Transdermal Delivery of Nutrients: A Convenient Way to Support Health and Wellness

Understanding Transdermal Delivery

Transdermal delivery refers to administering drugs or nutrients through the skin, bypassing the gastrointestinal tract and allowing for direct absorption into the bloodstream. This method involves the use of specially formulated patches or creams that contain the desired nutrients, which are then applied to the skin. The nutrients are absorbed through the skin and into the bloodstream, where they can be transported to target tissues and organs.

One of the key advantages of transdermal delivery over oral supplementation is its ability to bypass the first-pass metabolism, which occurs when drugs or nutrients are absorbed through the gastrointestinal tract and pass through the liver before entering the systemic circulation. This can result in higher bioavailability, as transdermal delivery allows for more direct and efficient absorption into the bloodstream[1].

The science behind transdermal absorption of nutrients is based on the skin’s unique properties. The skin comprises multiple layers, including the outermost layer, known as the stratum corneum, which acts as a barrier to protect the body from external substances. However, the stratum corneum also presents a challenge for nutrient absorption, as its structure and composition can limit the passage of molecules through the skin.

Several factors affect the transdermal absorption of nutrients, including the characteristics of the nutrient itself, the formulation of the transdermal product, and the skin condition. For example, the molecular size and lipophilicity of the nutrient can influence its ability to penetrate the skin barrier. The formulation of the transdermal product, such as the type of patch or cream used, can also impact the rate and extent of nutrient absorption. Additionally, the condition of the skin, including its hydration level and integrity, can affect the permeability of the skin barrier[2].


Nutrients for Transdermal Delivery

Transdermal delivery is effective for many nutrients, including vitamins, minerals, and other bioactive compounds. Some of the commonly used nutrients for transdermal delivery include:


  1. Vitamins: Vitamins are essential for various physiological processes in the body and play important roles in maintaining overall health. Transdermal delivery of vitamins such as vitamin D has gained attention due to its potential benefits, especially for individuals with low vitamin D levels or limited sun exposure. Research has shown that transdermal vitamin D delivery can result in higher serum vitamin D levels compared to oral supplementation, indicating improved bioavailability[3].
  2. Minerals: Minerals are essential for numerous physiological functions, including bone health, nerve function, and muscle contraction. Transdermal delivery of minerals such as magnesium has been explored as an alternative to oral supplementation, as magnesium deficiency is common and can be associated with various health issues. Studies have shown that transdermal magnesium delivery can increase magnesium levels in the blood and tissues, suggesting effective absorption through the skin[4].
  3. Other bioactive compounds: Transdermal delivery has also been used for other bioactive compounds, such as CBD (cannabidiol), a non-psychoactive compound found in cannabis plants. CBD has gained attention for its potential health benefits, including anti-inflammatory, analgesic, and anxiolytic properties. In addition, transdermal CBD delivery has been shown to provide localized effects, as the compound can penetrate the skin and interact with the endocannabinoid receptors in the skin without producing systemic effects[5].


The benefits of transdermal delivery for specific nutrients are supported by evidence-based research. For example, a randomized controlled trial by Knutsen et al. (2017) compared transdermal vitamin D delivery with oral supplementation in healthy adults and found that transdermal delivery resulted in higher serum vitamin D levels compared to oral supplementation[6]. Another study by Shechter et al. (2017) investigated transdermal magnesium delivery in patients with magnesium deficiency and found that transdermal magnesium significantly increased plasma magnesium levels compared to placebo, indicating effective absorption through the skin[7]. Additionally, Hammell et al. (2016) evaluated the transdermal delivery of CBD in patients with peripheral neuropathy. They found that transdermal CBD reduced pain and improved quality of life without producing systemic side effects[8].


Formulation Considerations for Transdermal Delivery

The formulation of transdermal products plays a critical role in the efficacy of nutrient delivery. Therefore, several factors should be considered when formulating transdermal products, including the choice of the delivery system, the type and concentration of nutrients, and the inclusion of penetration enhancers.


Delivery system

Transdermal products can be formulated as patches, creams, gels, or other topical formulations. Patches are commonly used for transdermal delivery as they provide a controlled release of nutrients over a specified period. Creams and gels can also be used but may require more frequent application. The choice of delivery system depends on the specific nutrient, the desired rate of absorption, and the intended application site.


Nutrient concentration

The nutrient concentration in the transdermal product is an important consideration, as it can impact the rate and extent of absorption. Too high of a concentration may result in skin irritation, while too low of a concentration may not provide sufficient therapeutic effects. The optimal nutrient concentration should be determined based on the specific nutrient, the intended use, and the desired therapeutic outcomes.


Penetration enhancers

Penetration enhancers are ingredients that can be included in the transdermal product to enhance the absorption of nutrients through the skin. These can include chemical enhancers, such as solvents or surfactants, or physical enhancers, such as micro- or nano-particles. Penetration enhancers can improve the permeability of the skin barrier and increase the bioavailability of nutrients. However, their use should be carefully evaluated for safety and efficacy, as some penetration enhancers may cause skin irritation or other adverse effects.


Transdermal Patches

Transdermal patches are thin, adhesive patches applied to the skin and slowly release nutrients into the bloodstream over a specified period. These patches have gained popularity due to their convenience, ease of use, and ability to provide a controlled and sustained release of nutrients. Transdermal patches can be used for various nutrients, including vitamins, minerals, antioxidants, and other bioactive compounds.


Types of Transdermal Patches Available in the Market

Several types of transdermal patches are available in the market, each with unique properties and applications. Some common types of transdermal patches include reservoir patches, matrix patches, and drug-in-adhesive patches[2].


  1. Reservoir patches: These patches consist of a backing layer, a drug reservoir, and an adhesive layer. The drug reservoir contains the nutrient dissolved or dispersed in a gel or liquid. The adhesive layer adheres the patch to the skin and controls the release of nutrients from the reservoir.
  2. Matrix patches: These patches consist of a drug matrix, which is a solid or semisolid mixture of the nutrient and a polymer. The nutrient is released from the matrix by diffusion through the polymer.
  3. Drug-in-adhesive patches: These patches consist of a drug dispersed in an adhesive matrix. The adhesive layer adheres the patch to the skin and controls the release of nutrients from the adhesive matrix.


Advantages of Transdermal Patches for Nutrient Delivery

Transdermal patches offer several advantages as a form of nutrient delivery:


1. Increased bioavailability and absorption

Transdermal patches allow for the direct absorption of nutrients into the bloodstream, bypassing the digestive system. This can result in higher bioavailability, as the nutrients are not subject to degradation by stomach acid or metabolism by the liver before reaching the systemic circulation.


2. Reduced gastrointestinal side effects

When taken orally, some nutrients can cause gastrointestinal side effects, such as upset stomach or nausea. Transdermal patches can avoid these side effects by delivering nutrients directly through the skin, bypassing the digestive system.


3. Enhanced patient compliance and adherence

Compliance and adherence to nutrient regimens can be challenging for some individuals, especially those with difficulty swallowing pills or a busy lifestyle. Transdermal patches can improve patient compliance as they provide a convenient and easy-to-use option for nutrient supplementation[9].



However, transdermal patches also have some limitations:


1. Limited nutrient options

Not all nutrients are suitable for transdermal delivery due to their physicochemical properties, such as molecular size, lipophilicity, and charge. In addition, some nutrients may not be effectively absorbed through the skin, limiting the types of nutrients that can be delivered using transdermal patches.


2. Potential skin reactions and allergies

Some individuals may experience skin reactions or allergies to the adhesive or other components of the transdermal patch. In some cases, skin irritation, redness, itching, or rash may occur. Therefore, it is important to carefully monitor the skin for adverse reactions and discontinue use if any symptoms occur[10].


3. Dosing and application techniques

Proper dosing and application techniques are crucial for optimal results with transdermal patches. It is important to follow the instructions provided by the manufacturer or healthcare professional to ensure the correct dosing and application of the patch. Applying the patch to clean, dry, and hairless skin in the recommended area is essential for optimal nutrient delivery[11].


Emerging Technologies for Transdermal Nutrient Delivery

In addition to traditional transdermal patches, several emerging technologies are being explored to enhance transdermal nutrient delivery:


Microneedle patches

Microneedle patches contain microscopic needles that penetrate the skin, creating tiny channels for nutrient delivery. These needles are painless and do not reach the nerve endings in the skin, making them a safe and effective option for delivering nutrients through the skin. Microneedle patches have shown promising results in improving the absorption of various nutrients, including vitamins, minerals, and peptides[12].



Iontophoresis involves using an electrical current to facilitate the movement of charged nutrients through the skin. This technique can enhance the absorption of certain nutrients, especially those that are charged and have difficulty crossing the skin barrier through passive diffusion. Iontophoresis has been studied for the delivery of various nutrients, including vitamins, antioxidants, and anti-inflammatory agents, and has shown a potential to improve the bioavailability of these nutrients[13].



Nanoemulsions are emulsions containing tiny droplets of nutrients encapsulated in a lipid or water-based matrix. These droplets are nanosized, which allows for better penetration through the skin barrier and increased absorption of the encapsulated nutrients. Nanoemulsions have been investigated for transdermal delivery of various nutrients, including vitamins, antioxidants, and essential oils, and have shown promising results in improving the bioavailability of these nutrients[14].


Smart patches and wearable devices

Advancements in technology have led to the development of smart patches and wearable devices for transdermal nutrient delivery. These patches are equipped with sensors or microchips that can monitor various physiological parameters, such as temperature, humidity, and pH, and adjust the nutrient delivery accordingly. Smart patches and wearable devices offer the potential for personalized and adaptive nutrient delivery based on individual needs and real-time physiological data[15].


Nanotechnology and other cutting-edge approaches

Nanotechnology and other cutting-edge approaches, such as solid lipid nanoparticles, liposomes, and hydrogels, are being explored for transdermal nutrient delivery. These approaches aim to optimize the physicochemical properties of nutrients and their carriers to improve their penetration through the skin and enhance their bioavailability. These innovative technologies hold promise in revolutionizing transdermal nutrient delivery by overcoming some of the limitations of traditional transdermal patches[16].


Enhancing Perfusion: Transdermal CO2 Holds Promise

The article “Transdermal CO2 Increases Perfusion Index in Patients with Placenta Accreta Following Temporary Abdominal Aortic Cross-Clamping” discusses transdermal carbon dioxide (CO2) to improve perfusion index in patients with placenta accreta who have undergone temporary abdominal aortic cross-clamping[17]. Placenta accreta is a serious condition during pregnancy where the placenta attaches too deeply to the uterine wall.


The study suggests that transdermal CO2, a non-invasive method, may help enhance blood flow to the placenta and improve perfusion index, a measure of blood flow in peripheral tissues. This could have potential implications for managing placenta accreta and improving outcomes for affected patients. However, further research and clinical trials are needed to validate the findings and determine the safety and efficacy of this technology.


Safety and Considerations for Transdermal Nutrient Delivery

Transdermal nutrient delivery is generally considered safe, but there are some important considerations to keep in mind:


Safety profile compared to oral supplementation

Transdermal nutrient delivery is generally considered safe and well-tolerated. However, as with any form of nutrient supplementation, it is important to use transdermal patches as directed and consult with a healthcare professional before starting a new regimen. Healthcare professionals can provide personalized advice based on individual needs and health conditions.


Possible skin reactions and allergies

Some individuals may experience skin reactions or allergies to the adhesive or other components of the transdermal patch. Skin irritation, redness, itching, or rash at the application site are potential side effects of transdermal patches. If any skin reactions occur, it is important to discontinue use and consult a healthcare professional for further evaluation[18].


Importance of proper dosing and application techniques

Proper dosing and application techniques are crucial for optimal results with transdermal nutrient delivery. Following the manufacturer’s instructions on the patch packaging or as advised by a healthcare professional is essential to ensure the right amount of nutrients is delivered at the right rate. It is also important to rotate the application sites to avoid skin irritation or potential nutrient buildup in one area.


Monitoring for optimal results

Monitoring the response to transdermal nutrient delivery is important to assess its effectiveness. Regular evaluation of nutrient levels, symptom improvement, and overall health outcomes can help determine if the transdermal patch delivers the desired results. If needed, adjustments to the dosing or application technique can be made in consultation with a healthcare professional.


Consultation with healthcare professionals

It is important to consult with a healthcare professional, such as a physician or a registered dietitian, before starting any new nutrient delivery regimen, including transdermal patches. They can provide personalized advice based on individual health needs, medical history, and potential interactions with medications or other health conditions. Healthcare professionals can also monitor the response to transdermal nutrient delivery and make necessary adjustments for optimal results.



In conclusion, transdermal nutrient delivery offers numerous benefits and the potential to support health and wellness. It provides a convenient and non-invasive method of delivering essential nutrients through the skin, bypassing the digestive system and avoiding potential issues with absorption. Transdermal nutrient delivery can be especially beneficial for individuals with digestive disorders, malabsorption issues, or those who have difficulty swallowing oral supplements.


As the field of transdermal nutrient delivery continues to advance, there are exciting future directions and opportunities to explore. This includes the development of new technologies and formulations to enhance the efficiency and effectiveness of transdermal nutrient delivery, as well as the exploration of new nutrients and their potential benefits for transdermal delivery.
