Fibre Supplements

This category lists fibre supplements as powders, capsules, liquids and gummies, and each product page shows the fibre amount its own label declares. The table below compares the price of 5 g of declared fibre for three products, so pack prices can be compared on the same basis. A product whose label gives only the weight of an ingredient, such as a psyllium husk capsule, has no declared fibre amount and is not in the table.

Portion prices are calculated from the net contents. Portion sizes differ between products; this is not a dosing recommendation. Read the full ingredients and directions on the product label.

Price per 5 g fibre = portion price ÷ declared fibre per portion (g) × 5. Only the fibre the label declares is counted, not the weight of the powder or liquid.

Frequently asked questions

What does the fibre amount on a label mean?

It is the amount of fibre, in grams, that one serving declares. Check it against the serving size printed on the same label, because the same number of grams can come from very different servings.

Why is a fibre product missing from the comparison table?

A label that gives only the weight of an ingredient, such as "psyllium husk 610 mg", does not say how much fibre a serving contains. Without a fibre amount on the label, the price per 5 g of fibre cannot be worked out, so the product is left out.

How should I take a fibre supplement?

Follow the serving size and mixing instructions on the label and drink the amount of water or other fluid it gives. If you are pregnant or breastfeeding, take medicines or have a medical condition, check the label warnings or ask a doctor or pharmacist first.
