Calcium gluconate is a synthesis of calcium and gluconic acid. It is classified as a calcium salt, meaning that it is soluble in water.


Serving Size & Timing

The FDA suggests that Calcium be taken in installments of 1000mg per serving, once or twice per day for healthy adults. It is recommended that this supplement be taken with meals. Calcium Gluconate is made up of about 8.5-9% pure Calcium. This means two servings of this size should be taken per day.

This Calcium Gluconate concentration is pharmaceutical grade and has no fillers whatsoever. It comes in a resealable bag and is meant to be stored in a place free from heat, moisture and light.


No serious side effects are associated with Calcium supplements, but minor side effects may be experienced with overdose, including stomach upset, nausea, irregular heartbeat, headaches and increased frequency of urination. Those who have medical conditions or are taking medications which alter the body’s ability to absorb Calcium are cautioned from taking this supplement, as it may exacerbate the condition or change the effectiveness of the drug. This supplement may inhibit the body’s ability to absorb the particular antibiotic tetracycline.


It is recommended that Calcium Gluconate be taken with Vitamin D supplements or in Vitamin D-rich juices, since this will increase its effectiveness and maximize its absorption. Of all of the forms of Calcium supplements, Calcium Gluconate is by far one of the most soluble in liquids and oils.

One of the largest sources of Calcium is in dairy, with just one small serving of dairy containing about 300mg, or 1/4 of the total daily value for Calcium. However, Calcium is also found in many other natural sources such as seaweed, nuts, legumes and quinoa.

Calcium gluconate isn't just calcium; it also helps with detox
I use Bulk's Calcium gluconate not just because it is an affordable way to provide calcium as part of the custom multimineral mix I make for myself, but also because the gluconate is a major help to my body's detoxing; taking the gluconate form of calcium is killing two birds with one reasonably priced stone. *

I bought this product because I need the purest quality Calcium Gluconate 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.*

most useful calcium for most people per RBTI Reams
The otehr views here are worth reading too.

I consider Carey Reams the Tesla of health. He invented drinking water with lemon juice for healing. One wisdom of Reams many people can apply is to to take calcium according to you pH. Most people are too acidic. Acidic people benefit by taking an alkaline forming Calcium. CA GLUCONATE IS THE ONLY WATER SOLUBLE ALKALINE calcium.

This means you don't need to ionize it with your own stomach HCl. Dissolved, it's already in ionic form.

Another Reams wisdom you can use is the Calcium ion is crucial for communication inside each cell. The practical result is Ca Gluconate can be EXTREMELY HEALING FOR WOMEN IF YOU ARE TAKING NO OR VERY FEW MINERALS. The more active your emotional inner life, the more gluconate seems to help cells communicate and the whole body work better.

PS: The other major water soluble minerals, especially relevant for people with low stomach HCl and/or the elderly, are Magnesium Chloride and Magnesium Orotate. Mg Orotate is avaialble in bulk at this site. *

Calcium Gluconate
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...*

Hard-to-Find Calcium Gluconate
Calcium Gluconate is difficult to find. How perfect that Bulk Supplements offers it, and at great prices!!! I cook with Calcium Gluconate every day! Our foods are so mineral deficient today, that Calcium Gluconate is a valuable nutritive addition to almost everything I cook. It is virtually flavourless, so I don't worry about the dish will taste. It just adds good nutrition and keeps my family and me healthy. Almost everyone would benefit from adding this highly soluble and quality calcium to your daily diet. *

Calcium Gluconate Powder
My application of focused use is in my modified version of the old, "Fortified Pep Up," drink formula, featuring an updated, wiser use of nutritional yeast, as opposed to brewers yeast, in which your calcium gluconate powder, has remained a contiguous ingredient for. I rate your product five stars overall on mixability both alone and overall, because the product is an uncomplicated compound to produce, and where taste is an irrelevant issue here, although I will remark that it tastes exactly as it did for me 40 years ago, and, as it correctly should be. Thank you for a reliable; quality product. Respectfully, J.G.C. *

Is this the same as Calcium D Gluconate? It doesn't list the "D" I'm used to seeing...
