Cod Liver Oil

Cod Liver Oil and Acne

Cod Liver Oil, like the name implies, is oil derived from the liver of Cod fish (Gadus spp). Cod Liver Oil has been used for centuries to treat various ailments and is widely lauded for its perceived anti-inflammatory effects. Cod Liver Oil is rarely used on its own as a treatment for acne, but it is often included as a nutritional supplement in holistic Naturopathic ance treatment regimens.

Cod Liver Oil contains high levels of Vitamins A and D, as well as many important fatty acids. There is some research that suggests Cod Liver Oil can reduce blood triglyceride levels and help improve blood pressure. The high levels of Vitamin A are one of the reasons why Naturopathic practitioners  use the Cod Liver Oil to relieve their acne symptoms. Vitamin A is a retinoid and structurally-similar to anti-acne pharmaceuticals, such as Isotretinoin (Accutane) and Tretinoin (Retin-A). Vitamin A supplementation may help reduce sebaceous gland activity, which can help reduce acne symptoms in some individuals. Vitamin D supplementation may help overall immune function, especially in the winter.

Overall, there is very little clinical research on the efficacy of Cod LIver Oil for the treatment of acne. There are some people who have reported positive improvements in their acne symptoms after starting a supplement regimen that contained Cod Liver Oil. Although the available evidence suggests that Cod Liver Oil supplements are safe when used as directed, these supplements are unlikely to dramatically improve acne symptoms for most people.

Chromium Picolinate

Chromium Picolinate Tablets

Chromium Picolinate Supplements help raise the amount of chromium present in the body. Small levels of dietary chromium are essential for normal metabolic function. Chromium-deficient patients have problems with blood sugar regulation and other essential metabolic processes. Chromium picolinate is a semi-popular supplement for athletic training. Chromium Picolinate supplements are also occasionally used in Naturopathic medicine for the treatment of some skin diseases, such as acne.

Chromium Picolinate Structure
Chromium Picolinate Structure

Chromium is naturally present in small concentrations in many unprocessed foods and most people are not chromium deficient. There is little evidence that dietary supplementation with Chromium Picolinate has significant effects in people who already have healthy levels of chromium. Since there is a link between blood glucose (sugar) levels and inflammation, people have attempted to use chromium picolinate to improve their acne symptoms. The idea being that an increase in the amount of Chromium Picolinate will decrease the amount of blood glucose, which leads to decreased inflammation. This would then cause an improvement in acne symptoms. However, there does not appear to be any reliable evidence that indicates Chromium Picolinate supplements are effective as an acne treatment.

Calcium Supplement Tablets

Calcium Supplements are nutritional supplements that contain bio-available forms of elemental calcium. Calcium is an essential mineral that is most commonly used to improve bone density and limit the effects of osteoporosis. Many foods are either naturally rich in calcium (eg. Milk, Spinach) or fortified with additional calcium (eg. Breakfast Cereals). Calcium Supplements are rarely used as an acne treatment and there is no evidence that they can improve acne symptoms.

Elemental Calcium
Elemental Calcium

There are various reasons people use Calcium Supplements. They may be trying to prevent osteoporosis or even heal acne scars. However several research studies have questioned the therapeutic validity of Calcium supplementation for those ailments. Several other research studies have even linked calcium supplementation to an increased risk of cardiovascular disease and heart attacks. The increased risk could be due to the important role Calcium plays in maintaining cardiac rhythm. Hypercalcemia, or an excess of blood calcium, can even cause an ECG finding known as an Osborn Wave, which is also seen in hypothermia. Excess calcium may also cause other problems such as kidney stones or gallstones.

Nevertheless calcium is involved in many cellular processes and signaling pathways, and it is a necessary mineral. So some acne sufferers do feel that calcium supplements can maintain their skin health, control acne or even help heal acne scars. Although there is no evidence that Calcium Supplements will improve acne symptoms, they are considered quite safe when consumed at recommended levels.

Burdock Flowers 2

Burdock Supplements are extracted from the roots and seeds of the Burdock plant (Arctium spp). Most commercial Burdock supplements are prepared from the roots or seeds of the Greater Burdock (Arctium lappa), which is native to Eurasia but naturalized in many regions around the world. Burdock root is an important part of the traditional medicine of many cultures in its native range. Burdock is used in Naturopathic medicine to treat many different conditions, including acne.

Burdock Roots
Burdock Roots

For the Naturopathic treatment of acne, Burdock seed extracts are often incorporated into topical preparations. Burdock root supplements or teas may be used to ‘cleanse’ the blood in order to help heal the skin. Although there are some reports that Burdock supplements helped reduce acne symptoms, there is no robust evidence to support these claims. Burdock supplements are unlikely to significantly improve acne symptoms for most people.

Despite the lack of scientific evidence of usefulness as an acne treatment, Burdock root extract is rich in important fatty acids. Taking modest amounts of Burdock supplements may have modest health benefits for some individuals, but it is difficult to know without further scientific research. Burdock extracts can also be toxic if consumed in excessive quantities.

Alpha Lipoic Acid

Alpha Lipoic Acid (aLA) Capsules

Alpha Lipoic Acid (aLA) is a compound that is naturally made by animals during cellular processes. Alpha Lipoic Acid is important for the function of many enzymes involved in aerobic (oxygen) respiration. Alpha Lipoic Acid supplements are widely available and are purported to have antioxidant properties and other effects that are beneficial for overall health. Alpha Lipoic Acid is approved for use in Germany as a medical treatment for diabetic neuropathy (nerve damage), although it is unclear how effective it is. Alpha Lipoic Acid is rarely used for the direct treatment of acne. When used as an acne treatment, Alpha Lipoic acid may be ingested orally, or incorporated into topical anti-acne formulations.

Alpha Lipoic Acid Rich Foods
Alpha Lipoic Acid Rich Foods

Most people consume a significant amount of Alpha Lipoic Acid as part of their normal diet and it is unlikely that most people have Alpha Lipoic Acid deficiencies. There are a handful of research studies that indicate that consuming oral Alpha Lipoic Acid supplements can increase levels of Alpha Lipoic Acid in the blood, and that this might have beneficial effects. However, the connection between Alpha Lipoic Acid supplements and improvements in specific health conditions and diseases is largely unproven, and the evidence that does exist tends to be weak. There is no direct evidence that Alpha Lipoic Acid supplements have any effect on acne symptoms.

Perhaps the most important role for Alpha Lipoic Acid in relation to acne is its ability to raise Vitamin E levels. Vitamin E helps maintain skin health via its antioxidant properties. Some acne sufferers like to apply Alpha Lipoic Acid as a way of preventing or treating acne scars and others feel that it can reduce the occurrence of acne breakouts. However, neither oral nor topical Alpha Lipoic Acids are likely to dramatically improve acne symptoms for most individuals.

Alpha Lipoic Acid was first discovered in the 1950’s and became a nutritional supplement shortly thereafter. The biologically active form of Alpha Lipoic Acid, RLA, is an essential cellular anti-oxidant. Unlike many other supplements, oral ingestion of RLA rapidly leads to increased levels of bio-available RLA in the blood. While there is not an abundance of research on the role of Alpha Lipoic Acid in the treatment of acne, the research that does exist indicates that Alpha Lipoic Acid may be helpful in decreasing inflammation and improving the immune response to acne. Alpha Lipoic Acid is also available in topical formulations.

Zinc Supplement

Zinc is an essential trace mineral that is required by many human enzymes and cellular processes. Zinc is one of the most common supplements used in the Naturopathic treatment of acne. Both topical and oral Zinc formulations are used as acne treatments. Zinc is one of the most extensively researched nutritional supplements for acne, and their have been several research studies and clinical trials that have reported Zinc supplements to be effective at decreasing the severity of acne symptoms.

Elemental Zinc
Elemental Zinc

Zinc is a popular nutritional supplement is purported to help boost the immune system.  Zinc ions are essential for many key molecular processes, such as gene expression and cellular differentiation. Zinc is one of the primary ingredients in many Naturopathic cold and flu treatments. Zinc deficiency has been shown to suppress the immune system, and several studies have found that important immune functions can be enhanced through regular consumption of Zinc supplements. Although the observed effects of zinc function on the immune system tend to be relatively mild, it is clear that healthy levels of Zinc are important for a healthy immune system.

Relationship of Acne Severity and Blood Levels of Vitamin A, Vitamin E and Zinc (Ozuguz)
Relationship of Acne Severity and Blood Levels of Vitamin A, Vitamin E and Zinc (Ozuguz)

There are several different versions of oral Zinc supplement available, including zinc acetate and zinc gluconate.  A few research studies have found that individuals with moderate to severe acne symptoms tend to have lower levels of Zinc in their blood than individuals without acne symptoms. Because of this relationship, many people believe that Zinc supplements can help improve acne symptoms. In the 1970’s several clinical trials were conducted to investigate whether oral Zinc supplements were effective acne treatments. The results of these trials were mixed, but overall they did tend to find that oral Zinc supplements helped reduce the severity of acne symptoms for some patients.

Zinc can also be used topically as a treatment for acne. Zinc salts can be added to topical Naturopathic anti-acne formulations. Zinc has antimicrobial properties that may help control the growth of acne-causing P. acnes bacteria. Several Zinc acne treatment creams are available, some of which also contain antibiotics. However, most of the clinical research studies on topical Zinc acne treatments have found that they are not very effective.

Overall, oral Zinc supplements are one of the nutritional supplements that is most likely to help improve acne symptoms (according to the available evidence). Zinc supplements are not expected to completely cure acne symptoms for most people. However, they can be combined with many other types of acne treatments. Zinc supplements are generally safe when consumed at recommended dosages, but consuming large quantities of Zinc supplements can be toxic and cause permanent damage.

Vitamin K

Vitamin K Capsules

Vitamin K is a fat soluble dietary nutrient that is essential for the binding of proteins to calcium. Vitamin K deficiencies can lead to bone weakening and blood coagulation problems. Vitamin K is rarely used as a Naturopathic treatment for acne. There is no reliable evidence that indicates Vitamin K supplementation has a significant effect on acne symptoms in otherwise healthy people.

Vegetables are a good source of Vitamin K
Vegetables are a good source of Vitamin K

Vitamin K is generally obtained through the dietary intake of leafy green vegetables. After consumption, bacteria in the digestive tract convert Vitamin K into several structurally similar molecules with important functions. Due to the ability of vitamin K to increase protein binding to calcium, connective tissues in skin may be more flexible and softer with an adequate supply of the vitamin. Because of this effect, some people think that Vitamin K supplements can help improve the appearance of acne scars, but this has not been proven.

Overall, Vitamin K supplements are safe when consumed in recommended concentrations, but are unlikely to be effective treatments for acne.

Vitamin E

Vitamin E Supplements and Acne

Vitamin E is a fat soluble dietary nutrient that is found in many types of plant-based oils, nuts, vegetables and fish. Vitamin E refers to a group of tocopherol and tocotrienol compounds, which have antioxidant properties and are essential for many important biological functions. Vitamin E is one of the most popular vitamin supplements. Vitamin E is widely used as an oral and topical treatment for active acne and acne scars. However, most scientific studies on Vitamin E and acne have found that Vitamin E supplements have little to no effect on acne symptoms.

Almonds are a rich source of Vitamin E
Almonds are a rich source of Vitamin E

Most people who eat a reasonably well-balanced diet do not have a Vitamin E deficiency. Vitamin E is found in fairly high concentrations in nuts and plant-based oils, and it is also added to many processed foods. Vitamin E supplements have been investigated as treatment for a wide range of health problems, from acne to cardiovascular disease. Almost every study conducted has found that Vitamin E supplements do not have significant health benefits for otherwise healthy people. This is most likely because the majority of people already consume abundant amounts of Vitamin E in their diet. In fact, consuming large amounts of Vitamin E supplements can be toxic because excess Vitamin E can not be easily eliminated from the body in the urine.

One of the most common misconceptions about Vitamin E is that topical application of Vitamin E is an can accelerate skin healing and reduce the appearance of acne scars. Many people break open Vitamin E capsules and apply the solution directly to acne scars and other problem areas. Vitamin E is commonly added to moisturizers and other skin creams. However, several clinical research studies have found that topical Vitamin E is not an effective treatment for acne scars. Vitamin E supplements are also an ineffective strategy for decreasing the symptoms of certain acne drugs that can irritate the skin, such as Isotretinoin (Accutane).

Overall, most people have sufficient levels of Vitamin E in their diet and do not significantly benefit from Vitamin E supplements. However, topically application of Vitamin E is safe and has few side effects. Oral Vitamin E supplements are also safe, when consumed in recommended quantities. Vitamin E is an important antioxidant that helps protect cell membranes from oxidative damage. It is possible that Vitamin E may help support healthy skin, but it is unlikely to have a significant effect on active acne symptoms or acne scars.

Vitamin D

Vitamin D and Acne

Vitamin D is a fat soluble vitamin that is important for many biological systems, including the immune system. Vitamin D is not naturally present in many foods, but it is commonly added to certain types of food (eg. Milk, Breakfast Cereal). In humans, Vitamin D is synthesized in the skin when it is exposed to ultraviolet (UV) light from the sun or UV tanning beds. Vitamin D is rarely used as a direct treatment for active acne or acne scars, but it is often incorporated into the dietary component of comprehensive acne treatment plans.

Mushrooms are a rich source of Vitamin D
Mushrooms are a rich source of Vitamin D

Vitamin D is very important in maintaining serum calcium and phosphate levels, which are needed for normal bone mineralization. There are numerous other functions that vitamin D regulates, such as cell growth, neuromuscular and immune function and the reduction of inflammation. However, there is limited evidence that Vitamin D supplementation is beneficial for otherwise healthy people that are do not have a Vitamin D deficiency. Most people obtain significant Vitamin D in their diet, but people living in areas with low levels of sunlight in the winter may benefit from Vitamin D supplements.

Vitamin D3 Solution
Vitamin D3 Solution

Due to the beneficial effects vitamin D has on the immune system, people with acne will benefit from an adequate supply of vitamin D in their diet. Vitamin D may have some anti-inflammatory properties that can help reduce the symptoms associated with acne. However, these effects are likely to be very modest. Vitamin D supplementation is unlikely to dramatically improve acne symptoms for most individuals. There have only been a few clinical research studies on the effectiveness of Vitamin D supplements as treatments for acne. However, some studies from the early 20th century found that Vitamin D supplements were helpful at reducing the number of acne lesions. Overall, more research is needed to understand the relationship between Vitamin D and the development of acne symptoms.

There are a handful of dietary sources of Vitamin D, such as Fish, Mushrooms and Liver. Cod Liver and Fish Oil supplements also contain significant concentrations of Vitamin D.

Vitamin C (Ascorbic Acid) is a water-soluble vitamin that is essential for several biological processes in the human body. Vitamin C is one of the most commonly used nutritional supplements. Vitamin C is an antioxidant and it is added to many products as a preservative. Oral Vitamin C supplements are purported to boost the immune system and high doses of Vitamin C are used in the Naturopathic of many diseases, including acne. Vitamin C is also occasionally added to topical anti-acne formulations.

Citrus is a rich source of Vitamin C
Citrus is a rich source of Vitamin C

One of the most well known diseases related to Vitamin C deficiency is scurvy. Scurvy was once a common affliction of sailors who did not have access to dietary sources of Vitamin C, such as fruits and vegetables. Scurvy is very rare in most populations because a lot of different types of food naturally contain Vitamin C, and many processed foods are supplemented with Vitamin C. Vitamin C deficiencies are rare, but there is some debate as to whether supplementation with high doses of Vitamin C has health benefits.

Vitamin C is essential for the function of the immune system and for wound healing. Vitamin C supplements have been extensively researched for the treatment of many human diseases, especially infections such as the common cold. Overall, these clinical research studies have found that Vitamin C supplements did not significantly reduce symptoms or the duration infection. Many people believe that Vitamin C supplements helped to reduce their acne symptoms. Although there may be some truth to these claims, there does not appear to be any reliable scientific evidence to support them.

Vitamin C Structure
Vitamin C Structure

Because Vitamin C is a water soluble vitamin, excess amounts of this nutrient are readily eliminated from the body in the urine. Therefore, the risk of toxicity due to overdose of Vitamin C is substantially lower than for fat soluble vitamins (eg. Vitamins A, D, E). Vitamin C supplements are considered very safe when used at recommended dosages. Despite the fact that scientific research hasn’t found that Vitamin C improves acne symptoms, Vitamin C supplements may be worth a try for many individuals with acne.
