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.

Product Information

  • The calcium in Ester-C® provides part of your daily calcium requirements
  • Ester-C® contains active vitamin C metabolites including L-threonate, which enhance cellular absorption and retention
  • 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

Works great and so much fun!
Color: Black
How did I live without this for so long? I love this little gadget! It gets used multiple times a day. It's not only great for frothing milk but it will whip eggs for a recipe and stir other ingredients as well. People who have complained that the stirring attachment was missing a piece did not read the description. The picture clearly shows there is no "boot" on that attachment, you don't want that one to spin like the frother. The Frother holds a charge for quite a while as well. I use mine multiple times a day and it is still holding a charge after weeks of daily use. Great item!

The perfect whipper for protein powders
Color: Blue
Love, love this whipper. Had to finally replace my old one that I got several years ago that was battery operated. This rechargeable replacement is incredible. Thought I would miss my old one, but no. The 3 interchangeable attachments make it my go to for a ton of things. Perfect for mixing protein powders!
