Vitamin C als Natriumascorbat
Also known as: Sodium ascorbate, Vitamin C sodium salt, Natriumascorbat, Sodium Ascorbate
Overview
Sodium ascorbate is a water-soluble, less acidic form of vitamin C, also known as ascorbic acid. It is created by combining ascorbic acid with sodium, making it gentler on the stomach compared to pure ascorbic acid. Vitamin C is an essential nutrient found naturally in various fruits and vegetables, playing a crucial role in immune support, collagen synthesis, and acting as a potent antioxidant. Sodium ascorbate is often preferred in food and pharmaceutical applications due to its enhanced stability and solubility in aqueous solutions. While extensive research supports the benefits of vitamin C, specific studies focusing solely on sodium ascorbate are less common, necessitating extrapolation from broader vitamin C research. It is generally well-tolerated and considered safe when taken within recommended dosage ranges, making it a popular choice for individuals seeking the benefits of vitamin C without the potential gastrointestinal discomfort associated with more acidic forms.
Benefits
Vitamin C, including sodium ascorbate, has been shown to reduce blood pressure. A meta-analysis indicated a reduction of approximately -3.84 mm Hg in systolic blood pressure and -1.48 mm Hg in diastolic blood pressure with vitamin C supplementation. It also supports immune function by enhancing the activity of immune cells and reducing oxidative stress through its antioxidant properties. Critically ill patients may experience reduced duration of vasopressor use and mechanical ventilation with vitamin C supplementation, as shown in a meta-analysis. These benefits are typically observed within weeks of consistent supplementation. The effect sizes for blood pressure reduction are moderate and clinically significant, highlighting the potential cardiovascular benefits.
How it works
Sodium ascorbate functions primarily as an antioxidant, neutralizing free radicals and protecting cells from oxidative damage. It supports collagen synthesis by hydroxylating proline and lysine residues, which are essential for the structural integrity of collagen. Vitamin C enhances immune function by supporting the activity and proliferation of immune cells. It interacts with the cardiovascular system by improving endothelial function and reducing blood pressure. Sodium ascorbate is highly soluble and bioavailable when ingested orally, facilitating its absorption and utilization within the body.
Side effects
Sodium ascorbate is generally considered safe when consumed within recommended limits. Common side effects, occurring in more than 5% of users, include gastrointestinal upset and diarrhea. Uncommon side effects, affecting 1-5% of individuals, may include the formation of kidney stones in susceptible individuals. Rare side effects, occurring in less than 1% of users, include allergic reactions. High doses should be avoided in individuals with pre-existing kidney issues due to the increased risk of kidney stone formation. Sodium ascorbate may interact with certain medications, such as blood thinners, potentially affecting their efficacy. Pregnant women and individuals with kidney disease should consult healthcare providers before taking high doses of sodium ascorbate.
Dosage
The minimum effective dose of sodium ascorbate for general health is typically around 60 mg per day. Optimal dosage ranges for specific health benefits, such as immune support and antioxidant effects, are between 500 mg to 2,000 mg per day. The maximum safe dose is generally considered to be 2,000 mg per day, although higher doses may cause gastrointestinal side effects. It is best taken with meals to enhance absorption and reduce the risk of gastrointestinal discomfort. Sodium ascorbate is suitable for individuals who prefer a less acidic form of vitamin C. Bioavailability is high when taken orally. No specific cofactors are required for its absorption or utilization.
FAQs
Is sodium ascorbate better than ascorbic acid?
Sodium ascorbate is less acidic than ascorbic acid, making it suitable for individuals with sensitive stomachs. Both forms provide vitamin C, but sodium ascorbate may cause less gastrointestinal upset.
Can high doses of sodium ascorbate cause kidney stones?
High doses of sodium ascorbate may increase the risk of kidney stone formation in susceptible individuals. Individuals with kidney issues should consult a healthcare provider before taking high doses.
When is the best time to take sodium ascorbate?
It is best taken with meals to enhance absorption and reduce the risk of gastrointestinal side effects. Consistent daily intake is more important than the specific time of day.
Does vitamin C cure colds?
Vitamin C does not cure colds, but it may reduce their duration and severity by supporting immune function. Regular intake may help in preventing frequent colds.
What are the expected benefits of taking sodium ascorbate?
Benefits may include improved immune function, reduced blood pressure, and antioxidant protection. Individual results may vary based on overall health and dosage.
