They work!

Been taking these 2 weeks now and already feeling the benefits, 47yrs old going through perimenopause I am suffering with joint pain, low energy and sleep problems but I am sleeping so much better, energy levels have risen and reduced joint problems. I work as a carer on a dementia unit 12hr shifts and if I do 2-3 shifts in a row I am in so much pain in a morning and shuffling about but I have just done 3 shifts in a row and was fine this morning! Highly recommended

Frequently Asked Questions

Common questions about Vitamin D3 4000iu + K2

Vitamin D deficiency is common, especially in regions with limited sunlight exposure or for individuals who spend most of their time indoors.

A deficiency in vitamin D can lead to a range of symptoms, such as persistent fatigue, bone pain, muscle weakness, and mood changes, all of which can significantly impact a person's quality of life.

Fatigue may reduce the ability to concentrate and perform daily tasks, leading to a decrease in overall productivity and well-being.

Bone pain and muscle weakness can make physical activities more difficult and uncomfortable, potentially limiting mobility and causing a loss of independence.

Additionally, mood changes such as irritability, anxiety, or even depression may strain personal relationships and diminish one's sense of mental and emotional balance. Over time, these symptoms may reduce an overall enjoyment of life and ability to engage in everyday activities.

The National Health Service (NHS) in the UK recommends that everyone consider taking a daily vitamin D supplement, particularly during the autumn and winter months. If you're unsure, a healthcare professional can perform a simple blood test to check your vitamin D levels and determine if supplementation is necessary.

Choosing the right vitamin D supplement can be confusing given the various options available. Here's a brief overview of each to help you decide:

Vitamin D3 1000iu: This is a standard option providing the daily amount of 1000iu of Vitamin D3. It's suitable for general maintenance and support of overall health.

Vitamin D3 4000iu: If you're looking for a higher potency supplement, this option contains 4000iu of Vitamin D3 per serving. Some individuals with specific health concerns can benefit from this dosage

Vitamin D3 4000iu+K2: This combines 4000iu of Vitamin D3 with Vitamin K2, which supports optimal calcium absorption and utilisation in the body. The combination of D3 and K2 can offer additional benefits for bone and heart health.

For each person the amount of Vitamin D required could vary (both higher and lower dosage) depending on how much time they spend out in the sun, as well as their skin colour (if you have darker skin, you absorb less Vitamin D outside).

If you are interested in Vitamin D3+K2 and feel that the 4000iu strength is too high, there is an option to spread taking them once every four days instead of daily. This approach can be effective because Vitamin D3 and Vitamin K2 are fat-soluble, meaning it can be stored in the body's fat tissues and liver for future use. Therefore, it doesn't necessarily need to be replenished every day like water-soluble vitamins (e.g., Vitamin C, B vitamins).

The Department of Health and Social Care in the UK recommends that adults and children over 4 years old should take a daily Vitamin D supplement containing 400IU. It's important to note that the required amount of Vitamin D may vary for each individual, depending on factors such as sun exposure and skin color. Those with darker skin tend to absorb less Vitamin D from sunlight.

For children aged 9 and above, a dose of 1000IU of Vitamin D3 can be appropriate and safe, with the option to adjust the frequency, such as once every other day during summer months.

Our Vitamin D3+K2 supplement is of higher strength (Vitamin D3 4000IU and Vitamin K2 1000IU). If you find the 4000IU strength too high, you can opt to take them once every 2-3 days instead of daily. This approach can be effective because both Vitamin D3 and K2 are fat-soluble, meaning they can be stored in the body's fat tissues and liver for future use.

Moreover, according to the NHS, taking 1000IU or less of vitamin K supplements a day is unlikely to cause any harm.

However, we strongly recommend consulting your GP or pharmacist for personalised advice based on the child's medical history.

Vitamin D3 and K2 work synergistically to optimise calcium metabolism. Vitamin D3 increases calcium absorption in the intestines, while Vitamin K2 directs the calcium to the bones and prevents it from depositing in the arteries and blood vessels. This combination ensures that your body uses calcium effectively, supporting both bone health and cardiovascular health.
