The core nutrients in women's collagen peptide milk powder generally fall into three main categories: Beauty & Skin, Energy & Weight Management, and Digestion & Absorption.

Beauty & Skin Core (Main selling point)

Collagen Peptides – As small-molecule collagen, they are easily absorbed by the body, helping to maintain skin elasticity, improve roughness, and reduce dullness.
 
Vitamin C – Not only brightens the complexion and improves skin texture, but also acts as an essential "catalyst" for the body's natural collagen synthesis.
 
Vitamin E – A classic antioxidant that helps protect the skin from oxidative damage and keeps it smooth.
Energy & Weight Management (For body shape concerns)

L-Carnitine – A substance that supports fat metabolism; added to help the body convert energy more efficiently.
 
Zero Sucrose Formula – Most products use a low-calorie or zero-sucrose formula to reduce sugar intake.
Basic Nutrition & Absorption (Ensures efficient nutrient use)

Prebiotics + Probiotics (Dual support) – Probiotics regulate gut flora, while dietary fiber promotes bowel movement. Together, they create a healthy digestive environment for better absorption of collagen and other nutrients.
 
High Calcium & Iron 
High Calcium – Supports bone health.
Iron – Helps improve complexion and energy levels.
