What effect does repeated ingestion of kefir have on the gut microbiome and can this positively influence sleep performance (quality and duration) in adults with sleep problems?\n2. Does repeated ingestion of kefir impact LDL, triacyglycerols and non-HDLc in adults with sleep problems?\n3. What effect does repeated ingestion of kefir have on cognitive function and mood?\n4.
