Functional and Metabolic Effects of Fonte Fausta® Water on Bone and Muscle Health in Osteoporotic Patients

This study aims to determine the impact of Fonte Fausta® water on bone and muscle metabolism in patients with osteoporosis or osteopenia, with or without sarcopenia, over a 12-month period. The research follows ethical guidelines (Helsinki Declaration) and has been approved by the Ethics Committee of the University of Campania "Luigi Vanvitelli." All participants provided informed consent.

Study Design and Participants The study is a multicenter, triple-arm interventional clinical trial conducted at the University of Campania "Luigi Vanvitelli." Participants include individuals diagnosed with primary osteoporosis or osteopenia, with or without sarcopenia, based on clinical guidelines and the EWGSOP2 criteria. Osteoporosis is diagnosed by a BMD T-score ≤ -2.5 SD or the presence of a fragility fracture, while osteopenia is defined as a BMD T-score between -1 and -2.5 SD. Sarcopenia diagnosis is based on low muscle strength and low muscle mass.

Exclusion criteria

include secondary osteoporosis causes (e.g., chronic diseases, endocrine disorders, long-term corticosteroid use), psychiatric conditions affecting consent, and pregnancy or breastfeeding.

Study Groups and Randomization

Participants are divided into three primary groups:

Patients with osteoporosis/osteopenia and sarcopenia Patients with osteoporosis/osteopenia without sarcopenia A control group with non-osteometabolic conditions

Each group is further randomized into two subgroups:

One receiving Fonte Fausta® water One receiving natural mineral water Assessments and Evaluations

Participants undergo evaluations at three time points:

Baseline (T0) Six months (T6) Twelve months (T12)

Key assessments include:

Laboratory Tests: Blood and urine analyses to assess biochemical markers such as ALP, bone-specific ALP, PTH, 25(OH)D3, and CTX.

Bioimpedance Analysis (BIA): Measures body composition, including fat and muscle mass.

Physical and Nutritional Assessments: Includes questionnaires like the International Physical Activity Questionnaire, handgrip strength measurements, and the Mini Nutritional Assessment.

Bone Health and Fall Risk: DXA scans measure BMD, and the FRAX® algorithm estimates fracture risk.

Pain, Performance, and Quality of Life: Evaluations include the Short Physical Performance Battery (SPPB), Brief Pain Inventory (BPI), and quality of life questionnaires (EQ-5D-3L and EQ-VAS).

This study aims to determine whether Fonte Fausta® water offers functional and metabolic benefits for bone and muscle health, potentially improving quality of life and reducing fracture risk in osteoporotic and osteopenic patients.

Inclusion criteria
