spring when natural series 1 eicosanoid levels are low, often need this
supplement. GLA is also essential for carrying calcium to muscle and
bone cells. Without it, the calcium in your diet won’t be as useful and
some may be stored as calcium deposits. Borage oil and evening
primrose oil also contain GLA. It’s important when taking any prod-
uct containing GLA to also take EPA (fish oil) or raw sesame-seed oil.
These oils help prevent GLA from ultimately converting to arachi-
donic acid, which promotes inflammation. Both sesame and all the
GLA-containing oils are also very sensitive to oxygen, and should be
