Miraforte Review

Super Miraforte is the Life Extension Foundation's libido, anti-estrogen and testosterone supplement. Life Extension is one of the oldest and most reputable of the supplement manufacturers out there, specializing in anti-aging in particular, and with Miraforte they have taken aim at many of the hormonal issue that so often accompany the middle age and beyond years.

What is interesting is that Super Miraforte is very often sold to bodybuilders, because of its powers to decrease estrogen and likely slightly increase testosterone.  Chrysin has a questionable history of decreasing estrogen.  However, Life Extension seems to have supercharged it with the addition of piperine for increased absorption.  This is likely the reason that Super Miraforte has been very well-received and reviewed and is used by bodybuilders in many cases.  (I have even read that some doctors are recommending it.)

Could Super Miraforte possibly increase testosterone?  One of the key things that most older men need is Estrogen Control and Miraforte does just that.  The reason that this is so critical is that, not only will estrogen "crowd out" testosterone, but it also can directly put the brakes on the testosterone output from your Leydig cells. [1][2]  This means that Super Miraforte , by decreasing estrogen, could lead to a T increase for middle-aged and beyond males that are struggling with inflated levels of the female hormones.

ARE YOU LOW SHBG? Miroforte contains Nettle and Nettle lowers SHBG. This is usually a good thing, unless you are a Low SHBG guy. Low SHBG is a fairly common condition, linked to insulin resistance, that makes HRT tough for example. Low SHBG should be cautious about using Nettle products in my opinion. I am talking about SHBG below about 18 by the way.

CAUTION:  If you have any medical conditions or are on any medications, please consult with your doctor before taking any supplement.  Also, some men have such low T and E that their levels of estradiol are dangerously low.  See my link on Why Men Need Estrogen for more information.

Below I outline how Super Miraforte can benefit your sex life, including possibly increasing testosterone and libido and decreasing testosterone libido.

1. Chrysin. Chrysin is a known estrogen lowerer and it works by inhibiting the aromatization of testosterone to estrogen. As males age (and gain weight), an increasing percentage of their precious T is converted to E and chrysin can help.

CAUTION: Supermiraforte has been around quite awhile. However, it should be noted that one study showed Chrysin inhibiting the conversion of T4 to T3 and thus negatively impacting thyroid function. [3] This could potentially lead to weight gain, which would sabotage estrogen control.

2. Nettle. Nettle is a well-known liver protector. What is not so well known is that it also fights aromatization of testosterone to estrogen as well.

3. Zinc. Zinc remains a controversial testosterone booster as I cover in link on Zinc and ZMA. However, for those who are zinc deficient, this will likely give a boost. Remember that if you ejaculate, about a third of your zinc goes with it, so this can potentially help those who are sexually active as well.

4. Muira Puima. This herb is an aphrodisiac with a long history and some of its effects have even been documented in a few small studies. [1] Another study reported improved morning erections as well.

5. Maca.  This plant is another libido booster that I cover extensively in my link on The Superpowers of Maca.  Maca has actually been used as a food for centuries with an admirable safety profile.

6. Piperine.  This compound from pepper, as in black, boosts the absorption of many supplements and compounds. Life Extension Foundation, by including, some piperine is essentially "supercharging" their supplement for better efficacy.

NOTE:  Increasing testosterone in men can also lead to increases in nitric oxide as well as testosterone works positively on NOS (Nitric Oxide Synthase).
