Biscuit breakthrough? pea protein and vitamin d may slow muscle aging
NCT ID NCT07356440
First seen Jun 27, 2026 · Last updated Jul 28, 2026 · Updated 2 times
Summary
This study looks at whether eating special biscuits made with pea protein and taking vitamin D can help prevent sarcopenia—the age-related loss of muscle mass and strength. Researchers will recruit 74 adults aged 65-80 with early signs of muscle loss. For 12 weeks, half will eat the protein biscuits and take vitamin D drops, while the other half get plain biscuits and placebo drops. The goal is to see if this simple diet change can slow muscle decline and improve quality of life.

Inclusion Criteria Given the multifactorial, heterogeneous nature of sarcopenia, volunteers will be enrolled if they meet at least one of the following three diagnostic criteria : * Ishii equation values: patients with a score ≥105 for males and ≥120 for females will be included. The Ishii screening test is a widely used method that estimates the probability of sarcopenia using a score derived from an equation based on three variables: age, grip strength, and calf circumference. * Appendicular skeletal muscle mass index (ASMI): \<7.0 kg/m2 for males and \<5.5 kg/m2 for females. * Short physical performance battery score ≤8 In addition, the following inclusion criteria are considered: * Body mass index ≥19 \<30 kg/m2 * Ability to act Exclusion criteria * Age \<65 or \>80 years; * Body mass index \<19 or ≥30 kg/m²; * Diagnosis of cancer within the previous five years; * Regular intake of vitamin D supplements; * Dysphagia and difficulty chewing; * Allergy or other intolerances to gluten; * Allergy to eggs; * Intestinal disorders (Crohn's disease, ulcerative colitis, bacterial overgrowth syndrome, constipation, coeliac disease, irritable bowel syndrome) that could affect the gut microbiota; * Pacemaker recipients; * Acute inflammation (CRP \>10 mg/L); * Anaemia (haemoglobin \<13 g/dL in men; \<12 g/dL in women); * Renal failure (glomerular filtration rate (GFR) \>45 mL/min/1.73 m²); * Chronic liver disease (transaminases \< 40 IU in men, \< 35 IU/L in women); * Inability to act
