Values represent mean ± standard deviation (SD) (% consuming below recommendation, % consuming within recommendation and safe level, % consuming above recommendation/safe level).

* – Mean value is significantly higher (at p < 0.05) than that obtained from the other location; ND – no data.

§ – applies only to supplemental magnesium for healthy adults.

a – National Academies of Sciences, Engineering, and Medicine [36].

b – Institute of Medicine [37].

c – Institute of Medicine [38]; UL – Tolerable Upper Intake Level; PTDI – Provisional Tolerable Daily Intake.

# – Adequate Intake (AI).

## – Recommended Dietary Allowance (RDA).
