Does anyone know if citric acid in a supplement mean it is corn derived?

I know "citric" implies fruit but what is it really?

Usually citric acid is made from corn. Does not have to be.

Thanks, and I have another few questions.

Is calcium citrate and magnesium citrate related to corn products?

What creates the "citrates" in those minerals?

if not corn derived it most certainly would state so, to make you aware as consumer........
I haven t been properly introduced to NOT corn derived citric acid yet!!!

maybe in another life, if lucky!! ;D

In the USA, citric acid almost defintily means corn unless it's otherwise specified. I recall seeing something normally corn-derived listing tapioca or some other source on the label of a "kosher for Passover" item recently, but I can't remember if it was citric acid or somethign else, what product it was, and if I bought it or put it back on the shelf.

I'm not sure about the citrates in the minerals. Try emailing the supplment companies directly.

Magnesium citrate is an ingredient in just about every single one of the DPN formulas.

I will have to email them.

Calcium Citrate and Magnesium citrate are both salts of citric acid.

I think it is usually made by reacting Calcium (or Magnesium) Carbonate with Citric acid to form Calcium (or Magnesium) citrate.

Quoted from Ad for Natural Calm describing Magnesium Citrate

Magnesium citrate is the active ingredient in Natural Calm. Natural Calm is made up of two ingredients; Magnesium Carbonate and Citric acid. Magnesium citrate is produced when Natural Calm's two ingredients are combined with hot water. The addition of hot water causes the carbonate in the magnesium carbonate to "fizz away" and the magnesium to combine with the citric acid producing magnesium citrate. The magnesium content of magnesium citrate corresponds to about 11%. The amount of citric acid added to Natural Calm is proprietary and is designed to enhance bioavailability. Magnesium (and all minerals) need to be in an acidic environment for the magnesium to be absorbed and Natural Calm has an ideal acidic content to allow for maximum bio-availability.

Magnesium citrate works best on an empty stomach ideally half hour before bed as food will dilute the acid content and reduce the absorbability. It is designed to be taken with 8oz (240ml) of water. Natural Calm Magnesium Citrate can be taken hot or cold but needs at least 1 oz (30 ml) of hot water to dissolve, then you can add more hot or cold water and enjoy. Natural Calm Magnesium Citrate has a citrus taste and most people find it pleasant. ...

Magnesium Citrate is Alkalizing

After passing through the stomach (and stomach acids) and being hit with enzymes, what's left is an alkaline ash and the net result is that Natural Calm magnesium citrate is alkalizing to the body. Think of fire wood being burned up, what is left after the digestive fire? Citric Acid is a "weak" acid that is easily eliminated via sweat and respiration. It is alkaline forming in that it stimulates the formation of magnesium carbonate in the body. Magnesium carbonate then neutralizes the "strong" acids in the body, acids that can only be gotten rid of through urination, including uric acid which is the end result of protein metabolism. So Natural Calm Magnesium Citrate is the perfect pH balance to enhance the absorption of magnesium and alkalizing the body.

Magnesium Citrate Has Two Main Functions

Magnesium citrate has two main functions; one to restore magnesium levels to an optimal level, the second is to help keep you regular. Once your body absorbs what it can, it puts the rest into the colon. The Magnesium citrate works by attracting water through the colon's tissues by osmosis. Once in the intestine, it attracts water into the intestine to induce defecation. The additional water helps to create more feces, which naturally stimulates bowel movement. This means it can also be used to treat rectal and colon problems. Magnesium citrate is generally not a harmful substance, but care should be taken to consult with a health professional if any adverse health problems are suspected or felt.

The optimal amount of magnesium citrate to take is where your bowels are comfortably loose. Natural Calm magnesium citrate should never be taken long term as a substitute for a poor diet.

I can usually take magnesium citrate without problems (although it is not my preferred form of Magnesium), but I do sometimes seem to have adverse reactions to citric acid as an ingredient in foods.

I have emailed them today asking for the source of those citrates. Will share that here when they
get back to me.

calcium citrate was a preferred form of calcium, according to old threads by Heidi

calcium carbonate was best avoided....

however the calcium from the sea by DPN is best

citric acid used in the sup industry is a popular conservative

there is no citric acid in any sup by DPN......
the citrate form is considered safe and all sups have Dr D s ok/

Citric acid does not automatically mean corn, though most citric acid in the US is produced from GMO corn. Citric acid, besides naturally occurring in fruits, can be derived from sugar beets too.

if not stated, ´´beet´´ or ´´natural occurring´´ then you can beyond unreasonable doubt confirm it is corn derived and GMO :)

Are you sure that is magnesium citrate & not magnesium stearate?

The current D'Adamo products should no longer contain magnesium stearate, but a number contain magnesium citrate.

Aaah thanks... So is that magnesium from corn?

Chloe was going to check whether it was was corn free or not.

I see 'ascorbic acid' listed in my pineapple juice.  Is that the same as citric acid and, if so, I can assume it is also from corn?

Lola states in reply 10-20, from 2011 that there is no corn in any of DPN supplements....I never got a reply back from NAP when I contacted them in 2011.  This thread was inactive for a long while.  

I would trust Lola's reply and assume magnesium citrate in any of DPN formulas are corn free. I'm pretty
sure Dr. D would not want corn sensitive individuals, including his own patients to be consuming corn.

Ascorbic acid is often derived from corn, it does not have to be.

Thanks, C-Sharp.  I'll have to do some investigating.

It really irks me that they can put "100% juice" on the label when they add corn-based ascorbic acid. Ascorbic acid is not citric acid; ascorbic acid is a form of vitamin C. However, it's usually corn-based in the USA, and I can't consume any products containing "ascorbic acid" without becoming ill (although it's a rather subtle reaction, and it's not the only thing that keeps me from feeling energetic and healthy.)
