a much messier story than the marketing wants you to believe. What we found this week might change how you spend your supplement budget.

Read below!

IN LESS THAN 10 MINUTES WE WILL COVER:

A 60 year old biotech billionaire pops a £90 pill every morning and tells the world it makes him 18 again.

The pill is NMN. The science says he is mostly wrong.

NAD+ is real. The decline is real. The "miracle" is the part the supplement industry made up.

By the time you hit 50, your NAD+ levels have crashed by roughly 50%. NAD+ runs your mitochondria, repairs your DNA, and keeps your cells producing energy. Without it, you fall apart. With it, you function.

So when somebody found a pill that boosts NAD+ in your blood, the wellness internet lost its mind.

Then the human results started rolling in. They told a very different story.

NAD+ is not marketing. It is the coenzyme your body uses every second of every day to turn food into the energy that runs your brain, your muscles, and your immune system.

Your levels drop by half between 20 and 60. That decline tracks almost perfectly with the slow grind of fatigue, slower recovery, and the muscle loss most people accept as "just getting older".

NMN is a precursor your body converts into NAD+. Take it, and your blood NAD+ doubles within 8 to 12 weeks.

That part is settled science. The rest is not.

Here is what is actually happening. NMN reliably raises NAD+ in your blood. Tolerability is excellent. Side effects are basically nothing.

Then somebody measures whether you actually feel younger. Whether you live longer. Whether your body works better.

The results are flat. Walking speed maintained instead of declining. Sleep nudged up 10 to 20%. Modest tweaks to muscle parameters. No reversal of anything.

The mouse data that kicked off this craze showed rodents living 10 to 20% longer on NMN, but no human has ever been measured gaining a single extra day from it.

Most human trials run fewer than 60 people over a few months. Nobody has shown NMN extending human life. Full stop.

You are paying premium prices for biological activity that has not been shown to produce a single concrete anti ageing outcome in a real person.

Here is the part the marketing pages will not tell you. There are two main NAD+ precursors. NMN, and a cousin called NR.

At equal doses, NR raises blood NAD+ 2.3 times more than NMN. Same dose. Better result.

If you have been buying NMN because some podcaster told you to, you may have been buying the second best version of an unproven thing.

Even more interesting, that NAD+ boost has been linked to changes in your gut bacteria producing short chain fatty acids. Translation. The "magic" of these supplements may not be the NAD+ itself. It may be a side effect on your gut microbes.

Which is the kind of thing fibre, fermented food, and a good night of sleep do for free.

While people are spending £80 a month chasing a pill, the cheapest NAD+ boosters on earth are sitting in the corner of every gym and kitchen.

Hard exercise raises NAD+ by 20 to 50%. Especially intervals where you actually feel like you might die. Fasting and calorie restriction do the same. So does sleep.

These are not new findings. They have been replicated for decades. They cost nothing.

If you have not nailed sleep, training, and food, no supplement is going to save you. NMN cannot rescue a bad lifestyle. The pills nudge NAD+ by margins similar to sprints and skipped meals, and the sprints come with abs.

Skip the influencer hype. Here is the actual play.

If you are under 40 and healthy, do not buy NMN. Your body still makes plenty of NAD+. Your money is better spent on a barbell.

If you are over 50 and curious, buy NR not NMN. Look for third party tested products with a USP or NSF stamp. Skip anything sold as IV NAD+. There is no real evidence behind those drips and the bill runs into hundreds.

Dose 300 to 1,000 mg per day. Run it for 8 to 12 weeks. If you feel nothing, stop.

Stack it with the free stuff. Three hard interval sessions a week. 14 to 16 hour overnight fasts a few days a week. 7 hours of actual sleep. These three habits will move your NAD+ further than any pill on the market.

NMN is not snake oil. It is real biology with weak human results, and you are watching the supplement industry sell hope at a 90% margin while the answer to most of what they promise is already in your training shoes.

Save your £80. Lift something heavy. Go to bed.

You have been lied to about protein. The rules you follow were written for sedentary office workers, not humans who actually train.

Most chicken salad is mayo soup with a few sad shreds of meat hiding inside. This one flips the script.

Greek yogurt does the heavy lifting, so every bite hits 35g of protein without the grease coma after.
