I’ve been taking another brand of magnesium L-Theronate for about a year with some benefit but not very noticeable. I recently switched to this brand, the difference has been very noticeable…like WOW! I take 3 with dinner and now I’m sleeping deeply through the night, waking up feeling refreshed. My mind feels sharper too, more alert during the day. So glad I found this brand, it’s a winner. ## Features - HIGHLY BIOAVAILABLE FORM: Magnesium L-threonate is the salt formed from mixing magnesium and threonic acid, a water-soluble substance derived from the metabolic breakdown of vitamin C.
