Weekly Health Quiz: Iron Overload, Niacinamide Supplements, and Benefits of Hydrogen-Rich Water

1 What happens when reductive stress drains NADPH in your body?

• Your blood sugar drops sharply
• Your natural antioxidant defenses are disrupted

  NADPH supports enzymes that protect cells from oxidative damage; when it’s drained, your antioxidant defenses falter, leaving cells more vulnerable. Learn more.

• Your mitochondria produce more heat than energy

• It caused multiple aggressive cancers in rats

  Long-term glyphosate exposure caused cancers such as leukemia, thyroid tumors, and nerve sheath cancers in rats. Learn more.

3 If your mitochondria are overloaded with excess NADH and FADH2, what is most likely to happen?

• Slower calorie burning
• More ATP production than your body can use
• Energy production jams and cell damage begins

  Too much NADH and FADH2 clogs the electron transport chain, slowing energy flow and triggering damaging byproducts inside cells. Learn more.

6 What happens if you eat more than 45% of your daily calories after 5 p.m., even without changing your total calories or weight?

• Your metabolism accelerates while you sleep
• Your calorie burn remains unchanged
• Your glucose tolerance worsens significantly

  Consuming most of your calories late in the day disrupts glucose tolerance, increasing your risk of blood sugar spikes and insulin resistance. Learn more.

• Your risk for indigestion increases

7 What happens to the cellular cleanup process, autophagy, when your liver cells are exposed to microplastics?

• It is activated but fails to complete, causing buildup

  Autophagy is triggered by microplastics but fails to complete, leading to a buildup of damaged material in liver cells. Learn more.

• It completes effectively, removing all damaged material
• It shuts down completely, preventing any cleanup
• It speeds up, clearing all microplastics

8 Why might it be hard to know if a product contains titanium dioxide in the U.S.?

• It’s banned in certain products only
• It often appears without clear labeling

  Titanium dioxide is still legal in the U.S. and is often included in products without transparent labeling. Learn more.

• It is only used in industrial cleaning products
• It’s only sold in liquid form

9 What is one simple daily habit that can help improve your sleep quality?

• Avoiding large meals right before bed
• Minimizing naps throughout the day
• Eating snacks right before bed
• Getting morning sunlight

  Exposure to natural light in the morning helps align your circadian rhythm, making it easier to fall asleep and stay asleep at night. Learn more.

10 What is one of the main roles of niacinamide in your body?

• Increasing cholesterol production
• Increasing protection from free radical-induced damage
• Recycling and restoring NAD⁺ for energy and repair

  Niacinamide is a form of vitamin B3 that helps restore NAD⁺, which is critical for energy production, cellular repair, and metabolic stability. Learn more.

• Supplementing your body’s protein synthesis

11 How common is silent fatty liver disease among people with Type 2 diabetes?

• About 10%
• About 25%
• Nearly 60%

  Research shows that nearly 60% of people with Type 2 diabetes have fatty liver disease, often without symptoms. Learn more.

• Over 80%

12 Which gastrointestinal cancer is rising fastest among younger adults?

• Appendix cancer

  Appendix cancer is now one of the fastest-growing gastrointestinal cancers, with a third of cases in people under 50. Learn more.

• Colon cancer
• Stomach cancer
• Pancreatic cancer

13 What role did RFK Jr. play in changing Monsanto's legal landscape?

• He negotiated a settlement that benefited both Monsanto and cancer victims
• He successfully sued Monsanto for cancers caused by Roundup (glyphosate)

  RFK Jr.'s successful lawsuits against Monsanto for cancers caused by Roundup (glyphosate) marked a turning point that ended over a century of the company producing toxic products with minimal consequences. Learn more.

• He worked as Monsanto's legal advisor to minimize their liability
• He conducted independent research proving Roundup's safety

14 What is the suggested pace during the slow-walking segments of Interval Walking Training (IWT)?

• Conversational pace

  Slow periods should be at a comfortable pace where you can carry on a conversation, helping with recovery and endurance. Learn more.

• Maximum effort pace
• Barely moving pace
• Jogging pace

15 How do tremors linked to nutrient deficiencies typically behave?

• They worsen when your hands are at rest
• They occur only during sleep
• They worsen with movement, not rest

  Tremors from deficiencies often intensify during movement, unlike Parkinson’s tremors which occur mainly at rest. Learn more.

• They stop after caffeine intake

16 How does molecular hydrogen in hydrogen-rich water support your body during exercise?

• It acts as a selective antioxidant and protects mitochondria

  Molecular hydrogen acts as a selective antioxidant, activates your body’s antioxidant defenses, and protects mitochondria to support exercise recovery. Learn more.

• It reduces oxidative stress levels to encourage muscle growth
• It supports your body’s natural antioxidant defenses
• It solely enhances hydration while leaving cells unaffected

17 What is the main driver of adenomyosis?

• Genetic mutations only
• Low progesterone from birth
• Bacterial overgrowth in the uterus
• Estrogen overload

  Excess estrogen is the primary factor behind adenomyosis, and it can be aggravated by birth control, plastics, and hormone disruptors. Learn more.

18 What happens when curcumin is well absorbed in the body?

• It binds to a protein that suppresses inflammatory genes
• It dissolves exclusively in stomach acid with no subsequent impact
