About Clinicians Hi-Dose Vit C Sachets

Clinicians Hi-Dose Vit C provides two forms of vitamin C at a mega 3550mg per sachet, for times when high dosing is needed.


What do I use it for?

  • To provide high levels of vitamin C for frequent use to support the body’s defenses with winter ills and chills or when the immune system is challenged.
  • To support adrenal health.
  • High daily level of vitamin C to support well being and for antioxidant protection.


What makes it special?

Two forms of high-level vitamin C per sachet at 3550 mg, buffered so it is well tolerated and easily absorbed by the digestive system. Handy sachets for out and about for daily use or in acute situations when the immune system is challenged.


How does it work?

Hi-Dose Vit C contains two forms of vitamin C, Sodium ascorbate and Ascorbic acid. When ills and chills strike it can be taken every 2-3 hours. Studies show vitamin C absorption is greatly increased when sick before reaching bowel tolerance. This is due to the increased support required for an immune system function. Vitamin C is also important during times of stress as it is required by the adrenal glands to support stress hormones production.



Adults: Mix the contents of 1 sachet in water or juice 1-2 times and stir well. Take 1-2 times daily.
