Grapefruit Seed Extract contamination

[Guest guest]

As has been posted on several other boards, grapefruit seed

extract has come under suspicion. Several studies have been unable to

show antifungal or antibacterial action when all natural grapefruit

components were used in extracts. Other studies found that when

commercial products like Source Naturals Citricidex (the brand

sold by Vitamin World and others) were tested they contained

substantial contaminants including solvents. One U.S. Department of

Agriculture study found that benzethonium chloride, a synthetic

antimicrobial agent comprised a whopping 8.03% of the total volume of

the commercial grapefruit seed extract sample.

It might be wise to avoid or find an alternative to the

commercial products. Benzethonium chloride is extremely toxic if

ingested.

Do you think this would include Grapeseed Oil too?
