What are ascorbic acid tablets used for, and how do they benefit the body? - #14729
I recently started taking ascorbic acid tablets, but I’m not sure exactly how they benefit my health. I know it’s a form of vitamin C, but I don’t fully understand why I need it or how it works. What exactly is ascorbic acid, and how does it support the body’s functions? I know it helps boost the immune system, but does it also have other roles, like promoting skin health or improving iron absorption? Also, how much ascorbic acid do I need each day, and can it be harmful in excess? I also want to understand if there are natural sources of ascorbic acid that work just as well as tablets. Does eating fruits like oranges and berries give me the same benefits, or are supplements necessary for higher doses? If anyone has used ascorbic acid tablets, what health issues did they help with, and did you experience any side effects or benefits?

Doctors’ responses
Ascorbic acid, or vitamin C, is an essential nutrient that supports several key functions in the body. It boosts the immune system, promotes healthy skin by aiding collagen production, and enhances iron absorption from plant-based foods. Vitamin C also acts as a powerful antioxidant, helping to protect cells from damage. The recommended daily intake of vitamin C varies by age and gender, but for most adults, it’s about 65-90 mg. Excessive intake, particularly above 2000 mg per day, can lead to side effects like stomach upset or kidney stones. While supplements like ascorbic acid can provide a concentrated dose, natural sources such as citrus fruits, strawberries, bell peppers, and leafy greens offer plenty of vitamin C and may be just as effective. A balanced diet usually provides enough, but supplements can be helpful for higher doses or specific health needs.
Ascorbic acid is simply another name for vitamin C, an essential nutrient that supports various body functions. You’re absolutely right thinking it boosts your immune system; it plays a big role in that. Besides, it’s also great for your skin because it helps produce collagen, the protein that keeps your skin firm and helps with healing wounds.
You’re spot on about iron absorption too. Vitamin C improves the absorption of non-heme iron, the type found in plant-based foods which is typically harder for the body to absorb. A good tactic is to pair vitamin C-rich foods with iron-rich meals to enhance this effect.
Now, how much do you need? Well, the recommended daily amount for adults is around 65 to 90 milligrams, but larger doses, like 500 mg or more, are often used therapeutically. But be careful with really high doses, like above 2000 mg per day, as they could lead to side effects like stomach upset or even kidney stones.
Regarding natural sources, consuming fruits and vegetables is actually a fantastic way to get enough vitamin C. Fruits like oranges, strawberries, kiwi, as well as veggies like bell peppers and broccoli, are excellent sources. If your diet includes a variety of these, you might not even need supplements. However, if you’re dealing with specific health issues or dietary restrictions, supplements can help, but they really should be used to complement a balanced diet, not replace it.
Some folks use vitamin C for skin health, reducing fatigue, or when fighting off a cold. It’s generally well-tolerated, but as I mentioned earlier, taking too much isn’t a wise idea. It’s like, more isn’t necessarily better, you know? Keep it balanced, and talk to a healthcare provider if you’re thinking about making any big adjustments, especially if they might interact with other meds you’re on. Stay mindful and take care!
