Question 1

What does the term 'bioavailability' mean in the context of dietary supplements?

Accepted Answer

The proportion of a nutrient or compound that is absorbed and available for use by the body

Answer

Bioavailability refers to the fraction of an ingested substance that reaches systemic circulation and is available to exert its physiological effect.

Question 2

A client following a strict plant-based diet is concerned about nutrient deficiencies. Which vitamin is MOST commonly deficient in vegans due to its near-exclusive presence in animal products?

Accepted Answer

Vitamin B12 (cobalamin)

Answer

Vitamin B12 is found almost exclusively in animal-derived foods; vegans are at significant risk for deficiency and should supplement or consume B12-fortified foods.

Question 3

Which mineral is involved in over 300 enzymatic reactions in the body, commonly deficient in the US population, and often recommended by holistic coaches for stress, muscle tension, and sleep?

Accepted Answer

Magnesium

Answer

Magnesium participates in over 300 enzymatic processes including ATP production, muscle relaxation, and nervous system regulation, and is widely deficient due to processed food diets.

Question 4

Which form of magnesium supplement is generally considered best tolerated and most bioavailable for systemic effects such as sleep and stress reduction?

Accepted Answer

Magnesium glycinate

Answer

Magnesium glycinate (bound to the amino acid glycine) is highly bioavailable, gentler on the GI tract, and glycine itself has calming properties that complement magnesium's relaxing effects.

Question 5

A client asks about omega-3 fatty acid supplements for inflammation. Which source provides EPA and DHA in their preformed, readily usable state?

Accepted Answer

Fish oil or algae oil

Answer

EPA and DHA are the biologically active omega-3s; fish oil and algae oil contain these in preformed state, whereas flaxseed provides ALA which must be converted (inefficiently) to EPA/DHA.
