Wellness Begins in the Gut!

The key to prime health is in your gut.

It's teeming with a staggering 100 trillion bacteria, collectively termed the gut microbiome. While some can be harmful, introducing the right probiotics can ensure the good ones thrive.

The state of your gut microbiome can determine various health outcomes, ranging from digestive efficiency to the strength of immunity and heart health. (1)

This is where Synbio Tonik comes in.

Like all of our products, we've pinpointed the dosage that will be most effective for real, tangible results.

You might be surprised to hear that less is more when it comes to prebiotic and probiotics

Probiotic Blend (5 billion CFU)

When it comes to probiotics, taking only what you need will give you the best results to avoid gastroentestinal bloating and upset.

Most over the counter probiotics contain lactobacillus that is easily destroyed by the gut, so we're picked tougher probiotic strains that can resist acidic environments.

How it works & supporting studies

Extremely resistant to the acidic environment of the stomach. Research shows this strain can improve constipation symptoms and regulate Intestinal gut flora.


L. plantarum KABP™-021

Shown to help eliminate bloating, cramping, and stomach upset, as well as promote healthy bowel elimination.


L. plantarum KABP™-023

Bifidobacterium lactis

How it works & supporting studies

Questions? We've got you covered

What makes Synbio Tonik better than other brands?

Our formula is a true synbiotic formula that includes live bacteria strains with ample prebiotic fiber that is not only essential for probiotics to thrive but contributes to your healthy dose of daily fiber.

Our prebiotc and probiotic powder is easily absorbed by simply mixing with powder and drinking.

Our mantra at Human Tonik is to focus on ingredients in the right clinically dosages, which often means focusing on fewer ingredients in the right amounts.

How long before I start to see positive results?

When you start taking a prebiotic-probiotic supplement there can be an adjustment period as your body gets used to the increased fiber and bacteria intake in your body. The good news is, this means our supplement is working!

Many customers will notice results within 7 days for differences in digestion and bowel movements, other results develop within a month.

For those experiencing occasional constipation or digestive upset, it may take slightly longer for the good bacteria to have a positive impact on their microbial balance.

Everyone is different and so we suggest taking for one month consistently to notice the best results.

Will the probiotic strains make it through the gut?

We followed a rigorous screening and testing process so that we could select only friendly gut bacteria strains that can withstand harsh acids and bile.

How do I take Synbio Tonik?

Taking Synbio Tonik is super easy, just mix one scoop (included in your JAR) of our pre and probiotic powder with cool water and drink.

Avoid mixing Synbio Tonik with hot beverages or hot food because it can damage the bacteria strains.

If you are going to drink it straight away you can mix Synbio Tonik with either Supergreen Tonik (berry flavor) or Red Tonik.

What does Synbio Tonik taste like?

When mixed with water it tastes of refreshing berry lemonade.

Why is Synbio Tonik not inside Supergreen Tonik?

Live bacteria strains are delicate and can become inert when mixed into a formula with lots of ingredients. This is the reason we decided to not include probiotics within our Supergreen Tonik formula.

We only choose ingredients that mix well together and have a proven health benefit.

Do I need to store Synbio Tonik in the fridge?

Yes we recommend storing Synbio Tonik in the fridge after opening. It’s best to store unopened JARs in a cool environment prior to use too.

I am not happy with Synbio Tonik can I get my money back?

Every order is covered by our 365-day money-back guarantee. If you’re not satisfied please reach out to our customer service team.

The Human
Behind The Tonik

Adam Wright was a competitive triathlete until Chronic Fatigue Syndrome (CFS) caused debilitating brain fog, muscle weakness and constant illness.

After unsuccessfully trying different greens & nutritional products that weren't scientifically dosed with an open-label policy, Adam knew he had to develop his own if he wanted to break the cycle of illness, recovery and illness again.
