Matt: 3 Reasons I Choose Biotic⁺

  1. Rooted in science.

    Our formula, made up of seven strains, is informed by 380+ studies.

  2. Made and trusted by experts.

    It's developed by leading scientists and dietitians and loved by health professionals.

  3. Proven to work.

    Third-party testing shows that Biotic⁺ delivers 50x more bacteria, alive and active, than alternative formats.*

*Compared with a leading liquid probiotic, leading greens powder and a probiotic with a standard capsule. Tested in fasted conditions.

Why your gut matters

Your gut is key to your everyday life. Work, family and friends, exercising, and everything in between. But modern life can disrupt your gut bacteria, taking a toll on your body and mind.

We believe your gut shouldn’t be the cost of existing. It should be the foundation for living.

The benefits

Live bacteria that go further.

SPB — Benefits
Microbial diversity

A third-party human (in vivo) study showed that our active bacteria increases microbial diversity in the colon, balancing the gut microbiome.

Immune health

Our probiotic blend includes zinc, which contributes to the protection of cells from oxidative stress and the normal function of the immune system.

Skin, hair, and nails

The zinc in Biotic⁺ contributes to the maintenance of normal hair, skin, and nails.

One capsule a day

All seven strains, along with zinc, are in every capsule.

At any time

We generally suggest taking it in the morning, but find a time that fits your schedule.

With or without food

No need to take anything else alongside your Biotic⁺, unless you want to.

No need to refrigerate

Keep it in a cool, dark place.

World's most studied strains. Fact.

Carefully selected by scientists and dietitians, the strains in Biotic⁺ are chosen to benefit you and are informed by over 380 studies. And we regularly invest in third-party testing to measure its real-life impact.

So you can trust what you’re putting in your body is proven to work.

Designed to survive

Most gut supplements fall short. The bacteria they contain often can’t survive the acidity of your stomach.

So here's the solution. Our delayed-release capsule and acid-resistant strains guarantee the majority of the bacteria reach your colon, alive and active, ready to get to work.
