Formula 1 – current flavours and prices
What Formula 1 actually is
Formula 1 is a powdered shake mix sold in 550g and 780g tubs. You add 2 scoops (approximately 26g) to 250ml of semi-skimmed milk, shake or blend, and drink it as a meal. The whole process takes under 2 minutes.
It is regulated in the UK under the Food for Specific Groups Regulations 2016, which set mandatory nutritional standards for meal replacement products. This means it must meet specific requirements for protein, vitamins, minerals, and calorie content to legally be sold as a meal replacement — it is not just a protein shake with a label.
It is available in over 10 flavours in the UK, all at the same price of £24.96 per 550g tub at member discount prices.

How Formula 1 works
Formula 1 works by replacing one meal per day with a nutritionally complete, calorie-controlled shake. The mechanism is simple: most people consume their highest-calorie, lowest-nutrition meal at breakfast or lunch — either skipping it entirely, grabbing something high-calorie on the go, or eating something with little nutritional value.
Replacing that meal with a Formula 1 shake provides defined calories, defined protein, and 21 vitamins and minerals — consistently, every day, in under 2 minutes. Over weeks and months, that consistency creates the calorie deficit and nutritional structure that produces results.
Which flavour should I choose?
Vanilla Cream – best first choice
The most popular and versatile Formula 1 flavour in the UK. Works on its own and as a base for fruit, coffee, or other additions. Start here if you are unsure.
Smooth Chocolate – best for chocolate fans
Classic milk chocolate flavour. Best if you specifically want a chocolate shake and plan to drink it daily without additions.
Banana Cream – best for fruit routines
Sweet banana flavour that works well blended with frozen fruit. Good for people who prefer fruit-led shakes.
Other flavours
Café Latte, Summer Berries, Mint Chocolate, Cookie Crunch, Strawberry Delight, Strawberry Watermelon, and Free From Raspberry & White Chocolate. See the full flavour guide.
Is Formula 1 right for me?
Formula 1 is most useful if you regularly skip breakfast, buy a high-calorie lunch on the go, or struggle to eat a nutritionally balanced meal at one point in the day. It removes the decision and the preparation from that meal slot.
It is less useful if you already eat a well-structured, nutritionally balanced breakfast or lunch consistently. In that case, the problem is not the meal — it is something else in the day.
It is not suitable as a casual plan for people who are pregnant, under 18, have a history of eating disorders, diabetes, kidney disease, or are taking medication. Consult your GP first.
