What Can I Substitute for Psyllium Husk?

VerdictOne catch
The catch: Cut the extra water the recipe adds for the psyllium by about half, because xanthan gum cannot absorb it and the batter will turn soupy, and note that an Australian recipe's 1 tablespoon of psyllium is 20 ml, not 15 ml.
Xanthan gum binds gluten-free flours and thickens well at a much smaller dose, but it absorbs far less water and gives less stretch, so dough is stickier and harder to shape than a psyllium dough. Full details

What's it doing in this dish?
You're making a yeasted gluten-free sandwich loaf that is baked in a tin rather than shaped by hand.
xanthan gum — 5 g for every 10 g psyllium husk powder (1 tsp)
The tin holds the shape, so losing psyllium's stretch matters less, and xanthan gum or glucomannan can still bind the flours and hold some of the gas as it rises. Cut the extra water for xanthan gum and whisk glucomannan through the dry ingredients first, and expect a lower, finer-crumbed loaf.
You're making a low-carb or almond meal bread or roll where psyllium is what sets the dough.
egg white — 30 g (1 egg white) for every 5 g psyllium husk powder
Egg white is the only substitute here that gives real structure, because its protein sets as it bakes and holds the nut meal together, though the result is springier and eggier. Glucomannan covers the binding and moisture instead, so it suits denser loaves where a chewy, moist crumb matters more than rise.
You're making seed crackers or a nut-and-seed loaf where psyllium glues everything together.
ground chia seeds — 15 g for every 10 g psyllium husk powder (4½ tsp)
These bakes need binding and moisture but no stretch, which is exactly what ground chia and ground linseed cover. Their seedy flavour and flecks also sit comfortably in a cracker or seed loaf where they would stand out in plain bread.
You're making gluten-free muffins, pancakes or a quick bread that rises with baking powder rather than yeast.
xanthan gum — 5 g for every 10 g psyllium husk powder (1 tsp)
guar gum — 5 g for every 10 g psyllium husk powder (1 tsp)
A batter only needs binding and a little thickening to hold its crumb, so the gums do the job without psyllium's stretch. Halve the extra water the recipe adds for the psyllium, and the crumb will come out finer and more cake-like.
You're thickening a smoothie, a pudding or a low-carb sauce without cooking it down.
xanthan gum — 5 g for every 10 g psyllium husk powder (1 tsp)
ground chia seeds — 15 g for every 10 g psyllium husk powder (4½ tsp)
Here psyllium is only thickening, and xanthan gum thickens without heat at a smaller dose, giving a smoother result in sauces and drinks. Ground chia suits puddings and smoothies where a slightly seedy texture is welcome, but give it 10 minutes to gel.
You're rolling out gluten-free wraps or flatbreads, or hand-shaping rolls, bagels or a free-form loaf.
Nothing really replaces it here.
These recipes depend on psyllium's flexible gel to let a gluten-free dough be kneaded, rolled thin and folded without cracking, and none of the substitutes gives that stretch. Gums, seeds and egg white bind, but the dough tears, sticks or slumps, so buy psyllium or choose a recipe baked in a tin.
What Psyllium Husk does in a recipe
structure & stretch · primary — Its soluble fibre forms a flexible gel that stands in for gluten, so gluten-free dough can be kneaded and shaped, traps gas as it rises, and bakes into bendable wraps and loaves.
binding · primary — The sticky gel glues gluten-free flours, nut meals and seeds together so breads, crackers and bases hold together when sliced instead of crumbling.
moisture · secondary — It absorbs and holds many times its weight in water, keeping gluten-free and low-carb breads soft and slowing them from going dry and crumbly.
thickening · secondary — It thickens liquids without heat within a few minutes, which is why it turns up in smoothies, chia-style puddings and low-carb sauces.

glucomannan (konjac powder)
One catch
3 g for every 10 g psyllium husk powder (1 tsp)
Glucomannan is another soluble fibre that gels strongly and binds and holds water much as psyllium does, but it is more potent and clumps easily.
The catch: Whisk it thoroughly through the dry ingredients before any liquid goes in, because it forms hard lumps the moment it touches water on its own.
Covers
binding, moisture, thickening
Misses
structure & stretch
Taste
Close to neutral, with a faint earthy note in large amounts.
Texture
Breads are moist and chewy but less elastic, and an overdose makes them rubbery.
Looks
The crumb looks similar, though loaves rise a little less.
Best for
low-carb breads, thickening sauces and puddings, gluten-free flatbreads
Guar gum binds and thickens at a small dose, especially in cold or quick-baked mixtures, but like xanthan it gives little stretch and holds less water than psyllium.
The catch: Reduce the extra water the recipe adds for the psyllium by about half, or the mixture will be too wet to set.

Taste
Neutral in small amounts, but a slightly beany note can come through if overused.
Texture
Baked goods are softer and more tender, and can turn gummy if you add too much.
Looks
Expect a flatter rise and a closer, denser crumb in yeasted loaves.
20 g for every 10 g psyllium husk powder (1½ tbsp)AU tbsp = 20ml
Ground linseed forms a weaker gel that binds and holds moisture at about double the amount, but it cannot give a gluten-free dough the stretch psyllium does and it changes the flavour and colour.

Taste
Adds a nutty, slightly grassy flavour that is obvious in plain bread.
Texture
The crumb is denser, moister and more crumbly, with little chew.
Looks
Brown linseed darkens the crumb and leaves visible flecks; golden linseed is less noticeable.
30 g (1 egg white) for every 5 g psyllium husk powder
Egg white binds and sets the structure of gluten-free and low-carb bakes as its protein cooks, but it gives a spongy, eggy crumb rather than psyllium's chewy, bread-like one.

Taste
Noticeably eggier, especially in plain loaves.
Texture
Lighter and springier but drier, and it stales faster than a psyllium bread.
Looks

Commonly tried, but skip these
People reach for these, and they let you down.
cornflour or extra starch
Skip it
People reach for cornflour or more gluten-free flour because it is in the cupboard and thickens gravy, but starch adds no sticky network, so the dough cannot be shaped and the bake crumbles; in Australia, check the label too, as some cornflour is made from wheat and is not gluten-free.

When to buy the real thing
The recipe is a hand-shaped gluten-free bread, bagel, pizza base or wrap that you knead, roll or stretch.
Instead: Buy psyllium husk powder, which is sold in most Australian supermarkets in the health food aisle, at chemists as a plain fibre supplement and at Indian grocers as isabgol, and check it is unflavoured with no added sugar.
The recipe uses a large amount of psyllium, such as a low-carb loaf where psyllium and almond meal are most of the dough.
Instead: Choose a different recipe written for xanthan gum or egg white, because swapping out the main structural ingredient changes the whole bake rather than one element of it.
You have whole psyllium husk but the recipe calls for psyllium husk powder.
Instead: Grind the whole husk to a fine powder in a spice grinder or blender and weigh it rather than measuring by volume, because whole husk is much bulkier per spoonful than powder.
Rescue a swap gone wrong
The gluten-free dough is a runny batter that won't hold any shape.
Why: The recipe added extra water for the psyllium to absorb, and xanthan gum or guar gum cannot soak up anywhere near as much.
Fix: Work in more of the recipe's gluten-free flour a little at a time until it firms up, then bake it in a greased tin instead of shaping it, and next time cut that extra water by about half.
The baked bread is gummy, slimy or rubbery in the middle.
Why: Too much gum or glucomannan was used, often because an Australian 20 ml tablespoon was used for a recipe written with 15 ml tablespoons, or the substitute was swapped one for one with the psyllium.
Can't be fixed — next time: Toast slices well to dry out the gumminess, and next time weigh the substitute in grams or use a 15 ml measure, keeping to the reduced amount.
There are hard jelly-like lumps through the sauce, pudding or dough.
Why: Glucomannan or xanthan gum was added straight to the liquid, and it gelled into clumps before it could disperse.
Fix: Blitz sauces, puddings and smoothies with a stick blender or push them through a sieve; for dough, there is no way to remove the lumps, so next time whisk the powder through the dry ingredients before any liquid goes in.
The loaf crumbles and falls apart as soon as you slice it.
Why: Linseed, chia or starch bound the crumb too weakly without psyllium's gel, and slicing while warm makes it worse because the crumb has not set.
Can't be fixed — next time: Let the next loaf cool completely before slicing, and turn this one into toasted crumbs or croutons; for a sliceable loaf next time, use xanthan gum or egg white rather than seeds or cornflour.
Key numbers
Dietary fibre
about 80%Most of the husk is fibre, much of it soluble, which is why a small amount absorbs so much water and why any substitute needs a different amount and water level.
Differences between countries
Ispaghula husk in chemists (United Kingdom)
In the UK, psyllium is often sold in chemists as ispaghula husk, mainly as sachets that are frequently flavoured or effervescent. These are not suitable for baking, so look for plain, unflavoured ispaghula or psyllium husk.
In the US and Canada, much of the psyllium on pharmacy shelves is sold as a flavoured fibre drink powder with added sugar or sweetener, colour and flavouring. Baking recipes need the plain, unflavoured husk or powder, which is usually shelved nearby or sold in health food stores.
Applies to Australia
Whole husk versus powder (Australia, United Kingdom, New Zealand, United States, Canada)
Packs labelled simply psyllium husk are often the whole, flaky husk, not the fine powder many bread recipes call for. The two weigh very differently per spoonful, so check the label and weigh in grams where you can.

Questions people ask
Can I use whole psyllium husk instead of psyllium husk powder?
Yes, but grind it to a fine powder first and use the same weight in grams. Whole husk is much fluffier than powder, so a spoonful of whole husk holds noticeably less, and measuring by volume will leave the dough short. Unground husk also gives a coarser, grittier crumb.
How many grams is a tablespoon of psyllium husk powder?
A 15 ml tablespoon of psyllium husk powder weighs roughly 10 g, though it varies with how finely it is milled. An Australian 20 ml tablespoon holds about a third more, so if a recipe was written with 15 ml tablespoons, weigh the powder rather than using an Australian tablespoon.
Is psyllium from the chemist the same as the psyllium used in baking?
Plain, unflavoured psyllium from the chemist is the same product as the kind sold for baking. Flavoured fibre drink powders are not, because added sugar, sweetener, colour and flavouring will show up in the bread, so check the ingredients list says only psyllium husk.
Can I leave psyllium husk out of gluten-free bread?
No, not without replacing it, because it is usually what holds the dough together. Without it a gluten-free bread will be dense and crumbly and will fall apart when sliced. If you have none, use xanthan gum in a loaf baked in a tin, or egg white in a low-carb bread.
Why did my psyllium bread turn purple or grey?
Some psyllium powders turn the crumb purple, grey or blue-ish during baking, and it varies between products. The colour change does not affect the flavour or texture. Switching to a different psyllium product usually stops it happening.
Do I need to rest psyllium dough before shaping it?
Yes, give it 5 to 10 minutes after mixing. The psyllium needs that time to absorb the water and form its gel, and the dough firms up from a sticky paste into something you can knead and shape. If it is still too soft after resting, work in a little more flour.
Where Psyllium Husk comes from
Psyllium husk is the outer seed coating of Plantago ovata, a plant grown mainly in India. The husk is separated from the seed and sold whole or milled into a fine powder.
Psyllium Husk is usually dairy-free, vegan, gluten-free, nut-free — check the label, and see the disclaimer.
