What is Thryve?

Thryve consists of a two-part system for better digestive and intestinal health. You obtain a microbiome test kit from Thryve, complete the test, and return it to the company. After testing your stool sample, the staff at Thryve recommends customized probiotics to optimize your intestinal health.

Although Thryve is known for its microbiome tests and specialized probiotics, it also offers a line of probiotic supplements claiming specific health benefits. These include:

  • Endless Energy
  • Ketone Booster
  • Ultimate Immunity

Each of these products claims to contain special bacterial strains.

Does Thryve work?

  • Nutrients — “Although antioxidant activity was higher in black and green kombucha compared to rooibos, the latter showed an important effect on the recovery of oxidative damage on fibroblast cell lines against oxidative stress.”
  • Antioxidants — “Therefore, the choice of other tea types than the traditionally used black tea and the subjection of these tea types to fermentation seems to be beneficial in terms of the healthy properties of kombucha.”
  • Nutrients – “Both fiber-enriched supplements tested herein seem to be beneficial to gut-health, although differently.”

Who Makes It

Who Makes Thryve?

Currently, the CEO and Co-Founder of Thryve is Richard Lin. His passion for the company started after taking antibiotics and becoming ill. Apparently, the experience jump-started his need to develop quality probiotics that meet the needs of different individuals.

Thryve Customer Testimonials

Thryve Claims

Thryve states that it uses a microbiome test kit and ships it to the customer to analyze their stool to determine the microorganisms in their intestinal tract and stomach. Microbes help us break down the food we digest.

Thryve claims we each have a different composition of microbes within our bodies, and the test kit analysis determines which the customer has. These tests can do this by examining 16 rRNAs in the DNA.

The company provides an extensive report with up-to-date research on the microbes present in human stomachs and those found in the customer’s intestinal tract. Its FAQ and blog stress that the test and its results are not meant as a medical diagnosis and should be used in conjunction with a diagnosis and treatment from one’s general practitioner or specialist.

The report includes a custom list of foods best suited to their diet based upon their stomach/intestinal microbiome. The company recommends probiotics from their line and custom mixes based on the customer’s microbiome testing results.


Thryve Ingredients

Thryve creates its kefir and kombucha for use in its ketone booster, immunity supplement, and energy supplement. Its website collects its own strains of kefir and human probiotic sample and works with a lab to craft the custom mixes.

Outside of the custom probiotic supplements, Thryve offers a couple of different specific products. These supplements – Endless Energy, Ketone Booster, and Ultimate Immunity – contain specific strains to boost health benefits.

All of the supplements also contain inulin.


Does Thryve Work?

Thryve supplements are derived from kefir and human samples.

Similar to milk in consistency, kefir’s yeast and bacteria differ depending on the ingredient mix. According to an article in Nutritional Research Review, the nutritional benefits of the kefir vary by the milk composition, microbiology of the grains, temperature at which it is fermented, and length of time for fermentation, as well as the storage conditions.

Kombucha is a fermented drink consisting of black or green tea blended with yeast and sugar. It can be made at home or purchased over the counter.
A scientific review article published in Annual Epidemiology found the substance to have some health benefits, though only animal test subjects were used in the study.

Additionally, according to the Journal of Nutrition, consuming fermented foods can modify the microbiota in the intestines and stomachs.

Weight Loss

Thryve and Weight Loss

According to a research article published in the European Journal of Nutrition, kefir produces similar weight loss as low-fat dairy milk used in a dairy-rich but non-energy-restricted diet. This similarity was observed in overweight and obese premenopausal women. The eight-week study observed 75 participants, of which 58 completed the full study.

Unfortunately, human studies have yet to be conducted on kombucha and its effects on weight loss.

Side Effects

Thryve Side Effects

The site reports only one potential side effect. You might experience more frequent stool movements while taking the supplements. Once you stop taking the supplements, the stool function returns to normal.

Additionally, probiotics are known for causing some side effects when you start taking them, like:

  • Bloating
  • Diarrhea
  • Constipation
  • Abdominal Pain

Although these effects should be mild, if they become more bothersome, make sure to consult with your doctor.


How to Use Thryve

Three different products exist in the Thryve family. Each supplement gets customized according to the results of the individual’s microbiome test kit results.
While the dosage typically remains one pill per day, each mix’s ingredients’ levels will differ according to the microbiome results.


Cost and Where to Buy

The Thryve supplements vary in price. Endless Energy, Ketone Booster, and Ultimate Immunity all cost $39. If you choose a subscription, you only have to pay $35.10 each.

The Thryve gut health program costs $100. However, to actually receive a personalized product, you also have to sign up for a subscription.

Bottom Line

The Bottom Line on Thryve Results

Thryve is a unique brand. We love that they offer such detailed information about the tester’s gut health and created personalized probiotics. Even though a good probiotic can be a great addition to a diet, it isn’t the answer to weight loss.

When it comes to weight loss, it might be best to turn to a comprehensive program backed by real clinical studies like Noom.

We love that Noom offers personalized meal plans, health coaches, educational lessons, food-tracking tools, and more. For a limited time, we’re offering all Dietspotlight readers a free trial offer of Noom.
