What the 36.2 percent versus 24.8 percent study means
One frequently cited study found that sublingual delivery achieved bioavailability rates of 36.2 percent compared to 24.8 percent for oral administration of the same compound. This roughly 46 percent improvement from switching from oral swallowing to sublingua

- One frequently cited study found that sublingual delivery achieved bioavailability rates of 36.2 percent compared to 24.8 percent for oral administration of the same compound. This roughly 46 percent improvement from switching from oral swallowing to sublingual holding demonstrates the significance of bypassing first-pass metabolism and reducing gastrointestinal degradation. However, this study used a specific peptide formulation, and results vary across different compounds. The takeaway is not that every peptide achieves 36 percent sublingual bioavailability. The takeaway is that the sublingual route consistently outperforms oral swallowing, and the margin is clinically meaningful.
