Pros and cons
High Absorption Magnesium (Lysinate Glycinate)
- Fully chelated magnesium lysinate glycinate made with Albion TRAACS
- Clear elemental dose: 200 mg per two tablets
- Vegan, gluten-free, soy-free and non-GMO
- About $0.20 per 200 mg serving
- The label's full dose (400 mg) exceeds the 350 mg upper limit for supplemental magnesium
- Large tablets that some people need to split
- No USP or NSF certification
- Grogginess or loose stools reported by some at the full dose
Vitamin D3 2000 IU Softgels
- USP Verified for ingredients, potency and manufacturing
- 2,000 IU of D3 is half the adult upper limit
- About $0.06 per day
- Small softgel with an oil base that supports absorption
- Gelatin shell, so not vegetarian
- Soybean oil base may not suit people avoiding soy-derived ingredients
- No vitamin K2 for those who want a combined formula
Our verdicts
High Absorption Magnesium (Lysinate Glycinate)
A well-tolerated, clearly labeled chelated magnesium at a fair price, and a sensible first choice for people who found magnesium oxide or citrate hard on the stomach. Start with one 200 mg serving rather than the label's full 400 mg, and expect large tablets.

Vitamin D3 2000 IU Softgels
For most adults who want a daily vitamin D supplement, this is the benchmark: a sensible 2,000 IU dose, USP verification and a price that is hard to beat. Vegetarians should choose a gelatin-free option, and people who already have adequate levels should not expect broader health effects.
