FAQ

What is Vitamin D?

Vitamin D is fat-soluble vitamin that is essential for key processes in the body including immune health, musculoskeletal health and bone strength. It is both a nutrient that we can ingest, and a hormone that our body creates when triggered by the sun’s UVB rays.

What is vitamin D and why is it important for our health?

According to the WHO (World Health Organisation), approximately 1 billion people worldwide are vitamin D deficient. Vitamin D is essential for our general health and wellbeing.

Vitamin D exists in our bodies as a hormone. It aids in regulating calcium and phosphorus absorption, which are crucial for maintaining healthy bones and teeth. Vitamin D supports cardiovascular health, muscles and nerves. It promotes proper cell division in the body, supports a healthy immune system and can help regulate mood.

What is liposomal vitamin D, and how is it different from regular vitamin D supplements?

Soma Vitamins Liposomal Vitamin D is a specialised type of formulation that uses liposomes, which are tiny phospholipid spheres. The vitamin D molecules are enclosed in these liposomes. These liposomes serve as protective carriers and improve absorption and distribution to your body’s cells. On the other hand, regular vitamin D supplements are often non liposomal liquid drops, tablets, or capsules that may not be as optimally absorbed by the body.

What’s the difference between Vitamin D, Vitamin D2 and vitamin D3?

Vitamin D is a group of fat-soluble compounds that are important for various functions in the body. There are two main forms of vitamin D: vitamin D2 (Ergocalciferol) and vitamin D3 (Colecalciferol).

The main difference between vitamin D2 and vitamin D3 lies in their sources. Vitamin D2 is primarily derived from plant sources, such as mushrooms exposed to ultraviolet (UV) light. On the other hand, vitamin D3 is synthesised in the skin when it is exposed to sunlight, and it is also found in certain animal-based food sources like fatty fish, egg yolks, and liver.

While both vitamin D2 and vitamin D3 can raise the levels of vitamin D in the body, studies have shown that vitamin D3 is more effective in increasing and maintaining vitamin D levels. Vitamin D3 is considered the more biologically active form of vitamin D. It has a longer half-life and is better utilised by the body compared to vitamin D2. When it comes to supplementation, most over-the-counter vitamin D supplements contain vitamin D3, as it is the preferred form for maintaining optimal vitamin D levels. However, in some cases, vitamin D2 may be prescribed by healthcare professionals for specific medical conditions.

In summary, the main difference between vitamin D and vitamin D3 is their source. Vitamin D3 is the more effective and biologically active form, commonly obtained from sunlight and certain animal-based food sources.

Can’t I just get Vitamin D from the sun?

In order for your body to produce an active form of vitamin D, it is necessary to be exposed to sunlight. However, it’s important to note that your body can only generate a specific amount of vitamin D during each exposure. Therefore, spending excessive time in the sun will not result in increased vitamin D production but will instead elevate the risk of skin cancer.

Can my vitamin D levels change with the seasons?

Yes, vitamin D levels in the body can vary with the seasons. To obtain optimum vitamin D levels throughout the year, it is important to consider dietary or supplementary sources. The primary source of vitamin D for most people is sunlight exposure, specifically through the skin’s interaction with ultraviolet B (UVB) rays.

During the summer months when sunlight is stronger and people tend to spend more time outdoors, vitamin D synthesis in the skin is typically more efficient, resulting in higher levels of vitamin D in the body. In contrast, during the winter months when sunlight is weaker and people spend more time indoors, vitamin D synthesis is reduced, leading to lower levels of vitamin D.

The seasonal variation in vitamin D levels can be particularly pronounced in regions farther from the equator, where the angle of the sun changes significantly throughout the year. In these areas, there may be a greater likelihood of vitamin D deficiency during the winter months.

What does bioavailability in pharmacology mean?

Bioavailability, when referring to a vitamin or nutrient, is a measure of how effectively and efficiently your body can absorb and utilise that substance. In other words, it determines the amount of the vitamin or nutrient that is actually available for your body to use after consumption.

When you consume a vitamin or nutrient through food or supplements, it needs to be broken down and absorbed into your bloodstream to be transported to the cells and tissues where it’s needed. However, not all of the vitamins and nutrients that you consume are necessarily absorbed and used by your body in the same way.

Bioavailability takes into account factors such as the form of the nutrient, how it’s prepared or processed, and its interactions with other substances in your body. It can vary between different vitamins, nutrients, and even different forms of the same nutrient.

A high bioavailability means that a larger proportion of the vitamin or nutrient you consume is absorbed and made available for your body to use. On the other hand, a low bioavailability indicates that a smaller amount is absorbed, and therefore, you may need to consume higher doses to achieve the desired effect.

Improving bioavailability can be important because it ensures that your body receives an adequate amount of the vitamin or nutrient to support its functions and overall health. Different factors, such as the presence of certain foods or substances, can enhance or hinder the bioavailability of a particular nutrient.

Understanding the bioavailability of a vitamin or nutrient helps to determine the most effective ways to consume and supplement it, ensuring that you’re receiving the maximum benefits from what you consume.

Remember to always read the label of any of your vitamins/medications, not exceed the recommended dosage, and consult with your GP when incorporating any new vitamins, supplements or medications in your routine.

How does liposomal vitamin D enhance absorption and bioavailability?

Liposomal technology enhances the absorption and bioavailability of vitamin D by encapsulating the nutrient within fat-soluble spheres called liposomes. These liposomes protect the vitamin D from early degradation in the digestive system and facilitate its transport across cell membranes.

As a result, liposomal vitamin D has the potential to deliver higher concentrations of the nutrient to the cells, allowing for increased bioavailability, absorption and utilisation by the body.

What specific medical conditions can liposomal Vitamin D help with?

Aside from general health and wellbeing, liposomal vitamin D can be beneficial for various medical conditions and symptoms related to vitamin D deficiency or insufficiency.

Vitamin D is essential for the proper functioning of the body, and its deficiency can lead to several health issues.

Here are some conditions or symptoms that liposomal vitamin D may help with. Please remember, the information below is by no means an exhaustive or definitive list, and is intended for information purposes only. For more tailored and specific advice we advise you discuss such considerations with your General Practitioner (GP).

  1. Vitamin D deficiency: Liposomal vitamin D is commonly used to treat and prevent vitamin D deficiency, which can occur due to inadequate sun exposure, limited dietary intake, malabsorption conditions, or certain medications. Vitamin D deficiency can cause symptoms like bone pain, muscle weakness, fatigue, and increased susceptibility to infections.
  2. Osteoporosis and Osteopenia: Vitamin D plays a crucial role in calcium absorption and bone health. Supplementation with liposomal vitamin D may be recommended for individuals with Osteoporosis (reduced bone mineral density) or Osteopenia (lower than normal bone density) to support bone strength and help reduce the risk of fractures.
  3. Immune system support: Vitamin D has immune-modulating effects and is important for optimal immune system function. Adequate vitamin D levels may help reduce the risk and severity of respiratory tract infections, autoimmune diseases, and certain allergic conditions.
  4. Muscle function: Vitamin D is involved in muscle function and may help improve muscle strength and performance. It can be beneficial for individuals with muscle weakness or conditions like Sarcopenia (age-related muscle loss) or certain neuromuscular disorders.
  5. Mood disorders: Some research suggests a potential link between low vitamin D levels and mood disorders like depression and seasonal affective disorder (SAD). While the evidence is not conclusive and more research needs to be performed, supplementation with liposomal vitamin D may be useful as part of a comprehensive treatment approach for individuals with these conditions. Discuss this with your GP to find out more.
  6. Cardiovascular health: There is an emerging body of evidence in the scientific literature suggesting that vitamin D may play a role in maintaining cardiovascular health. Some studies suggest that vitamin D deficiency is associated with an increased risk of cardiovascular diseases. Liposomal vitamin D supplementation may help support cardiovascular health, although more research is needed in this area. Remember, cardiovascular health and managing cardiovascular disease is a complex and specialised area of medicine which requires a multidisciplinary team approach. Please discuss with your GP regarding matters relating to your overall cardiovascular health.

I heard that Vitamin D can help protect against COVID-19. Is this true?

Vitamin D and its possible protective effect against COVID-19 is an area of research that is still evolving. However it is worth noting that adequate vitamin D levels are important for overall immune function and respiratory health. Some studies have suggested a potential association between Vitamin D deficiency and an increased risk of respiratory infections including viral infections like influenza.

A recent systematic review from June 2022 (Taja Jordan, Darko Siuka, Nada Kozjek Rotovnik and Marija Pfeifer) has suggested that Vitamin D supplementation may play an important role in protecting from acute respiratory infections like the SARS CoV2, and in high-risk individuals with COVID 19 from progressing to critical clinical condition and reducing mortality.

Another systematic review and meta-analysis of randomised control trials (RCTs) published in 2022 by Seshadri Reddy Varikasuvu, Balachandar ThangappazhamAlekya Vykunta, Pragathi Duggina, Munikumar Manne, Hemanth Raj, and Sowjanya Aloori) explored the association between vitamin D levels and the susceptibility, severity, ICU-care, and mortality events of Covid-19. The meta-analysis of the RCTs showed that Covid-19 patients supplemented with vitamin D had overall reduced risk of COVID-19 susceptibility and severity outcomes, but showed no significant difference for the “relative risk of ICU-admission and mortality outcomes upon vitamin D supplementation.” This meta-analysis included a total of 6 RCTs involving 551 Covid-19 patients. However, the results of this study strongly suggest the need for future and ongoing RCTs. Further testing will need to consider better designs to further assess the relationship and effect of vitamin D supplementation on an individual with Covid-19.

These designs would ideally need larger sample sizes and to control for confounding variables e.g. weight, BMI, age and other medical conditions.

Additionally it is important to mention that these studies do not focus on liposomal vitamin D specifically. The potential benefits of vitamin D supplementation in general, including liposomal formulations for COVID-19 prevention or treatment still needs investigation. More research, including high level clinical trials, is needed to establish a clear link between vitamin D supplementation and COVID-19 outcomes.

In matters relating to COVID-19 it is advisable to follow the latest guidelines and updates provided by the Australian Department of Health at https://www.health.gov.au/health-alerts/covid-19 and consult with your GP.

Your GP will consider your medical history, current health status, and the most up-to-date scientific evidence available.

Can vitamin D help with depression/other mood disorders?

Vitamin D plays a crucial role in many bodily functions, including brain health and mood regulation. Adequate vitamin D levels have been associated with better overall mental health, and some studies have suggested a potential link between vitamin D deficiency and increased risk for depression and mood disorders.

Studies looking specifically at liposomal vitamin D is still limited and is an area that requires more high level research. It is also important to note that vitamin D supplementation alone is not a substitute for proper diagnosis and treatment of depression or mood disorders. These conditions are complex and multifactorial and require a comprehensive approach that may include cognitive behavioural therapy, lifestyle modification and medications that can only be prescribed from specialist medical practitioners, such as psychiatrists.

We advise that you speak to your GP if you’re experiencing changes to your mood or mental health. In a medical emergency or if you or someone you know is experiencing a mental health crisis you must call an emergency ambulance service for your area.

Alternatively here are reputable Australian websites that provide valuable resources for people suffering from mental illness; remember they are not a substitute for seeking professional help and function more as a source of information and support.

I heard that Vitamin D can help with ADHD (Attention-Deficit/Hyperactivity Disorder). Is this true?

Vitamin D has been investigated in relation to ADHD but the evidence regarding its effectiveness is currently limited and requires more research and analysis. Some studies have found an association between low vitamin D levels and ADHD symptoms, suggesting a potential link. However it is unclear whether this association indicates a causative relationship or if its simply correlation.

Some studies found modest improvements in ADHD symptoms with vitamin D supplementation, while other studies found no significant benefits. The review concluded that further well designed clinical trials are needed to determine the effectiveness of Vitamin D supplementation and its potential therapeutic role relating to ADHD symptoms.

Importantly, ADHD is a complex neurodevelopmental condition, and typically involves a multidisciplinary approach that may include behavioural interventions, therapy and in some cases medications.

While vitamin D levels are important for overall health, it should not be considered a standalone treatment for ADHD.

If you, or someone you know is experiencing symptoms of ADHD, it’s important to consult with a healthcare professional such as a GP, a psychiatrist or pediatrician with a special interest in ADHD. These professionals can provide a comprehensive evaluation and diagnosis and recommend an appropriate treatment plan tailored to the individual’s specific needs.

Is there a correlation between Vitamin D being protective against bowel cancer?

Research has suggested a potential link between vitamin D and bowel (colorectal) cancer, although the relationship is complex and not fully understood. Some studies have indicated that higher levels of vitamin D may be associated with a reduced risk of developing colorectal cancer, while vitamin D deficiency has been linked to an increased risk.

However, more research is needed to establish a definitive cause-and-effect relationship and understand the underlying mechanisms. Vitamin D plays a crucial role in various processes within the body, including cell growth regulation, immune function, and inflammation modulation. These mechanisms are relevant to the development and progression of cancer.

Vitamin D receptors are found in cells of the colon and rectum, and it is believed that vitamin D may influence the growth and differentiation of these cells, potentially impacting the risk of colorectal cancer.

Some studies have suggested that adequate vitamin D levels may help inhibit the growth of colorectal cancer cells, promote apoptosis (programmed cell death) of cancer cells, and reduce inflammation in the colon. However, it is important to note that the evidence in this area is not yet conclusive, and additional research is needed to fully understand the relationship between vitamin D and colorectal cancer.

While maintaining optimal vitamin D levels through sunlight exposure, dietary sources, or supplementation is generally recommended for overall health, it is essential to consult with a healthcare professional for personalised advice and guidance on any specific health concerns, including colorectal cancer. They can consider your individual risk factors, medical history, and the latest scientific evidence to provide appropriate recommendations.

Importantly, if you are due for any routine testing or have any symptoms or predispositions to colorectal cancer, you should consult with your GP immediately to organise appropriate testing and review.

In Australia, people with an average population baseline risk of bowel cancer, must perform faecal occult blood test (FOBT) every 2 years from the age of 50 to 74. Individuals with a higher risk of developing bowel cancer will need to start investigations sooner, sometimes in their 30s.

Please talk to your GP about assessing your bowel cancer risk (low, medium or high) and the screening and diagnostic tests that are available. For more reading on bowel cancer you may visit: bowelcanceraustralia.org/screening

I’ve heard that vitamin D can help with rhinosinusitis or nasal polyps. Is this true?

Vitamin D supplementation may have potential benefits for nasal polyps and rhinosinusitis, but further research is needed to establish its efficacy and optimal use in these conditions.

Some studies suggest that vitamin D deficiency may be associated with an increased risk of developing chronic rhinosinusitis and nasal polyps. Vitamin D has known immunomodulatory effects and plays a role in reducing inflammation. Therefore, it is theorised that maintaining adequate vitamin D levels may help support the immune system and potentially alleviate symptoms in some individuals.

However, the available evidence is still limited, and more high-quality studies are needed to determine the effectiveness of vitamin D supplementation in treating or preventing nasal polyps and rhinosinusitis specifically.

If you are considering vitamin D supplementation for these conditions, it is important to consult with your GP or Ortolaryngologist (Ear, Nose Throat specialist) who can assess your individual circumstances and provide personalized advice. They can consider factors such as your vitamin D levels, overall health, and other treatments you may be receiving to determine the most appropriate course of action for you.

Is liposomal vitamin D suitable for everyone? Can it interact with any of my other medications?

Soma Liposomal Vitamin D is not recommended for people under the age of 18 or those pregnant/breastfeeding.

The majority of people, including those who have trouble absorbing nutrients through conventional methods, may benefit from liposomal vitamin D. Prior to beginning any new supplement regimen, it is, recommended that you seek medical advice, especially if you have any pre-existing medical concerns or are taking drugs that may interact with vitamin D. Your Doctor can provide personalised guidance on potential interactions and help you determine the best approach for incorporating liposomal vitamin D into your regimen.

Some potential interactions to consider include:

  1. Medications that increase calcium levels: Vitamin D helps with calcium absorption, so taking liposomal vitamin D along with medications that increase calcium levels, such as thiazide diuretics (e.g., hydrochlorothiazide), may lead to high calcium levels (hypercalcemia).
  2. Certain anticonvulsant medications: Some anticonvulsant medications, such as phenytoin and phenobarbital, may increase the breakdown of vitamin D in the body, potentially reducing its effectiveness.
  3. Corticosteroids: Long-term use of corticosteroids, such as prednisone or cortisone, may decrease the absorption and metabolism of vitamin D, leading to lower levels of the vitamin in the body.
  4. Orlistat: Orlistat is a weight loss medication that may interfere with the absorption of fat-soluble vitamins, including vitamin D. Taking liposomal vitamin D and orlistat together may reduce the absorption of vitamin D.
  5. Mineral oil: Mineral oil, when taken internally, can reduce the absorption of fat-soluble vitamins, including vitamin D. If liposomal vitamin D is taken along with mineral oil, it may interfere with the absorption of the vitamin.

It is important to note that these interactions may not occur in all individuals, and the significance of interactions can vary depending on the specific medication, dosage, and individual factors.

It is always recommended to consult with your GP or pharmacist before starting any new medications or supplements, including liposomal vitamin D, especially if you are taking other medications. They can provide personalised advice based on your specific situation.
