Wholesale Shiitake Mushroom Extract From Vitamin D₂: Anti Aging Ingredient

Shiitake (Lentinula edodes) is a highly cultivated edible mushroom known to contain ergosterol, which can be converted into vitamin D₂ (ergocalciferol) through exposure to UV‑light wholesale shiitake mushroom extract fortified with vitamin D₂ is sourced from cultivated shiitake fruiting bodies that undergo controlled post‑harvest UV irradiation to elevate D₂ levels for use in skincare and nutraceutical formulations.

Manufacturing Process Of Shiitake Mushroom Extract From Vitamin D₂

1. Harvest & Cleaning – Fresh shiitake fruiting bodies are cleaned and optionally sliced or finely chopped to increase surface area (typically 0.5–3 mm slices or chopped pieces), which enhances UV conversion.

2. UV Irradiation – Samples are exposed to UV‐B (around 280–300 nm) and sometimes UV‑C wavelengths under controlled doses (e.g. 1.5–4 J/cm² for 100–180 min; UVC may follow) to convert ergosterol into vitamin D₂.

3. Drying & Crushing – After irradiation, the material is dried and ground to fine powder or oil‐extracted slurry.

4. Extraction (Powder or Oil)

• Powder form: ethanol or solvent extraction (e.g. reflux with ethanol, alkaline saponification, hexane partition, concentration and HPLC purification) to concentrate D₂

• Oil form: mixing with edible oil (sunflower, rapeseed, etc.), extraction under vacuum and nitrogen for many hours, then plate‑and‑frame filtration to produce vitamin D₂‑enriched mushroom oil

5. Standardization & QC – High‑performance liquid chromatography (HPLC) is used to quantify vitamin D₂, ensure ergosterol conversion, and certify purity and microbial/heavy‑metal safety.

Undersun product offers a natural, vegan‑friendly anti‑aging ingredient derived from shiitake mushrooms. The patented UV conversion and extraction protocols ensure high vitamin D₂ content and consistent quality.

Anti-Aging & Commercial Uses

Vitamin D₂is known for its antioxidant activity and support of skin barrier and repair processes, making it suitable for anti‑aging topical ingredients in skincare creams, serums, masks and supplements. Although vitamin D₃is more bio‑available in humans, D₂remains a widely accepted functional ingredient within vegan-certified, natural product lines. Commercial uses include:

From Shiitake Mushroom Extract From Vitamin D₂For Customer Cases

1. Bone Health / Osteoporosis Support (Post-menopausal Women)

A pre‑clinical study using UV‑irradiated shiitake powder administered to ovariectomized rats showed improved femoral bone mineral density and trabecular architecture compared to controls on vitamin D-deficient diets. Vitamin D₂ was bioavailable, and bone structure markers were mitigated. This supports commercial use in women's supplements targeting bone strength and menopausal support.

2. Immune-Modulation & Liver Protection (Functional Wellness)

In a mouse model of immune-mediated hepatitis, vitamin D₂‑enriched shiitake extracts were shown to significantly reduce liver injury markers (ALT, AST), lower interferon‑γ levels, and improve histological outcomes versus non‑enriched mushroom extracts. A synergistic anti-inflammatory benefit was noted beyond vitamin D alone

A nutraceutical developer launching an immune‑support line included the extract as an adjuvant for liver-support formulations with humanized ingredients.

3. Vitamin D Maintenance in Active Individuals

A randomized trial involving recreationally active volunteers compared mushroom-derived D₂ capsules (1,000 IU/d) with D₃ capsules and placebo over 12 weeks. The D₂ group saw a 347 % rise in serum 25‑OH‑D₂ and maintained total vitamin D status similar to placebo, whereas D₃ markedly increased total 25‑OHD. While D₂ alone had modest effects, it was effective in maintaining baseline levels in vitamin‑D‑insufficient subjects.

A supplement brand including the extract in vegan sports multivitamins aimed at maintaining wellness during low-sun periods.

4. Consumer Dietary Trials (Human Supplementation Study in India)

In an open-label randomized trial with vitamin‑D–deficient participants aged 21–45, daily intake of shiitake‑based D₂ soup (prepared from UV-irradiated shiitake powder) for four weeks was compared to a commercial 50,000 IU D₂ capsule and placebo. The shiitake soup group experienced measurable rises in serum 25‑OHD over ~36 days, which tracked comparably to the high‑dose capsule group.

A illustrates consumer acceptance and efficacy in functional foods or sachet‑based supplements targeted at deficient populations.
