Best Natural Testosterone Booster UK

Once a man reaches the age of thirty, the testosterone produced by his body starts to reduce by about 1% per year. The NHS refers to the low level reached by some men in their forties and fifties as ‘the male menopause’ because it’s linked to depression, low sex-drive and erectile dysfunction.

Having enough testosterone can provide all sorts of benefits including weight-loss, sperm production and building muscle mass. Eating the right foods can have a significant impact on how fast testosterone decreases and can even raise these levels. Natural testosterone boosters are an excellent way to boost testosterone building and promoting substances in our diet.

Now, testosterone boosters have become more advanced and often include a complex blend of natural substances included for several different functions. In this list, you will find the best natural testosterone boosting supplements that provide your body with everything it needs to produce testosterone, substances to promote its production and some even have compounds that can block the breakdown of testosterone.

What is testosterone?

Testosterone is a hormone found in men and women, it’s mainly made in testicles and ovaries, but women produce a much smaller amount than men. In men, it has numerous important roles, including boosting bone mass, increasing strength and supporting the production of red blood cells and sperm. Exactly how it works and how much a man requires to be healthy isn’t fully understood. There is more understanding of what it does and why it’s important, than how it works. 

Men and women can each have a wide range of levels of testosterone, and the ‘normal’ level appears to be broadly different from person to person. A blood test will tell you how much testosterone is in your blood but only how you feel and any symptoms you experience will be able to tell you whether you have enough or not.

Common symptoms of low testosterone in men are:

  • Low sex drive
  • Difficulty maintaining an erection
  • Patchy or thin body and beard hair
  • Low muscle mass
  • Long bouts of fatigue
  • Depression and anxiety

Do testosterone boosters really work?

Most testosterone boosters are designed by nutritionists based on the latest research. As a result, they include ingredients that either increase the amount of testosterone in your blood or improve the symptoms of low testosterone.

However, the effect will depend mainly on your body chemistry, health and body type. So you may find that some products suit you better than others, to increase the chance that a testosterone booster will work for you look for those that have been designed based on scientific evidence and have a broad range of beneficial botanicals, vitamins and minerals. 

Another factor that can affect how well a testosterone booster works is how well your body can absorb it. The best supplements will use wholefood ingredients or special preparations to allow the active substances to pass into your blood more effectively.

What are the most common natural testosterone boosting ingredients?

  • D-aspartic acid – This is an amino acid that promotes hormone production. It improves the release of hormones that increase the production of testosterone.
  • Vitamin D – This vitamin has strong links to good levels of testosterone production, and vitamin D deficiency is thought to contribute to low levels of testosterone in the UK.
  • Fenugreek – studies have shown that men supplementing with fenugreek showed an increase in testosterone levels.
  • Saw palmetto -This is a variety of palm that inhibits the conversion of testosterone to dihydrotestosterone. It is often used to as a natural testosterone booster and its also proven effective at reducing hair loss in men.
  • Ginger– Studies with rats have shown encouraging increases in testosterone levels after regular consumption of ginger.
  • Zinc – Studies have found that the level of zinc in men’s diets is directly linked to their levels of testosterone. Men who are deficient in zinc are likely to have symptoms of low testosterone.
  • Ashwagandha – Studies with ashwagandha showed an increase in sperm production, fertility and a 10-22% increase in testosterone levels.
  • Mucuna pruriens – This is a bean know for its incredible mood-boosting benefits and contains high levels of L-dopa, which can increase dopamine and consequently raise your levels of testosterone.

Which foods decrease testosterone?

Diet and supplementation is the key to boosting testosterone, but it also plays a role in reducing it. Several foods have been found to lower the amount of testosterone in your body dramatically. They include; soy products, polyunsaturated fats like those in vegetable oils, flaxseeds, and some types of nuts.

If you follow a vegan diet, you will likely consume large amounts of some of these daily. If you are, it may be worth looking for a testosterone booster with ingredients that block these foods from reducing the testosterone levels.

What else can I do to boost my testosterone levels

As well as eating right and using supplements, some other useful strategies may help:

Regular resistance training- Short bursts of strenuous activity like this result in quick increases in testosterone. As you build muscle, it’s likely that the effects may become longer-lasting.

Reduce stress – High levels of prolonged stress has been linked to low testosterone, so finding ways to reduce stress and increase relaxation will provide numerous general benefits, including helping your testosterone production.

Getting enough sleep- although this is easier said than done, a good nights sleep is a great way to allow your body to create enough testosterone.

Are there side effects or downsides to boosting testosterone?

Natural testosterone boosting supplements are likely to have fewer side effects than supplementing with actual testosterone. Testosterone gels were found to cause an increase in heart problems in older men.

The natural substances mentioned here are all generally well tolerated with occasional minor side effects, including headaches and nausea. Because each of the supplements listed here includes a range of ingredients, it’s essential to look carefully for anything you may be allergic too.

Too much testosterone could also cause issues in itself. Paradoxically many of the symptoms of excess testosterone are simar to those of low testosterone and include erectile dysfunction and shrinking testicles. 

If you experience any side-effects or are concerned that your testosterone levels are too high or too low, stop taking the supplement and talk to your doctor.
