Step 2DRIs for creatine

Establish dietary reference intakes

Creatine appears to be a semi-essential nutrient that is naturally present in some foods and available as a dietary supplement. Insufficient data are currently available to establish recommended intakes for creatine. The amount of creatine that individuals need could be influenced by the amount of dietary precursors (glycine and arginine), age, gender, pregnancy and lactation, the capacity to produce creatine endogenously, and genetic disorders that affect creatine needs. The Creatine Global initiative aims to develop the set of nutrient reference values for creatine in healthy population.

Reports describing dietary intake of creatine

Several population-based studies calculated dietary intake of creatine using dietary interviews data.
The Creatine Global Initiative - Children aged 0–24 months
Children aged 0–24 months

The mean dietary intake of creatine in this population was 0.28 ± 0.24 g/day (95% CI, from 0.25 to 0.30). The quartiles of intake were 0.00 to 0.12 g (Q1), 0.13 to 0.20 g (Q2), 0.21 to 0.34 g (Q3), and 0.35 to 1.46 g (Q4).

The Creatine Global Initiative - General population
General population

The average dietary creatine intake across all participants was 1.38 ± 1.13 g (95% CI, 1.35 - 1.41). 57.2% participants were found to have dietary creatine intake below 1 grams per day.

The Creatine Global Initiative - Trends in creatine intake 1999-2018
Trends in creatine intake 1999-2018

The average daily intake of creatine in U.S. children and adults was 13.1 ± 16.5 mg/kg body weight. A significant negative trend for dietary creatine intake was found in infants, and children and adolescents.

The Creatine Global Initiative - Upper level of intake
Upper level of intake

As 5 grams per day was the dose administered to healthy adults with a normal diet, the observed safe level does not require correction, and therefore the observed safe level (tolerable upper intake level) is 5 g/day.
