As long as suggested serving sizes are adhered, to this supplement is safe to consume. Taking too much, however, may result in diarrhea and side effects such as indigestion, loss of appetite, weakness of muscles, low blood pressure, irregular heartbeat, respiratory issues and nausea.

Those who have experienced kidney problems in the past and those who are taking supplements or other products which already have high magnesium content should speak with a medical professional before taking this supplement.

If you are taking any medications over a long period, it may be best to consult a doctor before taking this supplement to determine whether magnesium carbonate will have an effect on these medications.


There are a few different groups of people that are at a higher risk for suffering magnesium deficiency. This list includes the elderly, people who use diuretics excessively and diabetics. Women who take pill-form contraception are also at risk. Since maintaining a magnesium-rich diet can be difficult, supplementation is often ideal for many individuals. It has also been shown that the efficiency of magnesium supplementation increases when taken in tandem with calcium. For best results, it is recommended that magnesium be consumed at a ratio of 1:2 with calcium.

If combined with a liquid high in acidic content such as lemonade or orange juice, this solution is highly soluble. It is considerably less so in water. The product should be stored in an area that is free from light, heat and moisture in order for the product to maintain its effectiveness and overall level of potency.

Magnesium carbonate is great!
Dissolves well! Just what I need for this vital nutrient.*

Very pure magnesium
this magnesium carbonate is very pure. I am so pleased with it, as it is affordable, very affordable for magnesiom. It will be a product that I will re order for sure.*

Great product!
I started taking Magnesium for digestive issues, along with Berberine HCL Powder and N-Acetyl L-Glutamine. I just started taking them but I will say just one night taking them worked really well! There are so many other benefits as well! I am hoping the Magnesium will also help with varicose veins and I will write another review on this in the hopefully near future. It took a while longer for my order this time but I do believe that was on the part of USPS and not Bulksupplements. I'm sure had I contacted BS they probably would have resent my order overnight! The are an amazing company with absolutely top quality supplements at the best prices around! *

Great product!
Reduces my stress level and symptoms, relaxes my muscles and my memory (I am close to 70 years young) has gotten a lot better since I started taking it. It softens the stool and promotes general well being ( in my humble opinion). *

Great Product - Magnesium Carbonate
I wanted to take this supplement for a while before I reviewed it because I had just finished a course of L-Carnosine. (Another great product!) I wanted to make sure that I was noticing some results from the Magnesium Carbonate after I had stopped using the Carnosine.

I began taking the magnesium carbonate the day that I received it. I have even gotten my wife to try it as well because she is a little low on magnesium. I recently began going to the YMCA to use exercise equipment MWF and I go to an arthritis swim class on T & TH. I haven't experienced near the muscle aches I had anticipated and it appears that the varicose veins in my legs have all but disappeared. I cannot give any one thing the credit but I do believe that the additional magnesium in my system is helping me in ways that I had never imagined. The exercise is great too.

I would recommend this product to anyone with muscle pain or digestive tract issues. I have IBS and almost continual issues with my gut. The magnesium carbonate helps with that as well. I take 1/4 teaspoon twice a day.*

Product Review
My first purchase from Bulk Supplements. Very impressed with the freshness of the product & fast shipping. Will recommend this company.*

Magnesium Carbonate
This product has made such a huge difference in my life. I am allergic to magnesium stearate so this is a way that I can supplement magnesium without added ingredients. It relieves anxiety and fatigue without undesirable digestive side effects. Highly recommend this product!!*

On 7/19/2016 Jill said...

I bought this product because I need the purest quality Magnesium Carbonate for a perfect cal-mag formula. I measured the amounts needed and mixed and the result was exactly as expected. The quality is as perfect as it needed to be. I am satisfied. Also, I am amazed that there is still a company that makes such a wide variety of supplements and for so many purposes. I will keep coming back as long as they offer.*

Magnesium Carbonate
This is one mineral of many needed for a purification program that is well known by L. Ron Hubbard, "Clear Body Clear Mind" and is an essential product(s) for this purification program. This product is unavailable in in it's pure and bulk form from any Health Food Store. I will be purchasing other products from that are especially designed for this program and other supplements to maintain a good and healthy well being.I did a random search for this product and others and found this site.

Thank you BulkSupplements......ordering again soon...Oh and thanks for the free sample of Niacin...*

Calcium Carbonate
I'm very pleased with both the price, prompt delivery and quality of this product. It is a very fine-powder that mixes well into drink mixes. *

Buy in bulk, mix your formulas and make your supplements, when you buy in bulk, your money goes farther *

All purpose product
I use this product for magnesium supplementation and have also found that it works as a great main component of homemade toothpaste. I drink a lot of tea and this toothpaste is easily the most effective natural toothpaste I have used for keeping my teeth white and feeling super clean. I found that as a supplement i seem to absorb this form of magnesium just fine, and occasionally mix it with lemon juice or another acid like vitamin c, and find that it does react, possibly forming additional forms of magnesium such as magnesium acetate and/or magnesium ascorbate. *

As I've experienced before, Bulk Supplements Rocks! I received this after reviewing a previous order and as the previous order was everything I hoped for, so was this one! Even got my Dad ordering from bulk supplements! *

Finally ... Supplements that Make Sense!
I was always baffled that while supplements are hailed as being "good for you," the supplements that you find at your typical grocer or pharmacy are full of artificial this and artificial that. Many of the choices at your typical health-store are not that much more pure.

Then, along came BulkSupplements! Finally ... Supplements that Make Sense!

I add this supplement to either the olive-oil mayo that I put on top of a hard-boiled egg or in my yogurt-fruit-spread combination -- with an interesting change to the flavors that I really like!

Thank you, BulkSupplements, for doing the right thing!*

Magnesium Carbonate
I wanted a form of magnesium that wasn't going to increase iron or sodium levels in the diet. Bulk Supplements offered the best product I could find. It is packaged very well in air tight, sealed bags and it has always shipped immediately. The one time there was a mix-up, they shipped my order overnight for free. I recommend their service and products*

High Quality
High quality product. Magnesium is crucial for electrical impulses through the heart. Helps ward off PVCs*

Best Magnesium I've ever tried.
I take this product twice daily, to relieve muscle aches and pain due to working out. On occasion, my 9 year old daughter has also taken this form of Magnesium, after an intensive gymnastics class. My preferred method of consumption: 1/4 teaspoon dry powder placed on the tongue and swallow it down with water. The Magnesium Hydroxide powder, also sold by Bulk Supplements, has an off-putting, fishy taste and tends to cause diarrhea. This Magnesium Carbonate powder has next to no taste at all and doesn't seem to have any adverse side effects. This powder is white in color and is similar to cornstarch in consistency. Because of its fine powder grade and remineralizing properties, I've been using this magnesium powder to brush my teeth as well. I am very pleased with this Magnesium Carbonate, will purchase again and would recommend to anyone. *

I am impressed!
I love this company and it's products. This magnesium has been great for my stomach. It has been a great addition to my regime, especially for those powders that are known for irritating the gut. Thank you Bulk Supplements!*
