ProCare Health Magnesium Glycinate 400 mg
400mg of magnesium glycinate per serving, stated as 95% of the daily value, in 90 vegan capsules at $16.99. It is here partly on its own merits and partly as a yardstick: several GLP-1 companion products in this directory list magnesium at amounts that are a rounding error against this figure.

What’s in it
Amounts are shown only where the manufacturer publishes them. Anything without a figure is undisclosed — and for an active ingredient, an undisclosed dose is the central problem with this category.

One of the better-tolerated and better-absorbed magnesium forms
- Glycineamount not published
Inherent to the glycinate form; has its own research on sleep quality
How the manufacturer says it works
ProCare Health states the product delivers 400mg per serving at 95% of the daily value in a well-tolerated, bioavailable form, supporting muscle function, cardiovascular function and blood pressure already within a normal range, the body's natural relaxation response and a normal physiological stress response. It notes the glycinate form also delivers glycine, an amino acid with its own research on sleep quality.
What the evidence actually supports
This is a properly dosed single-nutrient product and there is little to argue with. 400mg is the actual daily requirement range for adults, the percent daily value is published alongside it, and glycinate is a genuinely well-tolerated form — magnesium oxide, the cheap alternative, is poorly absorbed and notorious for causing loose stools. The glycine point is accurate rather than decorative: glycinate does deliver glycine, and glycine has its own sleep research. Claims are framed as structure-function support rather than treatment. $16.99 for 90 capsules is inexpensive.
Where that evidence stops
Magnesium does not cause weight loss and ProCare does not claim it does. Its relevance to this directory is narrower and real: appetite suppression on a GLP-1 reduces intake of everything, magnesium included, and low magnesium contributes to fatigue, cramps and poor sleep. Magnesium can also interact with some medications — certain antibiotics and thyroid medication need to be timed away from it — and people with kidney impairment should not supplement magnesium without medical advice. No third-party testing statement is published.
Strengths and problems
Strengths
- 400mg is a genuine full daily dose, published with its percent daily value (95%)
- Glycinate is one of the better-tolerated and better-absorbed forms, unlike cheap magnesium oxide
- The glycine point is accurate — the form does deliver it, and glycine has its own sleep research
- Claims are framed as structure-function support, not treatment
- $16.99 for 90 capsules is inexpensive for a properly dosed single nutrient
- Useful yardstick: several GLP-1 companion products list magnesium at a fraction of this
Problems
- Magnesium does not cause weight loss and is not a GLP-1 mechanism
- Can interact with some antibiotics and thyroid medication, which need timing apart from it
- Not suitable without medical advice if you have kidney impairment
- No third-party testing statement
- Directions and warnings are not published in the description we captured
- Free shipping threshold of $100 is high for a $16.99 product

May suit
Someone on a GLP-1 whose intake has dropped and who wants a properly dosed magnesium rather than a token amount inside a blend.
Do not use if
- You have kidney disease or impaired kidney function — do not supplement magnesium without medical advice
- You take thyroid medication or certain antibiotics without timing them apart from magnesium
- You are already taking magnesium in another supplement and would be stacking
Frequently asked
How does this compare with the magnesium in GLP-1 electrolyte products?
It is a different order of magnitude. This is 400mg, 95% of the daily value. Several electrolyte and companion products in this directory list magnesium at 15mg or similar — under 4% of a day's requirement. Both can be reasonable products; just do not count the smaller one as your magnesium source.
Why glycinate rather than a cheaper form?
Magnesium oxide is cheap, poorly absorbed and commonly causes loose stools. Glycinate is better tolerated and better absorbed, and it carries glycine, which has its own research on sleep. The form genuinely matters here.
