Your First Supplement Stack (2026 UK Guide)

You do not need a cupboard full of tubs to start supplementing well. Most people who train 3–4 times per week get 80% of the benefit from three basics: protein, creatine, and vitamin D. Everything else is optional — and should match a clear goal.

The core stack (what to buy first)

1. Whey protein — close your daily protein gap

Aim for 1.6–2.2 g protein per kg body weight daily. If whole food falls short, one shake per day is enough for most beginners.

Our pick:

Mix with Applied Nutrition Flavo Drops (£4.99) for custom flavour without buying multiple tubs.

2. Creatine monohydrate — the most proven ergogenic

3–5 g daily, no cycling required. Take it every day, training or rest.

Upgrade later to

when you want certified German quality.

3. Vitamin D3 — especially October to March in the UK

NHS guidance recommends 10 µg (400 IU) daily for most adults in autumn and winter; many athletes use higher-strength products under guidance — check the label.

Pair with our vitamin D guide for dosing detail.

Optional add-ons (only if they solve a real problem)

For long sessions, see our hydration guide.

What to skip at the start

• Fat burners and "detox" blends
• Proprietary "muscle matrix" powders with hidden doses
• Buying five flavours of whey before you finish one tub

Sample monthly cost on GymStack

Core stack (whey + creatine + vitamin D): roughly £55–75/month depending on tub sizes and how often you shake vs eat protein. That is less than one unused supplement graveyard in your kitchen.
