BIOVIT Vitamin D2
Natural source: Shiitake Mushroom
Vegan Vitamin D2 from UV-exposed shiitake
Mushrooms are the only non-animal food that produces Vitamin D when exposed to sunlight. BIOVIT's extract is produced by UV-exposing organically cultivated shiitake, mimicking the natural process, to deliver Vitamin D2 (ergocalciferol) at 10 mg per 100g from a single recognisable plant source.
Organic certified, GB and EU compliant, and a direct one-to-one replacement for synthetic ergocalciferol across vegan, mushroom-positioned, and plant-based ranges where a fungal D source matters.
Specified by leading UK manufacturers, with samples dispatched within a week and reformulation support included.

From plant-based dairy to powdered shakes
D2 is the choice for brands wanting a fully fungal-derived Vitamin D declaration on pack, particularly in mushroom-positioned and vegan ranges where source storytelling matters as much as the claim itself. Three categories where shiitake D2 earns its place fastest.
Plant-based dairy
Vitamin D fortification is the unspoken benchmark in oat, soy, and almond milks targeting cow's milk parity. A shiitake declaration aligns the back-of-pack with the natural positioning of the category, and pairs cleanly with B12 from the same source.
Supplements
Capsules, tablets, and powders for mushroom-positioned brands, vegan ranges, and functional mushroom products where the fungal source is part of the storytelling. The negligible 0.0075 g inclusion rate sits comfortably alongside other nutrients in multi-format stacks.
Powdered shakes
Dry blending compatible across protein, recovery, and functional mushroom formats. D2 holds claim integrity through long shelf lives and pairs naturally with B12 in dual-mushroom positioning.

Frequently asked questions
Common questions on specifying shiitake-derived Vitamin D2, covering the D2 vs D3 distinction, vegan suitability, bioavailability, and EFSA claim coverage.
D2 (ergocalciferol) is shiitake-derived and fully vegan. D3 (cholecalciferol) is lichen-derived and also vegan. Research indicates D3 is more effective at raising and sustaining serum 25(OH)D levels, but D2 is the choice for brands wanting a mushroom-sourced declaration aligned with a functional-mushroom or fungal-positioned range.
Vitamin D was one of eight micronutrients measured in BIOVIT's 30-day human intervention trial at Swansea University (61 volunteers, UKRI-funded, led by Prof Richard Bracken). The trial confirmed equivalent bioavailability between the natural and synthetic groups across the nutrients measured, supporting the position that shiitake-derived D2 performs in line with synthetic ergocalciferol.
Organically cultivated shiitake mushrooms are exposed to controlled UV light, replicating the natural process by which mushrooms convert ergosterol to ergocalciferol in sunlight. No chemical synthesis, no animal derivation, and a fully fungal source declaration on pack.
Yes. 100% plant-based and suitable for vegan, vegetarian, and plant-based products. Particularly relevant for mushroom-positioned ranges, functional mushroom brands, and adaptogenic products where the fungal source is part of the proposition.
"Organic shiitake mushroom extract." A recognisable food declaration that reads far cleaner than "ergocalciferol" or "Vitamin D2 (synthetic)" on a label.
0.0075 g per portion for "Source of", 0.0150 g for "High in". For a precise cost figure in your formulation, get in touch with the team.
Samples and commercial orders are dispatched within around a week of order confirmation, with full technical documentation included. The MOQ is 1 kg on standard powder format. Bespoke formats and pack sizes available on request.
Yes. Every wholesale order comes with full reformulation support from BIOVIT's Head of Nutrition, Eiméar Sutton RNutr MSc. That includes equivalence mapping against your incumbent Vitamin D source, inclusion-rate modelling, and on-pack claim wording aligned to GB and EU regulation, at no extra cost.
Vitamin D2 contributes to the following EU-authorised health claims under EFSA Regulation (EC) No 1924/2006:
Normal function of the immune system
Maintenance of normal bones
Maintenance of normal teeth
Normal absorption and utilisation of calcium and phosphorus
Maintenance of normal muscle function
Maintenance of normal blood calcium levels
Has a role in the process of cell division
Normal growth and development of bone in children
Normal function of the immune system in children
Calcium and vitamin D help to reduce the loss of bone mineral in post-menopausal women. Low bone mineral density is a risk factor for osteoporotic bone fractures (EU only)
Vitamin D helps to reduce the risk of falling associated with postural instability and muscle weakness. Falling is a risk factor for bone fractures among men and women 60 years of age and older (EU only)
Reformulation support is included
Every BIOVIT wholesale order comes with full technical reformulation support at no extra cost, giving your NPD and technical teams direct access to a qualified nutritionist from brief to production.
Eiméar Sutton (RNutr MSc), our Head of Nutrition, leads the technical work on every account: equivalence mapping against your incumbent synthetic, inclusion-rate modelling, on-pack claim wording aligned to GB and EU regulation, and the small details that decide whether a synthetic-to-natural switch lands cleanly on the production line.
The result: shorter development cycles, fewer reformulation rounds, and a finished product your commercial team can stand behind.
