Grapefruit Seed Extract abbreviated to GSE, is a supplement which is known for its ability to act as an antioxidant. The seed of a grapefruit has components that make it up at a molecular level, including flavonoids (the chief source of the antioxidant properties that Grapefruit Seed Extract has), sources of Vitamin C and E, limonoids, sterols, citric acid, and various minerals. Flavonoids are particularly useful here because they are able to neutralize free radicals that roam throughout the body doing harm to healthy cells.

Grapefruit Seed Extract Powder Concentration

This Grapefruit Seed Extract powder is considered food grade. It is extracted at proportions of 10:1 meaning that for every ten parts of grapefruit seed that the supplement is extracted from; one part of extract actually comes out, thereby increasing the potency of the resulting supplement. It has no fillers of any kind and it comes in the form of a gray powder.

Grapefruit Seed Extract Powder Side Effects

As long as suggested serving size is adhered to, Grapefruit Seed Extract powder is perfectly safe to use. However, it is possible that this supplement can result in a host of unwanted drug interactions. While most effects will likely be minor, it is always best to talk about this supplement, or any supplement, with a doctor and obtain their opinion on it before use.

Grapefruit Seed Extract Powder Solubility

First and foremost, the two different supplements, Grapefruit Seed Extract and Grape Seed Extract should not be confused. One is derived from actual grapefruit whereas the other is sourced from red grapes. Grapefruit Seed Extract may be found under the name citrus seed extract or possibly as grapefruit extract. Most find it preferable to take grapefruit seed extract in capsule form as this will get rid of any possibility of experiencing the bitter taste of Grapefruit Seed Extract. However, to make it more acceptable for the taste buds, this powder may be mixed with fruit juices. While there is not much chance of this powder losing its potency fast, it is still best to make sure to store it in an area that is free from light, heat, or moisture; elements which may cause supplements to lose their potency.

Customer Reviews

I add grapefruit seed extract to my energy drink. It is kind of brown but it taste good. Another winner for Bulk Supplements!
