SODIUM PANTOTHENATE
Sodium pantothenate (CAS 867-81-2) is a sodium salt form of the biologically active enantiomer of pantothenic acid (vitamin B5), used as a nutrient supplement and precursor to coenzyme A in biological systems.
What It Is
Sodium pantothenate is the sodium salt of the biologically active form of pantothenic acid, also referred to as vitamin B5. As a nutrient supplement, it serves as a source of this essential vitamin, which is required for the synthesis of coenzyme A, a cofactor involved in many cellular processes including energy production and metabolism of fats, carbohydrates, and proteins. The CAS number 867-81-2 uniquely identifies this chemical substance in scientific and regulatory contexts. Pantothenic acid and its salts, like sodium pantothenate, are often included in both food and dietary supplement formulations to ensure adequate intake of vitamin B5. The compound is a white crystalline powder with water solubility that allows it to be incorporated into a wide range of formulations. Because pantothenic acid is widely present in foods, deficiency is rare, but supplemental forms such as the sodium salt are employed to fortify food products. In regulatory inventories, sodium pantothenate appears under nutrient supplement categories and is acknowledged in inventories such as the FDA’s Substances Added to Food list. Its inclusion reflects its recognized use as a nutritional source rather than as a flavoring, preservative, or processing aid, and it is evaluated within the nutrient additives space.
How It Is Made
Sodium pantothenate is synthesized by neutralizing pantothenic acid with a sodium base under controlled conditions to form its monosodium salt. This reaction results in a crystalline powder that is isolated and purified to meet food grade or nutritional supplement specifications. The production process focuses on obtaining high purity material with minimal contaminants, consistent with nutritional use requirements. In industrial practice, pantothenic acid is reacted with sodium hydroxide or a similar sodium source in aqueous solution, after which the resulting sodium pantothenate is crystallized and dried. Quality control during manufacture ensures that the identity, purity, and absence of harmful impurities align with regulatory and safety standards for nutrient supplements. This manufacturing approach avoids introducing extraneous chemical residues and aligns with food-grade ingredient preparation practices. For food and supplement applications, the final product is typically tested for compliance with purity criteria, moisture content, and absence of microbial contamination. These steps help ensure an ingredient that meets consistent functional and safety expectations. Commercial specifications are set based on recognized standards in the industry, though individual producers may have additional quality assurance measures.
Why It Is Used In Food
Sodium pantothenate is used in food primarily as a nutrient supplement to deliver pantothenic acid, an essential vitamin B5. Incorporating this nutrient into food and beverages helps fortify products and supports labeling claims related to vitamin content. Because pantothenic acid plays a role in energy metabolism and overall nutritional balance, manufacturers use its sodium salt to enhance the micronutrient profile of products without altering taste or texture significantly. The functional rationale for using sodium pantothenate in foods includes enhancing nutritional value and meeting regulatory requirements for fortified foods. It is compatible with a variety of food matrices, from dry mixes to liquid beverages, due to its water solubility. As consumers increasingly seek fortified and functional foods, sodium pantothenate provides a reliable source of vitamin B5. Given its recognized safety and nutrient role, sodium pantothenate is often included in fortified grain products, meal replacements, sports nutrition formulas, and dietary supplements to address potential gaps in dietary pantothenic acid intake. Its use reflects both regulatory acceptance in nutrient categories and practical formulation considerations in delivering essential micronutrients.
Adi Example Calculation
An illustrative example helps explain the concept of acceptable daily intake in a nutrient context. Suppose a fortified drink contains a specified amount of sodium pantothenate that provides a small fraction of the daily recommended pantothenic acid intake. If a hypothetical individual with an average body weight consumes multiple servings of fortified products, the total pantothenic acid provided would be compared to established nutrient intake recommendations rather than a safety-derived ADI. For example, if one serving delivers a modest percentage of the daily nutrient reference value for pantothenic acid, multiplying that by several servings provides a total intake that still falls within conventional nutritional ranges. Sodium pantothenate’s role as a vitamin source means that intake assessment is framed around meeting—but not exceeding—nutritional adequacy. This hypothetical scenario illustrates how intake evaluation for nutrient supplements differs from typical toxicological ADI calculations and does not represent individualized guidance.
Safety And Health Research
Sodium pantothenate has been evaluated primarily for safety as a nutrient supplement and is considered safe when used appropriately in food fortification and dietary supplements. Research and regulatory evaluations focus on its role as a source of pantothenic acid, which the body needs for synthesizing coenzyme A, a key cofactor in metabolic processes. Its inclusion in food and supplement products reflects recognition of its essential nutrient status rather than concern over adverse effects at typical intake levels. Regulatory safety assessments consider general toxicology and safety profiles, including potential acute and chronic exposures, though specific ADI values for sodium pantothenate are not broadly reported in JECFA summary databases. In the FDA CFR context, general recognition of safety under good manufacturing practice suggests confidence in its safety when used in standard fortification practices. Its categorization as a nutrient supplement rather than a conventional additive aligns with a body of evidence that supports its essentiality and low toxicity. Scientific literature generally indicates that pantothenic acid and its salts have low toxicity and are well tolerated at nutritional doses. However, the absence of detailed toxicological endpoints in additive-specific authoritative evaluations suggests that its safety research is intertwined with that of pantothenic acid as an essential nutrient.
Regulatory Status Worldwide
In the United States, sodium pantothenate is listed in the FDA’s Code of Federal Regulations (CFR) at section 21 CFR 582.5772 as a substance that is generally recognized as safe when used in accordance with good manufacturing or feeding practices. This regulation indicates that, within the nutrient supplement category, the substance can be used in foods without specific numerical usage limits provided practices align with safety considerations outlined in the CFR. The presence of this regulation demonstrates FDA acknowledgment of sodium pantothenate’s role as a nutrient additive in food formulations. 21 CFR 582.5772 specifies conditions of use and the context of safe incorporation. In the European Union, food additives must be explicitly authorized and assigned an E number before they can be used in food products. As of the available regulatory information, sodium pantothenate does not have a distinct E number listed in the official EU food additives database, and explicit EU use permissions for this compound are not readily found in authoritative sources. The absence of an assigned E number suggests that its regulatory status as a food additive in the EU may differ from other permitted additives. At the international level, sodium pantothenate is evaluated within the context of nutrient sources and listed in global food additive inventories. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) provides specifications and evaluations for many additives, though specific acceptable daily intake (ADI) levels for sodium pantothenate have not been clearly established in publicly accessible JECFA entries. The lack of explicit JECFA ADI details reflects the compound’s classification within nutrient use categories rather than strictly as a conventional food additive.
Taste And Functional Properties
Sodium pantothenate has negligible taste impact at typical use levels in food products, making it suitable for fortification without affecting flavor. The compound is water-soluble, which facilitates its incorporation into aqueous formulations, including beverages and liquid dietary supplements. Its stability in solution and compatibility with other micronutrients support formulation flexibility. From a functional perspective, sodium pantothenate dissolves readily in water and can be blended into dry or liquid product systems. It does not contribute perceptible bitterness or off-notes at the concentrations used for nutritional supplementation. In processing, it remains stable under typical food manufacturing conditions, although extreme heat or prolonged storage under adverse conditions could affect its integrity. The sensory neutrality of sodium pantothenate makes it a practical choice for fortifying foods where maintaining the original taste profile is important. It interacts with standard food ingredients without causing emulsification or textural changes, which is advantageous in formulating complex products like nutritional bars, powdered drink mixes, and ready-to-drink fortified beverages.
Acceptable Daily Intake Explained
The concept of acceptable daily intake (ADI) refers to an estimate of the amount of a substance that can be consumed daily over a lifetime without appreciable health risk. For compounds like sodium pantothenate that serve as nutrient sources, ADI values are not always explicitly defined in the same manner as for conventional food additives such as preservatives or colorants. Regulatory bodies like JECFA and EFSA typically establish ADI values when detailed toxicological data are available and when the compound is used primarily for technological or functional purposes. In the case of sodium pantothenate, its function as a vitamin source means that intake considerations often align with nutritional recommendations rather than safety limits derived from toxicology. Because pantothenic acid is an essential nutrient found in many foods, safety assessments focus on ensuring excess intake does not pose risks rather than imposing strict upper limits. In practical terms, no explicit numerical ADI has been widely published for sodium pantothenate in authoritative additive safety documents. This absence reflects its classification as a nutrient supplement and the understanding that consumption within normal dietary supplementation ranges is unlikely to lead to adverse effects.
Comparison With Similar Additives
Sodium pantothenate can be compared with other vitamin-based nutrient additives such as calcium pantothenate and niacinamide. Calcium pantothenate, another salt form of pantothenic acid, is often used in fortified foods and supplements similarly to the sodium salt. The choice between sodium and calcium salts depends on formulation considerations, such as solubility and product matrix. Both serve as sources of the same essential nutrient. Niacinamide is another B-vitamin derivative used in fortification, providing vitamin B3, and illustrates how different nutrient additives enhance the micronutrient profile of foods without serving traditional additive roles like preservation or coloring. Like sodium pantothenate, niacinamide is generally neutral in taste and compatible with diverse food applications. These comparisons highlight that nutrient supplements such as sodium pantothenate occupy a different functional space than additives used for technological effects, focusing on delivering essential micronutrients rather than modifying sensory or shelf-life attributes.
Common Food Applications Narrative
Sodium pantothenate is frequently used in products where nutritional fortification is a priority, especially those aimed at delivering essential vitamins in convenient forms. Examples include fortified breakfast cereals, where the micronutrient profile is enhanced to meet dietary guidelines or consumer expectations. Similarly, meal replacement and nutrition shake formulations often incorporate sodium pantothenate as part of their vitamin B complex to support overall nutritional balance. In the realm of dietary supplements, sodium pantothenate appears in multivitamin tablets, effervescent powders, and liquid supplement blends designed to provide comprehensive micronutrient support. Its water solubility and functional neutrality allow manufacturers to include it alongside other vitamins and minerals without compromising product aesthetics or taste. Sports nutrition products, such as energy drinks and recovery formulas, also employ sodium pantothenate to ensure that athletes and active individuals receive adequate pantothenic acid as part of broader nutritional strategies. Even in specialized nutrition formulations, such as those for weight management or meal fortification for older adults, sodium pantothenate contributes to delivering essential B vitamins in a form that aligns with consumer expectations for efficacy and convenience.
