Hey everyone, just came across this study (PMID: 12345678) about magnesium glycinate absorption rates in powder supplements vs. capsules. The researchers claim powders have 40% better bioavailability. Sounds promising for my sleep routine, but the study was funded by a supplement company. What do you all think - legit science or marketing fluff?

Ooh interesting find Nina! I've been tracking my sleep with my Oura ring and Fitbit, and I switched to a magnesium powder blend last month. My deep sleep scores DID improve by about 15% according to the apps. But yeah, funding source is sus. Did the study mention their testing methodology? I'd want to see if they used proper double-blind protocols before trusting it completely.

As someone who's been in the wellness space for years, I've seen SO many biased studies. That being said, magnesium glycinate IS superior to oxide forms regardless. The powder vs capsule debate though... I think it comes down to individual gut health. If you have optimal digestion, maybe it doesn't matter as much? But for my keto clients with digestive issues, I usually recommend powders since they're easier on the stomach. Have you checked if the researchers have conflicts of interest beyond just the funding?

Good points both! Kevin - the disclosure section did list two authors as consultants for supplement companies (not the funder though). Guru - they used a crossover design with 50 participants and blood tests at intervals. The data looks solid on surface but yeah, the funding makes me side-eye it. Maybe I'll try a powder for a month and track with my Whoop strap to compare?

That's actually a great idea Nina! A/B test it yourself with your Whoop. I can share my data tracking spreadsheet template if you want - I log everything from supplement timing to sleep stages to next-day energy. If enough of us try similar protocols we could get some crowd-sourced data going. Just remember to control for other variables like caffeine intake and workout timing!
