Magnesium Citramate™
Price: Calcium Citramate™
Size: 90 capsules

Calcium in the most abundant mineral in the body. Calcium can be very hard to absorb through the intestinal tract. Because of this, many animals are marginally deficient in calcium.

If your dog or cat is eating a home cooked, with a significant amount of meat in the diet, calcium is the most important mineral to add to the diet. Calcium Citramate[[trade]] is far superior to bone meal for these animals.

Calcium Citramate[[trade]] (Citrate-Malate) has demonstrated superb solubility and superior absorption when compared to other calcium salts. It has approximately six times the solubility of either calcium citrate or calcium malate individually.

The most common form of calcium, calcium carbonate has very poor absorbability and alters the body's acid/base balance.

We believe that, for many animals, Calcium Citramate[[trade]] is the most cost effective and useful calcium supplement available.

    An optimal diet should contain a calcium to phosphorus ration of roughly 2 parts calcium to one part phosphorus.

    Home prepared diets often contain larger amounts of meat than commercial diets. We believe that this is often a good thing for carnivores (dogs, cats and ferrets), but meats are very high in phosphorus and very low in calcium. This alters the calcium phophorus ratio, ending up with too much phosphorus and not enough calcium.

    Often published recipes recommend bone meal, because bone meal has the optimal calcium to phosphorus ratio. These recipes fail to take in to account the high phosphorus in the diet. The result is excess phosphorus in comparison to calcium.

    The solution is to simply feed a calcium supplement that contains no phosphorus, such as Calcium Citramate[[trade]].

    We believe that, for many animals, Calcium Citramate is the most cost effective and useful calcium supplement available.

    Calcium supplements in birds

    Some veterinarians recommend providing calcium by placing calcium gluconate in the water. We do not recommend this because the amount of calcium in this product is very low and birds don't absorb enough calcium from this water based supplementation.

    Calcium Citramate[[trade]] is a far superior calcium supplement for birds, when compared to calcium gluconate.

    To highlight the small amount of elemental calcium in calcium gluconate lets look at an example. Calcium gluconate comes in a 10% solution, which is diluted and placed into the water bowl. A 10% calcium gluconate solution means that there is 100 mg of calcium in one milliliter (one milliliter is roughly equivalent to 1 or 2 capsules or tablets of calcium. But, since elemental calcium only makes up one tenth of the entire milliliter of calcium gluconate, there is actually only 10 mg of calcium in that milliliter of calcium gluconate!

    After its dilution in the water and then following the poor systemic absorption (a common problem with all calcium supplements), it is likely that the average bird is receiving far less than 1 mg of calcium daily!

    This is an insignificant amount when compared to the amount of calcium naturally availble in the foods a bird eats each day.

    Calcium Citramate[[trade]] is a far superior calcium supplement for birds.

    • Animals that are on a muscle meat and organ meat based diet (see our information on how to easily feed a well balanced fresh food diet to your dog (Feeding Your Dog) or your cat (Feeding Your Cat)
    • Animals that are on home cooking diets; especially when the animal is a finicky eater that refuses to eat the entire diet (these animals often end up eating primarily muscle meats
    • Animals on food trials for allergies
    • Animals fed a limited diet, especially when the diet is almost entirely meats. These animals should also be fed Canine Sports Basics, olive oil or coconut oil and Super EPA
    • Animals on limited antigen or hypoallergenic home cooked diets
    • Birds: Most birds do not receive enough calcium in their diets
    • Lactating mammals


    • 1 capsule for each 25 lbs daily, mixed into the food


    • 1/4 daily, mixed into food


    • Sprinkle 1/4 capsule on soft foods (foods that the calcium powder will adhere to), once or twice daily... this dosage assumes a fair amount of wastage as the foods are rarely completely consumed.


    • 1/4 daily, mixed into food


    • Feed by mixing into thier foods, 1/8 to 1/4 capsule on the food twice daily. Snakes that are eating dead mice, rats or rabbits, can have the calcium capsule placed into the dead animal and then feeding that animal to the snake.

    Each Capsule Contains:

    Calcium (as Calcium Citrate Malate)

    160 mg

    Malic Acid (Approximately from Calcium Citrate-Malate
    265 mg

    Other ingredients: Cellulose capsule. May contain one or more of the following hypoallergenic ingredients to fill space-Leucine, Silicon Dioxide.
