The current study is part of a larger project called the CalGo-project. The overall purpose of the study is to use bone meal from salmon to promote skeletal health. Specifically, the effect of salmon bone meal on bone mass density among perimenopausal women (age ≥ 50 years) with osteopenia is investigated over a time period of 2 years. Salmon bone meal is composed of a natural microcrystalline hydroxyapatite form of calcium and phosphorus, collagen type 2. Past literature on mammalian sources of bone meal has indicated that this form of calcium is superior in terms of preserving bone mass density compared to traditional calcium supplements. Preserving bone mass is essential to reduce the risk of future fragility fractures. Osteopenia is a condition of reduced bone mass density and bone quality which can indicate the later onset of clinical osteoporosis. Both are conditions associated with a significant risk of fragility fractures, which are a major global health burden.~Bone mass density is measured using dual-energy X-ray absorptiometry. Markers of bone formation P1NP and CTX-1 will be measured in serum samples of participants. 100 potential participants will be screened for eligibility. Participants who meet the eligibility criteria will be randomized in a double-blind manner to receive 4 capsules daily of salmon bone meal enriched with Vitamin D3 per capsule.
The purpose of this study is to evaluate the efficacy of salmon bone meal in preventing bone loss among perimenopausal women with reduced bone mass density.
