Quattroceutical Ltd. recently conducted a survey of 1021 individuals, shedding light on prevalent vitamin consumption trends. Vitamin C and D emerged as the most commonly taken supplements, with a striking 40% of respondents consuming 1000 mg of vitamin C daily—far exceeding the recommended daily intake of 80 mg.
Nikoletta Molnár, Head of Research and Development at Proformance Lab, emphasized the variability in individual vitamin needs and the potential influence of seasonal changes on these requirements.
While 1000 mg of vitamin C might be excessive for many, personal variations and seasonal demands could alter these needs. Vitamin C, being water-soluble, is typically eliminated within 4-6 hours through urine. However, taking large doses at once may reduce absorption rates, leading to excretion levels of about 50-60% at 1000 mg.
Contrary to the belief that excess vitamin intake is harmless due to the body’s excretion process, it can actually strain the kidneys and potentially contribute to kidney stone formation. Moreover, considering the combined intake from dietary sources like fruits, vegetables, and supplemental forms, an additional 1000 mg of vitamin C could significantly burden the kidneys.
In essence, while vitamin C is crucial for health, excessive intake beyond recommended levels can pose risks, particularly regarding kidney health. Adhering to recommended daily values and recognizing individual differences in vitamin requirements is crucial when considering vitamin supplementation.
