B vitamins are a group of water-soluble vitamins that help enzymes react chemically with other substances and are involved in energy production and red blood cell formation. The B vitamins help the body metabolize carbohydrates, proteins, and fats. They also help with normal growth and development, and in tissue formation.

In times of physical and mental stress, the body uses up more nutrients, leading to deficiency and stress-related health problems. Nutritional support is needed for periods of stress, when the body isn’t able to adequately recover without the proper nutrients.

Natural Factors Stress B Formula contains a unique blend of B vitamins to help combat the negative effects of stress. Additional lipotrophic factors choline and inositol help the body metabolize foods and convert them to energy. This formula also contains 1000 mg of vitamin C for extra support, immune function enhancement, and antioxidant support.

Vitamin C is a powerful vitamin with infection-fighting properties, playing a large role in immune system function. Vitamin C is crucial for the formation of collagen, making this vitamin very important for wound repair, healthy gums, strong bones and teeth, and in the prevention of bruising.

 

  • High levels of folic acid (1000 mcg) 
  • Plus 1000 mg of vitamin C 
  • With additional lipotrophic factors choline and inositol to support metabolism and energy

All 3 dogs, 3 different sizes and ages love it! Can’t go wrong!
Size: Medium, Style: Bristle Bone
Great! Super great! When you HAVE TO GET THEM OUT OF YOUR HAIR! This toy is durable even without the beef flavored insert! I have a Border Collie who has too much energy and an Aussie who can’t sit still and a small stray who is constantly figuring out a way to steal these from the other two! Safe, effective and actually cleans their teeth! This might well be my first Amazon review because this toy deserves it!

Bully approved
If he wants something to gnaw on he will sit with it but he doesn't really play with it. Which is probably the point. It's lasted. The ends are the most chewed. Overall great for a chewer!

Surprisingly Durable
Color: Green
Our dog is an aggressive chewer. She has destroyed other toys meant for "aggressive chewers" in less that 6 hours. This toy has lasted 17 days and it's still going. It does have areas were the seam has given way and a very small amount of stuffing has come out. She has "killed" the squeaker. But the toy is still usable. We just played Tug of War this morning. It will not last forever. It is showing it's "age". But the durability is there. I am ordering more.

Durability and lasting period of toy.
Color: Green
I got this toy for our bulldog. He had a hole in it, which will only progress, within minutes. I took it away until I could find out if there is any kind of warranty. The information says this toy is not for aggressive chewers, yet right in the description and the photo of the toy (that way I knew I was looking at the correct toy), it says for the "aggressive chewer". I am disappointed that even though it isn't how they described, it only lasted minutes before there was damage. Not sure if I would buy another product.
