By Vitadefence Team

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.
What is Soy Fibre Multi?
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. The chicory root fibre, also known as inulin, acts as a prebiotic, supporting the growth of beneficial gut bacteria. Added to this are 14 vitamins and minerals, carefully included to help fill common nutritional gaps in a typical diet.
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.
Vitadefence Soy Fibre Multi ingredients
Each 300 g pot contains 12 servings. The ingredient panel is as follows:

How the formula was designed
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. The chicory root fibre adds soluble fibre, which has been studied for its role in supporting digestive regularity and promoting a healthy gut microbiome.
The vitamin and mineral blend targets nutrients that are commonly under-consumed in modern diets. 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.
The science — what’s well-supported
Several of the nutrients in Soy Fibre Multi have authorised health claims under EU Regulation 1924/2006. 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, which is important for cardiovascular health.
- 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.
Regarding the protein and fibre components: Soy protein isolate has been shown in clinical trials to support muscle protein synthesis when consumed as part of a balanced diet. A 2018 meta-analysis in the Journal of the International Society of Sports Nutrition found that soy protein supplementation can support lean mass gains when combined with resistance training. Chicory root fibre (inulin) has been studied for its prebiotic effects, with research indicating it can increase beneficial Bifidobacteria in the gut and improve stool frequency in adults with constipation (PubMed ID: 26218677).
It’s important to note that the EU Register of Health Claims does not currently authorise a specific claim for chicory root fibre in relation to digestive health, but the traditional use of inulin as a dietary fibre is well recognised. The product is not intended to diagnose, treat, or prevent any disease.
How to take it
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.
One serving provides approximately 20 g of protein and a significant amount of fibre, depending on the liquid you choose. It’s a good idea to start with one serving per day and adjust based on your individual needs and tolerance.
Storage
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.

Frequently asked questions
Is Soy Fibre Multi suitable for weight management?
As part of a calorie-controlled diet, the protein and fibre in Soy Fibre Multi can help promote satiety, which may support weight management goals. However, it is not a weight loss product per se, and no specific health claims are made in this regard.

Yes, Soy Fibre Multi is naturally gluten-free. However, it is produced in a facility that handles gluten-containing ingredients. If you have coeliac disease or severe gluten sensitivity, please contact us for further information about our manufacturing processes.
