Magnesium

Postby Alex on Sat Jul 18, 2009 5:59 pm

Interested in where anyone is getting their magnesium from and in what form if supplementing seperately from zinc. Powder would be preferable as it appears to be far more economical.

Found one source for citrate so far but wouldn't mind alternatives.

I don't supp with it but I just googled magnesium citrate powder and there are loads of places to buy it from.

Most are cap form though and/or pricey. Also they don't specify the extract % of magnesium from the citrate in most cases which is why I'm asking for known sources.

why do you prefer to supplement separately with zinc?

To be honest if diet is clean and contains plenty of veg, fruit, nuts, whole grains and sea food I don't think extra magnesium supplementation is necessary.... you can exceed the 400mg RDA by just eating a generous portion of spinach and a large handful of nuts (although to be fair RDAs are closer to the minimum requirement then to the optimum).

From what I've read, athletes have a much higher need for magnesium.
Personally I use NOW Foods magnesium and sodium at the moment. First time supplementing with magnesium except for a run with some MP stuff way back when I was trying to spend everything I had on all sorts of supps.

or

http://purebulk.com/magnesium-gluconate

gluconate is more boiavailable but there it has a lower elemental %

yes. Shit hot service, delivery is relatively cheap and they generally mark it as a gift.

I usually get a kg of citrate and 1/2 kg of zinc gluconate.

Think i'll be placing an order.

How are you dosing them both? I'm thinking maybe 2 doses of 30mg Zinc early in the day and 2 doses of 1g Mag in last 2 meals. Quantities being elemental.

Ah, would make sense and explain why I couldn't find them. Has SN changed too as couldn't find them either but may have been my spelling.

Yes you are right - although i think a genuinely clean diet is still going to give an athlete enough mg. I worked it out that just through my diet alone i get roughly 1100mg a day already. Extra mg may possibly be of greater benefit - and of course not all that is consumed is bioavailable, but with a diet providing this much already it could only be a low priority supplement when on a limited budget.

The Journal of the international society of sports nutritions stand point on magnesium -
Dietary Supplements and Sports Performance: Minerals
Magnesium


Magnesium is a component of over 300 enzymes, some involved in the regulation of muscle contraction, oxygen delivery, and protein synthesis. Several studies have investigated the effect of magnesium supplementation on performance. Lukaski noted that some earlier studies have shown that magnesium supplementation improved strength and cardiorespiratory function in healthy persons and athletes, but also noted it is unclear as to whether these observations related to improvement of an impaired nutritional status or a pharmacologic effect [14,15]. Lukaski also noted that the study designs limit conclusions about dietary recommendations needed to optimize performance. Newhouse and Finstad [16] also noted that interpretation of the available studies was confounded by differences in research design. Nevertheless, in their meta-analysis of human supplementation studies, they concluded that the strength of the evidence favors those studies finding no effect of magnesium supplementation on any form of exercise performance, including aerobic, anaerobic-lactic acid, and strength activities.

I think zinc supplementation is far more important tbh as its much harder to get from food.

1/3 to 1/2 g of zinc gluc every morning (so 43 - 65mg elemental per day)

3g mag citrate at night (so 450mg elemental) Plus 1g after every workout.

What about magnesium asporotate? (Magnesium Aspartate, Magnesium Citrate, Magnesium Orotate)

What's so bad about taking zinc and magnesium together?

lol, Isn't magnesium citrate a laxative?

A good link here comparing the bioavailability of magnesium salts - Magnesium - bioavailability, pharmacokinetics.

The above suggests magnesium L-lactate dihydrate is the best, but it looks hard to get in the uk - although found this from a US store Mag-Tab SR

Yes it is.

Thanks for the bulkpowders links. Time to persuade my bro to place an order so he can send it on from the UK. Customs here have taken to seizing everything from the States.

Nice links Det.

I use these http://yournutritionshop.co.uk/shopexd.asp?id=2842

Nothing wrong with taking Zinc and Mag together,however,i believe,amongst the benefits of taking them at seperate times are -

Zinc AM(away from dairy) - AI properties

Mag PM - Split over final 2 meals,calming and aids sleep.

Thats really expensive for mag citrate, 150mg * 180 = 27g. 27g for a tenner is extortionate.

zinc and magnesium are prob the most important supps when training imo as theyre depleted easliy and are the most common deficiant minerals in most peoples modern diets for price some zinc gluc tabs and mag citrate powder are the best bang for your buck imo

What form of magnesium did you go for Alex?

Been reading more about magnesium and really speaking should revise some of what I said earlier in this thread.

Typical intake for most people is actually going to be woefully low... just been looking at fairly standard diets (for mineral intake) and most people might just about scrape the rda of roughly 200mg, but that isn't going to cut it if you workout, with a more appropriate daily amount being around 600mg... and you can double that if you smoke.

Had been estimating my own intake was well in excess of this (due to eating lots of spinach, nuts and appropriate sea food) and while it does come in above rda, around 400-500mg a day, it's not as high as I thought it was and certainly not enough for optimum.

Am gonna start supplementing with magnesium (and zinc) in a month or two and think it's an area where its worth paying more to get a good bioavailable product... will probably get some of the magnesium L-lactate dihydrate sent over from the states - looks the best one.
