Does LEF test for phytanic acid? This patent application says that fish oil supplements, even the purified and concentrated kind, have large amounts of it. It also makes a huge list of all the ways that phytanic acid is bad for you, and one way is prostate cancer.

Some epidemiology backs it up.

They now are scaring people that fish oil supplements have large amounts of this bad acid, but the studies below say the main source of Phytanic are red meat and dairy products.

The question has been forwarded to Life Extension's Product Development department.  Their reply will be posted as soon as it is received.

Product Development states that the finished product is not tested for phytanic acid.

According to the patent, fish oil supplements have 44-206 mg phytanic acid per 100 g. So 4 g of fish oil yields 1.76-8.24 mg phytanic acid. According to the epidemiology, the only safe group was the lowest quartile which averaged 61 mg phytanic acid per day. There's no way of telling if there was a risk gradient within that quartile, so we don't know the safe dose.

I decided to cut back to 2 grams of LEF's 60% n-3 oil per day, since my only justification for 4 grams was the Japanese epidemiology showing that 2.1 g n-3 per day prevents nonfatal heart attacks. I have no risk factors for or family history of heart disease, so 4 g no longer seems justified.

It seems highly unlikely to me that the minor amount of Phytanic Acid in fish oil, compared to ordinary diatary amounts, could have any marked effect on prostate cancer risk. Certainly it wouldn't explain the purported risk increase in that bogus British study.

Smells to me like someone wants to sell a pointless patent Wink

If it's just down to the fish oil why not cut out the middleman (or fish)
