Question 1

What is a nutrient deficiency quiz?

Accepted Answer

A nutrient deficiency quiz asks about your diet, lifestyle, medications, and symptoms to estimate which vitamins and minerals you may be lacking. This quiz uses CDC NHANES population data to contextualize your personal risk factors against national deficiency rates.

Question 2

How accurate is this quiz?

Accepted Answer

This quiz identifies risk factors associated with nutrient deficiencies based on published research and CDC data. It cannot replace blood testing. Think of it as a screening tool that helps you decide which nutrients are worth testing for or supplementing.

Question 3

What nutrients are most people deficient in?

Accepted Answer

According to CDC NHANES data, vitamin D is the most common deficiency (22.1% deficient, 58% insufficient), followed by iron (3.5% deficient, 6.2% in women), B12 (3.2%), and magnesium (2.5% deficient, 19% insufficient). Actual rates are likely higher since many people are never tested.

Question 4

Should I get blood work instead of a quiz?

Accepted Answer

Ideally, yes. Blood testing is the gold standard. This quiz helps you identify which tests to ask for and which deficiencies are most likely given your profile. We recommend testing vitamin D (25-OH), ferritin, B12, and magnesium RBC at minimum.

Question 5

How much does it cost to fix nutrient deficiencies?

Accepted Answer

A targeted supplement stack typically costs $0.30-$2.00/day ($9-$60/month) depending on which nutrients you need. This is far cheaper than broad multivitamins and more effective because you are addressing your specific gaps.
