Pilot Study of "Bottarga" Supplementation: A Little-known, Sustainable "Blue" Food
This pilot study aims to explore the potential benefits of consuming Greek bottarga (grey mullet fish roe) in individuals with at least one metabolic abnormality (low HDL cholesterol, high LDL cholesterol, high triglycerides, obesity, or HbA1c ≥ 5.7%) or a diagnosis of diabetes.
Before initiating the crossover randomized controlled trial (RCT), the investigators will conduct a preliminary dose-testing study in five adults with at least one metabolic abnormality. Participants will undergo clinical assessments before and after the dietary intervention to evaluate changes in metabolic health markers. Following this phase, the investigators will proceed with a randomized, controlled crossover trial involving 20 eligible adult participants. This main study phase will compare the metabolic effects of daily bottarga supplementation with those of a calorically matched dairy product over an 8-week intervention period, with a 2-week washout period between interventions.
The investigators anticipate that bottarga supplementation will improve lipid profiles, inflammation markers, and insulin resistance, thereby supporting the potential use of sustainable blue foods as part of a healthy diet.
Exclusion: Current use of illicit drugs (other than marijuana); Use of hormone therapy (except oral contraceptives); Use of any medications for diabetes (except metformin), dyslipidemia (except statins), or immunosuppression; Known allergies to fish, seafood, or any fish-derived products, including bottarga; Clinical evidence or history of hepatic or renal insufficiency; Immunodeficiency conditions; History of non-skin cancer; Current use of any supplements containing n-3 fatty acids; Pregnancy; Participation in other clinical research studies.
Adults aged 18-60 years; Residents of Massachusetts; Presence of at least one metabolic abnormality (low HDL cholesterol, elevated LDL cholesterol, elevated triglycerides, obesity, or HbA1c ≥ 5.7%) or a diagnosis of diabetes; Not pregnant; Willing to consume a nutritional supplement and comply with study procedures.
