Supplement Comparison
They're the same compound. 'Bisglycinate' is the chemically precise name (one magnesium bound to two, or 'bis', glycine molecules), and 'glycinate' is the everyday shorthand for exactly the same thing. Any real-world difference comes from the brand, not the word: whether it's fully chelated or cheaply 'buffered' with magnesium oxide, plus fillers and the elemental dose. Any source that recommends 'glycinate' is recommending bisglycinate.

Chemistry
Magnesium Bisglycinate
Magnesium + two glycine molecules ('bis' = two)
Magnesium Glycinate
Identical — 'glycinate' is shorthand for the same bis-glycine chelate
The Name
Magnesium Bisglycinate
The precise, technical label brands use to sound premium
Magnesium Glycinate
The common everyday label — same product
The Real Variable
Magnesium Bisglycinate
Fully chelated vs 'buffered bisglycinate' (cut with cheap magnesium oxide to lower cost)
Magnesium Glycinate
Same — always check for 'buffered' and read the elemental dose
Absorption
Magnesium Bisglycinate
Well-absorbed, gentle (glycine chelate)
Magnesium Glycinate
Identical
Elemental Magnesium
Magnesium Bisglycinate
Varies by product, not by the name
Magnesium Glycinate
Varies by product, not by the name
What the sources say
Magnesium Bisglycinate
When a source says 'glycinate', it means this compound
Magnesium Glycinate
Named for daily use and sleep
Save yourself the confusion: magnesium bisglycinate and magnesium glycinate are the same molecule. 'Bis-glycinate' just spells out that two glycine molecules are bound to each magnesium, which is what 'glycinate' has always meant. Marketers use 'bisglycinate' because it sounds more scientific, but the compound is the same. What varies between products is quality: some cheap 'buffered bisglycinate' powders are partly magnesium oxide, which dilutes the well-absorbed chelate you're paying for. So ignore the label word, avoid 'buffered' versions if you want the gentle fully-chelated form, and check the elemental magnesium per serving. Under either name, this is the form named for daily use and sleep.
