Results: Studies with Zeebo placebo pills reveal that even when you know you’re taking a placebo, you can still experience the placebo effect. Known as an honest placebo, this phenomenon has been shown to apply to a wide range of symptoms, giving you the option to self-administer for genuine relief.

Low risk: Unlike medications that carry some risk from active ingredients, honest placebos like Zeebo® do not have such side effects. This allows you to safely experiment and discover if you can harness the placebo effect for yourself.

Publications: The benefits of honest placebos are extensive, addressing various symptoms. Their impressive potential has been highlighted in peer-reviewed publications such as The Journal for Pain, American Family Physician, and Nature. Several of these studies have been conducted with Zeebo. The subjects knew they were taking Zeebo placebo pills.

Quality: We ensure our placebo pills and packaging meet the highest quality standards. Each bottle is carefully packed and sealed, making it convenient and easy to use.

Short-Term Low Back Pain Relief with Placebo

“Over three weeks, patients with long-term low back pain who knowingly took placebo twice a day reported less pain and disability than those continuing with treatment as usual. This is not the only study to show the benefit of placebo. Whether the benefit persists is not known. A nonprescription placebo (Zeebo) is available, or pharmacists can prepare placebo capsules. (Level of Evidence = 2b)”

What are Zeebo Retail Customers saying


I have to admit that … I really didn’t believe in Zeebo placebo pills… So after a few days I was surprised to realize that it was actually working for me!!


I used Zeebo to draw my attention to healthy eating habits. Taking the pill and logging it in the app distracted me from mindless eating.


A big part of ridding ourselves of our ailments is to take control over them. Zeebo is kind of weird, but in a mysterious way, empowering.


I take Zeebo placebo pills for occasional headaches. Several times now I took a Zeebo and that was all that I needed.

FAQ – Honest, Pure, Branded Placebo Pills

Why Honest?

Open or honest placebos are a new concept. A person who takes an honest placebo pill knows it only contains inert ingredients. There is no deceit involved. There are several studies published on taking honest placebo in a safe setting.

Why Pure?

Historically, sugar has often been used as a filler for placebos (sugar-pills). However, sugar is somewhat of an active ingredient, so it can cause problems for people with, for example, diabetes. Fillers in pure placebo capsules are inert—they pass through the body without much interaction.

Why Branded?

Today, brands play a tremendous role in the marketing of products and services. Brands convey meaning that reaches the subconscious. Branded Zeebo placebo pills harvest the power of modern marketing to promote well-being.  Our branded Zeebo Relief pills come in the Zeebo brand color in light blue and white, with the Zeebo logo printed on the white section of the capsule. Zeebo branded capsules are unique. Zeebo is The Healing Brand.
