Herbalife Shakes UK, How Meal Replacement Works
What a meal replacement shake is, how it is meant to be used, and what it does not do.
Quick answer: Formula 1 is designed to replace one meal rather than to be added to your day. A 550g tub is about 21 servings. What the rest of your day looks like still decides everything.
Before anything else. If you are taking prescribed medication, or considering it, that is a conversation for your GP or pharmacist rather than for us. Nothing on this page is medical advice and nothing here is a substitute for what they tell you.
What a meal replacement is
A meal replacement is built to stand in for a meal, which is a different thing from a supplement.
That means it is designed to be had instead of breakfast, not alongside it.
Adding a shake to a day you have not otherwise changed adds to that day rather than replacing part of it.
That distinction is the single most misunderstood thing about this product.
It is on the packaging, and it is worth reading before you build a routine.
How it is meant to be used
Two scoops into 250ml of water or milk, once a day, replacing one meal.
Most people use it at breakfast because that is the meal most often rushed or skipped.
Some use it at lunch, particularly if they eat at a desk.
Very few sustain two a day for long, whatever they plan at the start.
The instructions on the tub are the authority here rather than anything we write.

What it does not do
It does not change what happens at any meal you did not replace.
If the difficult part of your day is the evening, a shake at breakfast leaves that untouched.
It is not a treatment, it is not medicine, and it is not a substitute for anything prescribed.
We are not permitted to claim outcomes and we are not going to imply them either.
If you want to know whether it is appropriate for you, ask a GP or a pharmacist.
Choosing a flavour
Smooth Chocolate and Vanilla Cream both work with water alone, which is how most people drink it.
Vanilla takes additions like coffee or berries without clashing, which helps over weeks.
Chocolate is the more immediately likeable and the safer first tub.
Buy one. Three weeks with a flavour you dislike is how people stop entirely.
What a tub costs and lasts
A 550g tub is about 21 servings at roughly £1.26 each.
That is about three weeks at one a day, so day fifteen is a sensible reorder point.
Running out is the most common reason routines stop, and it costs nothing to avoid.
Ordering
No minimum order and delivery is shown at checkout.
Buy one tub of one flavour to start, not three.
Ask us if you are unsure, including if you think none of it suits you.
