Post Meridiem — Magnesium Glycinate

Magnesium, for the night.

Supports muscle relaxation and healthy, restful sleep.* Magnesium glycinate is a gentle, well-absorbed form. Made without melatonin — non-habit-forming.

How to take it

Three capsules about an hour before bed. Magnesium glycinate supports muscle relaxation, which is the wrong thing to do at 9 a.m. — so it belongs at the end of the day, not the start.

Every ingredient, every amount

Per 3-capsule serving. 30 servings per bottle.

Other ingredients: hypromellose (capsule), magnesium stearate, silicon dioxide, rice flour. Nothing else.

One active. One amount. The same number is printed on the front of the bottle and on the Supplement Facts panel in the images above.

How this is tested

Our manufacturer holds documentation for this product. Here is what exists, stated exactly.

• Third-party tested — analysed by an outside laboratory, not only in-house.
• Batch certificate of analysis on file (ref. MGL250923).
• cGMP certified manufacturing facility, certified by NSF.
• ISO/IEC 17025 accredited testing laboratory.
• FDA registered facility.

What “FDA registered” does not mean. It means the facility is listed with the FDA, which is required of anyone manufacturing supplements in the United States. It does not mean the FDA has approved, evaluated or endorsed this product. No dietary supplement is FDA approved, and any brand implying otherwise is misleading you.

Email hello@meridiemlabs.com with your order number and we will send you the certificate of analysis for the batch you received.

Before you double up

Check the total magnesium across everything you take. Magnesium is the one most people accidentally double up on. This formula provides 275 mg elemental magnesium per serving (65% of the Daily Value).

Why this costs more than the cheapest option

You can find magnesium glycinate at this exact strength for around $20. We know, because we looked before setting our price. Here is what the difference buys, stated plainly so you can decide whether it is worth it.

• Shipping is included. A $20 bottle plus shipping is not a $20 bottle. Ours is $39 delivered, every time, with no minimum order.
• A 60-day guarantee on an opened bottle. Most marketplace sellers will not take back a supplement you have started taking. We refund it and you keep the bottle.
• Documentation you can ask for. Third-party testing, an NSF-certified cGMP facility, and a batch certificate of analysis we will email you on request. Many cheap listings cannot tell you who made the product.
• One company, one inbox. If something is wrong you email us and a person answers. There is no third-party seller in between.

What it does not buy is a different molecule. Magnesium glycinate is a commodity ingredient. At the same dose, what is in our bottle is what is in a cheaper one, and we are not going to invent a reason why ours is chemically superior. If price is your deciding factor, buy the cheaper bottle — you will get magnesium. Buy this one if you want the dose printed on the front, documentation on request, a guarantee that survives opening the seal, and someone to answer the email.

What we won't do

• No melatonin. This works with your own rhythm, not a hormone that overrides it.
• No proprietary blends. Every active and its amount is printed on the front.
• No claims that this treats or prevents any condition.

Questions we get

Will this make me drowsy?
Magnesium supports muscle relaxation rather than sedation. It is not a sleeping pill and does not contain melatonin. Most people take it about an hour before bed.

Why three capsules instead of one?
Because 275 mg of elemental magnesium requires 2,500 mg of magnesium glycinate, and that does not fit in one capsule. A single-capsule product at this claim is either a smaller dose or a different, harsher form.

Glycinate or bisglycinate?
The same chelate. Labels use both names.

Can I take it with other supplements?
Yes, but add up your total magnesium first — it is in many multivitamins and powders. If you have a kidney condition or take medication, speak to your doctor.

How do I cancel a subscription?
One click from your account page, or one email. No fee, no minimum. We send a reminder before every renewal.

What if it does not work for me?
Email us within 60 days and we refund the order. You keep the bottle.

No reviews yet

We launched recently, so there are no reviews on this page. We could buy some — plenty of brands do — but a testimonial you cannot verify is worth less than a number you can check yourself.

So instead: one active, one amount, a full ingredient list, third-party testing you can request the certificate for, and an honest account of why a cheaper bottle exists. Compare all of it against anything else on the shelf.

When real reviews arrive, they appear here unedited, including the bad ones.
