☀️ The Sunshine Vitamin

4000 IU Vitamin D3.
2000% of NRV. In a single gummy.

The most important vitamin your body does NOT produce enough of. Natural orange flavor. Sugar-free.

💡 Why do 90% of Europeans have a Vitamin D deficit? We live at northern latitudes, spend 80% of our time indoors, and food contains minuscule amounts. Your skin can't synthesize enough D3 from November through April. The symptoms? Chronic fatigue, weak immunity, bone pain, poor mood. It's not "laziness" — it's a deficiency.

🧬

Bones & Teeth

💪

Muscles

Maintains normal muscle function and reduces the risk of cramps

🛡

Immunity

Normal function of the immune system — your body's first line of defense

🧠

Mood

Studies show a link between D3 deficiency and mood disorders, including SAD

🔬

Blood Calcium

Maintains normal blood calcium concentrations — vital for nerve function

🥀

Cell Division

Participates in the process of cell division — essential for regeneration and healing

Why 4000 IU?

The standard dose of 400–800 IU isn't enough. Here's why we chose an optimized dose.

📈

The Dose That Matters

Studies show that 4000 IU/day is the optimal dose for adults with a deficit — the perfect balance between efficacy and safety. It is the tolerable upper intake level set by EFSA.

4000 IU = the dose most frequently recommended by doctors

🌞

Cholecalciferol — the Natural Form

D3 (cholecalciferol) is the same form your skin produces when exposed to sunlight. It is 87% more effective than D2 (ergocalciferol) at raising blood levels of 25(OH)D.

Not D2, not synthetic analogs — authentic D3

🍊

With Orange Essential Oil

Sweet orange essential oil (Citrus sinensis) — adds natural flavor and contains d-limonene, a terpene with antioxidant properties. D3 is fat-soluble, so it absorbs better with fats.

Natural flavor, not artificial

Active Ingredients

☀️ Vitamin D3 (Cholecalciferol) 100mcg / 4000IU

Cholecalciferol — the active form, identical to what your skin produces when exposed to sunlight. At 4000 IU (100 mcg), it represents 2000% of NRV — a therapeutic dose validated by clinical studies for correcting deficiency. D3 regulates calcium absorption, immune function, bone and muscle health.

📚 4000 IU = the optimal dose for adults with vitamin D deficiency

🍊 Sweet Orange Essential Oil 2mg

Citrus sinensis — natural essential oil that provides the orange aroma and taste. Contains d-limonene, a natural antioxidant. Being fat-soluble, vitamin D3 benefits from the presence of lipid compounds for optimal absorption.

Frequently Asked Questions

Why 4000 IU and not a lower dose? +

4000 IU (100mcg) is the upper safe daily limit set by EFSA for adults. This dose is especially suitable for individuals with vitamin D deficiency, those who spend long hours indoors, or live in regions with limited sun exposure. If you have not had a blood test for vitamin D, consult your doctor to determine the right dose for you.

Can I take these gummies year-round? +

Yes. Vitamin D is an essential nutrient year-round. In many European regions, sun exposure is insufficient for adequate vitamin D synthesis for approximately 6-7 months per year (October-April). But even in summer, many people do not get enough sun exposure. Vitamin D contributes to the normal function of the immune system and to the maintenance of normal bones.

Are they sugar-free? Are they safe for diabetics? +

The gummies are sweetened with maltitol and xylitol - no added sugar. Maltitol has a lower glycemic index than sugar, but it is not zero. If you have diabetes, please consult your doctor before use, taking into account the carbohydrate content per gummy.
