The human body does not efficiently absorb very high doses of vitamin C; absorption rates significantly decrease at intakes exceeding 1000mg. When considering supplementation, a common question arises: is it better to take 500mg or 1000mg of vitamin C?

According to the World Health Organization, the International Unit (IU) was first defined in the 1930s to standardize the biological activity of vitamins and other substances. This makes understanding the difference between mcg and IU a long-standing challenge for consumers reading supplement labels.

According to the National Health Service (NHS), one milligram (mg) contains 1,000 micrograms (mcg), making the answer to 'Is 5mg equal to 400 mcg?' a definitive and medically significant 'no'. This is a critical point of distinction when managing medication and nutritional supplements, where accuracy is paramount to health and safety.

According to scientific studies, the effectiveness of oral glutathione is significantly impacted by poor absorption, which makes understanding dosage a critical factor for achieving desired results. Deciding if 250 glutathione is better than 500 is not a simple choice, but depends on your specific health objectives, the supplement's form, and duration of use.
