Frequently Asked Questions
What are the best fibre supplements available in South Africa?
FtN stocks a range of fibre supplements including psyllium husk, inulin, acacia fibre, and chia seeds. For regularity and bowel health, psyllium husk is one of the most studied options, available in powder and capsule form. For prebiotic fibre that feeds beneficial gut bacteria, inulin and acacia are strong choices. All options on FtN are vetted for clean formulations without unnecessary additives.
What is the difference between soluble and insoluble fibre?
Soluble fibre dissolves in water to form a gel that slows digestion and feeds beneficial gut bacteria, making it a natural prebiotic. Insoluble fibre adds bulk to stool and speeds its movement through the bowel, directly supporting regularity. Most high-fibre foods and many supplements contain both. Psyllium husk is particularly valued because it is rich in both soluble and insoluble fibre.
What is psyllium husk used for?
Psyllium husk is a plant-derived soluble fibre widely used to support bowel regularity and relieve constipation. Research also suggests it may help manage cholesterol and blood sugar levels. It is taken mixed with water or juice and must always be consumed with adequate fluid. FtN stocks psyllium husk in powder and capsule form. For broader gut microbiome support, consider pairing it with a probiotic supplement.
Can fibre supplements support gut health?
Yes. Certain fibre supplements, particularly prebiotic fibres such as inulin, FOS, and acacia, actively feed beneficial gut bacteria and support microbiome diversity. Soluble fibre also helps regulate bowel transit time and maintain a healthy gut lining. For a more targeted approach, pairing a fibre supplement with a probiotic from our prebiotics and probiotics range may offer broader digestive support.
Are there organic fibre supplements available?
Yes. FtN carries organic fibre options including organic psyllium husk and organic chia seeds. All products are vetted for ingredient quality, and certified organic options can be filtered easily using the organic filter in the category. This lets you narrow the full range to certified options without browsing every product individually.
How much fibre should I take per day?
South African dietary guidelines recommend around 25–30g of fibre per day for adults. Most South Africans fall well short of this through diet alone. A fibre supplement can bridge the gap, typical supplement doses range from 5–10g per serving. Introduce supplemental fibre gradually to avoid temporary bloating, and drink plenty of water with each dose to help it work effectively.
What is the difference between inulin and psyllium husk?
Inulin is a prebiotic fibre derived from chicory root that feeds beneficial gut bacteria with minimal impact on bowel transit. Psyllium husk is primarily a bulking agent that supports regularity and bowel movement. They serve different purposes, inulin is more suited to microbiome support, while psyllium husk is better for constipation relief and cholesterol management. Both are available in the gut health range at FtN.
