Supplement ReviewsEFA (Essential Fatty Acids)EFA's may
have many benefits including improved metabolism, improve insulin
action, increased growth hormone secretion, improved testosterone
production, improved blood pressure, liver support and protection
(especially with borage oil and evening primrose oil due to their
GLA content), improved condition of hair and nails, improved
cholesterol profile, decreased inflammation response, improved nerve
function, enhanced immune function, improved energy production of
cells, and increased nitrogen retention.
Low fat
diets have been continuously shown to lower testosterone levels.
There are two types of EFAs, linoleic
acid and linolenic acid. Linoleic acid is included in the category
known as omega-6 fatty acids, while linolenic acid—specifically,
alpha linolenic acid—is an omega-3 fatty acid. Another omega-6 fatty
acid, gamma linoleic acid (GLA), is also important for health and
athletic performance. GLA has actually been shown to lower 5-alpha
reductase activity which can lower the conversion of excess
testosterone to DHT—a great added benefit! There’s a class of
“hormone like substances” called prostaglandins in the human body.
Prostaglandins are derived from essential fatty acids. There are
three classes, or series, of prostaglandins. Series 1 prostaglandins
promote performance, series 2 prostaglandins disrupt performance,
and series 3 prostaglandins block the formation of series 2
prostaglandins. Obviously, you’d just want to boost series 1 and
series 3 prostaglandins. These prostaglandins can have anabolic
effects in the body. Eating plenty of essential fatty acids,
especially monounsaturated fats, can have a positive impact on
testosterone levels. These include natural peanut butter, hemp seed
oil, flax seed oil, olive oil, and canola oil. Eating fish
including salmon regularly can also help. One study published in
the Journal of Nutrition in 1990 showed that fish oil
(containing EPA and DHA) positively impacted testosterone
synthesis. Taking 5-10 grams daily of EFA’s can be beneficial.
Quality EFA products include Udo’s Oil and Structured EFA from EAS.
