Lactobacillus Rhamnosus is one of the most studied strains of probiotics — beneficial microorganisms naturally found in fermented foods and some supplements. Here's a closer look at what this strain is, where it's found, and what current research says about its possible role in skin and gut wellness.

Key Takeaways
- Lactobacillus Rhamnosus is a well-studied strain within the Lactobacillus genus of probiotic bacteria.
- It's able to survive both acidic and more neutral environments in the body, which is part of why it's a common choice in probiotic supplements.
- Researchers continue to study how probiotics like L. Rhamnosus may relate to the skin's microbiome and barrier function — this research is ongoing and doesn't establish that it treats any skin condition.
- The skin and gut each host their own microbial communities, and scientists are exploring possible connections between them (the gut-skin axis).*
- As with any supplement, it's worth checking with a healthcare provider before starting one, especially if you have an underlying health condition or take medication.
What Is Lactobacillus Rhamnosus?
Lactobacillus Rhamnosus belongs to the Lactobacillus genus, a group of bacteria that produce lactase — an enzyme that breaks down lactose, the sugar found in most dairy products. A byproduct of this process is lactic acid.
One reason L. Rhamnosus is a common choice in probiotic supplements is its adaptability: it's able to survive in a range of conditions in the body, from the more acidic environment of the stomach to the more neutral environment of the intestines.
Skin, Its Microbiome, and Probiotics
The skin is the body's largest organ and home to millions of bacteria, yeasts, and fungi that make up its microbiome. Researchers are interested in how keeping this community balanced may relate to the skin's overall appearance and condition.
Probiotic strains like L. Rhamnosus are being studied for their potential role in supporting this balance, though this research is still developing and doesn't establish that taking a probiotic treats, cures, or prevents acne or any other skin condition.*
Probiotics and the Skin Barrier
The skin barrier is the outermost layer of skin, and it plays a role in retaining moisture and limiting exposure to outside irritants. Keeping this barrier healthy is generally considered a helpful part of an overall skincare routine.
Some early research has looked at L. Rhamnosus in relation to skin barrier support. As with other probiotic research in this area, findings are preliminary and don't establish that any probiotic strain repairs or treats a compromised skin barrier.*
Supporting Gut Balance
Like the skin, the gut hosts its own large community of microorganisms. A balanced gut microbiome is generally considered important for digestive health, and probiotics such as L. Rhamnosus are commonly taken to help support that balance.
Researchers continue to explore whether and how gut health may connect to skin appearance through what's sometimes called the gut-skin axis. This is an active area of research, not an established treatment pathway.*
Choosing a Probiotic Supplement
If you're considering a probiotic supplement, it's worth taking the time to read labels closely — checking which strains are included, at what dose, and how the product is manufactured. Some supplements combine multiple strains, such as L. Rhamnosus alongside Lactobacillus Plantarum or Lactobacillus Acidophilus.
As always, checking in with a healthcare provider is a good idea, particularly if you're immunocompromised, pregnant or nursing, or take other medications.
