About Clinicians Hi-Dose Vit C

Studies indicate that frequent high dosing with vitamin C can significantly shorten the recovery time when the body's defenses are under attack. This appears to be true for both oral and intravenous vitamin C administration.  In addition to supporting recovery, these high-dosing regimes may also support quicker recovery times.

In order to get the full benefit of this regime, you should dose to bowel tolerance. Bowel tolerance is reached when the following symptoms occur; bowel discomfort, distention, diarrhoea and flatulence. Individual requirements for vitamin C may vary depending on severity of illness and levels of stress and higher dosing may be required during these times.

Once bowel tolerance is achieved, you should continue on the maintenance dose recommended for this product,

You may also benefit from taking the following Clinicians products alongside Hi-Dose Vit C : Stress & Energy Support (to address fatigue & lethargy), VirActive Seasonal, Vitamin B12 Oral Drops and Del- Immune V® (for additional immune support),LipGuard (for lip health in times if immune stress), MultiVitamin and Mineral Boost for added mineral and nutrient support.
