Growth retardation, also known as failure to thrive, is a condition where a child's growth rate falls significantly below expected patterns for their age and sex. It is caused by nutritional deficiencies, chronic diseases, hormonal imbalances, genetic disorders, or inadequate caloric intake affecting cellular growth and tissue development. The Vitamin B2 (Riboflavin) test is the most important test for diagnosing nutritional causes of growth retardation because it measures essential nutrients required for energy metabolism and cellular growth processes.
Growth retardation is caused by nutritional deficiencies, chronic diseases, hormonal disorders, genetic conditions, or inadequate caloric intake that prevent normal cellular development. Vitamin B2 (riboflavin) deficiency is a common nutritional cause, as this essential vitamin powers energy metabolism and tissue repair processes critical for childhood growth. Other causes include malabsorption disorders, thyroid hormone deficiencies, growth hormone insufficiency, celiac disease, and chronic infections that divert the body's resources away from normal growth processes.
The Vitamin B2 (Riboflavin) test is the most important test for growth retardation because it detects deficiencies in this essential nutrient required for cellular energy production and tissue repair. When riboflavin levels are low, children cannot properly metabolize nutrients for growth, leading to stunted development and poor weight gain. This test is especially critical for infants and young children experiencing unexplained growth delays, as addressing vitamin B2 deficiency can restore normal growth trajectories when caught early.
You should get tested if your child consistently falls below growth curve percentiles, shows poor weight gain over several months, appears significantly smaller than peers of the same age, experiences developmental delays alongside physical growth issues, or has a diet limited in dairy products, eggs, and green vegetables. Testing is especially important if your child shows signs of malnutrition like fatigue, mouth sores, skin problems, or if they have chronic digestive issues that may impair nutrient absorption.
What this means
Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.
Recommended actions
Increase resistance or strength training
Prioritize 7–8 hours of quality sleep per night, try to reduce stress
Include more zinc- and magnesium-rich foods (like shellfish, beef, pumpkin seeds, spinach)
Consider retesting in 3–6 months
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
