HOW IT WORKS

Vitamin D comes in two forms: D2 and D3.
Of the two, D3 is more bioactive. The body synthesizes vitamin D3 from cholesterol and sunlight; which makes it difficult to obtain adequate amounts of vitamin D during cloudy or winter months. In the body, vitamin D is responsible for maintaining normal blood levels of calcium and phosphorus, and helping to build strong bones.
It works with other vitamins, minerals and hormones to promote bone mineralization. Research shows that vitamin D may help support a healthy immune system by regulating lymphocyte function, cytokine production and macrophage activity.
Studies also show that Vitamin D may improve mood.

WHY VITAMIN D3

Vitamin D3 offers a host of health benefits.
It supports both the innate and adaptive branches of the immune system. 
It influences mood, and, along with calcium and other minerals, it supports bone health. 
On top of all these gains, Nature’s Sunshine’s Vitamin D3 partner supplies us with a super-clean nutrient; one that is proudly allergen-free and non-GMO project verified.

THE STORY BEHIND VITAMIN D3

Vitamin D was discovered as researchers worked to end rickets, a bone disease in children, in the early 20th century. Sir Edward Mellanby discovered that cod liver oil—a source of vitamin A—could alleviate symptoms of rickets. Later, Professor Elmer McCollum tested cod liver oil without vitamin A.
When it still prevented rickets, he assumed that a yet-undiscovered nutrient was responsible. He named this nutrient vitamin D.
In 1937, vitamin D3 was identified by former Nobel-prize-winner Adolph Windaus and his associate. They found that vitamin D3 formed in the skin after it was exposed to sunlight.
In 1952, a team of researchers discovered that vitamin D did not actually put minerals into the bone, but rather mobilized calcium from the bone into the plasma. This led to the understanding of vitamin D’s role in maintaining serum calcium, which affects both skeletal strength and neuromuscular function.

Great product! Durable, chewable, awesomeness!
Color: Grilled color, Color: Grilled color
Very well made and durable. My dog hasn't left them alone since i opened them. Hes been at it for about 45 minutes straight now! Lol. He's an avid chewer. He will chew thru and fabric or cloth toys in less then a day. But these are what he really likes because they take time to chew apart. The shapes, are great, because one he props up with his paws and chews and it seems like it's easy to grip for him. Thru are hard so if you have hard floors it can get a bit noisy when he drops them. Over all this is a great product. Safe, chewable, long lasting, fun shape looks real to him (i think lol), Me and my dog Lucky are both happy with his new toys!

Amazingly great product!
Color: Grilled color
I’m not just saying this, ok, this is not hyperbole: this is THE best nylon bone for chewing that I have ever purchased. And you get TWO of them for relatively less expensive than most chew toys give you one! I have 2 golden retrievers, and if you know goldens, you know that they are some of the most relentless and powerful chewers around. So I can’t give them almost any toy other than rubber stuff or it will be destroyed in a period of time that doesn’t make it worth it. One of them even figured out how to destroy a supposedly indestructible toy made out of kevlar! She was able to get into it through the seam, which is not kevlar ha ha. Anyway, I digress; I never even considered nylon chews because they suck! Usually. Usually my dogs in the past have lost interest with them in less than a day. I took a chance on these mainly because of the novel shapes, the fact that they give you two, and the low price. Both my goldens LOVE these! Not just for one day, but going on weeks now! I don’t know if it’s the flavor or what, but I will see them gnawing on one of them at some point every day. And they CAN’T destroy them (I knew nylon was good for that, but it was the “who cares” attitude of my previous dogs toward nylon that kept me away). Both the “ribs” and “steak” (quite clever) are a bit worn on the edges now, but they look like they will be around for years. You can’t go wrong with this product (unless for some reason your dog does not like the flavor, but the flavor seems to be what draws my dogs to them). I highly recommend this (these) as the most cost-effective chew toy I’ve ever purchased.

Great for larger dogs
Color: Grilled color
I think they were heavy duty and durable, but they were too heavy for my dog. The seller was excellent though!
