Try it Yourself

Our respiratory-specific proprietary probiotic blend contains three strains, Lactiplantibacillus plantarum RSB11™, Lactobacillus acidophilus RSB21™, and Lacticaseibacillus rhamnosus RSB13™, which work together to target the gut-lung axis.*

Turmeric is a product of the Curcuma longa plant, which has been celebrated for its health-promoting properties for millennia. Its respiratory uses are well-documented in the Ayurvedic tradition. More recently, scientists have put this ancient botanical under the microscope to explore its potential benefits for lung health.*

Ocimum tenuiflorum, commonly known as holy basil or tulsi, is also a rockstar of the Ayurvedic tradition, historically used to support a healthy immune system. Scientific inquiry suggests this ancient herb plays a role in healthy immune response.*

Vasaka, also known as Adhatoda vasica or malabar nut, is a popular herb for respiratory support in the Ayurvedic and Unani traditions. More recently, scientists have isolated two key alkaloids, vasicine and vasicinone, in vasaka leaf to better understand this bioactive botanical and how it supports easy breathing.*

Frequently Asked Questions

Anyone 18+ who wants to prioritize their gut, lung, and immune health!

While people often report gut health benefits as early as their first week, systemic benefits of probiotics can take longer.*

Some of our customers report breathing benefits within 6 days, others after 60. This variability can be attributed to a number of factors, including the importance of continuous daily use and the reality that some of us constantly think about our lungs while others breathe without much thought.
