Myristoyl Pentapeptide-17 (keratin and skin renewal)
Most GLP-1 meds are once-weekly, and the needle is very small

Practical Application Start with protein and vegetables: Activates L-cells early, triggers initial GLP-1 release Add healthy fats: Sustains L-cell activation, slows gastric emptying Include complex carbohydrates: Provides sustained nutrient flow to L-cells Finish with fruit (optional): Final fiber and polyphenol boost Protein source: 25-30 grams (palm-sized portion) Non-starchy vegetables: 2-3 cups (fiber and volume) Healthy fat: 1-2 tablespoons olive oil or avocado Complex carbohydrate: -1 cup quinoa, sweet potato, or legumes Example L-Cell Optimizing Meals: Breakfast: Greek yogurt with berries, ground flaxseed, chopped walnuts, and a drizzle of honey Lunch: Grilled chicken over mixed greens with chickpeas, avocado, and olive oil dressing Dinner: Baked salmon with roasted Brussels sprouts and quinoa, side of sauerkraut Advanced Strategy: Time-Restricted Feeding The Science: L-cells demonstrate circadian rhythms in their GLP-1 secretion capacity

Glutathione and its precursors (such as cysteine peptides) are absorbed intestinally and distributed systemically [66], reaching dermal tissues to exert photoprotective and skin-lightening effects, particularly relevant for women concerned with age-related pigmentation changes [74, 75]
