Buyer Takeaway: The 2026 approval of oral GLP-1 pharmaceutical options means the "needle-free" positioning that defines this supplement category now has pharmaceutical competition it didn't have 18 months ago
It gets there by combining appetite control from GLP-1, an insulin boost from GIP, and energy burning from glucagon
