California Gold Magnesium Glycinate vs. TRAACS: Label Comparison
These two California Gold Nutrition magnesium products are both sold in vegetarian capsules, but their labels are not interchangeable. This comparison explains their listed elemental magnesium, full serving, ingredient formula and capsule count using product-label research and customer-feedback themes. No hands-on testing was conducted. Checked November 9, 2026.
The Two Labels at a Glance

| Capsules in this bottle | 180 | 240 |
| Suggested use | 3 capsules daily, with food | 2 capsules daily, with food |
| Full servings per bottle | 60 | 120 |
| Elemental magnesium per label serving | 400 mg (95% Daily Value) | 200 mg (48% Daily Value) |
| Per-capsule title amount | 133 mg (rounded) | 100 mg |
| Magnesium source listed | Magnesium glycinate | Magnesium bisglycinate chelate and magnesium oxide |
| Named chelate system stated online | No TRAACS statement found | Albion TRAACS |
| Diet suitability listed | Vegetarian/vegan; formulated without gluten, GMOs or soy | Vegetarian/vegan; non-GMO, gluten-free and soy-free |
What the Ingredient Names Mean
According to the NIH Office of Dietary Supplements, the Supplement Facts panel lists elemental magnesium—not the total weight of the magnesium-containing compound. This is why reading 133 mg per capsule is not the same as comparing the total weight of magnesium glycinate powder.
Magnesium glycinate and bisglycinate are related glycine-bound forms; these two listings do not by themselves prove a different personal result. The TRAACS product’s ingredient list explicitly includes magnesium oxide alongside magnesium bisglycinate chelate. If a fully non-oxide formula matters to you, that detail makes the first listing the one whose current online label better fits your preference. The TRAACS listing is not entirely oxide.
The NIH notes that magnesium absorption varies by form and that, in small studies, citrate, lactate, aspartate and chloride have tended to be more bioavailable than oxide and sulfate. That general information is not proof that either specific bottle is better for a particular shopper. The TRAACS listing’s comparative-absorption claim remains manufacturer copy, not our independent test finding.
Routine and Value Considerations
Why a shopper may choose Magnesium Glycinate 129685
- Higher listed elemental magnesium per full serving: 400 mg
- The online magnesium source says magnesium glycinate without listing magnesium oxide
- The 180-capsule bottle is smaller than the 240-count option
Trade-offs
- Three capsules with food for the label’s daily serving
- 60 full servings per bottle at that amount
- The 400 mg serving is above the NIH supplemental upper limit for adults; it is not an appropriate general target for everyone
Why a shopper may choose Bisglycinate Chelate 103274
- Two capsules daily on the current suggested-use label
- 120 label servings per bottle
- TRAACS is a named supplier and chelate system; the current ingredients still include magnesium oxide
- Some shoppers specifically seek a 200 mg, rather than 400 mg, label serving after professional guidance
Trade-offs
- Half the elemental magnesium per full serving of the other compared bottle
- Not a bisglycinate-only ingredient list
- The longer supply does not by itself establish better total cost or personal tolerance
What I Found in Customer Feedback
The customer insight used here comes only from these iHerb product listings and their self-reported reviews, not Amazon. I summarize themes instead of copying reviews. Buyers of the first product mentioned easier-to-swallow capsules than larger tablets, while others said several capsules per day was inconvenient. Packaging and no unusual smell also received positive mentions. For the TRAACS product, shoppers specifically referred to choosing the branded chelate formulation in a modest capsule routine; some praised the capsule size and routine, while taste and digestive comfort varied by reviewer. These reports are anecdotes—not verified lab tests, verified capsule measurements, or proof of health benefit. Reviews may be changed or removed by the retailer and can reflect packaging or previous formulas.
A Sensible Buying Decision
Choose neither simply because it has more reviews or a high-absorption headline. Check your total intake, health circumstances and medication plan, then compare price per serving, ingredients and capsule count. The two-versus-three-capsule trade-off is clearer than any unverified outcome claim.
The 400 mg serving on the first label exceeds the NIH’s 350 mg adult tolerable upper intake level for supplemental magnesium. This upper limit excludes magnesium naturally present in food and drinks and does not apply to intake supervised by a healthcare professional. High supplemental amounts can cause diarrhea, nausea and cramps, and kidney impairment raises toxicity risk. Magnesium can also interact with some antibiotics and oral bisphosphonates. Read the label and ask a doctor or pharmacist before starting, especially with medication, pregnancy, kidney problems or other medical concerns.
