Low Sugar Meal Replacement Shakes, and What the Labels Actually Show
Sugar free is a label term with a legal meaning. Reviews use it loosely, so it is worth checking which products actually carry it.
Protein Drink Mix, Protein Drink Mix Vegan, Beta heart, Fibre Concentrate and Oat Apple Fibre are flagged sugar free on their UK fact sheets. Formula 1 is not, and Tri Blend Select is described as low in sugar rather than sugar free.

Sugar free and low sugar are different claims
Sugar free and low in sugar are two different label claims with different thresholds. A product carrying one is not carrying the other.
The consequence for a shopper is direct. If you are cutting sugar for a specific reason, the wording on the pack is the thing to read, not the review headline.
Which products carry which flag
| Product | Label flag | Per serving |
|---|---|---|
| Protein Drink Mix (PDM) 588g | Sugar free | £1.47 |
| Vegan Protein Drink Mix 560g (PDM) | Sugar free | £1.55 |
| Beta heart® Vanilla 229g | Sugar free | £0.73 |
| Herbalife Fibre Concentrate, Sweet Orange & Goji Berry 500ml | Sugar free | £1.30 |
| Oat Apple Fibre Drink Apple 204g | Sugar free | £1.05 |
| Tri Blend Select - Protein shake mix Banana 600g | Low in sugar | £3.07 |
| Formula 1 Nutritional Shake Mix Vanilla Cream 550g | Not flagged sugar free | £1.26 |
Formula 1 is the shake most people mean by meal replacement, and it is not flagged sugar free. That is worth knowing before you buy it for that reason.

What you give up by choosing on sugar alone
Protein Drink Mix is flagged sugar free and states 15 g of protein per serving. Tri Blend Select is only low in sugar and states 20 g of protein and 6 g of fibre.
So the sugar free option here is not automatically the one doing more nutritionally. Read protein and fibre alongside the sugar flag.
Beta heart is flagged sugar free at 25 calories and 3 g of fibre per serving. It is a low calorie addition rather than a full drink on its own.
Allergens, which catch people out
Protein Drink Mix declares soy and milk. The vegan version declares soy only and is lactose free. Beta heart declares oat and milk.
Tri Blend Select declares oat, so it is plant based but not gluten free. If you avoid gluten, that one rules itself out.
Key points
- Sugar free and low in sugar are separate label claims with different thresholds.
- Protein Drink Mix, the vegan version, Beta heart, Fibre Concentrate and Oat Apple Fibre are flagged sugar free.
- Formula 1 is not flagged sugar free, and Tri Blend Select is low in sugar.
- The sugar free option is not always the one with the most protein or fibre.
- Check allergens too, since soy, milk and oat appear across the range.
