What is KeraBiotics?
KeraBiotics is a topical liquid formula for your toenails and the skin around them. Instead of harsh chemicals, it’s built around a simple idea: your skin and nails are home to a community of microbes, and keeping the “good” bacteria strong helps create a healthier-looking environment for your feet.*
Each bottle combines four well-known probiotic strains (Lactobacillus paracasei, rhamnosus and acidophilus, plus Bifidobacterium lactis) with copper gluconate, cosmetic peptides and soothing aloe, cucumber and glycerin. The makers say the formula was inspired by the barefoot traditions of an Amazonian tribe known for remarkably healthy feet.*
According to the official site, KeraBiotics is non-GMO, stimulant-free and easy to use. It’s sold only through its official website, with secure checkout by BuyGoods.

✓ Want clearer, healthier-looking toenails*
✓ Have dry, rough skin around your nails
✓ Like the idea of probiotic, microbiome-friendly care
✓ Prefer a simple daily foot-care routine
✓ Want to try it with a 60-day guarantee

How to use KeraBiotics
1. Wash and fully dry your feet.
2. Apply the drops to your toenails and the skin around them, following the bottle directions.
3. Let it dry before putting on socks or shoes.
4. Use it daily and keep feet clean and dry; give it around 3 months.
Is KeraBiotics safe?
KeraBiotics is applied to the outside of the nails and skin, and its ingredients (probiotics, aloe, glycerin, cucumber, peptides and copper) are common in skincare. As with any new topical product, patch-test a small area first and stop if you notice redness, itching or irritation. Avoid broken or open skin.
See a doctor or podiatrist if your nails are thick, painful, crumbling or spreading to other nails, and always check with your doctor first if you have diabetes or poor circulation, since foot problems need closer care.
KeraBiotics is a cosmetic foot-care product. It isn’t meant to diagnose or treat any medical condition, including fungal infections.
KeraBiotics FAQs
What is KeraBiotics?
KeraBiotics is a topical liquid for toenails and the surrounding skin. It combines four probiotic strains with copper gluconate, peptides, aloe, cucumber and glycerin to support healthy-looking nails and feet.*
Is it a capsule or a topical?
It’s topical. You apply the drops directly to your nails and the skin around them; you don’t swallow it.
How do I use KeraBiotics?
Apply it to clean, dry toenails and the surrounding skin as directed on the bottle, let it dry, and use it daily.
How long until I see a difference?
Toenails grow slowly, so changes take time. The company suggests using it for at least 3 months, which is why multi-bottle packs are popular.
Does KeraBiotics treat nail fungus?
No product sold as a cosmetic can claim to treat an infection. KeraBiotics is designed to support healthy-looking nails and skin. If you suspect a fungal infection, see a doctor or podiatrist.
How much does KeraBiotics cost?
One bottle is $69, three bottles are $59 each ($177) and six bottles are $49 each ($294). Every US order ships free, and the 3- and 6-bottle packs include two free guides.
Is there a money-back guarantee?
Yes. You have 60 days from delivery to request a refund, and opened or empty bottles are accepted. You pay return shipping.
Where can I buy KeraBiotics?
Only on the official website, with secure checkout by BuyGoods. It isn’t sold on Amazon or in stores.
