Can a nutritional shake keep older adults strong and sharp?
NCT ID NCT07815158
First seen Sep 11, 2026 · Last updated Sep 11, 2026
Summary
Researchers are testing a daily nutritional powder to see if it can improve physical function, thinking, and metabolic health in people aged 65 and older. The formula contains proteins, vitamins, minerals, and plant compounds. For 12 weeks, participants will drink either the formula or a placebo powder, and researchers will measure changes in walking speed, grip strength, memory, and blood markers. The goal is to learn whether this supplement can help maintain independence and health in older adults.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a multi-component nutritional formula containing proteins, vitamins, minerals, and plant extracts
- What this could lead to
- If the formula helps, it could offer a simple dietary way to support muscle strength, mobility, and thinking in older adults.
- What could go wrong
- This is a small, 12-week study. Any benefits may be modest or fade, and the formula might not work better than a placebo. Some people may experience digestive discomfort.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Age 65 years and older. 2. Intact consciousness and cognitive ability to understand and cooperate with the study protocol. 3. Capable of oral ingestion and self-administration of the study formula/placebo. 4. Meets at least one of the following priority recruitment criteria: 1. Screened positive for decline in at least one WHO ICOPE intrinsic capacity domain (locomotion, vitality, cognition, psychology, vision, or hearing). 2. Sarcopenia risk based on AWGS 2019 criteria: low handgrip strength (\<28 kg for men; \<18 kg for women), slow 6-meter gait speed (\<1.0 m/s), or Short Physical Performance Battery (SPPB) score ≤ 9. 5. Ability to attend scheduled hospital outpatient visits at baseline (Week 0) and Week 12. 6. Willing and able to provide written informed consent. Exclusion Criteria: 1. Severe hepatic impairment (GPT/ALT \> 3 times the upper limit of normal, or a confirmed diagnosis of liver cirrhosis). 2. Severe renal impairment (serum creatinine ≥ 2.0 mg/dL, eGFR \< 30 mL/min/1.73m², or a confirmed history of renal failure, chronic kidney disease, uremia, or dialysis). 3. Confirmed clinical diagnosis of dementia. 4. Active malignant neoplasms currently undergoing active oncological therapy (chemotherapy, radiotherapy, or targeted therapy). 5. Current use of oral anticoagulant medication (Warfarin) due to potential interactions with fish oil and vitamin K2. 6. Known allergy or hypersensitivity to any ingredient of the study product (dairy, soy, or fish sources). 7. High-dose supplementation with whey protein, fish oil, or botanical extracts within the past 3 months. 8. Presence of an active middle-ear implant or cochlear implant (to eliminate confounding factors during hearing assessments).
