In the UK, it is recommended that both males and females over the age of 1 consume 10 micrograms (400UI) of vitamin D per day. For adults, doctors often suggest taking a 1000IU vitamin D supplement, which can be easily found in health food stores and pharmacies. This is especially important as many people we test are found to be deficient in vitamin D. It is advised to monitor your vitamin D levels regularly.

Excellent sources of vitamin D can be found in foods such as oily fish (like salmon, herring, and mackerel), red meat, liver (though pregnant individuals should avoid this), egg yolks, and fortified foods like fat spreads and breakfast cereals. Another option for getting enough vitamin D is through dietary supplements. However, it's important to note that in the UK, cows' milk is not typically fortified with vitamin D like it is in some other countries. Excellent sources of vitamin D can be found in foods such as oily fish (like salmon, herring, and mackerel), red meat, liver (though pregnant individuals should avoid this), egg yolks, and fortified foods like fat spreads and breakfast cereals.

The symptoms of vitamin D deficiency can present in a variety of ways. These may include fatigue, increased aches and pains, seasonal depression, sadness and a higher susceptibility to illnesses. It is important to note that even without obvious symptoms, it is still recommended to test your vitamin D levels, as many adults in the UK are deficient or do not have sufficient levels. If your test results indicate a deficiency, we will provide you with recommendations on how you can improve your vitamin D levels.

Different laboratories have varying normal ranges for vitamin D levels in the blood, but in general, a level below 50nmol/L is seen as insufficient. There is no consensus on the optimal vitamin D level, with some sources suggesting it may be as high as 70-80nmol/L. Here is a general guide based on figures from NICE guidance and other sources: - <25 nmol/L: Deficient - 25-50 nmol/L: Insufficient - >50 nmol/L: Adequate - >125 nmol/L: Too high

Not getting enough vitamin D can lead to weaker bones, increased risk of diseases such as osteomalacia and rickets, a compromised immune system, and a higher likelihood of developing certain types of cancers, depression, sadness, heart disease, and obesity.

1. Fatigue and tiredness 2. Bone and back pain 3. Hair loss 4. Muscle pain and weakness 5. Depression 6. Impaired wound healing 7. Constant illness or infections 8. Slow healing of fractures 9. Impaired cognitive function 10. Reduced bone density and increased risk of fractures.

The most precise method of measuring your vitamin D level is through the Vitamin D (25 OH) Blood Test. You have the option to conveniently test your vitamin D level at home using our simple finger-prick blood test kit, or have your blood sample collected at home at your convenience.

The recommended daily intake of vitamin B12 varies depending on factors such as age, sex, and specific health conditions. Here are the general guidelines for daily intake: For adults (age 19 years and older), the recommended daily intake is 2.4 micrograms (mcg) of vitamin B12. Pregnant women should aim for 2.6 mcg per day. Breastfeeding women need slightly more, with a recommended intake of 2.8 mcg per day. Vitamin B12 requirements may be higher for individuals with certain medical conditions, such as pernicious anemia or gastrointestinal disorders that affect absorption.

Some sources of B12 include meat, poultry, fish, eggs, and dairy products. Additionally, certain foods like cereals are fortified with B12.

Vitamin B12 or folate deficiency anaemia can cause a wide range of symptoms. These usually develop gradually, but can worsen if the condition goes untreated. Most symptoms are the same whether they are caused by either folate deficiency or vitamin B12 deficiency. Symptoms of vitamin B12 and folate deficiency anaemia include: rapid breathing or shortness of breath headaches indigestion loss of appetite palpitations problems with your vision feeling weak or tired diarrhoea a sore or red tongue, sometimes with mouth ulcers problems with memory, understanding and judgment (cognitive changes) Some of these symptoms can also happen in people who have a vitamin B12 or folate deficiency but have not developed anaemia. Vitamin B12 deficiency can also cause symptoms that affect your brain and nervous system (neurological symptoms), including: numbness muscle weakness psychological problems, which can range from mild depression or anxiety, to confusion and dementia problems with balance and coordination pins and needles incontinence

The normal range for vitamin B12 can vary slightly depending on the lab. But a normal level of vitamin B12 in your bloodstream is generally between 190 and 950 picograms per milliliter (pg/mL). Between 200 to 300 pg/mL is considered borderline and your doctor may do more testing.

A deficiency in vitamin B12 can result in enduring harm to the brain and nervous system, contributing to feelings of fatigue, weakness, and dizziness, as well as a general sense of mental unease.

Generally, conventional guidance deems a ferritin level under 20ug/L as abnormally low, we advocate for surpassing the conventional 'normal' range to promote peak health. Numerous specialists, including dermatologists, sleep consultants, and sports medicine doctors, advise aiming for a ferritin level around 100ug/L for optimal performance. This elevated level guarantees ample iron supply for the intricate biological processes crucial across various bodily systems.

Increasing ferritin levels can be accomplished by making changes to your diet and taking supplements. It's essential to include iron-rich foods such as red meat and leafy green vegetables in your meals. Moreover, it's advisable to take a daily iron supplement. To enhance absorption, take the supplement with citrus fruit juice on an empty stomach.

Reducing elevated ferritin levels starts with identifying the underlying cause. It's crucial to pinpoint why your ferritin levels are high to implement appropriate measures. Lifestyle adjustments such as dietary changes and moderating alcohol intake might be necessary.

There are two main types of dietary iron: heme iron, present in animal products, and non-heme iron, found in plant-based and fortified foods. Heme iron sources include red meat, poultry, and fish. Non-heme iron sources encompass legumes, beans, fortified foods, and leafy green vegetables. Here's a list of ten foods rich in iron: 1. Red meat (beef, lamb, pork) 2. Liver (especially beef liver) 3. Poultry (chicken, turkey) 4. Fish (such as tuna, salmon, and sardines) 5. Shellfish (like oysters, clams, and mussels) 6. Beans (such as chickpeas, lentils, and black beans) 7. Tofu 8. Quinoa 9. Spinach 10. Fortified breakfast cereals

As per UK government guidelines, adult males should aim for 4.7mg of iron daily, while adult females should target 8mg [1]. However, women experiencing heavier menstrual periods might require additional iron. The maximum absorbable amount is approximately 60mg of elemental iron per day, beyond which Hepcidin inhibits iron transport across the gut wall. Department of Health: Dietary Reference Guidelines

Ferritin is a protein housing iron and serves as the main storage form of iron within cells. Generally, it serves as a reliable indicator of overall iron levels in the body. Iron plays crucial roles beyond just red blood cell production; it's involved in various functions including sleep quality, immune response, and even thyroid function, potentially offering benefits with increased levels. During heightened activation of white blood cells, ferritin may be released into the bloodstream, making it a commonly used surrogate marker for inflammation.

Folate, also known as folic acid or vitamin B9, plays several important roles in the body, including in making DNA, which is your unique genetic code. An inadequate level of folate in the body, called folate deficiency, can lead to Anemia and other changes to your health. Anemia may cause symptoms like weakness, shortness of breath, and mental changes.

The thyroid is a gland located in your neck responsible for producing hormones called thyroxine (T4) and triiodothyronine (T3). These hormones play a vital role in regulating the activity of cells and tissues throughout the body. T3 serves as the active hormone, formed by the conversion of T4 within the body. It governs metabolism, dictating the pace at which cells function. The pituitary gland regulates the production of thyroid hormones by releasing thyroid stimulating hormone (TSH) to stimulate the thyroid gland.

Our thyroid check is suitable for individuals seeking to assess whether symptoms such as abrupt weight changes, mood fluctuations, sleep disturbances, or muscle weakness may stem from a thyroid-related concern. Additionally, it proves valuable for monitoring an ongoing thyroid condition.

Early signs of thyroid problems may encompass: Sensitivity to cold or heat Changes in weight (either gain or loss) Constipation Low mood Muscle weakness and aches Reduced libido Mood swings Sleep disturbances

The primary cause of an overactive thyroid (hyperthyroidism) is often Graves' Disease, an autoimmune disorder characterized by the release of antibodies prompting excessive production of thyroid hormone. Other less frequent causes include thyroid nodules and medications that elevate iodine levels in the body.

Typically, an underactive thyroid (hypothyroidism) arises when the immune system mistakenly attacks and damages the thyroid gland, impairing its capacity to generate an adequate amount of hormones.

Upon receiving a thyroid condition diagnosis, it's common to seek lifestyle improvements to alleviate symptoms, complement prescribed medication, or strive for a return to normalcy. Evaluating our dietary choices and considering supplements is a natural initial step in this process.

A cortisol blood test measures the cortisol levels in your bloodstream, serving as an indicator of stress. Assessing stress levels can offer insights into factors contributing to fatigue, poor sleep quality, or mood fluctuations.

Your cortisol levels rise and fall throughout the day, but are highest in the morning, when you wake up, so it’s best to collect your blood sample before 10am or within 3 hours of waking up. Our cortisol blood test kit has everything you need to collect a blood sample at home, including free return postage to our labs. Our doctors will review your results to provide feedback on your levels and advice on how to improve them.

Persistent high levels of cortisol can negatively impact health. Symptoms of heightened cortisol include: Weight gain Feeling confused Unable to focus Muscle weakness Alterations in skin condition Hypertension (high blood pressure) Irregular or absent menstrual periods Increased thirst and urination Fatigue Mood fluctuations Sleep disturbances Cognitive difficulties Decreased libido

Cortisol is a steroid hormone produced by the adrenal glands. Abnormal cortisol levels can lead to health conditions. Cortisol impacts: effective metabolism of glucose blood pressure inflammation reduction your response to dangers

Implementing lifestyle adjustments can effectively manage cortisol levels. Dietary modifications, regular exercise, and stress-relieving activities all contribute to lowering stress and cortisol levels. Participating in Mindfulness-Based Stress Reduction Programs can enhance stress management skills. Additionally, activities like yoga, Pilates, and meditation may offer benefits. Whenever possible, distancing oneself from stressful situations can also be helpful.

The typical range for cortisol levels is between 160 – 600 nmol/L.

High cortisol levels can be triggered by various factors: Stress: Cortisol, often termed the "stress hormone," is produced in response to stressors. Chronic stress can lead to persistently elevated cortisol levels. Intense Physical Activity: High training loads in athletes can stimulate cortisol production due to the physical stress exerted on the body during workouts. Medical Conditions: Certain medical conditions, such as Cushing's syndrome, pituitary gland disorders, or adrenal gland disorders, can cause elevated cortisol levels. Medications: Some medications, including corticosteroids used to treat inflammatory conditions, can lead to increased cortisol levels as a side effect. Poor Sleep: Inadequate or disrupted sleep patterns can elevate cortisol levels, as sleep plays a crucial role in regulating cortisol secretion. Diet: Consuming excessive amounts of caffeine or refined sugars, or following a high-stress diet, can contribute to elevated cortisol levels.

One study found that, compared to running, swimming was more effective in reducing cortisol. Submerging your whole body in water can also be therapeutic – the repetition of a swimming stroke gives you something to focus your mind on.

Did you know that an estimated 850,000 people may be living with undiagnosed diabetes? This staggering figure highlights the importance of raising awareness about the signs and symptoms of diabetes, as early detection and management are crucial for preventing complications and improving overall health outcomes. By increasing public education and promoting regular health screenings, we can strive towards ensuring that everyone has access to timely diagnosis and appropriate treatment for diabetes."

If you have concerns that your lifestyle habits may increase your risk of developing type 2 diabetes, it's advisable to take this test. Additionally, individuals with type 2 diabetes who wish to monitor their condition can benefit from this test. Regular screenings can help identify pre-diabetes or diabetes early, enabling prompt intervention and management to prevent complications and maintain overall health.

Our HbA1c test offers the convenience of testing for diabetes from the comfort of your home using a simple finger-prick method. The test kit includes all necessary materials for collecting your blood sample at home, along with prepaid return postage for sending the sample to our labs for analysis. Upon analysis, you'll receive a comprehensive report and personalised comments from our medical team, providing valuable insights into your health status and helping you understand the results effectively.

The normal HbA1c level can vary based on age, but there are guidelines for determining a healthy level depending on the stage of diabetes: Non-diabetic: 20-42mmol/L Prediabetes: 42-48mmol/L Diabetes: over 48mmol/L

An HbA1c test is used to test for pre-diabetes or type 2 diabetes in adults. Unlike other tests, it gives you an average blood glucose reading over a period of up to three months rather than at the time of testing. It is considered the gold standard in diabetes testing.

The gold standard test for diagnosing type 2 diabetes is an HbA1c blood test, which provides an average measure of blood glucose levels over the previous 2-3 months.

For individuals without type 2 diabetes, a healthy HbA1c level falls within the range of 20-42mmol/mol.

In the UK, 4.7 million individuals currently have diabetes, with projections indicating that this number will climb to 5.5 million over the next decade. Of those diagnosed, 90% have type 2 diabetes, while type 1 makes up approximately 8%. However, the actual number may be higher as there are an estimated one million undiagnosed individuals with type 2 diabetes in the UK. The growing prevalence of type 2 diabetes poses a significant problem, particularly as it costs the NHS £173 million per week. The surge in obesity is primarily responsible for the uptick in type 2 diabetes cases, with obesity being the leading risk factor for developing the condition. By taking charge of your health and gaining a better understanding of your internal health, you can proactively reduce your risk by making lifestyle changes.

Numerous factors, including obesity or being overweight, physical inactivity, poor dietary habits, diabetes, stress, and certain medications, can all lead to a rise in HbA1c levels.

To effectively reduce your HbA1c levels, it is important to focus on making long-term lifestyle changes. Begin by incorporating more whole, unprocessed foods into your diet, such as fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit your intake of sugary foods and beverages, refined carbohydrates, and saturated fats. Regular physical activity is key in managing HbA1c levels. Aim for at least 150 minutes of moderate-intensity exercise per week, such as brisk walking, cycling, or swimming. Exercise helps improve insulin sensitivity and glucose uptake, leading to better blood sugar control. Stress management techniques, such as meditation, deep breathing exercises, yoga, or spending time in nature, can help reduce cortisol levels and prevent spikes in blood sugar. Adequate sleep is also important for regulating HbA1c levels, so aim for 7-9 hours of quality sleep each night. In addition to lifestyle changes, medications prescribed by your healthcare provider may be necessary to manage your HbA1c levels. Monitoring your progress regularly through at-home blood tests can help you track your improvements and adjust your plan accordingly. With dedication and consistency, you can successfully lower your HbA1c levels and improve your overall health.
