Which Herbalife Products Are Gluten-Free, Vegan or Vegetarian? (19 UK Products Checked)

Of the 19 UK Herbalife products checked directly against their official labels for this guide, 4 are confirmed gluten-free, 4 are confirmed vegan, and 9 more are vegetarian but not vegan — most commonly due to milk-derived ingredients such as whey, casein or sodium caseinate, or fish oil and gelatine in the chewable gel and omega-3 range.

Every classification below comes from ingredient lists and allergen statements on official UK product labels, not marketing claims or assumptions.

How This Guide Was Made

This guide is based on direct review of 19 official UK Herbalife product labels — ingredients lists, allergen statements, and on-pack claims. Products are classified strictly according to label wording, not marketing language or assumptions.

Confirmed Gluten-Free Products

Four products carry an explicit “gluten-free” statement on their UK label, rather than an ingredient-based inference.

• Formula 1 Healthy Meal — label states vegan-sourced ingredients and gluten-free; soy-free and gluten-free when mixed with cow’s milk.
• Vegan Protein Drink Mix — label states gluten-free and naturally lactose-free.
• Instant Herbal Beverage — label states gluten-free (contains 87.5mg caffeine per serving).
• Tri Blend Select — label explicitly states “gluten free,” using gluten-free oat fibre as an ingredient.

Confirmed Vegan Products

• Vegan Protein Drink Mix — 100% vegan, no animal-derived ingredients.
• Tri Blend Select — pea, flax and quinoa-based; no dairy, soy or animal ingredients.
• Oat Apple Fibre Drink — all six fibre sources (oat, apple, maize, soya, citrus, chicory) are plant-based.
• Formula 1 Healthy Meal — vegan-sourced as a powder, but see the preparation note below, since the finished shake’s suitability depends on what liquid it’s mixed with.

Vegetarian But Not Vegan Products

These products contain milk-derived ingredients (whey, casein, sodium caseinate) or milk chocolate coatings, making them unsuitable for vegans but fine for vegetarians.

• Formula 3 Personalised Protein Powder — whey protein concentrate (milk).
• High Protein Iced Coffee — whey protein concentrate and sodium caseinate (milk).
• Herbalife24 Rebuild Strength — milk protein concentrate, whey protein concentrate and isolate, calcium caseinate; may contain soy and egg.
• Beta Heart — contains sodium caseinate (milk); also contains oat and may contain other gluten sources.
• Microbiotic Max — its GOS fibre is derived from lactose (milk); gluten-free, may contain soybeans.
• Formula 1 Express Bar and Protein Bar Achieve (H24) — vegetarian-labelled, but both may contain gluten, nuts, eggs and peanuts, and their chocolate coatings contain milk.

Not Vegetarian or Vegan

These products contain fish, fish oil, gelatine, or other animal-derived ingredients that rule out both vegetarian and vegan diets.

• Collagen Skin Booster — contains VERISOL® bioactive collagen peptides, sourced from porcine (pig) collagen.
• Herbalifeline Max — the capsule shell is vegetarian, but the fill is fish oil, so the finished product contains fish.
• Herbalife Gels MindVita Kids and ViewVita — contain both fish oil concentrate and gelatine.
• Herbalife Gels CoQ10Vita and NutrientVita Kids — contain gelatine (no fish oil, but gelatine alone is enough to rule out vegetarian and vegan diets).

Gluten-Free vs. “May Contain Gluten”

These two label statements are not interchangeable. “Gluten-free” is a direct statement about the product’s formulation. “May contain gluten” is a cross-contamination warning about shared manufacturing equipment. For anyone with coeliac disease or a severe gluten intolerance, this distinction matters — a “may contain” product is not the same as a confirmed gluten-free one, even if gluten isn’t a deliberate ingredient.

Why Preparation Method Matters for Formula 1

Formula 1 Healthy Meal’s powder is formulated with vegan-sourced ingredients, but the finished shake’s dietary status depends on what it’s mixed with. It’s gluten-free and soy-free when made with cow’s milk, lactose-free and gluten-free when made with a fortified soy beverage, and dairy-free, gluten-free, soy-free and vegan when made with other plant-based beverages — though in that case it no longer meets the “meal replacement” nutritional profile stated on the label.
