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.

Ranitidine outperforms probiotics
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.

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.

Frequently Asked Questions

Diarrhea is a condition characterized by the frequent passage of loose or watery stools, which can occur due to various factors, including infections, dietary choices, and underlying health conditions. It often results from the body's response to an irritation of the gastrointestinal tract, which can be caused by viruses, bacteria, parasites, or certain medications. While most cases tend to be short-lived and resolve on their own, diarrhea can lead to dehydration, especially in vulnerable populations such as young children and the elderly.

Managing diarrhea typically involves staying hydrated by drinking clear fluids and, when necessary, replenishing lost electrolytes. In some cases, over-the-counter medications may provide relief, although it’s essential to consult a healthcare professional for persistent or severe symptoms. A focus on bland, easy-to-digest foods can also help during recovery. Remember, if diarrhea persists for more than a couple of days or is accompanied by other concerning symptoms—like high fever, severe abdominal pain, or blood in stools—seeking medical attention is crucial.

Ascorbic acid, commonly known as vitamin C, is a water-soluble vitamin that is essential for various bodily functions, including the synthesis of collagen, the absorption of iron, and the maintenance of a healthy immune system. Found naturally in a variety of fruits and vegetables, especially citrus fruits, strawberries, kiwi, and bell peppers, it serves as a potent antioxidant, helping to protect cells from damage by free radicals. Given that the human body cannot synthesize ascorbic acid on its own, it must be obtained through diet or supplementation.

In addition to its fundamental role in supporting overall health, ascorbic acid has garnered interest for its potential benefits in skincare and wound healing. Topical applications of vitamin C can help reduce the appearance of fine lines and improve skin texture, making it a popular ingredient in various cosmetic formulations. Additionally, it plays a crucial role in the body's ability to repair tissues and produce important neurotransmitters. For those looking to boost their vitamin C intake, incorporating a variety of vitamin C-rich foods into your diet or considering a supplement can be effective strategies.

User reviews indicate a variety of experiences regarding the time it takes to see results when using this supplement for diarrhea. Some users have reported immediate relief after finding their optimal dosage, stating it effectively relieved diarrhea quickly, often within a day of adjusting their intake (see review id='1438a216-aaa9-454c-bdb0-3c6f1f488831'). However, others mentioned experiencing issues related to dosage and timing, which could lead to a delay in finding relief. For instance, one user noted that they faced diarrhea when not realizing the accumulation of the supplement was causing issues, suggesting that correct timing is vital for effective results (see review id='68e72671-2968-4e8f-9fc3-28da03eae79c'). Overall, the time frame for noticeable results seems to depend on individual responses to the supplement and correct dosage administration.

Based on the available research, there is evidence supporting the use of Vitamin C in managing diarrhea, particularly in calves. A study involving Holstein calves demonstrated that those supplemented with Vitamin C experienced improved health outcomes during diarrhea episodes, including increased weight gain and fewer days of required medication for treatment compared to those without the supplement [1]. This suggests that Vitamin C could play a beneficial role in promoting recovery and overall health during episodes of diarrhea in young calves.

When it comes to human subjects, a study examined the effects of probiotics combined with Vitamin C on toddler's diarrhea. Although the results indicated that oral ranitidine was more effective than the probiotics in reducing stool frequency and improving consistency, the role of Vitamin C was not clearly defined due to its combination with probiotics [2]. This uncertainty highlights the need for further studies to isolate the effects of Vitamin C on diarrhea in humans. Overall, while there is some research supporting Vitamin C's beneficial effects in calf diarrhea management, its efficacy in human diarrhea remains inconclusive and warrants additional investigation.

User reviews reflect a mixed bag of experiences when it comes to symptom improvements, particularly relating to digestive comfort. Some users report that the sustained-release formulation works effectively without causing any gastrointestinal distress. For instance, one individual noted that they didn’t experience any stomach aches or diarrhea after adjusting their dosage, ultimately finding relief while adhering to a regimen of one tablet per hour (see review id='599e267b-ca2c-4473-96d0-0fc9ed23c3d9'). Similarly, another user praised the product for not causing stomach cramps or diarrhea, underscoring its suitability for their daily routine (see review id='3e19d425-2408-4656-90f9-788f6523b49d').

Conversely, some users expressed that they faced significant digestive discomfort or diarrhea, particularly when mismanaging their dosage. One user reported recurrent stomach irritation and diarrhea, leading them to abandon the product entirely after multiple attempts (see review id='6ba01a54-3d23-447f-845f-252fcbe09e70'). Another noted that they had diarrhea upon inadvertently taking too many tablets without realizing how the supplement accumulates in the body (see review id='68e72671-2968-4e8f-9fc3-28da03eae79c'). In essence, while many users experienced positive outcomes, results can vary considerably based on individual tolerance and dosage management.

Users report varied experiences when it comes to combining this vitamin C supplement with other products for managing diarrhea. Some individuals found that taking the supplement without other complementary supplements led to positive results, effectively managing their diarrhea while minimizing any associated gastrointestinal discomfort. For instance, one user highlighted that after adjusting their dosage, they experienced no stomach aches or diarrhea, indicating the importance of dosage management (see review id='599e267b-ca2c-4473-96d0-0fc9ed23c3d9'). Conversely, others experienced significant gastrointestinal issues, including diarrhea, often due to improper dosage or sensitivity to the supplement itself. One user noted recurrent stomach pain and diarrhea when they didn't gauge their intake appropriately, leading them to stop using it altogether (see review id='6ba01a54-3d23-447f-845f-252fcbe09e70').

Additionally, some users reported experiences of discomfort and diarrhea when combining this supplement with other forms of vitamin C or while on specific dietary guidelines. For example, one user mentioned suffering from diarrhea while not recognizing the cumulative effect of taking the supplement too frequently (see review id='68e72671-2968-4e8f-9fc3-28da03eae79c'). This suggests that while some users may find a successful routine with this supplement, others with sensitive stomachs or poor dosage management may face challenges, particularly when combining it with other supplements.

Based on user reviews, finding the right dose of Vitamin C for treating diarrhea varies significantly among individuals. Some users reported that taking one tablet at an hourly rate (1000 mg sustained-release) effectively relieved their symptoms without causing any stomach discomfort or diarrhea (Read Review). However, others experienced adverse effects, with reports of stomach pain and diarrhea when taking similar doses (Read Review).

It seems that sensitivity to Vitamin C plays a crucial role in determining the right dose. For instance, one user stated that they initially took too high of a dose, leading to diarrhea, but once they found their appropriate dose, their experience improved significantly (Read Review). Additionally, another user noted that taking one tablet after meals resulted in diarrhea due to accumulation, suggesting that spreading the doses throughout the day might be more effective for some (Read Review). Overall, it appears that users recommend adjusting the dose according to individual tolerance.
