Can Onions Really Boost Testosterone

Can Onions Really Boost Testosterone

Is onion really the secret  to upping testosterone levels?

If you want to ensure your testosterone levels are in the best possible shape, there are numerous things to look at: diet, lifestyle, supplementation and how much you’re working out – and that’s just for starters.

But as the old saying goes: you are what you eat, and what we’re consuming day-to-day really does play a fundamental role in whether we’re hitting our T targets or not.

One foodstuff we repeatedly see linked to high testosterone is onion – but are there any proof points behind the gossip?

Trailing Testosterone Levels

It’s no secret that as we men age, our T levels drop – research has proven that once men reach the age 30, testosterone drops by around 1% each year.

This can have various implications: muscle loss, weight gain, slips in strength level and loss of libido are often cited as side effects of dwindling T levels. That’s where diet comes into the equation – eating the right stuff can have a surprisingly big effect on testosterone levels.

The Humble Onion

Allium cepa, onion bulb, is native to Asia but is today a global staple in cuisines far and wide – in fact, it’s only of the most highly consumed vegetables in the world. Onion production currently sits at a massive 44 million tonnes per year, coming second only to tomatoes.

Onions are considered a healthy choice thanks to their low calorie count and healthy counts of vitamins B and C. They’re also full of fibre, potassium, calcium and magnesium. You’re also looking at two important things here:


What’s more, onions are a powerful source of antioxidants, especially flavonoids. These are a type of polyphenol, which help boost digestive health and lower the chances of various cardiovascular and neuro-degenerative diseases. They also support weight management and give a powerful boost to overall health and wellbeing.


The quercetin compound is a powerful antioxidant with strong anti-inflammatory properties. Indeed, tea leaves are the only other foodstuff you’ll find containing as much quercetin. This compound has proven in clinical trials to lower the absorption of fatty acids, protect against free radical damage and help fight cancer.

Onion and Testosterone

But onions also perform where it really matter – boosting T levels.

Studies show that onion juice delivered to male rats for 20 days saw a 300% rise in testosterone levels, while luteinizing hormone levels also rose. This hormone plays an important role in stimulating the production of testosterone in the testes, as well as boosting sperm mobility.

Onions have also proven to increase the size of the testes – a 1967 study Plant Foods for Human Nutrition found that rats fed onion juice saw their testes increase in size by 25%, along with higher semen levels.

A similar study saw 162 rats given varying amounts of zinc and onion, both separately and together.  When the two were combined, T levels saw large increases.

What are my Options?

We can’t imagine many people being happy to incorporate onion juice into their diets – so why not consider a zinc supplement? It’s clearly a proven T booster, and seriously ups its impact when combined with onions in your diet. There’s also supplementing with D-aspartic acid to raise levels of luteinising.

Then there’s Prime Male, a supplement proven to increase testosterone levels without grossing yourself out with onion juice. High In Both D-aspartic acid and Zinc to name couple of its power packed ingredients, this best-in-class T booster is packed full of the nutrients you need to feel great –
