How to choose the best product? 

Before selecting a product, it is essential to check vitamin D levels in serum. In case of deficiency symptoms, check the Welzo Vitamin D Blood Test to determine vitamin D levels in the blood. The levels below 12 ng/mL reflect severe vitamin D deficiency.

If the blood tests confirm the deficiency, consult the healthcare provider for a suitable product according to personal needs. Routine testing for vitamin D levels is recommended to identify deficiencies before the appearance of signs.

Frequently Asked Questions

What is the difference between D2 and D3?

Vitamin D naturally exists in two forms, D2 and D3. D3 is derived from animals and is more effective in raising blood vitamin D levels than blood plant-based D2.

What is the best Vitamin D supplement? 

Many products fulfil the criteria of ‘the best’ product. The top products in our ranking are Lamberts Maximum Strength Vitamin D3, VITABIOTICS Ultra Vitamin D and Pure Encapsulation Vitamin D3. 

Which form of vitamin D is most effective? 

The most effective form of vitamin D is vitamin D3. It is naturally produced in the bodies of humans and animals. This form is more effective in raising vitamin D levels in serum than D2.

What are the signs of vitamin D deficiency that necessitate supplements? 

The critical signs of vitamin D deficiency that need immediate attention and must not be ignored are bone aches and pain, sad feelings and depression, sleeping issues, fatigue, hair loss, muscle weaknesses, poor appetite and increased frequency of illnesses. 

What is the other name of vitamin D? 

The other name for vitamin D is calciferol. It is a fat-soluble vitamin, with D2 and D3 being the two different forms. 

How much vitamin D is recommended for different ages? 

The recommended daily dose of vitamin D is 15 mcg (600 IU) for teenagers, adults, pregnant and breastfeeding women and 20 mcg (800 IU) for those above 70 elders. The Doctors often recommend higher doses to correct severe deficiencies. The Royal Children’s Hospital recommends a daily dose of 50 mcg (2000 IU) in severely deficient children for a minimum period of 3 months. 

Can vitamin D supplements be taken without consulting the doctor? 

It is a fat-soluble vitamin, and excessive amounts are stored in different body tissues and cause vitamin D toxicity. This situation results in gastrointestinal upsets, bone and muscle weakness, calcification of soft tissues and kidney stones. Therefore, it is strongly advised to consult the healthcare provider for proper dosages and better safety. 

What are the other ways to boost vitamin D levels quickly? 

Restoring the vitamin D levels needs a holistic approach to healthcare. The best strategies are eating vitamin D-rich foods, e.g., fish, cereals, milk, etc., having moderate exposure to sunlight and taking an appropriate vitamin D3 supplement when necessary. 

Is it safe to take 5000 IU of vitamin D daily? 

According to the Harvard School of Public Health, the safe upper limit for vitamin D is 100 mcg (4000 IU), and it is not recommended to take more unless advised by the healthcare provider. It is a fat-soluble vitamin, and the body does not quickly lose excessive amounts. 

Which vegetables are rich in vitamin D? 

For vegans, the best choice is to increase the use of vitamin D-rich vegetables, mainly white beans, soybeans, collard, spinach, kale and okra.

Bottom-line 

The top 10 best products in the market suiting the needs and requirements of various people are described. Vitamin D is a fat-soluble vitamin and a good tip for optimum absorption is to take it with a fatty meal, e.g., peanut butter, olive oil or avocado oil. Self-selection is not advised; it is critical to consult the nutritionist or GP about dosing and safety.
