What is Daily Fiber?

A once-a-day psyllium sachet with digestive enzymes, built to give stool one shape whichever way your week goes. Thirty seconds, one glass of water, no scoop.

Works both ways

Firms up what is loose. Softens what is hard. The same sachet, either problem.

No scoop, no guessing

One sachet is one serving, already measured. It fits in a pocket.

Four ingredients

Psyllium husk, tamarind, ginger, digestive enzymes. Every one of them named on the pack.

Four actives that earn their place

Eight ingredients on the label. Four of them do work. Here is what each one is for.

Psyllium husk, ground fine

Psyllium husk

3,000 mg

A gel-forming fiber, and the most studied fiber there is. Firms what is loose, softens what is hard, with no stimulant.

Most fiber gets eaten on the way through. This one survives.
Digestive enzyme blend powder

Enzyme blend

30 mg

Four digestive enzymes, one for each part of a meal. Amylase for starch, lactase for dairy, lipase for fat, cellulase for plants.

Most fiber drinks only handle what leaves. This handles what arrives.
Tamarind pods

Tamarind

60 mg

A fruit pulp extract. A food, not a laxative herb. It brings its own fiber and fruit acids, so things keep traveling instead of stalling.

Senna is the usual shortcut. There is none of it in here.
Fresh ginger root

Ginger root

15 mg

Fresh ginger concentrated into an extract. It works on the stomach while the fiber works further down, at the same time.

Fiber can leave a heavy feeling. The ginger is there to answer it.

The science behind Daily Fiber

Two questions decide whether a fiber works. Most of the shelf fails one of them.

It binds loose liquid

Firmer stools

It does not take the water away. It turns it into a gel. In one trial the same nine people got firmer, thicker stool on psyllium, and nothing at all on wheat bran.

Eherer et al., 1993

It survives the trip

Still a gel at the end

Psyllium has been recovered from human stool still intact, and still a gel, all the way through.

Marlett et al., 2000

It feeds slowly

Less gas

People with IBS drank twenty grams of inulin and their gut filled with gas. The same drink with psyllium made no more gas than plain sugar water.

Gunn et al., 2022

They tried everything else first

Gave me more freedom around meals

I have gallbladder dysfunction where my gallbladder releases too much bile. I took 1 of this 15 mins before eating a delicious steak dinner (over 50g of fat) and had zero issues!

Daphne N.Verified Buyer

Much easier on me than prescriptions

As a person with IBS-C, I am able to use these instead of the prescription medicine. I can take one at night and go the next morning without feeling drained.

Valerie C.Verified Buyer

Years of stomach issues finally improved

My bowel habits are dramatically more predictable, the cramping has essentially disappeared. No other product has regulated my digestive system this effectively.

4 reasons your gut will stop surprising you

A jar of Daily Fiber passed across a kitchen counter 1.

One shape, both ways

Loose stool firms up. Hard stool softens. It is a physical effect, not a stimulant, so there is nothing to get used to.

A customer holding the jar in her kitchen 2.

Not a speed dial

A laxative makes it go faster. An anti-diarrheal makes it go slower. Neither changes what is actually in there. This does.

A customer laughing, holding the jar 3.

Nothing to plan around

Not a better bathroom routine. Just one less thing you have to build your day around, and one less thing on your mind.

The jar on a bedside table 4.

Thirty seconds a day

One sachet into a tall glass of still water. Drink it straight down. Thirty in the jar, nothing to scoop and nothing to weigh.

Free with every order

Free shipping over $75. $4.99 under. Delivered in 3 to 9 days.

60Day

Regular in sixty days, or your money back

Fiber is not a switch. It is a habit that compounds. Take one sachet a day for sixty days and give your gut the whole run at it. If you are not regular by then, email us and we will refund the order.

What is in it?

Psyllium husk 3,000 mg. Tamarind 60 mg. Ginger 15 mg. Digestive enzyme blend 30 mg, which is amylase, lactase, lipase and cellulase.

Natural raspberry, sweetened with stevia leaf. No added sugar. Gluten free, vegan, non-GMO.

How do I take it?

Thirty seconds, once a day. Stir one sachet into a tall glass of still water, about 8 oz. Drink it straight away, before it thickens.

New to fiber? Use half a sachet for the first few days and let your gut catch up. There is no prize for rushing. One a day is where you start, not where you stop.

Is this for me?

If any of this sounds like your week, you are in the right place. Some days loose and urgent. Other days slow and hard. You know where the bathroom is in every place you go. You have added fiber before and nothing changed.

None of that makes you difficult or broken. It suits most adults, whatever you eat.

Frequently asked questions

What does it taste like?

Natural raspberry. Drink it quickly and it is a light drink, not a thick shake.

Does it go clumpy?

Only if it sits. It starts to thicken in about ninety seconds, so let it thicken in you, not in the cup.

Will it make me gassy at first?

It can for the first few days, and that is normal. Your gut is meeting fiber it has not had in a while. Start on half a sachet and it settles.

Does it still feed my gut bacteria?

Yes. About fifteen percent of psyllium husk is fermented, so your bacteria still get fed. The rest arrives relatively intact, and that is the part that stays a gel.

How is this different from what I already tried?

Most of the shelf changes your speed. A laxative makes everything go faster. An anti-diarrheal makes everything go slower. Neither changes what is actually in there.

Psyllium does something different. It turns to gel in water, and the gel gives stool its form. Firm enough when everything is loose, soft enough when everything is stuck.

Why we made it

The orange tub in the aisle is psyllium plus chemicals. Aspartame, Yellow 6, Blue 1. It has been the default for thirty years, and it works.

We are psyllium plus three more plants.

Tamarind, ginger and a digestive enzyme blend, in a pre-measured sachet instead of a tub and a scoop. Same fiber, a shorter label, and three more things doing work. That is the whole idea.
