Helps to support a healthy immune system.

Vitamin C is a water-soluble antioxidant and one of the best researched nutrients. Most mammals can produce vitamin C as they need it but the human system evolved without this ability, therefore we must ensure an adequate daily intake to stay healthy. Vitamin C is found in fruits and vegetables, but it is easily destroyed by heat, cooking, processing, and storage and rapidly eliminated from our system in the urine. Inadequate levels of vitamin C may be seen in cases of physical and mental stress, older people, and those with chronic conditions including cardiovascular disease, asthma, arthritis, age-related eye disease, and certain cancers. Vitamin C is best known for strengthening the immune system by supporting and improving white blood cell function. It is also essential for the proper formation of collagen, the building block of many tissues and a crucial component in skin rejuvenation. Vitamin C also helps to reduce histamine release in the body, thereby alleviating allergy symptoms. There are numerous forms of vitamin C with ascorbic acid being the most basic. People wanting a clinically proven form that is easier on the system than ascorbic acid should choose a form like Ester-C® brand calcium ascorbate.

  • Ester-C® is the only form of vitamin C that has been proven to last up to 24 hours in the white blood cells of the immune system
  • Less acidic and easier on the stomach than ascorbic acid
  • Enhanced with quercetin, a bioflavonoid and powerful antioxidant with anti-inflammatory and antihistamine properties
  • Added bioflavonoids from berry fruits for superior vitamin C absorption

Better than beds I've spent double the money on!
Size: 20.0"L x 20.0"W x 6.0''TH, Style: Round, Pattern Name: Bed
This bed is actually amazing for the price. My chihuahua digs a hole through every bed he's ever had except this one. The bottom actually went flat before he was able to dig a hole into the fabric. But since its such a great bed, i cut open the bottom and restuffed it from the filling from an old pillow and stitched it back up so he can keep enjoying it. Abd if he eventually does dig a hole in it, ill be rebuying this same bed.

My cat used it right away!
Size: 20.0"L x 20.0"W x 6.0''TH, Style: Round, Pattern Name: Bed
My large long-hair orange cat is a bed hoarder. He has at least 5 or 6 beds around the house, and uses every one of them (at different times, of course). But lately he's started sleeping on my pillow during the day, but going to bed at night on a pillow covered in his long orange hair wasn't cutting it for me. So I purchased one more bed for him - because heaven help me if I should move one of his other beds. What we won't do for our babies! Anyway, I put this new bed near my pillow and he's been using the bed instead of my pillow. It's soft and the bolsters are thick and it's just the right size for him to curl up in! He loves it! Win-win!

Lopsided, but works
Size: 20.0"L x 20.0"W x 6.0''TH, Style: Round, Pattern Name: Bed
It's soft and good cat size. The bottom stuffing is uneven, so it leans a lot, no matter how I rotate it for the cat to try to even it out. But the old cat loves it, especially since it's positioned in a perfect spot; a "corner" by a hallway, so it feels safe, while letting the cat see everything from that out of the way vantage point. I've been trying to get him to use beds again (had to throw some out b/c he gets seizures which can result in loss of bladder control). It only took a few days for him to "discover" the new bed, and start adding it to his nap rotations. and he looks so cute in it.
