Amazing magnesium L-threonate
There is no doubt that Magnesium L-threonate is the best form magnesium but it is bit costly than gluconate,but it is worth of buying. For better results need to take 4-5 capsules a day because elemental magnesium contain is only 144 mg and for adults more than 400 mg per day is required.

Expensive but worth it
This is really expensive but magnesium threonate usually is. And it works. I feel calm, sleep well and feel more efficient. Can’t say for certain that it works on the brain but this magnesium supplement helps with that. I wish it was cheaper, it’s 2-3x of other mag forms. Reduced one star for that

Best thing for brain.
Good product for Brain. Value for money. I bought this instead of other brands due to better pricing , Absorbency level is good. Seller globalmartindia is better choice.

Miracle happens!
It works! Best when I take it, after a good night's sleep. For enhanced focus/concentration drink coffee after taking this, at least that is how it works for me. However, when sleep deprived taking this supplement gives the opposite effect and feel more sleepy.

Better for taking in the day

Was initially impressed that this product seemed to work with other supplements to slightly boost my intuition, unfortunately that initially also came with quite severe headaches and blood pressure issues. I have since traced the side affects to either excess B12 supplements in my diet or excess total magnesium due to another form of magnesium that I was also taking at the same time (after discontinuing both I was able to gradually get used to this form of magnesium). Just keep in mind that if you have blood pressure issues / severe headaches shortly after taking this for a short time it may possibly be linked to this product / other dietary adjustments may be required.

Paid 43 euro/90 capsules and the product looks suspiciously low quality at first inspection. A lot of the content just spiled outside the capsule into the container.

It makes such a difference in memory and cognitive function.
