5 Best Aromatase Inhibiting Supplements (OTC AI's)

AREA-1255's Recommended OTC - OverTheCounter - Aromatase Inhibitor Supplement's




1.) PES Erase Pro

The main ingredient in Erase is still pretty much the same.
"Dehydroabietic Acid"
Abieta-8,11,13-trien-18-oic acid (DHAA)

It's a very potent aromatase inhibitor.
Boerhaavia Diffusa (Root) Extract
This extract (Boerhaavia Diffusa) has calcium channel antagonistic properties and may lower blood pressure.
It also has AI/SERM like properties. It also antagonizes alpha-2-receptors and thus will improve fat loss in "problem areas".

It also contains Cat's Claw extract. Which improves lipid profiles, increases immunity, blocks MAO enzymes and stimulates the CNS.

BACK TO THE MAIN INGREDIENT. DHAA. 

IC50 means the concentration which inhibits half of the aromatase enzyme. So the lower the IC50, the more potent the aromatase inhibition. The IC50 of dehydroabietic acid is 0.3 mu. M. (mu = micro). This is in comparison to an IC50 of 6.5 mu for 3-OHAT, 0.43 mu for 6-oxo, and 0.6 mu of formestane. The lower the IC50, the more potent the compound is at inhibiting aromatase. The previous rendition of Erase used a compound with a slightly lower IC50 value, but it was very close, making this a moot point. Why? Because one can simply use a higher dose of DHAA (>75 mg per day) to compensate and exceed the differences in potency. DHAA also comes with several additional effects (read below).

So it's clear why PES Erase Pro is number one on the list. A diversity of potent and proven ingredients and overall health support.

#2.) SNS INHIBIT-E

Contains the famous "Suicide Inhibitor" known as "ATD" or 1,4,6-Androstatriene-3,17-dione

                                                 http://www.ncbi.nlm.nih.gov/pubmed/7472286


         #3.)iForce Nutrition "Intimidate SRT"

Though not exclusively an AI, it does have a strong one.
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2748821/

Standardized for "Dehydrololiolide"

#4.) Driven Sports "Triazole"

Always liked the fact that they added Vitamin D and other important nutrients / co-factors that aid natural aromatase inhibition. As the above "Intimidate" this also has a similar extract and it happens to modulate the "aryl hydrocarbon receptor" and increases sTAR and other important steroidogenic proteins.
The CAPE (Bee Propolis Extract) acts as a natural SERM to increase LH/FSH output and increase testosterone levels.

#5.) "A-HD"
