About this study

In this single-blind, randomized trial, participants will take a daily dose of either 200 or 400 milligrams of magnesium citrate supplement for four weeks, perform three separate handgrip strength tests using a dynamometer, complete a demographics questionnaire, a physical activity questionnaire, and a compliance log.

Treatment and study plan

magnesium

Dietary Supplement

Magnesium citrate of either 200mg or 400 mg will be taken by the participant with food in the morning.

Primary outcomes

  1. Hand grip strength

    Time frame: change between baseline and 4 weeks

    Participants will perform three separate handgrip strength tests using a Jamar Plus digital hand dynamometer, (Sammons Preston, Bolingbrook, Illinois).

    In each test, participants will do three trials resting for 15 seconds between trials, the average of the three trials will be recorded. To perform the hand grip strength test, the participant will hold the dynamometer in their dominant hand, with the arm at a right angle, and with the elbow by the side of the body. The participant then squeezes the hand dynamometer with maximum isometric effort for at least five seconds. Participants are required to not move any other part of the body and are encouraged to use maximum effort.
