Consumer advice
This is a legitimate, well-formulated product. If you're already a patient at Aim For Wellbeing or prefer the Pure Encapsulations brand for its quality controls and hypoallergenic formulation, this is a fine choice. However, if cost matters, Doctor's Best or NOW Foods Magnesium Glycinate offer the same chelated form at roughly half the price. Effective dosing is typically 250–400mg elemental magnesium daily — at 120mg per capsule, you'd need 2–3 capsules per day, which is within the labeled range (1–4 caps). Check your total dietary magnesium intake before supplementing, and note that magnesium can cause loose stools at higher doses.
