NAD+ 500mg
21-Day Lead

NAD+ 500mg

NAD+ (nicotinamide adenine dinucleotide) is a vital coenzyme present in all living cells, participating in over 500 enzymatic reactions essential for energy metabolism and cellular function. It supports DNA repair and gene regulation by serving as a substrate for sirtuins and PARPs, enzymes that regulate aging, stress resistance, and genomic stability.

SEMA 15mg
21-Day Lead

SEMA 15mg

Semaglutide is a synthetic GLP-1 receptor agonist that mimics the naturally occurring gut hormone glucagon-like peptide-1 to regulate appetite and metabolism. It strengthens satiety signals, slows gastric emptying, improves insulin secretion, and modulates gut-brain communication to support weight loss and glycemic control.
