Thorne Magnesium Glycinate vs Aursen Supplements: Which One Is Actually Better? (2026 Honest Review)

---

1. Why We Wrote This Comparison

Thorne is one of the most recognized supplement brands in the United States. Trusted by professional sports teams and recommended by healthcare practitioners, it has built a strong reputation in the supplement world.

But reputation alone does not mean a product is the best value for everyday Americans looking to improve their sleep, reduce anxiety, and support their overall health with magnesium glycinate.

So we put Thorne Magnesium Glycinate head-to-head against Aursen Supplements Magnesium Glycinate — and the results surprised us.

Side-by-Side Comparison

3. The Biggest Difference: Dosage

This is where Aursen Supplements clearly wins.

Thorne Magnesium Glycinate delivers just 120mg of magnesium per capsule. To reach the clinically recommended daily dose of 300 to 400mg of elemental magnesium, you would need to take 3 to 4 capsules of Thorne per day.

Aursen Supplements delivers 275mg per serving — meaning most users only need one serving to support their daily magnesium needs. This is not just more convenient, it is significantly more cost-effective.

4. Price Comparison: Which Gives Better Value?

Thorne Magnesium Glycinate retails for around $43 for 90 capsules. At a therapeutic dose of 3 capsules per day, that bottle lasts just 30 days — costing you $43 per month.

Aursen Supplements Magnesium Glycinate offers a higher dose per capsule at a more competitive price, with free US shipping on orders over $50. That means more magnesium, less spending, and no delivery costs.

5. Quality and Testing: Are They Both Safe?

Both Thorne and Aursen Supplements take quality seriously — and this is one area where they are genuinely comparable.

• Both products are third-party tested for purity and potency
• Both are manufactured in GMP-certified facilities in the USA
• Both are vegan, non-GMO, and gluten-free
• Both use chelated magnesium bisglycinate — the most bioavailable form

The difference is that Aursen Supplements backs this up with 2,847 verified 5-star reviews from real customers, and offers a full 30-day money-back guarantee — something Thorne does not match.

6. Which Is Better for Sleep?

Both products use magnesium glycinate — the form most commonly recommended for sleep support. The glycine amino acid attached to magnesium activates calming GABA receptors in the brain, helping you wind down naturally without the grogginess associated with melatonin.

However, because Aursen Supplements delivers 275mg per serving versus Thorne's 120mg, users are more likely to reach the therapeutic dose needed for meaningful sleep improvement — without doubling or tripling their capsule intake.

7. Which Is Better for Anxiety?

Research consistently shows that magnesium deficiency is linked to heightened anxiety and stress sensitivity. Restoring healthy magnesium levels helps the body regulate cortisol and supports a calmer nervous system.

The higher dose per capsule makes Aursen Supplements the more practical choice for people using magnesium glycinate specifically for anxiety and stress relief. You get more magnesium per capsule, at a better price, with less guesswork around dosing.
