Ingredients

What's Inside Osterro?

Each ingredient was selected to support different aspects of bone health during GLP-1 use, including bone mineral density, calcium utilization, collagen structure, skeletal integrity, and connective tissue support. When combined in carefully considered dosages, they create a comprehensive system designed to support long-term bone health and structural resilience.

Below is a complete breakdown of every ingredient in Osterro, why each one matters, and how they work together to support bone strength during GLP-1 use.

Calcium (from KoAct® Collagen Chelate)

KoAct® Calcium Collagen Chelate is a clinically studied form of calcium shown to help support bone mineral density, collagen integration, and skeletal strength beyond traditional calcium supplements. Its effects on bone preservation and bone matrix integrity have been supported in this clinical osteopenia study.

Eggshell Membrane (NEM®)

NEM® is a natural source of collagen, glycosaminoglycans, and structural proteins that help support connective tissue integrity, joint comfort, and healthy cartilage function. Its role in supporting mobility and structural health has been demonstrated in multiple clinical joint health studies.

Boron

Boron is a trace mineral involved in bone metabolism, calcium balance, and vitamin D activity. Research suggests it may help support bone mineral density and skeletal strength by influencing mineral utilization and osteoblast function, as demonstrated in this osteoporosis and boron review.

Silicon

Silicon is a trace mineral involved in collagen synthesis and bone matrix formation, helping support skeletal structure, connective tissue integrity, and healthy mineralization. Its relationship with bone density and skeletal health was highlighted in this published bone health study.

L-Lysine HCl

L-Lysine is an essential amino acid involved in collagen formation and calcium absorption, both of which play important roles in maintaining healthy bone structure and connective tissue integrity. Its effects on calcium utilization and skeletal maintenance were explored in this published lysine metabolism study.

Vitamin K2 (MK-7)

Vitamin K2 as MK-7 plays a critical role in directing calcium into bones while supporting osteocalcin activation and healthy bone mineralization. Its long-term effects on bone strength and vertebral integrity were demonstrated in this 3-year MK-7 clinical trial.

Vitamin D3

Vitamin D3 plays a central role in calcium absorption, bone mineralization, and skeletal maintenance by helping regulate calcium and phosphorus balance throughout the body. Its importance in maintaining bone density and reducing skeletal deterioration was highlighted in this vitamin D and fracture prevention study.

Magnesium

Magnesium is an essential mineral involved in bone mineralization, calcium regulation, and vitamin D metabolism, all of which contribute to maintaining skeletal strength and structural integrity. Its relationship with bone density and osteoporosis risk was examined in this magnesium intake and bone density study.

Vitamin C

Vitamin C plays a critical role in collagen synthesis and connective tissue formation, both of which are essential for maintaining strong, resilient bone structure. Its association with improved bone density and reduced fracture risk was discussed in this vitamin C and osteoporosis analysis.

Hyaluronic Acid

Hyaluronic acid is a naturally occurring compound involved in connective tissue hydration, cartilage resilience, and extracellular matrix structure. Its role in supporting osteogenesis and tissue regeneration was explored in this hyaluronic acid osteogenesis study.
