Calcium/Magnesium question again

[Guest guest]

Hi,

Just like to make sure I am doing the right thing.

There was a fair amount of posting on this supplement but I did not get

one

important point and I'd like to ask it again:

Is the recommended amount of Calcium/Magnesium 1000mg/500mg per day for

our

kids? Is this amount to be used for the pure elemental weight?

Eg I am using a Calcium and Magnesium Amino Acid Chelates tablet.

It says 500mg Calcium Amino Acid Chelate (100mg Calcium) and 250 mg

Magnesium

Amino Acid Chelate (50 mg Magnesium).

If we take the molecular weight as a guide, we need 2 tablets per day.

But if we take the elemental weight, we need 10 tablets a day.

I just find it a bit much to take 10 tablets a day, so I got confused.

I know there will be some of these in food as well. So is the

recommended doze

given for the supplementation or for the total?

Also, if there is an overdozing could it contribute to kidney stones or

any

other problem over time?

, sorry if you have already answered this question.

Thanks for any answer,

Elvira

Hi Elvira,

No problem posting this again. I looked high and low to find out this

exact answer because it makes a huge difference in the amount of

nutrient you are getting. Look for the parethesis. The FDA requires

that the exact amount of nutrient provided be listed in the

parethesis on the label. The form the nutrient comes in is important

in determining how soluble or available the nutrient will be in the

body.

In your example, 500mg Calcium Amino Acid Chelate (100mg Calcium)

will give you 100 mg of elemental Calcium. The molecular weight of

the entire chelate would be much higher. The magnesium Amino Acid

Chelate (50 mg Magnesium) would provide 50 mg of Magnesium. If I had

a brand that said Magnesium Oxide (50 mg) then I would also get 50 mg

of mag from that source. However, because that source is not as

available, my body may not be able to use all of that 50 mg whereas

it could use all 50 mg of the mag as a chelate. The chelated forms

are very good.

> Also, if there is an overdozing could it contribute to kidney

stones or any other problem over time?

As far as I can tell, you need to take a large amount of calcium over

a very long time. At least 2,000 mg/day is given as the top limit for

cal/day.

.

8. The All- Important Parenthesis!

Following the ingredient name should be a parenthesis giving

information about the form, chelating agent or source of that

nutrient. If there is no information in parentheses, the actual

amount of that element is less than what is stated. What is being

stated is the weight of the compound, not the amount of the nutrient!

For example, a 600 mg tablet of " calcium " with no following

parenthesis is in fact only about 130 mg of elemental calcium. A

listing of " calcium (as calcium citrate) " means you are getting the

full amount of elemental calcium listed on the label.

FDA has received many inquiries over the years that questioned

whether amounts specified on labels refer to the weight of a

particular nutrient or to the salt of

that nutrient used to make the supplement. Having parentheses around

the source compound makes it clear that the quantitative amount and %

DV pertain to the dietary ingredient listed and not to the source.

Thus, FDA concludes that the format that it proposed is the most clear

and should not be optional.
