Seaweed Calcium for dogs and cats is a natural source of highly bioavailable calcium. This is a wonderful product for all the home-preparers out there and a great alternative to less bioavailable sources of calcium like bone meal, inorganic calcium carbonate or egg shells. Other calcium sources, like bone meal, can also have a higher lead content in addition to being less nutritious.

An animal's digestive system is not designed to obtain its dietary calcium requirements from rock. This type of calcium, unfortunately used in the majority of calcium supplements offered to consumers, is poorly absorbed. In addition, magnesium is needed to move the calcium into the bone. Without magnesium the calcium will accumulate on blood vessel walls leading to a condition known as atherosclerosis (hardening of the arteries). Numerous studies have shown that this condition is not as likely to occur with plant-based calcium sources that contain a variety of minerals and in fact it has been shown that bone mineralization is far superior when supplementing with a plant-based calcium source.

Available in a 6 ounce container.

Is Common, Inorganic Mineral Calcium Carbonate a Good Calcium Source for My Dog or Cat?

Calcium carbonate provides 40 percent elemental calcium; the other 60 percent is the carbonate ingredient. During digestion, the elemental calcium is released from the compound and becomes available for absorption. So, for example 1000 milligrams (mg) of calcium carbonate provides only 400 mg elemental calcium. But that isn't all, you have to consider bioavailability. Inorganic calcium carbonate has a bioavailability of only approximately 15%, making it, in our opinion, a poor source of calcium for your dog or cat.

What to Look for in a Superior Calcium Supplement for Dogs and Cats...

Plant-Based Calcium

Plant-based calcium is a safe and highly bioavailable source of calcium rich in magnesium and over 70 other trace minerals known to play a role in bone health. Studies suggest that the unique mineral composition of red algae not only promotes bone formation, making it useful in treating bone diseases such as osteoporosis, but also has potent anti-inflammatory potential.

Natural Ingredients

Natural ingredients are going to be gentler on your animal's body when compared to synthetic chemical ingredients or medications. Natural ingredients are also better absorbed with exceses more easily eliminated without causing toxicity.

No Unhealthy Additives

Our calcium is made with all-natural, whole food ingredients. Absent are the fillers that increase packaging bulk and "flow agents" that make manufacturing faster and easier. Ingredients we avoid, but many of our competitors do not, include lactose, magnesium stearate, maltodextrin, stearic acid, calcium stearate, scorbyl palmitate, silicon dioxide, and microcrystalline cellulose among others.

Uses only Human Grade Ingredients

Our products are manufactured using human grade ingredients. In the pet industry this is far from the rule as many companies use pet quality ingredients, those considered "not fit for human consumption".

Uses Fresh, High Quality Ingredients

We purchase our ingredients from some of the most highly regarded companies in their respective fields so you and your animals are ensured the finest quality supplements. In addition, we purchase in small quantities to make sure the products we provide to you are fresh and bursting with important nutrients. This is in direct contrast to many other products on the market that can spend a year or longer sitting in non-climate controlled warehouses before they even get to you.

After switching to this calcium supplement for my two dogs, I have noticed a real change in their activity levels and the shine of their coats. Other family members have noticed the difference also and made comments. I had no idea that the source of calcium could make such a big difference. I'm so glad that I found this company while my dogs are still young before I damaged their health.
