Algin

Background

Algin is a type of carbohydrate found in brown seaweeds. It is also made by some bacteria. Algin is used as a food additive. It is also used to make certain health products such as tablets, lozenges, and peel-off facial masks. Algin is also as a medicine.

People use algin to lower cholesterol and blood pressure, and to reduce the amount of heavy chemicals that are taken up by the body, but there is no good scientific evidence to support these uses.
When taken by mouth: Algin is LIKELY SAFE when used in food amounts. The safety of larger medicinal amounts is unknown.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if algin is safe to use in medicinal amounts when pregnant or breast-feeding. Stay on the safe side and avoid use.

Effectiveness

Natural Medicines rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.
Likely effective Effectiveness definitions
Possibly effective Effectiveness definitions
Likely ineffective Effectiveness definitions
Possibly ineffective Effectiveness definitions
Insufficient evidence Effectiveness definitions
  • Lowering cholesterol.
  • Lowering blood pressure.
  • Decreasing the amount of the certain heavy chemicals taken up (absorbed) by the body.
  • Other conditions.
More evidence is needed to rate the effectiveness of algin for these uses.

Interactions with herbs & supplements

Calcium: Algin, also known as alginate, might slightly reduce the amount of calcium that the body absorbs.
Chromium: Algin, also known as alginate, might reduce the amount of chromium that the body absorbs.
Copper: Algin, also known as alginate, might reduce the amount of copper that the body absorbs.
Iron: Algin, also known as alginate, might impact the amount of iron that the body absorbs.
Strontium: Algin, also known as alginate, binds with strontium and keeps it from being absorbed well by the body. This effect has been used to reduce strontium absorption and toxicity in cases of poisoning, but it might also affect the absorption of strontium supplements.
