New to Longevity Supplements? A Simple Beginner's Starter Stack
TL;DR
New to longevity supplements? Start with just two: NMN (250–500mg daily) to support cellular energy and NAD+ levels, and Creatine Monohydrate (3–5g daily) to support muscle, physical performance and brain health. No loading phase needed for either. Stick with this foundation for 30–60 days before adding anything else, and always check with your GP before starting a new supplement routine.
Longevity supplements can feel like a crowded, confusing category — but getting started doesn't need to be complicated. If you're new to this and wondering where to begin with the Youth & Earth range, this guide gives you a clear, evidence-backed starting point.
You don't need a ten-product protocol. Below, we'll give you our recommended two-product starter stack, show you how to choose products based on your goals, and walk through exactly how to build out the daily habits needed to make the most of your purchases.
The Starter Stack: What, Why and How to Take It
If you're going with our recommended two-product approach, here's exactly what's in it and how the two work together.
- NMN (Nicotinamide Mononucleotide): Supports cellular energy and NAD+ levels. [1]
- Creatine Monohydrate: Supports physical performance, muscle function and brain health. [2]
Between them, these two support the fundamental energy pathways of your cells — NAD+ and ATP — with excellent tolerability. It's the foundation to get right before adding anything else.
We always recommend speaking to your GP before starting any new supplement routine, especially if you have a pre-existing health condition or take medication.
The Science of Synergy: NMN + Creatine
Think of your cells as tiny engines: they need fuel, and they need parts that fire quickly.
NMN is the fuel side of the equation. It provides the raw material your body uses to make NAD+ — and without NAD+, your mitochondria (the cell's power plants) can't produce energy. Studies show that taking NMN supports that production line, potentially helping to offset the natural decline in NAD+ that comes with age. [3] Our NMN Pillar Guide covers the full evidence picture in more depth.
Creatine is the rapid-availability side. It's stored in your muscles and brain, and when you exert energy — lifting something heavy, or thinking through a hard problem — your cells burn through ATP. Creatine steps in to recycle that ATP quickly, keeping your energy levels stable during exertion. See our Creatine Pillar Guide for the details.
Together, NMN supports the production of cellular energy while creatine aids in its rapid recycling and availability — which is why the two work so well as a starting pair.
Dosing Simplicity: Making It a Daily Habit
One of the most common beginner mistakes is overcomplicating things. Keep it simple:
- How to take NMN: 250–500mg daily. Most people take it in the morning to align with the body's natural rhythms, with or without food.
- How to take Creatine: 3–5g (roughly one scoop) daily. No loading phase needed — some athletes load with higher doses for a week to saturate muscles quickly, but for general longevity and wellness a steady, daily dose is all you need. Mix into water, a smoothie, or even your coffee.
Consistency is what matters most here. For supplements to work, they often need to be taken daily. They're seldom quick fixes, and keeping them next to your kettle or coffee machine is a simple way to build the habit.
Creatine Chews
5g of micronised creatine monohydrate in a convenient chewable daily serving.
Shop NowHow to Build From Here (Month 2 and Beyond)
The golden rule with any new supplement routine: start small, listen to your body, and build gradually.
Starting with just one or two products gives your body time to adjust, and gives you a clear baseline for understanding how each one makes you feel. Introduce six products on day one and, good or bad, you won't know which one is responsible.
The month 2 plan: Commit to your foundational stack for at least 30–60 days. This gives the compounds time to build up in your system — creatine especially — and for cellular changes to begin.
After that first month, check in with yourself. Is your energy more sustained? Is recovery a little better? If so, consider adopting the routine for a period of time, but realise that, as with everything in biology, you may need to take a break some months down the line if you notice the positive effects dwindling. Don't worry — a short 2 to 4 week break is normally all that is required for your body to regain its sensitivity to the molecules.
If you want to target something else — perhaps our GLP-1 Support Guide for metabolic health, or Spermidine for targeted healthy ageing — month two is the natural point to introduce one new product at a time, then observe. That deliberate, one-at-a-time approach is what takes you from beginner to evidence-led optimiser.
Making It Easy: Subscriptions, Habit and Quality
Why Quality and Testing Is the Deciding Factor
The UK supplement market is vast, and not every product on the shelf is what it claims to be. Compounds like NMN are genuinely difficult to stabilise and manufacture, and cheap, low-purity alternatives are common.
Every batch of our Core Longevity supplements range is independently third-party tested by US and European laboratories for purity, stability and heavy metals — as we set out in our Brand Trust Pillar. When our label reads "99% pure NMN", that's a certified fact, not a marketing line.
The Subscription Advantage
The real driver of results with longevity supplementation is consistency — the moment you run out, the habit breaks.
Our subscription option means your stack arrives before you need it, at a lower cost than one-off purchases, and you're free to pause, amend or cancel at any time.
How to Choose Based on Your Goal
NMN and creatine form the universal foundation — but if you'd rather start with a single product targeted to an immediate priority, use the decision guide below. You can also take our Product-Finder Quiz for a quick, personalised recommendation based on your goals.
| Your Goal | Recommended Starting Product | Why It Works |
|---|---|---|
| Energy & Vitality | NMN | A direct precursor to NAD+, the molecule your cells need to convert food into energy. May support daily vitality as levels naturally decline with age. |
| Muscle, Brain & Physical Performance | Creatine | Helps your cells recycle ATP (energy) rapidly. Supports muscle strength, exercise performance, and emerging evidence points to cognitive benefits. [4] |
| Metabolic Health & GLP-1 Support | A gut-microbiome / metabolic-support supplement | Supports a healthy gut microbiome and metabolic pathways — useful if you're focused on blood sugar balance or general GLP-1 nutritional support. |
| Healthy Ageing & Cellular Clean-up | Spermidine | A naturally occurring compound that helps trigger autophagy — the body's internal process for clearing out old, damaged cellular components. |
| Appearance (Skin) | Liposomal Glutathione | Provides the antioxidants required to reduce age-related inflammation in the skin. |

Frequently Asked Questions
What supplement should I start with?
For the most evidence-backed starting point for overall cellular health and vitality, we recommend NMN alongside Creatine Monohydrate. NMN supports cellular energy production (NAD+), while creatine supports rapid energy recycling in the brain and muscles.
What's a good longevity starter stack?
A good starter stack prioritises safety, broad benefit and strong human evidence. The Youth & Earth Starter Stack is just two products — 250–500mg of NMN daily alongside 3–5g of Creatine Chews daily — covering cellular energy, muscle function and cognitive support.
How many supplements should a beginner take?
No more than one or two foundational products to start. This avoids overwhelm, keeps cost down, and lets you clearly understand how your body responds before adding targeted extras like spermidine or CaAKG.
Do I need to take supplements forever?
No — supplements support your diet and lifestyle rather than acting as lifelong prescriptions. However, because they work by supporting ongoing cellular processes, such as NAD+ production, their benefits are generally maintained only for as long as you take them consistently.
How do I choose between creatine and NMN?
If your priority is feeling physically tired, muscle recovery, or brain function, start with creatine. If it's the natural energy decline that comes with ageing and deeper cellular repair pathways, start with NMN. Ideally, the two are taken together for a synergistic effect.
