Bluebonnet Albion Chelated Magnesium vs. Electric Tiger: Label Check
Bluebonnet names its compound magnesium bisglycinate chelate and states its magnesium stearate is vegetable-sourced, but doesn't print the compound weight, so the ratio check that works on our label can't run on theirs.
We make Electric Tiger Magnesium Glycinate, which competes with the product compared here. Every figure about Bluebonnet Albion Chelated Magnesium is read from its own site, checked on 26 September 2026, and linked below. If something has changed, tell us and we will update it. Bluebonnet is a trademark of its owner; Electric Tiger is not affiliated with Bluebonnet.
The short answer: Bluebonnet's label lists 200 mg of magnesium per serving (48% DV) as magnesium bisglycinate chelate (Albion®) — the same chelate most labels call magnesium glycinate — but it doesn't print the compound weight, so the magnesium-to-glycinate ratio can't be checked from this label. Ours lists 275 mg of magnesium from 2,500 mg of magnesium glycinate, an 11% ratio, under the 14% chemical ceiling. Bluebonnet's 60-capsule bottle is $16.95 on its site ($15.26 on the first subscription order); ours is as low as $16.31 a bottle on subscription.
The two labels, side by side
| Bluebonnet Albion Chelated Magnesium | Electric Tiger Magnesium Glycinate | |
|---|---|---|
| Serving size | 2 vegetable capsules | 3 capsules |
| Servings per bottle | 30 | 30 |
| Magnesium per serving | 200 mg | 275 mg |
| % Daily Value | 48% | 65% |
| Compound named on label | Magnesium bisglycinate chelate (Albion®) | Magnesium Glycinate |
| Compound weight per serving | Not stated on the label | 2,500 mg |
| Magnesium ÷ compound weight | Can't be checked — compound weight not printed | 11% |
| Other ingredients | Capsule (hypromellose, purified water), vegetable magnesium stearate | Hypromellose (capsule), magnesium stearate, silicon dioxide, rice flour |
| Certifications printed | Non-GMO certified by NSF | None held |
| Price (60-capsule bottle) | $16.95 on its site ($15.26 on the first subscription order, then 10% off) | As low as $16.31 a bottle on subscription |
| Price per 100 mg magnesium | about $0.25 (subscription) | about $0.20 |
Why the ratio can't be checked on this label
Magnesium bisglycinate chelate — the compound name Bluebonnet prints, supplied under the brand name Albion — is chemically the same chelate as the magnesium glycinate named on our label: one magnesium atom bound to two molecules of the amino acid glycine, formula C4H8MgN2O4, molecular weight 172.42, of which the magnesium atom weighs 24.3. So magnesium is at most about 14.1% of that compound by weight. Bluebonnet's label states the magnesium (200 mg) but not the compound weight it came from, so that division isn't possible from what's printed. Ours states both: 275 mg of magnesium from 2,500 mg of magnesium glycinate, an 11% ratio, under the ceiling.
Where each label does better
Bluebonnet carries Non-GMO certification from NSF, which we do not hold on this product, and specifies that its magnesium stearate is vegetable-sourced; ours lists magnesium stearate without stating a source. It also sells a larger 120-capsule bottle on its site, at $29.50, for buyers who want more servings in one purchase.
How to check any magnesium label
- Find the row that names magnesium on its own. That amount is the magnesium.
- Find the compound in brackets and its weight, if the label gives one.
- Divide the first by the second. For magnesium glycinate or bisglycinate, expect about 14% or a little less. If the label doesn't print the compound weight, this step stops here.
- Compare prices on magnesium, not bottles: our magnesium page has a calculator for price per 100 mg.
