Our standards
Nothing hidden.
Nothing borrowed from marketing.
Most supplement labels are written to sell. Ours is written so a pharmacist can read it and know exactly what's in the bottle. Below is the full specification for our Magnesium Glycinate.
Form
Magnesium bis-glycinate
Magnesium bound to two molecules of the amino acid glycine. Among the best-absorbed forms of magnesium in published human studies, and gentle on digestion — unlike oxide, which is poorly absorbed and often causes GI distress.
Elemental dose
275 mg per serving
From 2,500 mg of magnesium glycinate. The label lists both the compound and its elemental yield — the number that actually matters for dosing. No proprietary blends.
Serving size
3 capsules · 30 servings
90 capsules per bottle. One bottle is a 30-day supply at the intended nightly dose.
Other ingredients
Hypromellose capsule. Nothing else.
Plant-based capsule shell. No magnesium stearate, no silicon dioxide, no artificial colors, no fillers, no flow agents.
Testing
Third-party tested, every batch
Independent lab verification for identity, potency, heavy metals (lead, arsenic, cadmium, mercury), and microbial contaminants. Certificate of Analysis available on request.
Manufacturing
United States
Produced in an FDA-registered facility operating under current Good Manufacturing Practices (cGMP, 21 CFR Part 111).
Free from
Gluten, dairy, soy, GMOs
Formulated for adults with common dietary sensitivities. Vegan-friendly capsule.
What's not on the label
Stimulants, melatonin, herbs, proprietary blends
One ingredient. One job. If we can't defend it in a clinical context, it doesn't ship.
Certificate of Analysis
Every batch we produce is sent to an independent laboratory before it ships. The Certificate of Analysis lists the assayed elemental magnesium content and confirms the batch meets our specifications for heavy metals and microbial limits.
To request the CoA for the batch you received, email hello@stilla.co with the lot number printed on the bottom of your bottle.
