What Is Strontium Citrate?

Strontium citrate is a chemical compound that consists of strontium and citric acid. It is derived from the combination of strontium, an alkaline earth metal, with citric acid, a common organic acid in citrus fruits.

Strontium citrate is often used as a dietary supplement due to its potential benefits for bone health. Strontium, as an element, has been studied for its ability to support bone density and reduce the risk of fractures. It is believed to work by promoting the formation of new bone while inhibiting the breakdown of existing bone tissue.

As a supplement, strontium citrate is typically available in powder or capsule form. Strontium citrate should be taken under the supervision of a healthcare expert since it may interact with certain drugs or have special dose requirements.

What Is The Natural Source Of Strontium Citrate Powder?

Strontium citrate is not found naturally in specific food sources. Instead, it is a compound synthesized by combining strontium, an alkaline earth metal, with citric acid, commonly derived from citrus fruits.

Strontium is found in tiny levels in various food and beverage sources. However, the strontium used to produce strontium citrate as a dietary supplement is typically derived from mineral sources, such as strontium carbonate or strontium oxide.

Conversely, citric acid is naturally found in citrus fruits like lemons, oranges, and grapefruits. It can also be produced commercially through fermentation processes using specific strains of mold or bacteria.

By combining strontium and citric acid, strontium citrate is synthesized as a supplement. It allows for a controlled and standardized form of strontium supplementation for potential benefits to bone health.

What Is Strontium Citrate Powder Manufacturing Process?

The manufacturing process of strontium citrate powder typically involves several steps. Here is a general outline of the process.

  1. Sourcing of Raw Materials: The raw materials needed for manufacturing strontium citrate powder, such as strontium compounds and citric acid, are sourced from reputable suppliers.
  2. Strontium Compound Preparation: Strontium compounds, such as strontium carbonate or strontium hydroxide, are prepared or obtained. These compounds serve as the source of strontium for the synthesis of strontium citrate.
  3. Citric Acid Solution Preparation: Citric acid, a common organic acid, is dissolved in water to prepare a citric acid solution. The concentration of the solution is determined based on the desired stoichiometry of the reaction with the strontium compound.
  4. Reaction: The prepared strontium compound and the citric acid solution are mixed together and undergo a reaction. This reaction results in strontium citrate, a salt of strontium and citric acid.
  5. Filtration and Drying: The resulting reaction mixture is filtered to separate any insoluble impurities or byproducts. The filtrate, which contains the strontium citrate solution, is then dried to remove the water and obtain a dry powder. Drying methods such as spray drying, vacuum drying, or freeze drying can be employed depending on the desired characteristics of the final product.
  6. Quality Control and Testing: The obtained strontium citrate powder undergoes quality control tests to ensure its purity, potency, and compliance with safety standards. These tests may include assessing the strontium content, checking for any impurities, and verifying that the product meets the required specifications.
  7. Packaging: Once the strontium citrate powder passes quality control, it is packaged in suitable containers, such as airtight bags or bottles, to protect it from moisture, light, and oxidation. Proper labeling and documentation are typically included as well.

What is Strontium Citrate used for?

Strontium citrate is primarily used as a dietary supplement due to its potential benefits for bone health. Here are some critical uses and potential benefits associated with strontium citrate.

  1. Bone Health Support: Strontium citrate is commonly used as a supplement for bone health. It is believed to promote bone formation and reduce bone resorption, which can help improve bone density and reduce the risk of fractures. It is often used as an alternative or adjunct to other bone-supporting minerals like calcium and vitamin D.
  2. Osteoporosis Management: Osteoporosis is a disorder characterized by decreasing bone density and an increased risk of fractures. Strontium citrate has been studied as a potential treatment option for osteoporosis. It may assist postmenopausal women with osteoporosis in raising bone mineral density and minimizing the risk of vertebral and non-vertebral fractures.
  3. Fracture Prevention: Due to its potential bone-strengthening effects, strontium citrate supplementation may help reduce the risk of fractures in at-risk individuals, such as older adults or those with conditions that weaken the bones.
