Every cell in your body depends on oxygen, largely because your mitochondria need it to efficiently produce energy. This clip explains why oxygen deprivation, or hypoxia, is such a powerful form of cellular stress and why studying how cells respond to low oxygen can reveal so much about the body's broader stress response.

Researchers studying a thiamine compound found in garlic discovered something unexpected: modifying the B1 molecule could dramatically change how the body absorbs and uses it. This clip explains how that discovery led to the development of different thiamine derivatives, including forms designed to bypass normal transport limitations and reach tissues more effectively.

Why can increasing vitamin B1 leave some people dizzy, unusually thirsty, or with a racing heart? This clip explores how thiamine deficiency may disrupt the balance of potassium and sodium inside cells, and why restoring B1 can create a sudden shift in potassium demand. That electrolyte change may help explain some of the unexpected symptoms people report when increasing thiamine.
