yes, you need borageseed oil. It is the only significant source of GLA. Get it in bulk at:

The 16oz one will probably do you best. Store it in the freezer. Take 1-3 tea spoons per day depending on your age.
Hi,
I'm new here, and have been reading many of the posts with great interest. I saw this thread, and have been reading about oils for quite some time, so I hope you'll forgive my interruption.
As you mentioned, Borage Seed Oil does have the highest concentration of GLA. However, from what I've read, it lacks significant concentrations of other EFA's, undermining it's value when compared to other Seed Oils.
For example, Nutiva Hempseed Oil has 500 mg of GLA per Tbsp:

And it's only about $10 for a 24 oz. bottle on this site:

Comparing the cost per mg of GLA of Borage Seed Oil versus Hemp Seed Oil, we have:
For Borage Seed Oil:
3 Teaspoons of Borage = 1 Tablespoon (Tbsp)
There are 34 Tbsp per 16 oz bottle
1 Tbsp = 14 g @ 20.7% GLA = 2.9 g GLA/Tbsp
2.9 g GLA/Tbsp x 34 Tbsp = 98.53 g GLA per Bottle
$36/98.53 g = 36.5 cents / gram of GLA in Borage
****************************************
For Hempseed Oil:
There are 51 Tbsp in one 24 oz bottle
1 Tbsp = 14 g @ 3.57% GLA = .5 g GLA/Tbsp
.5 g GLA/Tbsp x 51 Tbsp = 25.5 g GLA per Bottle
$9.76/25.5 g = 38.3 cents / gram of GLA in Hemp
****************************************
So, the GLA from Hemp Oil is 38.3 cents per gram, while the GLA from Borage Oil is 36.5 cents per gram, making Hemp Oil 1.8 cents more expensive per gram of GLA than Borage.
However, according to these sites:
http://www.mountainroseherbs.com/learn/ ... borage.php
http://www.innvista.com/HEALTH/nutritio ... /intro.htm
Hemp Oil is 20% Omega 3 Alpha-Linolenic Acid (ALA), but
Borage Oil does not appear to have any ALA.
Hemp Oil is 50% Omega 6 Lineolic Acid, but
Borage Oil is only 36.8% Omega 6 Lineolic Acid.
Hemp Oil has 250 mg Omega 6 SDA (stearidonic acid, necessary to increase EPA concentrations), but
Borage Oil does not appear to have any SDA.
******************************************
So, I think you'd get more bang for your buck by buying Hempseed Oil rather than Borage Seed Oil.
