Soy Fibre Multi (Vanilla): Ingredients, Dose and Label Facts

If you’re looking for a convenient way to support your daily fibre intake while getting a solid dose of plant-based protein and essential vitamins and minerals, the Vitadefence Soy Fibre Multi might be exactly what you need. This vanilla-flavoured powder combines soy protein isolate with chicory root fibre and a comprehensive vitamin and mineral blend, making it a practical addition to your routine—whether you’re blending it into a shake, stirring it into yoghurt, or adding it to a smoothie bowl.

Soy Fibre Multi is a versatile, plant-based powder designed to provide a dual benefit: a source of high-quality protein from soy and a dose of soluble fibre from chicory root extract. Soy protein isolate is one of the few plant proteins considered a complete protein, meaning it contains all nine essential amino acids that the body cannot produce on its own. Chicory root fibre is a source of inulin. Added to this are 14 vitamins and minerals, 15 vitamins and minerals, each at least 15% of the NRV per 25 g serving.

This product is categorised as a fibre supplement, but it’s much more than that. It’s designed for anyone who wants a simple, one-scoop solution to increase their protein intake, boost fibre, and top up on micronutrients—all in one serving.

Each 300 g pot contains 12 servings. The ingredient panel is as follows:

• Soy (Glycina Maxima) Protein Isolate – a complete plant protein
• Fibre (Chicory Root (Cichorium intybus) Extract) – a source of inulin, a prebiotic fibre
• Natural Flavour
• Maltodextrin
• Vitamin and Mineral Blend: Potassium Chloride, Magnesium Citrate, Vitamin C (Ascorbic Acid), Ferrous Citrate, Zinc Citrate, Copper Citrate, Vitamin E (DL-Alpha-Tocopheryl Acetate), Vitamin B3 (Niacin), Vitamin A (Acetate), Vitamin B12 (Cyanocobalamin), Vitamin B2 (Riboflavin), Vitamin B6 (Pyridoxine Hydrochloride), Vitamin B1 (Thiamine), Folic Acid (Folacin), Potassium Iodide
• Sweetener: Stevia Leaf Extract (Steviol glycosides)

Per 100 g, the product provides: Vitamin A 800 µg (2664 IU), Vitamin E 12 mg (17.9 IU), Vitamin C 80 mg, Thiamine 1.1 mg, Riboflavin 1.4 mg, Niacin 16 mg, Vitamin B6 1.4 mg, Folic acid 200 µg, Vitamin B12 2.5 µg, Potassium 1205 mg, Chloride 542 mg, Phosphorus 615 mg, Magnesium 378 mg, Iron 14 mg, Zinc 10 mg, Copper 1.3 mg, Iodine 150 µg.

The Soy Fibre Multi formula was created with practicality in mind. The base of soy protein isolate provides a complete amino acid profile, which is especially valuable for those following a vegetarian or vegan diet.

For example, magnesium, zinc, and iron are frequently low in plant-based eating patterns, while B vitamins are essential for energy metabolism. The inclusion of iodine is particularly thoughtful, as iodine status can be suboptimal in some populations, especially those avoiding dairy and seafood.

The use of stevia as a sweetener keeps the product low in added sugars, and the natural vanilla flavour makes it easy to incorporate into a variety of recipes without overpowering other ingredients.

Several of the nutrients in Soy Fibre Multi have authorised health claims under the UK Nutrition and Health Claims Register. For instance:

• Vitamin B6, B12, Thiamine, Riboflavin, Niacin, and Vitamin C all contribute to normal energy-yielding metabolism. This means they help your body convert food into usable energy.
• Vitamin B6, B12 and folic acid contribute to normal homocysteine metabolism.
• Vitamin C, Vitamin E, Zinc, and Copper contribute to the protection of cells from oxidative stress.
• Iron contributes to normal cognitive function and the formation of red blood cells and haemoglobin.
• Magnesium contributes to normal muscle function and electrolyte balance.
• Iodine contributes to normal cognitive function and thyroid function.

Protein contributes to a growth in muscle mass.

The authorised chicory inulin claim needs 12 g a day; our label does not state the inulin amount. The product is not intended to diagnose, treat, or prevent any disease.

For best results, add 1 scoop or 3 heaped teaspoons (25 g) to a glass. Mix with water, fruit juice, soya milk, or another liquid of your choice for a high-protein shake. You can also be adventurous—add it to yoghurt, mix with berries, or blend it into smoothies and porridge. The powder has a mild vanilla flavour that pairs well with most fruits and plant-based milks.

Protein and fibre per serving: see the nutrition table on the pot. It’s a good idea to start with one serving per day and adjust based on your individual needs and tolerance.

Store in a cool, dry place, out of reach of children. Do not use if the seal is damaged. The best before date is printed on the base of the pot. Once opened, use within three months for optimal freshness.
