Nicotinamide Benefits and Side Effects FAQ
What are the Potential Benefits of Nicotinamide for the Body
Skin Health
Nicotinamide offers several health benefits for the body, particularly in skin health:
- Keratin Production: It helps build keratin, a protein essential for maintaining firm and healthy skin.
- Moisture Retention: Enhances the skin's lipid barrier, locking in moisture and keeping pollutants out.
- Reduces Redness: Nicotinamide may reduce redness and is beneficial in treating skin conditions such as acne and rosacea.
- Anti-Aging Effects: It has the potential to help with wrinkles and other signs of aging skin.
Disease Prevention and Treatment
Nicotinamide has also been studied for potential benefits in managing and preventing various health issues:
- Diabetes and Chronic Kidney Disease: It has shown potential in treating diabetes and reducing blood levels of phosphate in people receiving dialysis for chronic kidney disease.
- Type 1 Diabetes Prevention: Studies have investigated its use in delaying the development of type 1 diabetes in high-risk individuals.
- Pellagra Treatment: Nicotinamide supplementation can reverse symptoms of pellagra, a condition characterized by mouth inflammation, upset stomach, and skin issues.
Skin Cancer Prevention
- Reduced Risk: Studies indicate that oral nicotinamide can reduce the risk of developing new non-melanoma skin cancers, squamous-cell carcinomas, and actinic keratosis.
Central Nervous System Health
- Neuronal Health: Research has shown potential in improving neuronal health within the central nervous system.
It's important to consult a healthcare provider before starting any supplement regimen to ensure that nicotinamide is used safely and effectively based on individual health needs.

Can nicotinamide help with other skin conditions aside from acne and rosacea?
Yes, nicotinamide has shown promise in treating a variety of skin conditions beyond acne and rosacea. It is a form of vitamin B-3 that possesses a multitude of skin benefits, due to its anti-inflammatory properties and ability to help build proteins in the skin and lock in moisture to prevent damage from external factors. These properties make it beneficial for several skin concerns.
-
Prevention of Skin Cancers: Nicotinamide has been studied for its potential to prevent common types of skin cancers, including squamous-cell and basal-cell carcinoma. A notable study revealed that oral supplementation of nicotinamide reduced the rate of new squamous-cell and basal-cell skin cancers by 23% compared to a placebo after one year among high-risk individuals 1.
-
Treatment of Autoimmune Blistering Diseases: Nicotinamide has been used for the treatment of bullous (blistering) diseases, thanks to its anti-inflammatory action. An oral combination of nicotinamide and tetracycline has provided an alternative treatment to systemic steroids for bullous pemphigoid, showing promising results in clinical trials 3.
-
Improvement of Aging Skin: Nicotinamide is reported to improve the complexion, pigmentation, redness, and signs of aging in the skin. It has been incorporated into cosmeceutical products aimed at reducing the appearance of fine lines, wrinkles, and improving skin hydration by strengthening the skin's barrier function 3.
-
Prevention of Actinic Keratoses: Research suggests that nicotinamide may reduce actinic keratoses, which are precancerous skin lesions caused by sun damage. This is particularly beneficial for individuals with extensive sun damage who are at high risk for squamous cell carcinoma 3.
-
Treatment of Polymorphic Light Eruption: Nicotinamide has shown benefits in treating polymorphic light eruption, a condition characterized by a delayed allergic reaction to sunlight, resulting in rashes or blistering on exposed skin 3.
The amassed evidence suggests that nicotinamide's range of benefits for the skin is broad, encompassing not only common conditions like acne and rosacea but also offering protective properties against skin cancer, improving the appearance and health of aging skin, and treating specific sun-related skin conditions. However, while promising, it's important to note that ongoing research is crucial to fully understand nicotinamide's capabilities and mechanisms of action in these diverse dermatological applications.
What are the Potential Side Effects of Oral Nicotinamide
When taken orally at high doses (3000mg+ per day), nicotinamide can cause several side effects, although it is generally considered safe when used in recommended amounts. Here are some potential side effects associated with high doses of nicotinamide:
-
Liver Toxicity: High doses of nicotinamide have been linked to liver toxicity in some cases. This is one of the more serious side effects and can manifest as elevated liver enzymes, jaundice, or more severe liver damage.
-
Gastrointestinal Issues: Some people may experience gastrointestinal problems, such as nausea, vomiting, diarrhea, and stomach discomfort when taking high doses of nicotinamide.
-
Skin Reactions: Although nicotinamide is often used for its skin benefits, high doses can sometimes cause adverse skin reactions like flushing, itching, or rash.
-
Blood Sugar Fluctuations: There is some evidence to suggest that high doses of nicotinamide can affect blood sugar levels, potentially causing fluctuations that could be concerning for individuals with diabetes or those at risk of diabetes.
-
Eye Issues: High doses of nicotinamide have been associated with vision problems, such as blurred vision, although this is relatively rare.
-
Dizziness and Headaches: Some individuals may experience dizziness and headaches as a side effect of high doses of nicotinamide.
How does these side effects compare to Nicotine?
What are the potential side effects of nicotine
Nicotine, a highly addictive substance found in tobacco products, has a wide range of potential side effects that can impact various systems throughout the human body. When nicotine enters the body, it's quickly absorbed into the bloodstream, reaching the brain and leading to the release of dopamine, which creates feelings of pleasure and reward. This mechanism can lead to a cycle of dependency as the pleasurable sensations are short-lived, prompting continued use to maintain them 1.
In terms of cognition, nicotine may temporarily improve concentration and memory, but its long-term use is associated with a decline in cognitive ability and an increased risk of Alzheimer’s disease 1. Despite the short-term cognitive boost, the long-term cognitive risks and other physical side effects underscore nicotine's harmful impact.
Physical side effects of nicotine use include dizziness, lightheadedness, sleep disturbances, changes in blood flow, headaches, increased risk of blood clotting, changes in heart rhythm, increased blood pressure, and gastrointestinal issues such as peptic ulcers and heartburn 1. Additionally, it can cause symptoms specific to different nicotine products, like skin irritation, nausea, and aching muscles from use of patches, gums, and other nicotine replacement therapies (NRTs) 1.
Nicotine also adversely affects various bodily systems, with serious consequences. For the cardiovascular system, nicotine is partly to blame for atherosclerosis, heart rate fluctuations, increased blood pressure, coronary artery disease, and various arrhythmias 2. The respiratory system can suffer from shortness of breath, chronic obstructive pulmonary disease (COPD), and an increased risk of developing cancer 2. The gastrointestinal system may experience peptic ulcers, diarrhea, nausea, and increased risks of cancer 2.
Furthermore, nicotine withdrawal can pose additional challenges for individuals trying to quit, including anxiety, depression, sleep troubles, increased appetite, headaches, and concentration issues. These symptoms highlight the physical dependence developed on nicotine due to its addiction properties 2.
In conclusion, nicotine affects nearly every system in the body and can lead to a wide array of negative health effects, ranging from immediate symptoms like dizziness and nausea to long-term risks like cardiovascular disease and cognitive decline. As such, understanding these potential side effects is crucial for anyone considering using nicotine products or looking to quit.
