Notes
  • Around 1 in 6 adults in the UK have low levels of vitamin D (lower than government recommendations), while, according to the National Institutes of Health, they should be above 30 nmol/L, with the maximum level being 125 nmol/L.
  • Common symptoms of vitamin D deficiency: fatigue, frequent illnesses, muscle and back pain, osteoporosis, hair loss, depression, weight gain, and tooth decay.
  • Only 10% of vitamin D comes from food, as the primary source is sunlight. This makes it difficult for many people to get the necessary amount of the "sunshine vitamin" through diet alone.
  • Main dietary sources of vitamin D: fatty fish (tuna, mackerel, salmon), eggs, dairy products (milk, cheese), beef liver, and fortified foods (cereals, bread, juices).

Notes
  • According to the NHS, the recommended daily dose of vitamin D for adults is 10 mcg or 400 IU. The safe upper limit is 100 mcg (4,000 IU) per day.
  • According to the Birmingham NHS Trust data most adults need 2,000–3,000 IU per day (50–75 mcg) to maintain healthy blood levels of vitamin D.
  • If your vitamin D levels rise to 5,000–10,000 nmol/L in 2-3 months, you should check for issues with fat absorption, adjust the dosage, or change the supplement formula.
  • If your vitamin D levels reach 15,000–20,000 nmol/L in 2-3 months, absorption is good, and you can balance the dosage according to your goals for vitamin D levels in your blood.
  • Vitamin D is recommended during the winter and autumn months, but year-round supplementation is also beneficial. The key is to personalize the dosage for your body's needs.
  • If you need help determining the right dosage or are unsure about anything, feel free to contact me for a 30-minute consultation.

Notes
  • Vitamin D is best taken in the first half of the day with foods containing fats (such as nuts, fish, eggs, and oils).
  • To avoid calcium buildup in blood vessels and to ensure calcium is not drawn from bones, it’s important to take vitamin D with vitamin K2 and magnesium, especially if you are taking more than 4,000 IU of vitamin D per day.
  • The daily dose of vitamin K2 is 1 mcg per kg of body weight. The maximum safe dose is 1 mg per day.
  • The average daily dose of magnesium is 400 mg, but you may need more or less depending on your diet and daily magnesium usage.
