Oyster Extract: Testosterone and Virility Booster

Anabolic Health follows strict standards of editorial integrity to help you make health choices  with confidence. Some of the products we feature are from our partners. Here’s how we make money.

By using pregnenolone cream or pregnenolone supplements, the levels of the compound in the body increases, and this brings about various benefits such as fatigue relief, and delay of the aging process.

One particular testosterone booster is getting great reviews and yielding positive results lately. It’s called oyster extract.

However, is it really potent when it comes to increasing energy levels, both at the gym and in the bedroom?

Well, you’ll have to consider that testosterone is a key male hormone and an essential anabolic element. It improves libido, enhances muscle recovery, and helps build lean muscle mass.

Let's take a look at how oyster extract could help with your testosterone levels.

What Exactly Is Oyster Extract?

Oyster extract is basically dried up and powdered oyster meat stuffed into capsules or tablets for easier consumption.

If manufactured with consideration to the time of harvest, oyster extract contains all 59 trace elements needed by the body. It's also loaded with amino acids and omega-3 and omega-6 fatty acids.

Oyster is also known as the best natural source of zinc. Zinc is an essential mineral both for general health and testosterone production.

The use of oyster extract isn’t new though. Eastern folks have been taking it for centuries as a remedy for erectile dysfunction and liver cleansing.

However, only in recent decades have medical and scientific research proven that oyster, particularly its zinc content, is beneficial to health.

In fact, zinc controls the reaction of more than 300 enzymes in the human body. These enzymes affect the way we think, feel, and look.

Who Needs More Oyster

Men who are not getting enough zinc may take oyster extract as a health supplement.

However, how would you know if you’re likely deficient in this particular nutrient?

Simple! Just go through this checklist:

  • You’ve been consuming too much alcohol.

    Excessive alcohol intake causes the kidneys to excrete high amounts of zinc, meaning you end up flushing down your supplies of the mineral.
  • You’re currently on a vegan or vegetarian diet.

    Zinc can only be found in minimal amounts in non-animal food sources. Extensive and careful planning is often necessary to continuously meet the recommended daily intake (RDI) for zinc when on such diets.
  • You’ve already hit your golden years.

    Zinc absorption drops as we age. And so, the unfortunate truth is that the older we get, the less zinc we get from the food we eat.

    This further highlights the need for supplementation.
  • check
    You’re into bodybuilding or intense athletic pursuits.

    Zinc is released through perspiration—in other words, the more you sweat, the less zinc you have available. To stay perfectly healthy, you’ll need to keep up with the amount you’re losing.
  • check
    You’re sexually active.

    Each time you orgasm, you lose roughly 5 milligrams of zinc and your testosterone drops a bit. Oyster extract, being a source of zinc and a T-booster, is well suited for supporting your adventures in the bedroom.

    Fun fact! Giacomo Casanova, the legendary 18th century lover, supposedly ate 50 oysters for breakfast and several dozens more throughout the day. Now you know why. 😉

Perks to Ponder Upon

Regardless of your lifestyle choices, dietary habits, and age, you may still enjoy the many perks associated with oyster extract. Do note, however, that the extent of these benefits may vary from one person to another.

Boosts Energy

Oyster extract is an excellent source of glutathione, meaning it can help indirectly in reducing oxidative stress—something that can cause fatigue, especially among with demanding lifestyles.

Some of the most stressed-out individuals include athletes and employees. Still, anyone who’s often exposed to chemical and environmental stress (e.g. smoking, alcohol consumption) is likely to benefit from a potent antioxidant.

Improves Sexual Performance and Virility

Testosterone greatly affects sexual health and oyster extract provides the body with the required nutrients for the production of this hormone, such as vitamin D and zinc.

Erectile dysfunction and impotence are common to men aged 60 and above. It’s a good thing that oyster extract can help improve sperm quality, increase sperm count, and even prevent prostate swelling.

Enhances Immunity

Oyster extract has been proven to boost the immune system by giving the body additional vitamin C. As you may know, this vitamin is a powerful antioxidant.

The high zinc content of the oyster extract also improves the body’s production of immune cells, making it more capable of fighting off both bacteria and viruses.

Supports Heart Health

Heart issues are common in aging men, so they could benefit from a supplement that would keep their cholesterol within the healthy range. Oyster extract can improve lipid metabolism, which in turn can help with chronic high blood pressure.

Slows Down Aging

Antioxidants are nature’s fountain of youth as they renew the cells and protect them from free radicals that cause premature aging and disease.

Oyster extract contains antioxidants that can improve keratin and collagen production for younger-looking hair, skin, and nails.

Zinc and Antidepressants

People who take antidepressants are prone to many of their side effects.

One of them is a significant decrease in energy levels. Since antidepressants are designed to calm the patient, this can also lead to feelings of tiredness and fatigue.

A study was carried out by Japanese doctors on a group of patients that included both individuals diagnosed with depression and those not suffering from the condition. Each of the subjects was given specific doses of oyster extract.

After only a few days, all subjects exhibited increased energy levels and there were no rebound scenarios even after the trial. The ones with an existing diagnosis showed reduced markers for depression.

Both depressed and healthy subjects didn’t experience any adverse side effects. They all felt that their energy increased and that their feeling of fatigue disappeared.

Simply put, oyster extract may benefit those who are currently taking antidepressants by lifting their mood and making them more energetic, possibly improving their quality of life by a large margin.

And One Last Thing...

Just to be perfectly clear, however, this particular supplement isn’t entirely incapable of causing adverse reactions. Those who have allergic reactions to seafood might get the same effect when supplementing with oyster extract.

For anyone else who isn’t allergic, well, there should be no adverse reactions when consuming oyster extract within the recommended amount. But, it’s always better to talk to your doctor before taking a new supplement, no matter how safe it may seem.

Remember that different supplements have varying amounts of oyster extract in them, despite most products being set at 500 milligrams per tablet or capsule—with Swanson’s Japanese Oyster Extract being a great example.
