Oregano, botanically called Origanum vulgare, belongs to the mint family of aromatic herbs. It is mostly used as culinary ingredients especially in Italian cuisine due to its exquisite fragrance and flavor. Oregano has also been historically utilized by the ancient Greeks and Romans as a vital medicinal herb. Actually, oregano means “mountain delight” in Greek. 

There are two types of oil that can be extracted from Oregano plants: first, the essential oils, which are distilled by steam from air-dried shoots and leaves, then externally used as effective topicals. The other is the oregano oil extracts, which are obtained using alcohol compounds and carbon dioxide, then processed into supplements usually in capsules or tablet form.

Oregano contains three essential components that are potent antioxidants and provide its fragrance. 

  • Carvacrol – a phenol is known to mitigate the growth of harmful bacteria and aid in lowering cholesterol levels.
  • Thymol – a potent natural antiseptic agent with antibacterial and antifungal properties that provide immune system support and protection against toxins.
  • Rosmarinic acid – a potent antioxidant that protects against free-radical damage effects.

Due to the vast number of applications and benefits that oregano oil has, it is no surprise that several health supplement companies offer their brand in the market. Choosing the best oregano oil supplement perfect for your requirements can be a daunting prospect.

In this guide, we will present our top ten brands and all the necessary factors we considered in making the optimal choices. We will also give you a rundown of oregano oil’s benefits and uses, as well as its potential side effects. Lastly, we will answer some frequently asked questions, and give our recommendations at the end.

How we ranked

There are a lot of oregano oil supplements flooding the market, and each of them pledges to be the best brand. We know that choosing the best oregano oil supplement for your needs can be very challenging, so, we give you a list of the criteria we used to evaluate each product.

Brand promise

Is the brand promising to instantly lower your cholesterol levels in merely a few days, just by taking a few softgels or drops? Be watchful of brands making outrageous claims. Remember that wellness and overall healthy body function is not an overnight success, but a slow and demanding effort.

Brand character

Are you familiar with this company or brand? Are they known in the health and wellness industry? Maybe you know an acquaintance or a friend who is familiar with them? You can check them out in Better Business Bureau or Trustpilot to make sure there is nothing doubtful about the brand before making any decisions.

Product format

Many oregano oil supplements come in vegan soft gel form, while others come in liquid drops. The method and form doesn’t influence the product’s effectiveness so that you can make any choice according to your preference.

Quantities and amounts

Always be mindful of the number of capsules or tablets per serving, as well as per container. This step also applies to products in liquid drop form. All those features affect the overall product value.

Value for your money

At times, the price can be an indication of quality or, in the case of supplements, potency; if it is very low compared to other brands, the dosages may not be enough or include unproven components. On the other hand, if it is too expensive, it should have the correct amounts of essential ingredients.

GMO-free

A critical factor, the oregano oil supplement must not contain any genetically modified organism.

Presence of metallic compounds and allergens

Oregano plants are naturally grown or cultivated. As such, there should be no heavy metals present. Another vital indication is the absence of allergens like gluten, dairy, egg, fish, soy, and others. Although most oregano oil supplements are blended with extra virgin olive oil, for better intestinal absorption, it does not pose as a hazardous allergen. However, some brands use different compounds such as fennel and ginger oils, which could induce possible allergic reactions.

FDA/cGMP certifications and approvals

It is crucial to discern that a product contains safe and high-quality ingredients. One perfect way to find out is by checking if the products are made in cGMP/FDA approved or certified facilities and processes. There are other third-party certifications and seals for other essential matters about ingredients and components. Some of these are laboratories that certify purity and potency.

User comments

In case you do not have acquaintances that have tried the product before, you can check out websites like iherb.com or Amazon, as well as other online sites associated with health and wellness campaigns.

How Do I Choose the Best Oregano Oil Product?

Only very few studies about oregano oil exist, so it is difficult to establish what the product‘s optimal formulation is. At the end of the day, everything would depend on your budget, requirements, and preferences. Moreover, brand reliability is an essential consideration, as quality and effectiveness greatly vary from one product to the next, especially within the supplement world. The best and safest way is to select a product coming from a reputable manufacturer.

Most of the excellent oregano oil supplements come with fair prices and are well-reviewed as well. Check to see how much you get for the price the company is asking. Some companies make you pay more for less.

Benefits of Oregano Oil

Oregano oil could be used topically or as a health supplement. It has potential anti-inflammatory, antiseptic, and cholesterol-reducing advantages that provide it several uses. However, the benefits have to be studied further to prove their viability. Here are the potential uses of oregano oil:

Cholesterol 

Oregano oil contains a bioactive compound called carvacrol, which is widely known to offer some help in combating high cholesterol, as shown in one study on mice. That means Oregano oil could help reduce human cholesterol levels, but would necessitate substantially more research using human subjects.

Immunity 

Containing compounds known to have antifungal and antibacterial properties, Oregano oil can help our bodies ward off against bacterial, fungal, and parasitic invasions. The antioxidants of effective Oregano oil supplements may also aid in protecting our immune system against damages caused by free radicals, boosting its efforts to function better. Unfortunately, further research is necessary to provide evidence on human benefits.

Antioxidant

Being an essential oil rich in antioxidants, Oregano oil can aid in slowing the process of aging by reducing free-radical damages of cells. Potent Oregano oil supplements may contain high antioxidant concentrations, amounting to about 400% of that present in blueberries. But due to the limited number of researches about human supplementation, it would be difficult to determine the extent  of supplement benefit.

Skin

Oregano oil has topical uses for skin issues like acne, athlete’s foot, canker sores, dandruff, oily skin, psoriasis, rosacea, warts, and even insect bites. Studies have not proven if the oil has been effective on any of the mentioned applications, so further research is required.

Side Effects of Oregano Oil

Oregano oil, if not properly administered, can cause upset stomachs. For individuals suffering from allergies to plants from the mint group, Oregano oil may induce allergic reactions.

Oregano oil is not recommended for pregnant or lactating women, persons with pre-diagnosed medical conditions, and children. Overall, it would be best to consult your doctor before taking oregano oil supplements especially if you are currently under medication.

Recommended Dosage

There is a unique study using oregano oil for human oral supplementation, which administered 600mg once each day. The advisable way is to take the supplement with food, preferably a meal. Of course, the best way is still by following the manufacturer’s recommended dosage, or the advice provided by your doctor or health care specialist.
