For men 40+ · From William Bosch, founder of LongevityX

You’re doing the 80%. Here’s the one supplement worth adding.

After 40, most men notice energy gets harder to come by, even when they train, eat well and sleep. Part of the reason lives inside your cells: a helper molecule called NAD+, which human studies find at lower levels in older adults.^[6] LX NMN+ gives your body 1,000 mg of its direct building block, NMN, with TMG.*

Sound familiar?

You’re fit enough. Disciplined enough. And still hitting the wall?

You’re up before the house. You still lift, or you’re working your way back to it. You run the company, the team or the deal flow, and you eat better than most guys you know. And somewhere around mid-afternoon, you fade anyway. The meeting runs long, the coffee stops working, and by the time you get home there’s not much left for your family or the golf game you keep promising yourself.

Most men over 40 try the obvious fixes first: another coffee, more cardio, cutting carbs, a drawer full of supplements. A supplement stack isn’t a system, and borrowing energy from later in the day isn’t the same as making more of it.

Here’s the part almost nobody explains: energy is made, not willed. Every cell in your body turns food into usable energy with help from NAD+. And NAD+ is found at lower levels in older adults than in younger ones.^[6]

What you feel

The afternoon wall that coffee no longer fixes
Recovery that takes longer than it used to
Training like you used to, and not bouncing back like you used to
Less left in the tank for family at night

What’s going on underneath

NAD+ helps your mitochondria turn food into ATP, your cells’ energy currency
Human studies find lower NAD+ in older adults^[6]
Stress, travel and short sleep keep demand high

An illustration of the idea, not a diagnosis. Fatigue has many causes; talk with your physician if it’s persistent.

Why LongevityX made it

A coach’s supplement, not a magic pill

Founder, LongevityXFounder & former CEO, Iconic Protein15+ years in health

William Bosch built Iconic Protein into a national brand, then learned the hard way that you can win in business and still lose your health. After startup stress took its toll, he rebuilt his own body with testing, training and one system run in the right order. Today LongevityX coaches founders, executives and busy adults 40 to 70 to do the same.

His rule with clients is 80/20. Eighty percent of the result comes from the basics: food, strength, sleep and stress. Supplements are the last 20%, and he’s picky about them. NMN is one he often recommends to clients over 40, so LongevityX made a version he’s willing to put his name on: a full 1,000 mg dose, TMG included, and a guarantee long enough to judge it fairly.

80% · food, strength, sleep, stress

20%

Fun fact that makes the point: exercise itself raises your body’s own NAD+-making machinery. In a pooled analysis of training studies, the key enzyme rose about 1.46-fold.^[7] The work comes first. LX NMN+ rides on top of it.*

The science, plainly

How NMN becomes energy your cells can use

NAD+ itself is a large molecule that’s largely broken down in the gut, which is why most human research uses precursors like NMN. NMN is one conversion step away from NAD+.

Two capsules

1,000 mg of NMN each morning.

NMN is absorbed

It sits one step away from NAD+.

NAD+ rises

Human trials show oral NMN raises blood NAD+, and more NMN raises it more.^[1,2]

NAD+ goes to work

Supporting cellular energy production.*

A simplified model of a well-established pathway. Blood NAD+ is what the human trials measured.

What human studies show, and what they don’t

Raises NAD+

Across randomized human trials, oral NMN reliably raised blood NAD+ levels, and the effect grew with dose.^[1,2]

Adults 40 to 65

In a 60-day trial of 80 healthy adults aged 40 to 65, people taking NMN walked farther in a six-minute walk test than people on placebo.^[2]

On top of training

In runners who were already training, NMN for six weeks improved how efficiently their muscles used oxygen during exercise, compared with training alone.^[4]

Studied in older men

In a 12-week trial of healthy older men, daily NMN raised blood NAD+ levels compared with placebo.^[3]

Well tolerated

NMN has been well tolerated in human trials at 250 to 2,000 mg a day for up to 24 weeks.^[5]

What it isn’t

Not a weight-loss pill, not a muscle builder and not a fountain of youth. Pooled studies don’t support those claims, so we won’t make them. That’s what training and food are for.^[5]

What’s inside

Simple on purpose: NMN, plus TMG

Two ingredients, each with a job. No proprietary blend, no fairy dust.

1,000 mgNMN

NMN (nicotinamide mononucleotide)

The direct building block of NAD+. 1,000 mg a day sits within the range used in human trials.^[2,5]

TMGbetaine

TMG, a methyl donor

Your body uses methyl groups to clear the nicotinamide left over from NAD+ metabolism, and in humans a nicotinamide load lowered blood betaine (TMG).^[8] We include TMG as support for that process.*

Testedevery batch

Third-party purity testing

Independent testing has found NMN products holding far less NMN than their labels claim. LX NMN+ will ship with a certificate of analysis for each batch. [Confirm with supplier: COA, country of manufacture, NDI coverage, cGMP facility]

How you’ll know

It won’t feel like caffeine. Here’s how to judge it anyway.

NMN isn’t a buzz. Any effect is gradual, and some people notice little in the first few weeks. So LongevityX does what it does with every client: test, don’t guess.

Day 1

Write down three numbers: your afternoon energy (1–10), how you recover from training, and one workout benchmark.

Week 4

Check in. Keep your training, food and sleep steady so you’re comparing like with like.

Week 12

Compare against day 1. The human trials ran 6 to 12 weeks, so this is a fair window.^[2,4]

Optional

Want real numbers? The LongevityX Health Reset Panel ($299) tests 100+ biomarkers with physician review.

People respond differently, which is exactly why we measure. That’s also why the guarantee is 180 days, not 30.

A note from William

180 days to decide. Not 30.

I’ll be straight with you: LX NMN+ isn’t magic, and no supplement is. If you’re not training, eating real food and sleeping, a capsule won’t save you. That’s the 80%, and it’s what we coach every day.

But if you’re a guy who’s already doing the work, this is the 20% I’d add first. Give it a real run of two to three months. If it isn’t right for you within 180 days, contact our team and we’ll refund your purchase price.

A good fit?

Is LX NMN+ right for you?

It’s for you if

You’re a man 40+ who already does the basics, or is ready to
You want evidence-honest support, not hype or stimulants
You’ll give it two to three months and track how you feel
You like knowing exactly what’s in your capsules, and why

It’s not for you if

You want an overnight fix or a weight-loss pill
You’re under 18, pregnant or nursing
You take medication or manage a condition and haven’t checked with your physician

Questions, answered

Before you choose

How do I take LX NMN+?

Two capsules each morning with water. One bottle is 60 capsules, a 30-day supply. Morning works best for most people; consistency matters more than the exact time.

How soon will I notice anything?

Honestly, it varies, and it won’t feel like caffeine. The human trials ran 6 to 12 weeks, so give it two to three months and use the day-1 / week-12 check above. Some people notice little. That’s why the guarantee is 180 days.

Is NMN safe?

NMN has been well tolerated in human trials at 250 to 2,000 mg a day for up to 24 weeks.^[5] Mild stomach upset, headache or restless sleep if taken late are occasionally reported. Multi-year data doesn’t exist yet. If you take medication or manage a condition, check with your physician first.

Will it help me lose weight?

No, and we won’t pretend it will. Pooled studies haven’t shown NMN changes weight. Weight comes from the 80%: food, strength, sleep and stress. That’s what LongevityX coaching and the free workshop are for.

Why NMN and not an NAD+ pill or NR?

Oral NAD+ is a large molecule that’s largely broken down in the gut, so most research uses precursors. NR and NMN both raise NAD+ in human trials; NMN is one conversion step closer. No head-to-head trial proves either is better.

Is NMN allowed in supplements?

Yes. NMN is sold in the US as a dietary supplement. Like every supplement, LX NMN+ is not “FDA approved”; supplements never are.

Is this a subscription?

No. You choose a one-time package. No auto-ship, no cancellation hoops.

Why get more than one bottle?

One bottle lasts 30 days, and the human trials ran 6 to 12 weeks. Three or six bottles let you give it a fair run without running out, and six bottles cover the full 180 days of your guarantee at the lowest price per bottle.
