We investigated how adding vitamin C to milk influences the growth and health of young calves, particularly those experiencing diarrhea. The study involved 48 Holstein calves, which were sorted into two groups based on their health status: healthy calves and those with diarrhea. Each calf was fed the same amount of pasteurized milk and monitored until they reached 74 days of age.
Calves that received vitamin C showed an impressive increase in weight by weaning—74.3 kg compared to 72.2 kg for those without vitamin C. Additionally, calves treated with vitamin C demonstrated improved blood antioxidant levels, suggesting better overall health. Notably, calves suffering from diarrhea benefitted significantly from the vitamin C, needing fewer days of medication for treatment compared to those who did not receive the supplement.
The research highlights that vitamin C can play a critical role in supporting the health of calves during episodes of diarrhea. This is especially relevant for those that faced even mild cases early in life, as they seemed to gain the most benefits from the supplementation. Overall, it appears that vitamin C can positively impact both growth and health in calves suffering from diarrhea.

We explored the effectiveness of a short course of oral ranitidine compared to probiotics in treating toddler's diarrhea. In a carefully designed trial, 40 participants were randomly assigned to three groups: those receiving ranitidine, those taking probiotics with vitamin C, and a placebo group.
Our main focus was to see if any of these options could reduce the frequency of stools and improve their consistency after ten days of treatment. While the results showed that oral ranitidine outperformed probiotics in managing toddler's diarrhea, the role of vitamin C was less clear.
It's important to highlight that in this study, the probiotics were combined with vitamin C, making it difficult to isolate its individual effects on diarrhea. Overall, we found that ranitidine was more effective than the probiotics, but we can't confidently say how vitamin C contributed to the outcomes. We recommend further studies to investigate these treatments in more detail.

Indispensable supplement

Must! I've been drinking this for over six years now. I generally take one tablet every three hours as a guideline. If I feel unwell, I continue to take one every 30 minutes until just before experiencing diarrhoea. Thanks to you, I don't know the hospital. It's an absolutely indispensable supplement for managing my physical condition.

Gentle on stomach
A very good product that's not too aggressive on my stomach and intestines. Other vitamin C products cause me diarrhoea, but this one is fine! The price is very good. I love Now Foods.

Excellent! I highly recommend it because I haven't experienced any diarrhoea despite taking a significant amount.

Improved overall health
This Vitamin C-1000 is my go-to. There's a lower dosage, yet it's clear my body and family need this higher dosage because exceeding our capacity causes diarrhoea, but we don't experience those issues anymore. Since we've started taking it, our skin, allergies, and overall health have markedly improved.

Monitor vitamin intake
The tablet is a bit large, but you can cut it in half. This is likely because the dosage is high at 1000 mg. We take one pill a day, and if we're unwell or have inflammation, we may take 2-4 pills daily. Excess vitamin C is excreted through the digestive system (when experiencing diarrhoea, stop taking vitamin C as you've had enough). When there’s a fever, take vitamin C straight until diarrhoea occurs. If breastfeeding, vitamin C will pass to the baby via breast milk.
