Magnesium L-Threonate with Magtein: 90 vs 180 Capsules
Share
Magnesium supplements come in many forms, and the amount of magnesium on the front of a bottle does not tell the whole story. Sports Research Magnesium L-Threonate with Magtein is available at BPBalance in 90- and 180-capsule bottles. Here is how to compare them.
What is magnesium L-threonate?
Magnesium L-threonate is a specific magnesium compound. Magtein® is a branded form used in this Sports Research product. It is different from magnesium glycinate, citrate and oxide, so compare products by form, serving size and label directions—not only by capsule count.
90 capsules vs 180 capsules
| Detail | 90 capsules | 180 capsules |
|---|---|---|
| Serving size | 3 capsules | 3 capsules |
| Servings per bottle | 30 | 60 |
| Elemental magnesium per serving | 144 mg | 144 mg |
| Magnesium L-threonate per serving | 2,000 mg | 2,000 mg |
| What changes | Smaller bottle count | Twice as many capsules |
| How to compare value | Current bottle price ÷ 30 servings | Current bottle price ÷ 60 servings |
The formula is the same across both sizes. The difference is the number of capsules in the bottle. The 90-capsule option is a smaller initial purchase. The 180-capsule option provides twice as many capsules and may reduce how often regular users need to reorder.
How many capsules are taken?
The current product imagery directs adults to take three capsules daily. At that serving pattern, a 90-capsule bottle supplies approximately 30 servings and a 180-capsule bottle supplies approximately 60 servings. Confirm the directions on the bottle you receive because labels can change.
Is Magtein the same as magnesium glycinate?
No. Magnesium L-threonate and magnesium glycinate are different forms. A shopper choosing between them should consider the labeled serving, capsule count, personal tolerance and advice from a qualified healthcare professional.
What should you compare before buying?
- The magnesium form listed on the Supplement Facts panel
- Capsules required per serving
- Total servings per bottle
- Other ingredients and dietary preferences
- Price per serving rather than price per bottle alone
Which bottle size is more practical?
Choose 90 capsules if you prefer the smaller bottle or want to try the format first. Choose 180 capsules if you already use the product consistently and want a longer supply. Selecting the larger count is not a reason to exceed the suggested serving.
