PHGG
Also called partially hydrolysed guar gum, partially hydrolyzed guar gum, sunfiber, guar gum fibre.
The best price per 5 g and per month, form by form, across 1 UK retailer, and where to buy it cheapest. A unit for comparing, not advice.
Comparing PHGG
We count the partially hydrolysed guar gum a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Products that combine PHGG with other ingredients are listed separately, because their price buys more than partially hydrolysed guar gum. 5 g is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

67p per 5 g, for Bio.Me Prebio PHGG at Healf (67p per 5 g, £19.95 a month), on 20 October 2026. It is the one PHGG product we price from a UK seller so far.

At one 5 g dose a day, the cheapest works out at £19.95 a month, for Bio.Me Prebio PHGG at Healf, on 20 October 2026. A month is 30 days, and the figure follows the dose you enter in the table.
What does “per 5 g” mean?
It is the unit we use to put every product on the same scale: the price of 5 g of partially hydrolysed guar gum, whatever the pack size or serving size. It is a comparison unit, not a recommendation of how much to take. Use the “Your daily dose” box to see costs at the amount you actually take.
Why is a product I have seen in the shops missing?
If a retailer’s listing does not let us confirm the amount per serving, the pack size or the form, we do not guess and we do not show the product. It appears once its label has been read and confirmed.
How up to date are the prices?
Prices on this page were last checked on 20 October 2026. Every table shows the date its prices were checked. Always confirm the price on the retailer’s site before buying.
Do retailers pay to appear higher?
No. We earn a commission when you buy through our links, but the order is set only by price per dose. No retailer or brand can pay for position.
