NCT05661006

Brief Summary

The aim of this pilot study is to conduct a study on geriatric population in Slovenia (non-users of dietary supplements/medicines with vitamine D, vitamin B12 and protein) and assess deficiency of selected nutrients, and to investigate the efficiency of the innovative food supplement prototype in improving nutritional status of elderly adults.

Interventions

Use of food supplementDIETARY_SUPPLEMENT

On day 1 subjects start with intervention on prearranged day. First dosage of test product is consumed during day 1 between regular meals (not as meal substitute). In the following days: continuation of consumption of test product once per day until end of the intervention. Subjects are recording daily consumption of the product. Intervention diet recording during last week of intervention (days 49-56): 3x24h dietary records (two days during weekday, one weekend day). Intervention end on day 56 ±3 (fasted condition): Measuring S-25-OH-VitD, S-VitB12, S-protein, S-albumin, S-CRP Measuring body weight \& height Collecting data regarding the palatability of the product

Masking Details
Subjects will be randomized on the first day of Visit 1 using simple randomisation using ratio 1:1 between test and placebo group. After the general subject's health is checked (vital signs), subjects will be assigned Subject Number, which will be pre-randomised to correspond with one of interventions (test group, placebo group). To assure double blind approach, study products will be packed in neutral packaging, and pre-labelled with Subject Number (S-XXX) and instructions for use. Selected site will be provided enough product i.e. subject boxes with corresponding Subject Number to cover initially planned number of included subject.

Intervention Model
PARALLEL
Model Details: This was a randomized, parallel, double-blind, placebo-controlled study included healthy elderly adults (age \> 65 years) who tested study products. On screening visit, participants underwent measuring of body weight \& height, and blood collection for measuring S-25-OH-VitD, S-VitB12, S-protein, S-albumin, S-CRP. Duration of study intervention for individual participant 56 ± 3 days, with one week pre-intervention monitoring of food intake (3x 24-h dietary records). On day 1 of the intervention period, participants were randomised in a 1:1 ratio.
