Does magnesium glycinate interact with atorvastatin?

No interaction, and why, with the timing settled

Does magnesium glycinate interact with atorvastatin: no, and the reason sorts every statin at once. The interactions that magnesium has with medicines are chelation, binding a drug in the gut so it is not absorbed, which belongs to the tetracyclines, the fluoroquinolones, the bisphosphonates, levothyroxine and gabapentin, and status effects, where a medicine changes magnesium's picture, which belongs to the proton-pump inhibitors, the diuretics and digoxin. Atorvastatin belongs to neither: statins are not chelated by minerals, are absorbed and cleared by pathways magnesium does not touch, atorvastatin through the liver's CYP3A4 system where the real statin interactions live, grapefruit, certain antibiotics and antifungals, and have no documented interaction with any magnesium salt, so a reader on atorvastatin, simvastatin, rosuvastatin or pravastatin takes magnesium glycinate freely, at the same meal or a different one. The timing settles itself: atorvastatin is often taken in the evening by convention, though its long action makes the hour flexible, and magnesium is taken with the evening meal for adherence and tolerance, so the two may share the evening or not, with no spacing rule between them. The standing rule applies as always, that anyone on regular medication runs the whole cupboard past a pharmacist once, and the pharmacist will confirm the statin needs no spacing from magnesium.

The question the question usually hides, statin muscle symptoms, and what to do about them instead of a mineral

The question usually hides a different one, because a lifter on a statin who searches magnesium and atorvastatin together is often a lifter with aching muscles who has heard that magnesium helps muscles. Statin-associated muscle symptoms, aches, weakness, stiffness and cramps, are real, are the commonest reason people stop statins, and are worth a page of their own: they are usually symmetrical, in large muscle groups, thighs, calves, shoulders, arrive within weeks to months of starting or increasing a statin, and are more common with higher doses, with some statins more than others, in older people and with certain interacting medicines, and a small minority progress to a measurable rise in the muscle enzyme creatine kinase that a blood test finds. Magnesium has never been shown to prevent or treat them: no trial of magnesium for statin myalgia exists, the coenzyme Q10 trials that the folklore also cites are mixed and unconvincing, and magnesium's claim is normal muscle function in a replete person, not a treatment for a drug effect, so a lifter who takes magnesium for statin aches has taken a safe mineral for a reason it cannot serve. What to do instead is the prescriber's conversation: a statin muscle ache is reported to the GP, who may check creatine kinase, pause the statin to confirm the link, lower the dose, switch to a different statin or a different dosing pattern, alternate-day dosing being one option, or move to a non-statin cholesterol treatment, the guidelines on statin intolerance giving a sequence that keeps the cardiovascular benefit while removing the ache, and a lifter should never stop a statin on their own account or replace it with a supplement. The question filed: magnesium glycinate does not interact with atorvastatin, the two being taken together or apart at any hour, and the muscle ache that usually prompts the search is a statin conversation for the prescriber rather than a magnesium question, the worked example being fine beside a statin and taken for its own sentences, 300mg elemental at 22p, £19.99 for 90 days.

The verdict, no interaction and a different conversation

Does magnesium glycinate interact with atorvastatin: no, statins being neither chelated by minerals nor cleared by a pathway magnesium touches, so the two are taken together or apart at any hour with no spacing, and the muscle ache that usually prompts the search is statin-associated muscle symptoms, the commonest reason people stop statins, which magnesium has never been shown to prevent or treat and which the prescriber manages by a creatine kinase check, a pause, a lower dose, a different statin or a non-statin treatment, never by a supplement and never by stopping alone. Fine beside a statin: Futuro Labs Magnesium Glycinate, bisglycinate, 300mg elemental at 80% NRV, £19.99 for 90 days at 22p a day, for its own sentences.

Questions people also ask

Can I take magnesium with atorvastatin?

Yes: statins are not chelated by minerals and are cleared by liver pathways magnesium does not touch, so magnesium glycinate is taken at the same meal or a different one with no spacing, a pharmacist confirming in a sentence.

Does magnesium help with statin muscle pain?

No: statin-associated muscle symptoms have never been treated or prevented by magnesium in any trial, magnesium's claim being normal muscle function in a replete person, and the aches are managed by the prescriber through a creatine kinase check, a pause, a dose or drug change or a non-statin treatment.

What are statin muscle symptoms like?

Usually symmetrical aches, weakness, stiffness or cramps in large muscle groups, thighs, calves and shoulders, arriving within weeks to months of starting or increasing a statin, commoner at higher doses and in older people, with a minority showing a raised creatine kinase on a blood test.

Should I stop my statin if my muscles ache?

Not on your own: report the ache to the GP, who may check creatine kinase, pause the statin to confirm the link and then lower the dose, switch statin, try alternate-day dosing or move to a non-statin treatment, keeping the cardiovascular benefit while removing the ache.

Which medicines actually interact with atorvastatin?

Grapefruit and certain antibiotics and antifungals that act on the liver's CYP3A4 system, and some other drugs the prescriber screens for, none of which is a mineral supplement.
