  Geranylgeraniol (GG) occurs naturally in foods like olive oil and annatto, with annatto seeds being a particularly rich source for supplements. Learn more.

4 How does butyrate help improve insulin sensitivity?

• It speeds up sugar absorption
• It raises stress hormone output
• It boosts GLP-1 release
  

  Butyrate supports glucagon-like peptide-1 (GLP-1) release, which helps slow gastric emptying, reduce appetite, and improve blood sugar control. Learn more.

• It blocks digestion in the stomach

5 What is the best natural source of vitamin D?

• Fatty fish
• Egg yolks
• Sunlight
  

  Sunlight helps your skin make vitamin D. Exposing more skin surface can speed up production while reducing the time you’re exposed to ultraviolet (UV) rays. Learn more.

• Fortified milk

6 What is the process called when a dead hang helps tendons respond to stretch and grow stronger?

• Glycolysis
• Mechanotransduction
  

  Mechanotransduction is how the body senses tension and turns it into stronger, thicker connective tissue, such as tendons and ligaments. Learn more.

• Oxidation
• Vasodilation

7 Which part of the body’s defense system was disrupted by eating a high-fat diet?

• Enzymes that control glutathione
  

  Eating a high-fat diet altered enzymes tied to glutathione, one of the body’s main antioxidants, reducing the cells’ ability to handle stress and damage. Learn more.

• Hormones that regulate thirst
• Proteins that build collagen
• Cells that produce melatonin

8 How many people in the U.S. have a thyroid disorder?

• 5 million
• 10 million
• 15 million
• 20 million
  

  More than 20 million Americans have a thyroid disorder, and about 60% do not know they have one. Learn more.

9 What is the main fat found in olive oil?

• Oleic acid
  

  Oleic acid, the main fat in olive oil, can switch on signals that promote new fat cell formation over time. Learn more.

• Linoleic acid
• Palmitic acid
• Stearic acid

10 What are the most common ways hydrogen therapy is used?

• Skin patches, capsules, and nasal drops
• Powders, injections, and eye sprays
• Inhaled gas, hydrogen-rich water, and infused saline
  

  Hydrogen therapy is given by inhaling hydrogen gas, drinking hydrogen-rich water, receiving hydrogen-infused saline, or using tablets that release hydrogen in water. Learn more.

• Massage oils, creams, and lozenges

11 Which exercise can show strength differences between your left and right leg?

• Deadlifts
• Lunges
  

  Lunges train one leg at a time, which helps expose side-to-side strength differences while also building balance, stability, and lower-body strength. Learn more.

• Pushups
• Planks

12 How much did the National Institutes of Health (NIH) spend on Alzheimer’s research?

• $1.9 billion
• $2.9 billion
• $3.4 billion
• $3.9 billion
  

  National Institutes of Health (NIH) spending on Alzheimer’s research reached $3.9 billion in 2024, up from $2.9 billion in 2020. Learn more.

13 Which coating is often added to liposomes to help them stay in the bloodstream longer?

• Polyethylene glycol (PEG)
  

  Polyethylene glycol (PEG) can extend circulation time, but some people carry anti-PEG antibodies that can trigger reactions, and the coating does not break down easily. Learn more.

• Citric acid
• Collagen protein
• Sodium chloride

14 Which of these natural remedies isn’t appropriate for nasal polyps?

• Steam therapy
• Saline rinses
• Raw honey
• Apples
  

  Steam therapy, saline rinses, and certain natural substances like raw honey are commonly used to help relieve nasal congestion and irritation. Apples are not used as a remedy for nasal polyps. Learn more.

15 Which statement about niacinamide is true?

• Its vitamin K content makes you sweat out toxins
• It has the same main compounds as nicotine
• It supports skin repair via nicotinamide adenine dinucleotide (NAD+)
  

  Niacinamide helps replenish nicotinamide adenine dinucleotide (NAD+), which skin cells need for energy, DNA repair, and inflammation control. Learn more.

• It helps you grow full, lush, hair because of its niacin content

16 What’s the main downside of repeating the same exercise pattern over time?

• Higher appetite after workouts
• Lower heart rate during rest
• Faster gains in muscle size
• More stress on the same joints and tissues
  

  Repeating one movement pattern over time concentrates strain on the same areas, which raises injury risk. Learn more.

17 What’s the best time of year to amend soil?

• Fall
  

  Fall is best because the growing season has just ended, the soil is still workable. The cooler weather and moisture also support nutrient retention and microbial activity. Learn more.

• Winter
• Early summer
• Mid-spring

18 How does Ultraviolet Blood Irradiation (UVBI) help improve circulation?

• By shifting stomach acid and slowing normal digestion
• By raising blood sugar and changing meal response
• By limiting oxygen flow through body tissues
• By improving zeta potential and supporting vasodilation
  

  Ultraviolet Blood Irradiation (UVBI) may improve circulation by restoring zeta potential and increasing nitric oxide, which helps blood vessels relax and widen. Learn more.

19 Which hormone was shown to halt tumor growth in prostate cancer models?

• Cortisol
• Insulin
• Dihydrotestosterone (DHT)
  

  In prostate cancer models, dihydrotestosterone (DHT) stopped tumor growth and, when paired with an aromatase inhibitor, led to tumor disappearance in most animals. Learn more.

• Estrogen

20 Which of these is not described as a type of Alzheimer’s disease?

• Autoimmune
  

  Alzheimer’s has multiple different subtypes, depending on its cause — the treatment also varies depending on the subtype. Learn more.

• Inflammatory
• Atrophic
• Toxic

21 How much less adenosine triphosphate (ATP) do people produce today compared to a century ago?

• 25% less
• 50% less
• 60% less
• 75% less
  

  ATP production is estimated to have declined by up to 75% compared to a century ago, largely due to mitochondrial dysfunction caused by modern toxins, which is linked to many diseases. Learn more.
