Sisu Cold & Flu Rescue With Ester-C - 60 V-Caps

Vitamin C: How it Helps

Most people consume Vitamin C in the form of ascorbic acid, but ascorbic acid passes out of the body quickly, so little of it is absorbed. It can also cause gassiness, bloating, and diarrhea. Ester-C is made from calcium ascorbate formulated through a patented process so that it neutralizes intestinal acids and can therefore be absorbed without discomfort. It also contains a form of calcium, which enhances absorption.

The familiar symptoms of head and body aches, sinus and chest congestion, coughing and sneezing are all indications that a cold or flu virus has significantly multiplied and your body is working to expel it and destroy affected cells. Over-the-counter drugs are effective at suppressing only some of the symptoms, and often have negative side effects. A better option is to choose natural health products that stimulate the immune system to kill the virus before full-blown symptoms develop.

Cold & Flu Rescue is a unique combination of four powerful ingredients, Ester-C, andrographis, NAC, and echinacea, each of them proven in human research to lessen the severity and duration of cold and flu symptoms.

NAC (N-acetyl-L-cysteine) protects lungs against respiratory infection and reduces phlegm and symptoms of chronic bronchitis.

Andrographis is an anti-inflammatory herb that stimulates the immune system and helps against cold and flu symptoms including sore throat. High-potency echinacea extract is a powerful immune stimulant and is most effective when taken at the onset of infection

Vitamin C

Vitamin C is the most widely used supplement. Humans cannot manufacture their own vitamin C; therefore it must be taken in through the diet. Vitamin C is a water-soluble antioxidant that is used all over the body. It speeds tissue growth and repair, supports hormone production, increases immune system functioning, protects the body from toxins and supports healthy cell growths. It also regulates cholesterol, blood pressure and blood clotting.
There are several types of vitamin C. Ascorbic acid is the basic form. To buffer the natural acidity of vitamin C manufacturers can bind it to other molecules. Two examples are calcium ascorbate (Ester-C) and ascorbyl palmitate. It also makes vitamin C easier for the body to absorb and decreases the loss of the vitamin through the urine. This increases the cost of the supplement but it is beneficial to those taking high doses of vitamin C and those who cannot tolerate acidic substances.

Vitamin C comes in a variety of dosage forms including conventional pills, time-released tablets, syrups, powders and chewable tablets. A qualified practitioner can even administer it intravenously. Vitamin C is usually derived from corn or dextrose but tapioca-sourced C is also available. Vitamin C is often combined with bioflavinoids like hesperidin and rutin. These substances work synergistically with Vitamin C. Rose hips are a good substitute for straight vitamin C because they are the richest natural source of vitamin C. Rose hips are also a good source of bioflavinoids. Vitamin C is lost in the urine only a few hours after it is taken so frequent dosing is important.
