Vitamin D2 (ergocalciferol) is a form of the “sunshine vitamin” often chosen by vegetarians and those who consciously avoid animal-based ingredients. Solaray offers it in a dry form, 25 mcg (1,000 IU) per capsule, in vegetable-based VegCap capsules.
Composition and form of release
One capsule contains 25 mcg (1000 IU) of vitamin D₂ in the form of ergocalciferol - a plant analogue of vitamin D, synthesized from yeast or mushrooms under the influence of ultraviolet light. This is a fundamental difference from D3 (cholecalciferol), which is usually obtained from lanolin or fish oil.
Other ingredients: vegetable cellulose (capsule), rice flour, organic rice blend extract, silicon dioxide. No gelatin, no animal ingredients.
The package contains 60 vegetarian capsules, which corresponds to a two-month course with a standard intake of 1 capsule per day.
Vitamin D2 and D3 - what's the difference?
D2 (ergocalciferol) and D3 (cholecalciferol) are two forms of the same nutrient that the body converts into the active form 25(OH)D, or D25-one. Both forms support the absorption of calcium and phosphorus, which are essential for healthy bones and teeth.
Ergocalciferol is derived exclusively from plant and fungal sources - making D2 a natural choice for vegetarians and vegans. The different forms may differ in metabolic rate, but both are recognized sources of vitamin D in the daily diet.
Dry form: why is it important?
Vitamin D is a fat-soluble nutrient and is traditionally available in oil-based capsules. Solaray uses a dry form of ergocalciferol: it is more stable during storage, less sensitive to temperature fluctuations, and convenient for those who prefer a minimal composition without carrier oils.
How much vitamin D2 should you take per day?
The manufacturer recommends taking 1 capsule daily with a meal or a glass of water. One capsule provides 25 mcg (1000 IU) of vitamin D₂. Taking with meals promotes better absorption of fat-soluble nutrients.
The optimal dosage depends on your baseline 25(OH)D blood levels, the season, and your lifestyle. It is a good idea to consult your doctor before taking it for a long period of time - especially if you are already taking other vitamin D supplements.
When is vitamin D2 relevant?
Vitamin D is synthesized in the skin under the influence of solar ultraviolet - hence its unofficial name "sunshine vitamin". In the conditions of the autumn-winter season, cloudy climate or predominantly office lifestyle, natural synthesis is significantly limited.
Food sources of D2 include mushrooms, some algae, and fortified foods. For those who do not consume fatty fish or eggs and are looking for a plant-based source of this nutrient, ergocalciferol capsules can be a convenient addition to their diet.
Who is this format suitable for?
- Vegetarians and vegans - without animal ingredients, VegCap vegetable capsule.
- Those who avoid oil capsules or are looking for a dry form of vitamin D.
- Adults who want to support their daily diet during periods of limited sunlight.
- Those who consciously choose D2 as a plant-based alternative to D3.
