GUT HEALTH · FROM OPTIMAL HUMAN

Your gut needs 3 things.
You only give it 1.

The first one is easy to buy anywhere. The other two are the ones almost nobody tells you about.

Gut health, made simple

Ever feel puffed up after a normal meal? Or heavy and slow, and not sure why?

Most people try one thing for that. A probiotic pill. A fiber gummy. A scoop of greens. One thing is a fine start.

But your gut is doing three jobs at once. Buy only one and you are helping with one third of the work.

Here are all three, and how to tell which ones you are already getting.

Part01

Good bacteria. The easy one to buy.

Three bowls side by side holding three different powders

Your gut is full of tiny living helpers. Most people know them as good bacteria. You can buy them anywhere, and that is the easy part.

They help break your food down and pull the good out of it. The more kinds you have in there, the more jobs get covered. This scoop has thirteen kinds of good bacteria, and ten billion of them. Every kind is printed on the label, not hidden inside a blend.

That is job one of three. Most things you can buy stop right here.

Part02Nobody mentions this one

Food for that bacteria.

Good bacteria is alive. Living things have to eat or they do not last.

What it eats is fiber. Not the kind that only moves things along, but the kind that actually feeds bacteria. That is why apple fiber and a fiber called FOS are in the same scoop. Add bacteria with nothing to feed it and most of it simply passes through you.

That is job two. Almost no probiotic on the shelf comes with it.

Part03Or this one

Something to break that food down.

Plants keep the good stuff behind a tough wall. That wall is built to survive being eaten.

People do not make the tool that cuts it open. Cows do. We do not. So you can eat a big pile of greens and still only use a little of it. Enzymes are that tool. They cut food apart so your body can take it in. There are twelve in here, each one printed by name. Together all three support digestive health.* The lab report is posted with the date on it.

It has wheat in it, from the wheat grass. Read that before you buy.

The honest part

So what is the catch?

We will start with the worst one.

Part04

Yes, it tastes green.

This is why most tubs end up half full. So we will just say it.

It is sweet from stevia, not sugar. Fifteen calories a scoop. Most people say it tastes like berries. Some say sweet green tea. But read our one star reviews. You will find the word gritty. Some people never get past it, and we leave those reviews up.

Mix it in cold water, not warm. Drink it before it sits.

In their words

People who kept going.

Real reviews, printed whole. We picked them with a rule we wrote down first.

Everyone is different. These say how people use it, not what you should expect.

All of it is printed on the tub. We do not name other brands. We do not win every row.

Before you order

What people ask us.

What does it taste like?

It is sweet from stevia, not sugar. Fifteen calories a scoop. Most people say berry or sweet green tea. Some say gritty. You will find that word in our one star reviews. We leave them up. Mix it cold, not warm.

I already take a probiotic. Do I need this?

Maybe not. A probiotic covers one of the three jobs. This covers all three in one scoop. Put both labels side by side and see what yours already gives you. Or ask your doctor.

How do I skip or cancel?

In your account, any time. Skip it, move it, swap it or cancel it. No phone call. Cancelling stops every charge after it. A charge we already ran still ships. So cancel before your next date.

Does it have wheat or gluten?

Yes. It has wheat in it, from the wheat grass. Do not take it if wheat bothers you. Do not take it if you have celiac. This is on the label and at the bottom of this page too.

Can I take this with my medicine?

Ask your doctor first. Never stop your medicine to try a supplement. Bring the label with you. Every part and every amount is printed on it.

When will I feel something?

We will not give you a number of days. It is different for everyone. Anyone who gives you a number is guessing. We can tell you what is in the scoop and how much. That is on the label and in the lab report.

What else is in the tub?

Eight blends in all. A big greens blend of thirteen whole foods. Then ones for immune, stress, focus, liver, heart and joints. Each one is named with its milligrams on the label. This page is about the gut one.

Is this the same as your gummies?

No. Same idea, different mix. The gummies are a strawberry chew with vitamins. This scoop is the one with the thirteen good bacteria and the twelve enzymes. Some people keep both. Scoop at home, gummies in the bag.

The law says we have to print the next part. We would print it anyway.
