Emerging Noninvasive Biomolecular Checkpoints for Healthy Microbiomes

Advanced Gut &Microbiome Research, Volume 2025, Issue 1, 2025.
Dysbiosis commonly impacts otherwise healthy individuals over the age of 50 due to seemingly innocuous changes in diet, hydration, or physical activity. Noninvasive biomarkers are emerging as checkpoints for immune health, energy‐yielding metabolization, and oxidative stress during the aging process.

A systematic review and meta‐analysis of functional vitamin B12 status among adult vegans

Nutrition Bulletin, Volume 49, Issue 4, Page 463-479, December 2024.
Abstract The dietary intake of vitamin B12 among unsupplemented vegans is notably lower compared to both vegetarians and omnivores. Prolonged low intakes of vitamin B12, such as seen in those adhering to a vegan diet, lead to physiological deficiency of vitamin B12 and an elevated risk of B12‐related morbidity.

Intranasal vitamin B12 administration in elderly patients: A randomized controlled comparison of two dosage regimens

British Journal of Clinical Pharmacology, Volume 90, Issue 8, Page 1975-1983, August 2024.
Aim Vitamin B12 deficiency is common in the elderly population. Standard treatment via intramuscular injections, however, has several disadvantages. Safer and more convenient dosage forms such as intranasal are therefore being explored. This study compares the effects of two intranasal vitamin B12 dosage regimens in elderly vitamin B12‐deficient ...
