Product Information

Bilberry (Vaccinium myrtillus) is the European cousin to the blueberry and contains active ingredients that support vision. It was frequently used by World War II RAF pilots to enhance night vision. 

Studies with bilberry show that it helps eyes adapt to the dark, especially after prolonged exposure to bright light and improves visual acuity in dim light. The active ingredients in bilberry, anthocyanosides, are a group of flavonoids that increase the production and integrity of collagen, a protein that forms connective tissue in the body. Bilberry is also used to treat artery, vein and capillary disorders. Bilberry extract has become the leading herbal prescription for the maintenance of healthy vision and for the treatment of many eye diseases.

Main selling features

  • Standardized extract guarantees 25% anthocyanidins in a base of whole bilberry powder
  • 25% anthocyanidins is the strength used in most clinical studies
  • Safe and high potency herbal extract to support eye health
  • Enhances vascular system health and blood vessel integrity

How it works

The active constituents in bilberry can be traced to a group of flavonoids called anthocyanosides. The anthocyanosides increase the production and integrity of collagen, a protein necessary to connective tissue. Collagen, which is also the most abundant protein in the body, maintains the integrity of tendons, bones, cartilage, and ligaments. Inflammatory diseases such as rheumatoid arthritis and periodontal disease destroy collagen. Bilberry’s anthocyanosides have the remarkable ability to crosslink collagen fibres which reinforces the collagen matrix of connective tissue.

    No problems after a year and a half
    Color: Dogwood & Calming, Size: Medium
    Have been regularly buying these for my corgi for about a year and a half. The 2 pack lasts about a month or 2 each time. Pieces break off in small enough pieces that they safely pass through his digestive system. He gnaws each one down to about 1/4 the original size before we take it away and give him a new one. He continues to have regular bowel movements and has a healthy appetite so I can’t imagine any problems arising after so long. I have tried other alternatives and every other similar chew breaks off in larger pieces and didn’t feel comfortable letting him chew/eat them. I noticed there are a few 1 star reviews saying their dogs got sick off these but after a year and a half I have had 0 issues with this product. I guess it depends on the dog and how big of pieces they are swallowing. My dog ingests pieces about the size of a grain of rice so just pay attention and you should be fine.

    Long lasting and safer alternative to sticks
    Color: Dogwood & Calming, Size: Medium
    These are great, very durable, and have lasted a very long time. Much safer for my dogs than the random sticks they find in the yard. They do get shorter with chewing eventually, but they don't break off in little chunks like I've seen with some nylon chews, and they don't splinter like wood. Medium size works well for both my 16 lb Cavalier and my 60 lb Pyrenees/Golden mix. They're both moderate-to-aggressive chewers, though size obviously affects how much damage they can do. I wish you could buy the hemp chew separately because that one is very much a favorite in my house, so after 2 years and 2 purchases, I have barely any left of the remaining hemp chew, but still 2 of the dogwood chews that neither dog is as interested in anymore. I'd love to buy a couple more of just the hemp one.

    Your dog will thank you.
    Color: Dogwood & Fresh Breath, Size: Large
    My dogs loves to chew on these. They make a small mess but not as bad as other chews. They are food for keeping teeth clean.

    Nice chew toy
    Color: Dogwood Mushroom, Size: Medium, Color: Dogwood Mushroom, Size: Medium
    Super durable and puppy loves it. It was a bit hard for her at first but now at 5 months it’s one of her favorite things to gnaw on! It is heavy for the size but seems to be great quality and has given many hours of chew time with minimal wear.
