Finding the Right Calcium Supplement for Your Dog

Finding the Right Calcium Supplement for Your Dog

What Is Calcium?

Calcium is a mineral that plays numerous important roles in your dog’s body. It is probably most well-known for being a major structural component of teeth and bones. However, it performs several other important functions, as well.

In addition to helping build strong bones and teeth, calcium is important for digestion, nerve function, muscle building, and blood clotting. It also supports contractions in the heart muscle, keeps your dog’s nails and coat healthy, and helps with hormone secretion.

The Role of Calcium in Your Dog’s Body

Your dog’s body cannot produce calcium. Instead, it must be consumed through the diet, such as through food and supplements. Over 98% of the calcium in your dog’s body is stored in the bones, where calcium is deposited and withdrawn when needed. This means that when a dog isn’t receiving enough calcium in their diet, the body will take calcium from the bones to compensate.

Having calcium stored in the bones helps keep the body functioning properly; however, calcium shortages can start to negatively impact bone health, weakening the bones and even leading to bone disorders. It’s important that dogs receive a healthy amount of calcium through their diet.

A Delicate Balance

Ensuring your dog is receiving the right balance of calcium is essential for overall health. Too much calcium can cause kidney failure and hypercalcemia, while not having enough calcium can lead to hypocalcemia. This is why it’s important to know when it’s best to give calcium supplements to your dog and when you shouldn’t.

Calcium requirements vary depending on factors including age, breed, genetics, and overall health. For example, dogs that are nursing often have higher calcium needs. If these needs aren’t met, a life-threatening condition called eclampsia can develop. You should consult with your veterinarian to ensure your dog is receiving an adequate amount of calcium in his diet.

If your veterinarian determines that your dog could use a calcium supplement, finding the right supplement is key. Not all calcium supplements are created equal!

Thomas Labs® Calcium Now

In order to meet the needs of calcium-deficient dogs, Thomas Labs® created Calcium Now, a fast-absorbing, oral calcium supplement. It contains three forms of calcium to ensure it is easily and rapidly absorbed, and it is fortified with essential minerals and antioxidants to ensure it is completely absorbed.

Calcium is an interdependent mineral, meaning it works in synergy with other minerals to ensure it works to its full effect and delivers all its benefits. If you’re looking for a calcium supplement for your dog, keep an eye out for the following ingredients!

Calcium Carbonate: Calcium carbonate is a dietary supplement that is often used when there isn’t enough calcium in the diet. Calcium helps with the control and release of glucose in the bloodstream, which is used by the muscles for fuel.

Calcium Lactate: This form of calcium is bound to lactic acid to provide calcium even in gastric environments with low acid. This form of calcium is easily absorbed.

Calcium Ascorbate (Vitamin C): Vitamin C enhances the absorption of calcium. One of vitamin C’s most vital roles is in the production of collagen, an important cellular component of connective tissues, muscles, tendons, bones, teeth, and skin. Ascorbic acid works synergistically with vitamin E, meaning that both nutrients work more effectively together to extend their antioxidant effects.

Magnesium: Magnesium is necessary for calcium absorption and utilization. It also aids in the absorption of vitamins C and E, phosphorus, sodium, and potassium. Magnesium and calcium are responsible for maintaining a healthy bone mineral balance. Without enough magnesium, calcium can start to collect in the soft tissues. Magnesium citrate is a form of magnesium that provides increased bioavailability.

Vitamin D3: Vitamin D3 is essential for the absorption of calcium and magnesium. Calcium and vitamin D3 work together to promote healthy bones and teeth, as well as provide support for other bodily functions. Vitamin D is essential for bodily system functions such as muscle movement, nerve communication, and hormone secretion.

Vitamin E: This vitamin protects the cells from damage and supports a healthy immune system. To prevent eclampsia, it's often recommended to give an oral calcium supplement to dogs. Oxidative stress could play a part in part if pre-eclampsia, and evidence suggests that vitamin E could reduce the risk of the disorder.

Dextrose: Dextrose raises glucose levels to provide an extra source of quick energy. It is a fast-digesting simple sugar, so it raises blood glucose levels quickly, causing a rapid spike in nutrient-transporting insulin into the bloodstream.

Vitamin B6: This vitamin is necessary for hydrochloric acid production, which is necessary for calcium absorption. It is also needed for the production of hemoglobin and norepinephrine, which helps the body cope with stress.

Coconut Oil: Coconut oil contains antioxidants and medium-chain triglycerides (MCTs) to enhance the absorption of calcium; magnesium, vitamins A, D, E, and K; and amino acids. Coconut oil contains 55% MCTs. 

MCT Oil: MCTs deliver a quick energy source for brain fuel, cognitive support, and mental alertness. They are easy to digest and are absorbed into the bloodstream quickly. They are swiftly metabolized for energy, plus they fuel your body with ketones, which serve as fuel for the central nervous system. Finding the right calcium supplement for your dog is essential for maintaining your furry friend’s overall health!
