  • Lowering cholesterol.

  • Lowering blood pressure.

  • Decreasing the amount of the certain heavy chemicals taken up (absorption) by the body. These chemicals include strontium, barium, tin, cadmium, manganese, and zinc.

  • Other conditions.

More evidence is needed to rate the effectiveness of algin for these uses.

See Slideshow Special Precautions & Warnings Pregnancy and breast-feeding: Dried algin is LIKELY UNSAFE when inserted into the cervix to induce labor, as it has been linked with serious adverse effects. Not enough is known about the use of algin during pregnancy when taken by mouth or when used in any form during breast-feeding. Stay on the safe side and avoid use.

Algin is a thick gel. Algin can stick to medications in the stomach and intestines. Taking algin at the same time as medications that you take by mouth can decrease how much medication your body absorbs, and decrease the effectiveness of your medication. To prevent this interaction, take algin at least one hour after medications you take by mouth.

The appropriate dose of algin depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for algin. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.

Alginic acid, also called algin, is a naturally occurring, edible polysaccharide found in brown algae. It is hydrophilic and forms a viscous gum when hydrated. With metals such as sodium and calcium, its salts are known as alginates. Its colour ranges from white to yellowish-brown. It is sold in filamentous, granular, or powdered forms.

Alginates are refined from brown seaweeds. Throughout the world, many of the Phaeophyceae class brown seaweeds are harvested to be processed and converted into sodium alginate. Sodium alginate is used in many industries including food, animal food, fertilisers, textile printing, and pharmaceuticals. Dental impression material uses alginate as its means of gelling. Food grade alginate is an approved ingredient in processed and manufactured foods.[4]

Alginates from different species of brown seaweed vary in their chemical structure resulting in different physical properties of alginates. Some species yield an alginate that gives a strong gel, another a weaker gel, some may produce a cream or white alginate, while others are difficult to gel and are best used for technical applications where color does not matter.[5]

Commercial grade alginate are extracted from giant kelp Macrocystis pyrifera, Ascophyllum nodosum, and types of Laminaria. Alginates are also produced by two bacterial genera Pseudomonas and Azotobacter, which played a major role in the unravelling of its biosynthesis pathway. Bacterial alginates are useful for the production of micro- or nanostructures suitable for medical applications.[6]

Alginate absorbs water quickly, which makes it useful as an additive in dehydrated products such as slimming aids, and in the manufacture of paper and textiles. It is also used for waterproofing and fireproofing fabrics, in the food industry as a thickening agent for drinks, ice cream, cosmetics, and as a gelling agent for jellies, known by the code E401.[8] Sodium alginate is mixed with soybean flour to make meat analogue.[citation needed]

Alginate is used as an ingredient in various pharmaceutical preparations, such as Gaviscon, in which it combines with bicarbonate to inhibit gastroesophageal reflux. Sodium alginate is used as an impression-making material in dentistry, prosthetics, lifecasting, and for creating positives for small-scale casting.

Sodium alginate is used in reactive dye printing and as a thickener for reactive dyes in textile screen-printing.[citation needed] Alginates do not react with these dyes and wash out easily, unlike starch-based thickeners. It also serves as a material for micro-encapsulation.[9]

Calcium alginate is used in different types of medical products, including skin wound dressings to promote healing,[10][11] and may be removed with less pain than conventional dressings.[citation needed]

Alginate may be used in a hydrogel consisting of microparticles or bulk gels combined with nerve growth factor in bioengineering research to stimulate brain tissue for possible regeneration.[12] In research on bone reconstruction, alginate composites have favorable properties encouraging regeneration, such as improved porosity, cell proliferation, and mechanical strength, among other characteristics.[13]

Alginate hydrogel is a common biomaterial for bio-fabrication of scaffolds and tissue regeneration.[14]By the covalent attachment of thiol groups to alginate high in situ gelling and mucoadhesive properties can be introduced. The thiolated polymer (thiomer) forms disulfide bonds within its polymeric network and with cysteine-rich subdomains of the mucus layer.[15] Thiolated alginates are thus used as in situ gelling hydrogels[16]and as mucoadhesive drug delivery systems.[17]

Algin, a salt of alginic acid extracted from kelp, and gelatin, produced from animal bones and skins, are used as stabilizing agents in the manufacture of ice cream and in certain other food products. Studies were conducted over a period of 10 weeks to determine the nutritive effects of the vegetable gum of algin and the protein of gelatin.

The apparent digestibility of algin varied directly with the level fed. Algin was utilized efficiently after absorption. Gelatin was highly digested irrespective of the level fed, but more food was required per unit increase in live weight. No characteriztic symptoms were noted that couldbe attributed to acute or chroninic toxicity. Both algin and gelatin were found to be wholesome foods.

In this review, we aim to provide a summary of recent research advancements and applications of algin (i.e., alginic acid) and alginate-hybrid materials (AHMs) in medical fields. Algin/alginate are abundant natural products that are chemically inert and biocompatible, and they have superior gelation properties, good mechanical strengths, and biodegradability. The AHMs have been widely applied in wound dressing, cell culture, tissue engineering, and drug delivery. However, medical applications in different fields require different properties in the AHMs. The drug delivery application requires AHMs to provide optimal drug loading, controlled and targeted drug-releasing, and/or visually guided drug delivery. AHMs for wound dressing application need to have improved mechanical properties, hydrophilicity, cell adhesion, and antibacterial properties. AHMs for tissue engineering need improved mechanical properties that match the target organs, superior cell affinity, and cell loading capacity. Various methods to produce AHMs that meet different needs were summarized. Formulations to form AHMs with improved stability, drug/cell-loading capacity, cell adhesion, and mechanical properties are active research areas. This review serves as a road map to provide insights into the strategies to develop AHMs in medical applications.

Alginate, or algin, is found in the cell walls of brown seaweeds. Algin contains healthy amino acids and other benefits. Combined with fruit extract (acerola) which has more vitamin C than an orange. Imagine natural acerola and algin with its cellular amino acids in a warm nourishing mask. This mask peels off in a single layer to be removed easily and quickly!

In China, algin production was initiated in 1957 inQingdao from Sargassum pallidum. From the late 1960'sLaminaria japonica has been used for algin production in placeof Sargassum, since Laminaria was cultivated on a large scale.

The major part of commercial algin is produced from thespecies of Macrocystis, Laminaria, Ascophyllum, Eisenia,Nereocystis, Lessonia, etc. The main commercial sources ofalginophyte are shown in Fig. 22 and the main countries usingthem are shown in Table 16.

The content and viscosityof alginates in thebrown seaweed varies with theseasons, usually the contentincreasing from little amountat young stage to the maximumat the mature stage, and itsviscosity approximately changingparallel to the content.Fig. 23 illustrates the variationof the content of alginatein Laminaria japonica, andFig. 24 shows that of the content and viscosity in Sargassumpallidium (Ji et al., 1962, 1963). The latter has been used foralgin production in the initial stage and the former is beingused now in China.

Since Stanford discovered the alginic acid in 1881,till 1955 through huge amount of research work on the chemicalcomponents by lots of scientists, it has been verified thatalginic acid is a linear polymer composed of 1, 4-linked β-D-mannuronicacid residues. In 1955 Fischer found anothercomponent, α-L-guluronic acid in alginic acid in addition to D-mannuronicacid by paper chromatographic technique. He pointedout that M/G ratios vary with different species of brownseaweeds. Studies later showed that the chains of 1, 4-linkedα-L-guluronic and β-D-mannuronic acid are stereochemically verydifferent as a result of their difference at C-5. It was furtherdemonstrated from X-ray studies on the fibers of polymannuronicacid and those from alginic acid rich in guluronic acid contentthat the spacings along the fiber axis of 10.35 Å for mannuronicpolymer and 8.72 Å for guluronic polymer. Conformations of theuronic acid units in agreement with these spacings are Cl for the1, 4-linked β-D-mannuronic acid units and lC for the 1, 4-linkedα-L-guluronic acid units. M block is linked diequatorially at C-1and C-4, it is a relatively straight polymer, like a flat ribbon,while the G block is formed from diaxial groups at both C-1 andC-4, so the resulting chain is buckled (Fig. 25). 041b061a72
