Vitamin D2 (>8000 IU/g) — from Shiitake

With-Meal Capsule: For ≈800–1000 IU D2, use ≈100–125 mg powder (8 IU per mg at >8000 IU/g). Take with a meal that includes oils.

Sachet To-Go: Pack ≈100–125 mg sticks (≈800–1000 IU) for a tidy daily habit; mix into smoothies or milk alternatives.

Gummies: To deliver ≈400–800 IU per 4 g gummy, use ≈50–100 mg powder (≈1.25–2.5% w/w); pilot flavour/acid balance.

Smoothie Add-In: 100 mg into a breakfast smoothie with nut or seed fats for practical dispersion.

Stack Idea: Pair with a simple K2 routine or magnesium; add one change at a time and track adherence.

Vegan D-Vitamin Source: Mushroom-derived D2 suits plant-forward, clean-label builds.

Predictable IU Math: >8000 IU/g simplifies micro-dosing for capsules and gummies.

Format-Friendly: Neutral taste and fine texture work across capsules, gummies, sachets and smoothies.

Routine-Ready: Fits food-first, with-meal habits without stimulants.

Serving Size: 1 capsule or scoop (≈ 100–125 mg powder ≈ 800–1000 IU D2)

Ingredients: Vitamin D2 (>8000 IU/g) Extract Powder (from UV-activated Lentinula edodes fruiting bodies)

Does Not Contain: Added sugar, caffeine, artificial colours

Allergen Information: Vegan; gluten-free; dairy-free. Fungi-derived; review if sensitive to mushrooms.

Usage Recommendation: Take ≈100–125 mg once daily with meals. If stacking with other actives, add one change at a time and space ~90 minutes from medications as a routine practice.

Storage Advice: Store cool, dry & dark. Keep tightly sealed away from direct sunlight.

Keep Away From Children

Q: How do I place plant-derived Vitamin D2 (>8000 IU/g) into a simple daily routine?

A: Keep it tied to the same mealtime and include some dietary fats. A practical starting point is 100–125 mg powder, giving roughly 800–1000 IU at 8 IU per mg. Hold the rest of your routine steady—sleep, hydration, meal timing, and steps—so you can actually observe the effect of this one change. Run the same serving for two to four weeks before adjusting. If you’re building a stack later, add only one new variable at a time and track adherence and workflow friction; the goal is a repeatable habit you can maintain on real days, not perfect days.

Claim-strength scale – High = multiple human studies; Moderate = a few trials; Emerging = early lab data.

Q: What’s the practical difference between mushroom-derived D2 and other D-vitamin formats for formulation?

A: This ingredient supplies ergocalciferol (D2) within a mushroom matrix from UV-activated Lentinula edodes, which many formulators choose for vegan, clean-label positioning. Other formats (e.g., lanolin/lichen-derived D3) offer different source stories and potencies. Choose by build and workflow: capsules favour precision; gummies and sachets favour ease and habit sticking. Whatever you pick, lock the serving to a consistent meal, document pilot variables (flavour, acids, oils), and avoid frequent product switches that blur evaluation and complicate SOPs.

Q: How do I set gummy strength without overcomplicating the formula?

A: Decide the per-gummy target first—say 400 or 800 IU—then back-calculate powder using 8 IU per mg: ≈50 mg or ≈100 mg in a 4 g pectin gummy (≈1.25–2.5% w/w). Keep acids and flavours consistent, disperse thoroughly to avoid hot spots, and document every batch variable. Store cool and dark; heat and light can degrade D-vitamins. Run a small stability check before scaling, then lock your SOP once taste, texture and assay uniformity meet targets for repeatability and label confidence.

Q: Can I stack D2 with K2 or magnesium without overcomplicating things?

A: Yes—start with one anchor habit first: 100–125 mg D2 powder at a consistent meal. After a week, consider adding a K2 routine or magnesium if it fits your build, keeping timing and portion sizes steady. Leave ~90 minutes from medications as a general routine practice. Track comfort, adherence, and any workflow friction (capsule vs gummy vs stick) in a simple log. Adjust gradually rather than chasing higher totals; the goal is a routine you can sustain long enough to evaluate results clearly.
