Three Things To Know Before You Buy

  • 1It is bisglycinate, and only bisglycinate.Bisglycinate means the magnesium is bound to the amino acid glycine. That is what the second word on the front of the bottle means. There is no other form of magnesium in here and no blend.
  • 2400 mg a serving, which the panel puts at 95% of the Daily Value.A serving is 2 capsules, so that is 200 mg a capsule. Both numbers are on the Supplement Facts panel further down this page.
  • 3A bottle is 45 servings.Ninety capsules, two capsules a serving. That is Servings Per Container, printed on the panel further down this page.

Nothing on this page is a round number someone liked the look of. Every figure is off the label or the panel.

Straight Off The Back Of The Bottle

Not a rewrite. This is what the label says, word for word.

  • 1Suggested use“(ADULTS ONLY) As a dietary supplement take 2 capsules per day with food or as recommended by a health care practitioner.”
  • 2The claim“Supports energy production.”
  • 3Caution“Pregnant women, lactating women, and anyone taking medications, should consult a health care professional before using any nutritional product.”
The back label of Martin Clinic Magnesium Bisglycinate showing the suggested use and caution text

The back of the bottle, unretouched.

If a line is not on the bottle or on the panel, it is not on this page.

The Other Ingredients Line Is Two Words Long

Because there are only two.

Turn the bottle over and the Other Ingredients line reads, in full, “Hypromellose Capsule, Water.”

Hypromellose is the capsule shell. It is plant based, which is why the panel says this is suitable for vegans and vegetarians. The water is what the capsule is made with.

That is the whole list. There is no filler, no flow agent and no coating hiding behind a longer word.

No artificial preservatives, colors or sweeteners. No dairy.

Non-GMO. Gluten free.Suitable for vegans and vegetarians.

Every one of those lines is printed on the label or the panel.

Dr. Martin on this

What form of magnesium is this?

Bisglycinate, and only bisglycinate.

Bisglycinate means the magnesium is bound to the amino acid glycine. It is the only active ingredient in the bottle. There is no second form and no blend.

★★★★★“So effective for aiding in falling asleep, and it is an easier form of magnesium for those people like me who are prone to digestive problems.”Deborah T.

Dr. Martin on this

What else is in the capsule?

A capsule shell and water. The Other Ingredients line reads, in full, “Hypromellose Capsule, Water.”

The panel also says it contains no artificial preservatives, colors, sweeteners or dairy, and that it is suitable for vegans and vegetarians. The label adds non-GMO and gluten free.

Can I take it if I am pregnant, nursing, or on medication?

Ask your own health care professional first. That is the label’s instruction, not ours.

The caution on the bottle reads “Pregnant women, lactating women, and anyone taking medications, should consult a health care professional before using any nutritional product. If any adverse reactions occur, discontinue use and consult a health care professional.”

It is also an adults-only formula, and it should be kept out of reach of children.

Dr. Martin on this

What if it isn’t for me?

Send it back. Sixty days, money back, no questions asked, even if the bottle is empty.

That guarantee is on every Martin Clinic order, not just this one.
