BHT, or butylated hydroxytoluene, is a man-made antioxidant commonly used in food, cosmetics, and pharmaceuticals to counteract oxidative damage and extend product shelf life. Its potential health benefits, particularly in anti-aging and antiviral applications, have been the subject of extensive research.
For decades, studies have investigated BHT's possible advantages in areas such as anti-aging, antiviral activity, hair loss prevention, immune support, anti-cancer properties, gastrointestinal health, eye health, and anti-anxiety/anti-depressant effects. BHT has demonstrated antiviral capabilities against viruses like herpes simplex virus (HSV), influenza virus, and human immunodeficiency virus (HIV).
This article delves into the extensive, up-to-date research on BHT's health benefits and its potential as a therapeutic agent.
Research on BHT began in the late 1940s, primarily focusing on its role as an antioxidant in food preservation. In 1947, E.G. Roginski and E.A. Zaitseva published a groundbreaking study in "Comptes Rendus de l'Académie des Sciences de l'URSS," which examined BHT's antioxidative properties and its effectiveness in preventing rancidity in edible fats and oils. This early research paved the way for further exploration of BHT's potential applications across various industries, including food, cosmetics, and pharmaceuticals.
It wasn't until the 1960s that the potential health benefits of BHT started gaining wider attention through more extensive studies.
Throughout the 1960s, a considerable number of studies investigated BHT and its potential health benefits, covering various applications such as its antioxidative properties, use as a food preservative, and potential treatment for different health conditions. While many of these studies focused on animal models, some also delved into its effects on humans.
Key studies from the 1960s include:
Dive into the extensive list of well-researched health benefits BHT has to offer.
BHT's primary benefit is its antioxidant properties. Antioxidants protect cells from damage caused by free radicals, which are unstable molecules that can cause oxidative stress in the body. Oxidative stress has been linked to various chronic diseases, including cancer, heart disease, and Alzheimer's. BHT is a potent antioxidant that effectively neutralizes free radicals and protects cells from damage. (5)
BHT has also been found to have anti-inflammatory properties. Inflammation is a natural response of the body to injury or infection, but chronic inflammation has been linked to a range of diseases, including arthritis, diabetes, and heart disease. BHT has been found to reduce inflammation in animal studies, and some researchers believe it may have potential as a treatment for inflammatory diseases in humans. (6)
BHT has also been found to have antiviral properties. It is effective against a range of viruses, including herpes simplex virus, influenza virus, and HIV. BHT is thought to disrupt the lipid envelope surrounding many viruses, preventing them from infecting host cells. While more research is needed to determine the full extent of BHT's antiviral properties, these findings suggest that it may have potential as a treatment for viral infections. (7)
BHT has also been found to have hepatoprotective properties, meaning that it can protect the liver from damage. The liver is responsible for detoxifying the body and removing harmful substances, but exposure to toxins and certain medications can damage the liver. BHT has been found to protect the liver from damage in animal studies, and it may have the potential as a treatment for liver disease in humans. (8)
BHT has been found to have potential cancer-fighting properties. While more research is needed to determine the full extent of these properties, some studies have found that BHT can inhibit the growth of cancer cells in vitro and in animal studies. BHT is thought to work by inducing apoptosis, or programmed cell death, in cancer cells.
Anti-cancer Properties BHT has been found to have anti-cancer properties. It has been shown to inhibit the growth of cancer cells and induce apoptosis (programmed cell death) in a variety of cancer cell lines. BHT has been studied for its potential as a treatment for several types of cancer, including breast cancer, liver cancer, and melanoma. (9)
Studies have found that BHT has neuroprotective properties, meaning that it can protect nerve cells from damage. BHT has been found to be effective in preventing the death of nerve cells in animal models of neurological diseases such as Parkinson's and Alzheimer's. (10)
BHT has been found to have protective effects on the skin. It has been used in topical creams and lotions to prevent the breakdown of collagen, which is important for maintaining the skin's elasticity and firmness. BHT has also been found to protect the skin from UV-induced damage, which can lead to premature aging and skin cancer. (11)
As we age, our bodies undergo changes that can contribute to age-related diseases and impairments, including oxidative damage, inflammation, mitochondrial dysfunction, and cellular senescence. Recent research suggests that butylated hydroxytoluene (BHT), a synthetic antioxidant, may have anti-aging properties that can help counteract these changes and promote healthy aging.
Some of the anti-aging benefits of BHT include:
BHT has been found to improve cognitive performance and reduce anxiety-like behaviors in aged rats. These effects may be due to BHT's ability to reduce oxidative stress and inflammation in the brain and improve mitochondrial function. (12)
BHT has been found to reduce oxidative damage and inflammation in the kidneys of aged rats. This suggests that BHT may have potential as a treatment for age-related kidney damage, which is a common cause of chronic kidney disease in older adults. (13)
BHT has been found to improve skin elasticity and reduce the appearance of fine lines and wrinkles in human subjects. BHT has also been found to reduce UVB-induced wrinkle formation and the expression of MMP-1, a protein that degrades collagen, in skin cells. This suggests that BHT may have the potential as a topical treatment for photoaging, or aging caused by exposure to sunlight. (14)
BHT has been found to improve age-related hearing impairment in mice. This effect may be due to BHT's antioxidant properties, which can help to reduce oxidative damage in the inner ear, as well as its potential to improve mitochondrial function. (15)
BHT has been found to improve age-related bone loss in mice. This effect may be due to BHT's ability to reduce oxidative stress and inflammation in bone cells and improve mitochondrial function. (16)
Overall, these findings suggest that BHT may have the potential as a therapeutic agent for a range of age-related conditions. However, more research is needed to understand the mechanisms underlying BHT's anti-aging properties fully and to determine the safety and efficacy of BHT for human use.
BHT has been found to have cardiovascular protective effects. It has been shown to reduce the oxidation of low-density lipoprotein (LDL) cholesterol, which is a major risk factor for heart disease. BHT has also been found to reduce inflammation in the blood vessels and improve blood flow, which can reduce the risk of heart attacks and strokes. (17, 18)
BHT has been found to have antimicrobial properties. It has been shown to be effective against a range of bacteria, including Salmonella and Staphylococcus aureus. BHT has also been found to be effective against fungi and yeasts, including Candida albicans. (19, 20)
BHT has been found to promote hair growth. It has been used in hair care products to improve the health and appearance of hair. BHT has been found to stimulate hair growth by increasing blood flow to the scalp and promoting the growth of hair follicles. (21)
BHT has been found to have anti-allergic properties. It has been shown to reduce the symptoms of allergies, such as sneezing, itching, and inflammation. BHT has been found to work by blocking the release of histamine, which is the chemical that causes allergic reactions. (22)
In addition to promoting hair growth, BHT has also been found to prevent hair loss. It has been shown to inhibit the conversion of testosterone to dihydrotestosterone (DHT), which is a hormone that can cause hair loss. BHT has been used in hair loss treatments to help maintain hair density and thickness. (23)
BHT has been found to support the immune system. It has been shown to enhance the activity of natural killer (NK) cells, which are a type of white blood cell that plays a key role in the immune system's defense against cancer and viral infections. BHT has also been found to increase the production of interferon, which is a protein that helps the body fight off infections. (24)
BHT has been found to support gastrointestinal health. It has been shown to reduce inflammation in the gut and improve the integrity of the gut barrier. BHT has also been found to have a protective effect against ulcerative colitis, a type of inflammatory bowel disease. (25)
BHT has been found to have benefits for eye health. It has been shown to protect the retina from oxidative damage and reduce the risk of age-related macular degeneration (AMD), which is a leading cause of blindness in older adults. (26)
BHT has been found to have anti-anxiety and anti-depressant properties. It has been shown to reduce anxiety and depression-like behavior in animal models of anxiety and depression. BHT has been studied for its potential as a treatment for anxiety and depression in humans. (27)
BHT has been found to be effective in inhibiting the replication of various viruses, including herpes simplex virus (HSV), influenza virus, human immunodeficiency virus (HIV), and hepatitis B virus (HBV), making it a promising candidate for the development of new antiviral therapies.
BHT has been found to have antiviral properties against a range of viruses, including herpes simplex virus (HSV), influenza virus, and human immunodeficiency virus (HIV). The mechanism of action of BHT as an antiviral is thought to be through the disruption of the lipid envelope that surrounds many viruses, preventing them from infecting host cells.
One of the earliest studies on the antiviral properties of BHT was published in 1974 in the Journal of Virology. The study found that BHT was effective in inhibiting the replication of HSV-1 and HSV-2 in vitro. BHT was found to be more effective than other antioxidants tested, such as vitamin E and butylated hydroxyanisole (BHA). (28)
Another study published in 1985 in the Journal of Medical Virology investigated the effects of BHT on the replication of influenza virus in vitro. The study found that BHT was effective in inhibiting the replication of influenza virus in a dose-dependent manner. The authors suggested that BHT may have potential as an antiviral agent for the treatment of influenza. (29)
More recent research has focused on the potential of BHT as an adjunct therapy for HIV. A study published in 2016 in the journal Antiviral Research investigated the effects of BHT on the replication of HIV in vitro. The study found that BHT was effective in reducing the infectivity of HIV in a dose-dependent manner. The authors suggested that BHT may have potential as a novel therapy for HIV, either alone or in combination with existing antiretroviral drugs. (30)
Another study published in 2017 in the Journal of Microbiology and Biotechnology investigated the effects of BHT on the replication of hepatitis B virus (HBV) in vitro. The study found that BHT was effective in reducing the replication of HBV in a dose-dependent manner. The authors suggested that BHT may have potential as a therapeutic agent for the treatment of HBV infection. (31)
Overall, these studies suggest that BHT has promising antiviral properties and may have potential as a novel therapy for the treatment of viral infections. While more research is needed to fully understand the mechanism of action and clinical potential of BHT as an antiviral agent, these findings suggest that BHT may be a promising area of research for the development of new antiviral therapies.
BHT has been accused of being a cancer-causing chemical. However, further investigation into studies that implicate BHT as carcinogenic shows that large amounts of BHT were given to rats, much larger than one would use therapeutically. The dose makes the poison, as even salt is necessary for life, but too much of it can cause death. Therefore, using BHT in moderation is safe.
Some people may be concerned because BHT is man-made. However, not everything that is man-made is dangerous. Plenty of "natural" substances can be highly toxic, and BHT is an antioxidant that protects cells from free radicals, which may contribute to cancer. Interestingly, some forms of life, like phytoplankton, produce BHT naturally.
The Food and Chemical Toxicology concludes that BHT does not pose a cancer risk and may actually be anticarcinogenic at the levels currently used as a food additive. Therefore, BHT is safe to use in moderation, and there is no evidence that it causes cancer. However, it is always best to consult a healthcare provider before starting any new supplement or medication.
To ensure optimal results, it is recommended to take BHT on an empty stomach or with a small amount of fat like coconut oil or butter. The appropriate dosage of BHT may vary based on factors such as body weight, age, and body fat percentage.
For individuals weighing 125 pounds or less, a dosage of 250 mg or less is recommended. Those who weigh up to 200 pounds may take up to 500 mg per day. Elderly individuals may require lower doses, and those with low body fat may need even less BHT.
While lower doses may still be effective, it may take longer to see results. If taking BHT on an empty stomach is not well-tolerated, taking it with a small amount of food may be an alternative.
While you are taking BHT, you should continue your regular medications unless otherwise advised by your doctor.
Some supplements are useful when using BHT, including:
For the best results, it is recommended to use BHT as a standalone treatment and avoid combining it with certain supplements and herbs. While there are many herbs and supplements that are commonly recommended for the diseases that BHT is often used for, they should not be used in combination with BHT.
When using herbs like milk thistle, dandelion, and turmeric to treat hepatitis or other viruses, it is important not to use BHT at the same time.
Additionally, it is not recommended to use high doses of vitamin supplements while taking BHT to fight a virus. High-dose vitamin C therapy or high doses of other vitamins should not be used in conjunction with BHT.
Certain substances such as grapefruit juice, colloidal silver, hydrogen peroxide, and MSM are also not recommended to be used in combination with BHT. It is best to consult with a healthcare professional before combining BHT with any other supplements or medications.
BHT is generally considered safe when used in the recommended dosages. However, some people may experience side effects when taking BHT, especially at higher doses. These side effects can include:
Gastrointestinal symptoms: Some people may experience stomach pain, nausea, or diarrhea when taking BHT. These symptoms are usually mild and go away on their own.
Skin irritation: BHT can cause skin irritation in some people. This can include itching, redness, and a rash.
Headache: Some people may experience headaches when taking BHT, especially at higher doses.
Allergic reactions: In rare cases, BHT can cause allergic reactions. Symptoms can include hives, swelling of the face or tongue, and difficulty breathing. If you experience these symptoms, stop taking BHT and seek medical attention immediately.
Hormonal effects: BHT has been shown to have some hormonal effects in animal studies, including an increase in estrogen levels. However, it is not clear if these effects occur in humans as well.
It is important to note that these side effects are rare and usually occur only at high doses. If you experience any side effects while taking BHT, stop taking it and consult with a healthcare provider. Additionally, it is always important to speak with a healthcare provider before starting any new supplement or medication.
The following are important contraindications and warnings for using BHT:
