Hmm, that does seem like quite a bit. At that rate, 1kg will only last you ~23 days as well. Perhaps the lower doseage will give you the improvement. Please let us know how it goes.
My MgT arrived a few days ago from Orchid and I am still nervous about the dosage.
Slutsky in his paper ‘Enhancement of learning and memory by elevating brain magnesium’ www.ncbi.nlm.nih.gov/pubmed/2015212k
said ‘We found that 50 mg/kg/day (elemental Mg2+) is the minimum effective dose’.
I am a 162 lb | 70Kg man and scaling up means 70Kg x 0.05g/day = 3.5g/day of elemental Mg/day. The FDA suggest a minimum of 0.4g/day of magnesium and I am proposing to take nearly 9 times that much.
The molar mass of MgT is 294.5 g mol-1 en.wikipedia.org/wiki/Magnesium_L-threonate and the atomic mass of magnesium (Mg) is 24.3. Hence I calculate my daily dosage of MgT to be 3.5g/day x 294.5 / 24.3 = 42.4g/day | 1.5ozs/day. This is a scary amount when you actually see it weighed out and at the moment I am on half dosage checking to see if there any side effects.
I would certainly welcome comments
Do keep in mind that rats aren't humans. And lesser dosages doesn't mean they didn't have any effect, but just that it wasn't enough to be measurable through indirect methods. Rats can't speak, unfortunately!
I'd suggest you use small doses - use the first day a dose of 1g or smaller - you can dissolve it in a glass of water, it has no taste.
Make sure your heartbeat is regular, and that your blood pressure doesn't drop (you'd become pale, heart rate would go up, etc.) It is an experimental compound, so always be extra cautious, even if it may not seem necessary. I had someone with me in case I reacted poorly to the compound - although it was highly unlikely, better safe than sorry.
I'm currently researching a bit more on the optimal dosage and the different effects, but I won't have time until Monday to go in my university to access some research papers.
I have some reasons to believe that MgT affects the learning process - it's somewhat of an intuition that emerged while reading different articles - and somewhat of a personal experience - it may be a subjective feeling, but a couple of articles interesting points concerning the learning process and memory in rats (in regards to some potent -racetams), how they measured it, and the physiological effects while studying slices of those rats' brain.
Still, there's lot of research to be done because the data is very scarce on the cognitive effects of higher Mg+ concentration on a healthy adult brain. Basically, lots to make from scratch.

Your reasoning is also flawed although the answer is okay (based on the assumption this conversion is correct which isn't the cse)
(g/day) * [(g/mol) / (g)] doesn't make a (g/day) answer. There's a mol 'part' you haven't eliminated.
1 mol of MgT = 300g (very roughly)
1 mol of Mg = 25g
If you want your body to have 50g of pure Mg (2 mol), you'd have to take 2 mol of MgT. That means 600g of MgT.
Let's divide all this and get milligrams. 50g = 50 000 mg, so we divide by 1000. If you need 50mg of pure Mg, you have to take 600 000/1000 so 600mg of MgT per kilo. You multiply by 70 --> 7*6 = 42, you add 3 "0"'s and you get 42000mg, or 42g. So, good answer (again, on the wrong assumption), bad reasoning.
Anyway, do check this paper dealing on conversion factors for human and different animals.Since you can't convert dosages that way - let's proceed to a better way.
So, let's multiply he 50mg/kilo by 6 - a factor for rats. 300mg/kilo. We now divide by the factor for humans (37). 300mg / 37 which should be around 8,1mg/kilo for humans. Multiply that by 70kg, assuming that's your weight and you'd need around 567mg of Mg.
Mg represents 1/12 of MgT's weigh so we multiply by 12 -
you'd need a bit less than 7g of MgT daily.Can anyone double-check my calculations - just to be safe. I also did them in my head, but dealing with such conversions is already very tricky that such gross inaccuracy can be excused ;-)
[...]However, the Food and Drug Administration (7) has
suggested that the extrapolation of animal dose to
human dose is correctly performed only through normalization
to BSA, which often is represented in mg/
m2. The human dose equivalent can be more appropriately
calculated by using the formula shown in Fig. 1.
To convert the dose used in a mouse to a dose based on
surface area for humans, multiply 22.4 mg/kg (Baur’s
mouse dose) by the Km factor (3) for a mouse and then
divide by the Km factor (37) for a human (Table 1).
Table 1
(Weigh kg) (BSA m²) (Km factor)
Human
Adult 60 1.6 37
Child 20 0.8 25
Baboon 12 0.6 20
Dog 10 0.5 20
Monkey 3 0.24 12
Rabbit 1.8 0.15 12
Guinea pig 0.4 0.05 8
Rat 0.15 0.025 6
Hamster 0.08 0.02 5
Mouse 0.02 0.007 3
Formula:
Human DOSE = Animal dose (mg/kg) * ( (Animal Km factor)/(Human Km factor) )
