Luteolin

Luteolin

A natural flavonoid found in some of the foodstuffs we would routinely eat, but derived in manufacturing quantities from the bark of a tree found mainly in Asia. A worthy ingredient for a test booster.

This natural ingredient has shown itself to be a powerful anti-oxidant, and a potent aromatase inhibitor. You probably wouldn't supplement with it individually, but it is a worthwhile addition to a combined test boosting supplement.

Luteolin and Testosterone

Unfortunately in the world of natural testosterone boosters, some ingredients have a tendency to come and go. An exciting new component which we’re told is absolutely key to unlocking our body’s peak performance one day, might be gone the next, along with the cash we spent on it in good faith.

That’s why consistency is so often a mark of quality and why we keep an eye out for those ingredients which regularly find their way into the best testosterone supplements available. Luteolin would definitely be one such fixture. Here we’ll look at precisely how luteolin helps to stimulate our testosterone and why it remains such a popular inclusion for so many quality brands.

Luteolin is a Flavone, a type of flavonoid, which is found mainly in nature within the leaves and bark of the Terminalia Chebula tree. Before you decide to head off for your nearest forest with a chainsaw and a bottle of barbeque sauce though, it’s worth mentioning luteolin is also present in slightly more palatable vegetable options, such as celery, broccoli, carrots and green pepper, as well as herbs like parsley, thyme, peppermint and oregano.

General benefits of luteolin include it’s qualities as a potent antioxidant, helping to regulate metabolism, boost the immune system and manage type 2 diabetes.

Does It Boost Testosterone?

Luteolin’s primary function when it comes to raising testosterone is as an incredibly effective aromatase inhibitor, which means it regulates the amount of estrogen active in our system.

Despite its title of the female hormone, guys too have varying amounts of estrogen in their system at any one time. You’re probably familiar with the term hormonal balance; well testosterone and estrogen are on opposite ends of that balance, meaning that when one is plentiful the other will be in short supply.

By blocking the aromatase enzyme, luteolin stops androgens being converted to estrogen leading to lower amounts of it in in the body, which clears the way for much higher levels of testosterone. We know just how effective luteolin is thanks to a study by The Chinese Academy of Sciences which compared it against over 1,400 different natural compounds and found it be superior to all of them in its ability to reduce estrogen.

Antioxidant

As previously touched on earlier, luteolin has been shown to be a potent antioxidant. This brings with it a number of general health benefits, but also has a specific advantage with regards to our testosterone.

Often, one of the reasons for low testosterone is oxidative damage to the Leydig cells in the testes, leading to poor function, which can hinder testosterone production. Research conducted by the Department of Pharmacy at the National University of Singapore recently concluded that;

“luteolin was evaluated to possess direct and indirect antioxidant activities by scavenging free radicals and inducing the upregulation of ARE-dependent phase II enzymes.”

This makes luteolin an ideal candidate to reduce the sort of internal wear and tear that might negatively impact your ability to create testosterone.

Conclusion

So while luteolin may not aid testosterone quite as directly as the likes of D-Aspartic Acid, zinc, vitamin D3 or magnesium for example, it still has a vital role to play as sort of a personal security guard to those stars; clearing a path, making sure nothing gets in their way or stops them doing their job.

Luteolin isn’t the only ingredient with aromatase inhibiting and antioxidant qualities, but it is one of the best, particularly on that first count. Coming out on top when clinically compared to so many natural estrogen reducing alternatives explains why it is the go-to choice of a top age related testosterone booster like Prime Male.

There are always going to be fad ingredients in this industry but based on the wealth of evidence out there, luteolin was never going to be one of them.
