Hydrolyzed collagen for skin, joint & bone support.
- Typical dose
- 5-15g Daily
- Route
- Oral
- Cycle length
- Ongoing
- Evidence
- Limited human data
Mechanism
How it works
Collagen peptides are like LEGO bricks for your connective tissue — your body breaks them down and reassembles them where structural support is needed.
Hydrolyzed collagen provides amino acids (proline, glycine, hydroxyproline) that stimulate fibroblast activity and extracellular matrix synthesis.

In depth
Full profile
What it does
Improved skin, reduced joint pain, stronger hair/nails, better bone density.
How it works
Collagen peptides are like LEGO bricks for your connective tissue — your body breaks them down and reassembles them where structural support is needed.
Absorbed as di/tripeptides that stimulate collagen-producing cells (fibroblasts, chondrocytes, osteoblasts).
What to expect
Skin effects at 4-8 weeks; joint effects at 8-12 weeks.
- Weeks 2-4: Improved skin hydration.
- Weeks 4-8: Reduced wrinkle depth and joint pain.
- Weeks 8-12: Stronger nails and hair.
Good to know
- Choose Type I & III for skin/hair; Type II for joints
- Dissolve in hot liquid
- Start with 5g/day
Staying safe
- Mild bloating (rare)
- Aftertaste (unflavored powder)
Avoid if you have:
- Fish allergy (marine collagen)
- Shellfish allergy (some marine sources)
- Egg allergy (some sources)

Qué hace
Piel mejorada, reducción del dolor articular, cabello y uñas más fuertes, mayor densidad ósea.
Cómo funciona
Los péptidos de colágeno son como ladrillos LEGO para tu tejido conectivo: tu cuerpo los descompone y los reensambla donde se necesita soporte estructural.
Se absorbe como di/tripéptidos que estimulan las células productoras de colágeno (fibroblastos, condrocitos, osteoblastos).
Qué esperar
Efectos en la piel a las 4-8 semanas; efectos en las articulaciones a las 8-12 semanas.
- Semanas 2-4: Mejora de la hidratación de la piel.
- Semanas 4-8: Reducción de la profundidad de arrugas y dolor articular.
- Semanas 8-12: Uñas y cabello más fuertes.
Bueno saber
- Elige Tipo I y III para piel y cabello; Tipo II para articulaciones
- Disolver en líquido caliente
- Comenzar con 5g/día
Manteniéndose seguro
- Hinchazón leve (rara)
- Sabor residual (polvo sin sabor)
Evitar si tienes:
- Alergia al pescado (colágeno marino)
- Alergia a los mariscos (algunas fuentes marinas)
- Alergia al huevo (algunas fuentes)
Mecanismo de acción
El colágeno hidrolizado proporciona aminoácidos (prolina, glicina, hidroxiprolina) que estimulan la actividad de los fibroblastos y la síntesis de la matriz extracelular.
Se absorbe como di/tripéptidos que estimulan las células productoras de colágeno (fibroblastos, condrocitos, osteoblastos).
Farmacodinamia
