Does oyster extract increase testosterone production?
These ugly, slimy creatures of the sea have been rumored to be a great aphrodisiac for centuries. Oyster extract is now becoming popular for its supposed ability to increase testosterone levels. The oyster extract contains the highest concentration of bioavailable Zinc in addition to other important trace elements.
Eating oysters or consuming oyster extract improves the absorption of zinc especially. Zinc is highly linked to sperm and testosterone production and regulates well over 300 different enzymes in the male body.
Oyster extract is a rich source of zinc and vitamin D that stimulates the development and secretion of testosterone in the body. Regular supply of zinc and vitamin D in men can lead to improved testosterone levels.
According to the Indian Journal of Urology in 2006, oyster meat provides endurance, improves nerve function, and maintains the male reproductive system, as attributed also to the amino acid taurine.
Oyster extract is such a unique supplement because of its combination of micronutrients. Companies have to specially blend half a dozen or more ingredients just to get the same nutrients available in oyster extract. This supplement contains all 59 of the trace minerals your body needs, along with taurine and omega 3 and 6 fish oils. It’s also the highest natural source of zinc, which is excellent for prostate health, immune system and libido.
The bad news is there are very few reports with clinical studies on Oyster extract. But many successful studies have been done on on the effect of Zinc (the main constituent of the Oyster extract).
Benefits of zinc supplementation include
- Increases Testosterone production
- Sperm Motility
- Reduces risk of Prostate Cancer
- Helps fight acne
- May prevent or treat baldness
- Boosts your immune system
Researchers at Wayne State University School of Medicine Study on Zinc in Michigan looked into the impact of zinc on testosterone levels in males between the age of 20 to 80 years old.
The study demonstrated that young men who limited zinc intake for 20 weeks suffered from a reduction in testosterone levels while elderly men deficient in zinc taking supplements for six months benefited from an increase in testosterone production.
Since there is a lack of studies on actual oyster extracts it’s important to understand the process of how these extracts are created.
How Oyster Extract Is Made
Even though oyster extract is one of the highest bioavailable sources of zinc. The extracts are a tricky supplement to buy. The extracts are made from oyster meat that has been dried and turned into a powder then put into capsules.
The larger the oyster meat is the less zinc it will contain. So all supplements aren’t equal. Some companies may use large oyster meat. Also, oyster supplements that are in tablet form have binding agents added which have no value to you nutritionally. Some companies include the oyster shell in their product which results in a very weak oyster extract. These are quite low in potency.
The more reliable extracts may be a bit more expensive than the cheaper brands, if you are swinging towards a cheaper brand you might as well just buy a high-end zinc supplement.
If not oyster extract What’s some other Zinc Supplements?
If you choose enough of the right zinc-rich foods, you probably won’t need to worry about taking a zinc supplement. However, if you decide you could benefit from one, the available types are zinc acetate, zinc chelate, zinc gluconate, zinc picolinate, and zinc sulfate. Zinc chelate is a form of zinc that allows for easy absorption.
It makes sense that oyster extracts should boost your testosterone levels due to oysters containing some of the highest concentration of bioavailable Zinc. But how effective oysters are in an extract form has yet been proven. If you are looking for a supplement the fact is you might be safer just to purchase a high-quality zinc supplement.
