Everything You Need to Know About Vitamin D3
What is Vitamin D3 and why is it important?
Vitamin D3, also called cholecalciferol, is a fat-soluble nutrient made in the skin after sun exposure or taken through diet and supplements. It is essential for bone strength, muscle function, immune support, and overall wellbeing.
What are the main health benefits of Vitamin D3?
Vitamin D3 helps the body absorb calcium and phosphorus, supporting strong bones and teeth. It also contributes to immune defence, muscle health, and may play a role in mood regulation and reducing certain chronic health risks.

How much Vitamin D3 should I take daily?
Most adults need 600–800 IU per day (15–20 mcg). Higher amounts may be required for older adults, people with limited sun exposure, darker skin, or obesity. Always follow local health guidelines or your doctor’s advice.
Should Vitamin D3 be taken in the morning or evening?
Vitamin D3 is best absorbed when taken with a meal containing fat. There is no strict rule on morning or evening, though many people prefer taking it in the morning to align with natural sunlight rhythms.
Can I get enough Vitamin D3 from sunlight alone?
Sun exposure can produce Vitamin D3 in the skin, but factors such as season, latitude, sunscreen use, clothing, and skin pigmentation often limit how much is made. For many people in Europe, supplements are needed year-round or in winter months.
What are the symptoms of Vitamin D3 deficiency?
Signs may include tiredness, frequent infections, muscle weakness, bone or back pain, and low mood. Severe deficiency can cause rickets in children and osteomalacia (soft bones) in adults.
What foods naturally contain Vitamin D3?
The richest sources are fatty fish (salmon, sardines, mackerel), egg yolks, and liver. Some foods such as milk or cereals are fortified. Supplements remain the most reliable source for many people.
Is Vitamin D2 the same as Vitamin D3?
No. Vitamin D2 (ergocalciferol) comes mainly from plant sources, while Vitamin D3 (cholecalciferol) is the form the body naturally makes and is generally more effective at raising and maintaining blood levels of Vitamin D.
Can Vitamin D3 be taken with other vitamins or medications?
Yes, but with caution. It combines well with Vitamin K2 and calcium for bone support. However, very high doses with calcium can increase the risk of high calcium levels. Certain medicines (like steroids or seizure drugs) may interfere with Vitamin D metabolism. Always check with a healthcare professional if you are on medication.
Can you take too much Vitamin D3, and what are the risks?
Yes. While rare, excessive intake over long periods can cause toxicity, leading to high calcium levels (hypercalcaemia). Symptoms include nausea, weakness, kidney issues, and irregular heartbeat. Stick to recommended doses unless advised otherwise by a doctor.
Vitamin D3 K2 (MK-7)
What is the difference between Vitamin D3 and Vitamin K2?
Vitamin D3 helps the body absorb calcium, while Vitamin K2 directs calcium into the bones and teeth instead of arteries or soft tissue. Together, they support strong bones and cardiovascular health.
Why combine Vitamin D3 and K2 in one supplement?
On their own, Vitamin D3 boosts calcium absorption and Vitamin K2 ensures proper calcium distribution. When taken together, they work synergistically to improve bone strength and reduce the risk of unwanted calcium build-up.
Who should consider taking Vitamin D3 + K2?
This combination is especially recommended for people at risk of bone loss, those with limited sun exposure, older adults, and anyone supplementing with Vitamin D3 long-term.
What are the benefits of taking Vitamin D3 + K2 drops instead of tablets?
Liquid drops are quickly absorbed, easy to dose, and gentler on the digestive system. They’re especially convenient for children, older adults, or anyone who struggles with swallowing tablets. Drops also allow for flexible dosing.
How much Vitamin D3 + K2 should I take daily?
Typical daily doses for adults are 1000–2000 IU of Vitamin D3 combined with 50–100 mcg of Vitamin K2. Exact needs depend on age, sun exposure, diet, and health conditions. Always follow your doctor’s advice.
Can I take Vitamin D3 without K2?
Yes, but long-term Vitamin D3 supplementation without K2 may increase the risk of calcium being deposited in arteries rather than bones. Adding K2 ensures calcium is directed to the right places.
Are there natural food sources of Vitamin K2?
Yes. Vitamin K2 is found in fermented foods (like natto), hard cheeses, and animal products such as liver and egg yolks. However, it can be difficult to get enough through diet alone.
Can children take Vitamin D3 + K2 drops?
Yes, but the dosage should be adjusted for age. Drops are particularly suitable for children because they are easy to administer. Always follow paediatric dosing guidelines.
Are there risks or side effects with Vitamin D3 + K2?
When taken within recommended doses, both vitamins are safe. Extremely high doses of Vitamin D3 may lead to high calcium levels, and excessive Vitamin K2 could theoretically increase clotting risk, but this is very rare.
How do I know if I need Vitamin D3 + K2 supplementation?
If you live in a region with little sun exposure, have darker skin, are older, or follow a diet low in dairy or fermented foods, you may benefit. A blood test for Vitamin D status (25(OH)D) is the best way to confirm your needs.
ADEK Vitamin Complex
What is Vitamin ADEC?
ADEC is a multivitamin complex containing fat-soluble vitamins A, D, E, and K, formulated to support immunity, bone strength, antioxidant defence, and healthy blood clotting.
Why are these vitamins combined in one product?
These four vitamins work synergistically. Vitamin D supports calcium absorption, Vitamin K directs it to the bones, Vitamin A aids vision and immunity, and Vitamin E provides antioxidant protection. Together they cover multiple essential functions.
What are the main benefits of taking ADEC?
ADEC contributes to healthy bones, teeth, vision, skin, immune balance, blood clotting, and protection of cells from oxidative stress. It helps cover potential dietary gaps in these vital nutrients.
Who should consider taking Vitamin ADEC?
It is recommended for people with limited sun exposure, diets low in healthy fats, those with increased antioxidant needs, or individuals looking for broad nutritional support in one product.
Why is ADEC often offered in liquid drops?
Since all four are fat-soluble vitamins, drops dissolved in oil improve absorption and bioavailability. Liquid form is also easier to dose and more convenient for children, older adults, or anyone who struggles with tablets.
Can Vitamin ADEC prevent deficiencies?
Yes. Supplementation helps maintain healthy levels of these vitamins, especially when diet, lifestyle, or medical conditions limit natural intake. However, supplements should not replace a varied, balanced diet.
Can you take too much Vitamin ADEC?
Yes. Because these are fat-soluble vitamins, excess amounts can accumulate in the body. Over-supplementation may lead to side effects, especially with Vitamin A and D. Stick to recommended doses unless advised otherwise by a healthcare professional.
Are there interactions with other supplements or medicines?
High doses of ADEC can interact with anticoagulant medication (due to Vitamin K) or amplify effects of calcium supplements (due to Vitamin D). Always consult your doctor if you take prescription drugs.
Is Vitamin ADEC suitable for children?
Yes, but the dosage must be adapted for age and weight. Drops make it easier to give children the exact amount. Always follow paediatric dosing guidelines.
How should Vitamin ADEC be taken for best results?
Take with a meal that contains healthy fats to maximise absorption. Drops can be placed directly under the tongue or mixed with food. Consistency is important — daily use is recommended unless otherwise directed.
Vitamin B Complex
What is Vitamin B Complex?
Vitamin B Complex is a group of eight essential B vitamins (B1, B2, B3, B5, B6, B7, B9, and B12) that work together to support energy production, brain function, and overall health.
What are the benefits of taking Vitamin B Complex?
B vitamins help convert food into energy, support nervous system function, maintain healthy skin and hair, aid red blood cell formation, and contribute to mental focus and resilience against stress.
Who should consider taking Vitamin B Complex?
It is especially beneficial for people under high stress, those with fatigue, vegetarians and vegans (who may lack B12), older adults, and anyone with increased energy needs.
Can Vitamin B Complex improve energy levels?
Yes. B vitamins are directly involved in cellular energy metabolism. While they don’t act as stimulants, they help reduce tiredness and fatigue caused by insufficient intake.
Is Vitamin B Complex good for the brain and mood?
Yes. B vitamins (especially B6, B9, and B12) play a role in neurotransmitter production, which supports memory, concentration, and balanced mood. Deficiency has been linked to low mood and cognitive decline.
How should Vitamin B Complex be taken?
It is best taken daily, ideally with a meal, to improve absorption. Since B vitamins are water-soluble, they are not stored in the body in large amounts, so consistent intake is important.
Can you take too much Vitamin B Complex?
Most B vitamins are water-soluble, and excess amounts are excreted in urine. However, extremely high doses of certain B vitamins (like B6 or niacin) may cause side effects. Always follow recommended doses.
Is Vitamin B Complex suitable for vegans and vegetarians?
Yes. Many B Complex supplements are vegan-friendly. Since Vitamin B12 is mostly found in animal products, vegans in particular often need supplementation.
Can Vitamin B Complex help with hair, skin, and nails?
Yes. Biotin (B7), riboflavin (B2), and niacin (B3) are known to contribute to healthy skin, hair, and nails. That’s why B Complex is often included in beauty and wellness routines.
What are the symptoms of Vitamin B deficiency?
Deficiency symptoms vary depending on the vitamin but may include fatigue, irritability, anaemia, poor memory, skin rashes, and tingling in hands or feet. Severe long-term deficiency can lead to serious neurological issues.
