Magnesium L-Threonate 100g Powder

(10 customer reviews)


Magnesium is an important element in brain function and memory. Increasing brain magnesium can enhance both short-term and long-term memory and improve learning especially as we age. It also acts as an antioxidant and is important in many other processes.

Magnesium L-threonate, unlike more common forms of magnesium, is believed to be more effective in increasing brain magnesium due to it’s ability to cross the blood-brain barrier.

Magnesium L-threonate is used for:

  •       Improved short and long-term memory
  •       Cell protection & antioxidant
  •       General wellbeing.

Suggested use: 1000-2000mg per day divided into 1-2 doses. (e.g 1000mg 2 times a Day)

1000mg of Pure Magnesium L-threonate provides approximately 72mg of Magnesium.

If you don’t have scales, Mag-L Threaonate weighs about 0.65g/ml so 1/3 teaspoon is around 1g (1000mg) or 1/4 tsp about 800mg.

    I had heard this works well for anxiety, memory and sleep and does not cause stomach distress. So far both my husband and I have noticed falling asleep quicker and better quality of sleep.

    f you struggle with sleep issues, try taking them before going to bed. Since starting these I am getting the best sleep I’ve had in years! I will be supplementing with these for life.

  5. Aiden Twopeny

    I have a couple of different heart arrhythmias that were into the dangerous range. I tried one prescription medication and it worked for a couple of days, and then quit working and had bad side effects. My Cardiologist suggested I try Magnesium Threonate, since he has had other patients who have been helped by it, and we are trying to avoid me having to have an ablation. So, I bought this, and it works very well for me. I have been taking it for several weeks, and it has greatly lessened my episodes of arrhythmias. And I have only been taking a low dosage so far, because I am always sensitive to anything I take, so I always go slowly. The cardiologist wants me to slowly up my dosage to hopefully totally eradicate the arrhythmias entirely. This product has changed my life for the better in a huge way.
