- The DehydraTECH formulation delivered measurable quantities of cannabidiol ("CBD") into blood in as little as 2 minutes;

- Lexaria's technology delivered more CBD to bloodstream in 15 minutes than conventional medium chain triglyceride ("MCT") oil based control formulation achieved in 60 minutes;

- The area under the curve ("AUC") for Lexaria's patented DehydraTECH formulation was 389% more than the MCT oil control formulation;

- Lexaria's DehydraTECH formulation delivers cannabinoids at industry-leading volumes and speed while effectively masking bitter flavor and aroma profiles.

Kelowna, British Columbia - May 15, 2019 - Lexaria Bioscience Corp. (OTCQX: LXRP) (CSE: LXX) (the "Company" or "Lexaria"), a drug delivery platform innovator, has proven in animal testing that Lexaria's DehydraTECHTM technology delivers cannabinoids to the bloodstream much more quickly and effectively than conventional industry cannabinoid edible formulation designs that often combine cannabinoids with MCT oils such as coconut oil.

BACKGROUND

On March 20, 2019, Lexaria announced it had commenced a series of animal studies with multiple objectives, including gaining a better understanding of how edible forms of cannabinoids enter the bloodstream. Initial results from these studies are now available and Lexaria expects to make a series of announcements disclosing results as they are processed.

In the first animal study results announced today, Lexaria compared its standard DehydraTECH formulation that combines cannabinoids with long-chain fatty acids ("LCFA") using Lexaria's patented dehydration processing technique to a concentration-matched formulation utilizing coconut oil which is a commonly used medium chain triglyceride ("MCT") oil in the cannabis edibles industry.

MCT oils are commonly used by many firms making and selling cannabis edibles throughout North America. Lexaria has consistently postulated that the use of MCT oil in edibles is less effective for purposes of cannabinoid delivery optimization than its patented DehydraTECH LCFA formulations. Although these studies tested only for CBD delivery, Lexaria has every reason to believe that virtually identical results would have been achieved if THC was instead the cannabinoid under examination, consistent with subjective human clinical studies Lexaria's partners have conducted with edible THC products.

TEST RESULTS

In each arm of the Lexaria animal studies, 10 male Sprague-Dawley rats were administered CBD at 25mg per kg of bodyweight. Delivery of CBD into the bloodstream was monitored over a 60-minute duration. Certain data are not being disclosed at this time for reasons of intellectual property protection.

Above: Lexaria LCFA Formulation vs. MCT Formulation

--At 2 minutes DehydraTECH's LCFA formulation delivered measurable CBD in blood, compared to no measurable CBD in blood until 6 minutes and onwards for the MCT oil formulation.

--At 15 minutes DehydraTECH's LCFA formulation achieved a CBD blood concentration level that was 475% more than the MCT oil formulation; and, the DehydraTECH LCFA formulation CBD blood levels reached at 15 minutes were greater than the CBD blood levels reached by the MCT oil formulation at any time point during the 60-minute evaluation.

--At 60 minutes DehydraTECH's LCFA formulation achieved a CBD blood concentration level of 319% more than the MCT oil formulation.

--Over the entire 60-minute study, the animals that received the standard DehydraTECH LCFA formulation achieved an average maximum CBD blood concentration level that was 334% more than the average maximum blood concentration level of the animals that received the MCT oil formulation (p<0.0021).

--Over the entire 60-minute study, the area under the curve (AUC) (total quantity of CBD delivered) for the Lexaria DehydraTECH LCFA formulation was 389% more than the MCT oil formulation (p<0.0011).

Lexaria also tested for brain tissue concentrations to quantify 8-hour CBD delivery from the DehydraTECH-enabled LCFA formulation compared to the MCT oil formulation and DehydraTECH's LCFA formulation outperformed the MCT oil formulation by 246%. As was previously demonstrated through two series of animal tests delivering nicotine in 2018, Lexaria's DehydraTECH continues to deliver a drug both to the bloodstream and across the blood-brain-barrier ("BBB") more effectively than industry standards. More efficient delivery into bloodstream and across the BBB can lead to increased consumer satisfaction and results utilizing lower drug dosage quantities.

CONCLUSION

The cannabis edibles industry has partially embraced the use of MCT oils such as coconut oils as a co-ingredient in edible products, mostly because of the luxurious taste and mouth-feel of coconut oil. Lexaria's head-to-head animal absorption study has proven that coconut oil formulations deliver cannabinoids into animal bloodstreams very poorly at only about one-quarter the rate of the patented Lexaria LCFA formulation. Lexaria's DehydraTECH technology was also shown to deliver CBD considerably more quickly than MCT oil formulations.

Lexaria's patented DehydraTECH technology has been used by licensees in the cannabis industry for three years and has been proven to effectively mask the bitter flavors and aromas of cannabis without the use of MCT oils, artificial chemical masking agents, or additional flavoring agents or sweeteners. DehydraTECH's LCFA formulation is capable of delivering cannabinoids at industry-leading volumes and speed and simultaneously offering the most advanced flavor and aroma profile masking techniques in the industry.

About Lexaria
