Promotes Digestive Balance Flora-Key provides five powerful probiotic strains to replenish beneficial bacteria, helping to ease bloating, gas, and digestive discomfort.
Supports a Strong Immune System A healthy gut microbiome is the foundation of strong immunity. Flora-Key nourishes your body with probiotics and prebiotics to help you stay resilient.
Enhances Skin & Detoxification By supporting gut health, Flora-Key helps your body detox naturally, leading to clearer, healthier skin and a radiant glow.
Easy-to-Use Formula With a mild, slightly sweet taste, Flora-Key dissolves easily in water, smoothies, or any unheated food or beverage—making gut health simple and convenient.
A balanced gut is key to optimal health, but factors like antibiotics, sugar, stress, and environmental toxins can disrupt the delicate balance of beneficial bacteria. When this happens, digestion, immunity, and overall well-being can suffer—allowing harmful microbes to thrive while beneficial bacteria diminish.
Flora-Key's probiotic and prebiotic blend works to feed, strengthen, and transport good bacteria where it's needed most, crowding out harmful toxins and pathogens that can interfere with digestion, immunity, and even weight loss.

Why do probiotics matter?
A strong digestive system relies on a healthy population of beneficial bacteria to break down food, absorb nutrients, and keep harmful microbes in check. Probiotics help maintain this balance, while prebiotics act as fuel to support their growth. Supplementing with a daily probiotic powder like Flora-Key may also help synthesize key vitamins and minerals, ensuring your body gets the nourishment it needs for long-term wellness.
Who should take Flora-Key?
Anyone looking to support their digestive health or strengthen their immune system can benefit from Flora-Key. It’s especially helpful for those who have taken antibiotics, experience bloating and digestive issues, or just want an easy way to maintain gut balance.
How is Flora-Key different from other probiotics?
Unlike many probiotic supplements that only contain bacteria, Flora-Key combines both probiotics and a prebiotic for more complete gut support. It delivers 20 billion CFUs—an optimal amount that supports digestive and immune health without overwhelming the system. Higher CFU counts found in some products can actually trigger autoimmune responses in sensitive individuals, so Flora-Key strikes a healthy balance. Plus, its mild-tasting powder dissolves easily in food or drinks for better absorption, no capsules needed!
Can kids take Flora-Key?
Yes! Flora-Key is safe for both adults and children, making it an easy way to support gut health and immune function for the whole family. Adults can take one scoop daily mixed into 4–6 ounces of water. For children weighing 40–80 pounds, use half the adult dose. Flora-Key is not recommended for children under 40 pounds unless advised by a healthcare professional.
How should I take Flora-Key?
Simply mix a scoop into water, juice, smoothies, yogurt, or any unheated food or beverage. It blends well into a variety of foods and drinks for an easy daily gut health boost.
"I've used other probiotics over the years. Flora-Key by far is the best! It help keep my digestive tract healthy. I simply add it daily to a shake or just mixed in water. As suggested by Ann Louise, it also makes a good sweetener substitute."– Joyce L.
"I've tried probiotics over the years but never noticed a difference until I took this one. My fingernails always had ridges which is indicative of poor digestion. After taking this for several weeks I noticed my nails are smooth! I cannot believe it. Uni Key offers great products! Thank you!"– Karen
"Been using this product for years and it’s amazing. Not only do I love it, but it also kept me going when I was battling cancer. My doctors often asked what is keeping me well, what am I taking? Flora-Key!"– Julie A.
"Flora-Key is truly one of my daily essentials because it goes far beyond your typical probiotic. It's a naturally sweet, easy-to-use powder that blends effortlessly into water, smoothies, or no-heat recipes, making it a joy to take. What sets it apart is the comprehensive support it offers: probiotics and a prebiotic working together to promote gut balance, boost immunity, and support detox—all without harsh stimulants or synthetic fillers.
With five carefully selected strains of beneficial bacteria, Flora-Key helps reduce bloating, supports smooth elimination, and promotes everything from skin clarity to yeast and urinary balance. And because it's a powder, not a capsule, it absorbs quickly and efficiently, delivering results you can feel. Each scoop provides 20 billion CFUs—an ideal amount to nourish the gut without overwhelming the immune system. Some formulas with higher CFU counts may actually trigger autoimmune responses in sensitive individuals, so this balanced dose makes Flora-Key both gentle and effective.
As I always say, health begins in the gut—and Flora-Key is my daily go-to for maintaining that foundational balance. It's gentle enough for children, yet powerful enough for adults navigating stress, dietary changes, or immune challenges. No matter the season, Flora-Key is one of the simplest and most effective ways to support your gut health every day."

Nice taste
Thank you for your great feedback on Flora-Key, Judith. We are so glad to hear that you like it! Thanks for making UNI KEY a part of your health journey :)
Maybe too soon to tell. I mix it with my protein and collagen drink and take it most days.
After emergency surgery a couple of years ago for a bowel obstruction caused by scar tissue, I spent my “12 days of Christmas” in the hospital on IVs and heavy antibiotics.
When I finally got home, I knew my gut needed help—and Flora-Key came to my rescue. Within days, I felt lighter, less bloated, and more balanced. It truly brought my digestion back to life.
THANK YOU UNI KEY for this product! I never knew how much I needed it... until I did.
Thank you so much for sharing your experience with Flora-Key! We are so glad to hear that it was able to help you after your surgery and bring balance to your digestion. We appreciate you choosing UNI KEY to be a part of your wellness journey :)
Having tried various probiotics over the years, we have found that Flora-Key is the best. It helps keep our digestive tract healthy, and we find it easy to incorporate into the daily routine by adding it to a shake or simply mixing it with water. And as a plus, it is a good sweetener substitute!
Thank you so much for your great review! We’re thrilled to hear that Flora-Key has become a staple in your routine and is helping support your digestive health. Thank you for making UNI KEY a part of your health journey :)
Very light flavor, dissolves easily into cold or room temp liquid (I use a frother to get any clumps out). I take it with Mineral-Key in cran-water and feel good knowing I'm helping my gut!
Thanks for your support and great review on Flora-Key, Amanda! We are so happy to be part of your health journey :)
