4 How does glycine reach the brain’s sleep center?

• Glycine can cross the blood-brain barrier
  

  Glycine can cross the blood-brain barrier and act on the suprachiasmatic nucleus, the brain’s circadian control center that helps start sleep. Learn more.

• Sleep signals move through the digestive tract
• Brain oxygen levels rise sharply after glycine use
• Blood sugar changes carry glycine to sleep nerves

5 Which cells help the epidermis form a water-tight, UV-shielded barrier?

• Melanocytes
• Fibroblasts
• Keratinocytes
  

  Keratinocytes make keratin, which helps block moisture loss, microbial invasion, and ultraviolet (UV) damage in the outer skin layer. Learn more.

• Red blood cells

6 Why do some anti-nausea medicines fail to help with motion sickness?

• They raise stomach acid instead of calming nausea
• Motion sickness is caused only by poor digestion

10 How may melatonin help cells during plastic exposure?

• Plastic particles are broken down into harmless nutrients
• Cell aging speeds up so damaged tissue clears faster
• Mitochondria stay healthier and cellular damage drops
  

  Melatonin helped preserve mitochondrial function and reduce cellular damage, supporting cell energy systems while lowering oxidative stress from plastic exposure. Learn more.

• Inflammation rises to remove plastic from the bloodstream

11 Brown rice from which country was shown to have the highest contamination?

  Immune cells increased right after a single 30-minute sauna session, and some stayed elevated for at least 30 minutes afterward. Learn more.

• Only after several weeks of daily use
• Once body temperature returns to normal
• Several hours after sweating stops

17 What was Crisco originally made from?
