Approved regimen (Tymlos): 80 µg once daily by subcutaneous injection (abdomen), via a metered prefilled pen. This is a prescription drug — dose, duration and monitoring are set by a prescriber. The current US label still says that use for more than 2 years during a patient's lifetime is not recommended. There is no validated use outside osteoporosis fracture prevention.
Any time of day
Tymlos prefilled injector pen (prescription, via a clinician)
200-250mg elemental magnesium daily
Evening for sleep/relaxation (glycinate), Morning for energy (malate), Anytime (citrate)
