The "Sunshine Vitamin" Problem in India
India gets plenty of sunshine — yet studies show that 70–90% of Indians are Vitamin D deficient. Desk jobs, sunscreen use, darker skin tones that require longer sun exposure, and spending most of the day indoors all work against us.
The result? Tired bones, low energy, a sluggish immune system, and poor calcium absorption — all quietly linked to not getting enough Vitamin D.
How Much Vitamin D3 Do You Actually Need Every Day?
The Indian Council of Medical Research (ICMR) and the World Health Organization (WHO) recommend 600 IU (International Units) of Vitamin D3 per day for healthy adults aged 19–70 as the Recommended Daily Allowance (RDA).
This is the amount your body needs to:
- Keep bones strong by helping absorb calcium from food
- Support your immune system to fight off infections
- Maintain healthy muscle function and reduce the risk of falls
- Support heart health and general well-being
600 IU daily is not a "minimum" — it is the scientifically established sweet spot for maintaining healthy Vitamin D levels in most adults when taken consistently.

So Why Do Doctors Sometimes Prescribe 2,000 IU, 5,000 IU, or Even 60,000 IU?
Higher doses are therapeutic, not maintenance doses. They are prescribed for a limited period to correct a deficiency that has already developed. Think of it like this: if your phone battery is at 5%, you need a fast charger to get it back up quickly. But once it's at 100%, you just need a regular charger to keep it there.
| Dose | When It's Typically Used |
|---|---|
| 600 IU/day | Daily maintenance for healthy adults — the RDA |
| 1,000–2,000 IU/day | Mild deficiency or for people with limited sun exposure |
| 5,000 IU/day | Moderate deficiency, often prescribed for a few weeks |
| 60,000 IU/week | Severe deficiency — a short-term "loading dose" prescribed by a doctor, typically for a few weeks |
Important: Doses above 2,000 IU should only be taken under a doctor's guidance. Once your levels are corrected, your doctor will typically bring you back to a daily maintenance dose — which is where 600 IU comes in.

Once Your Levels Are Corrected — Then What?
This is the part most people miss. After completing a high-dose prescription course, many people stop supplementing altogether — and within months, their Vitamin D levels drop again.
The solution is simple: a consistent daily maintenance dose of 600 IU.
This is exactly what Nutrazee Vegan Vitamin D3 is designed for — a clean, daily habit that keeps your Vitamin D levels in the healthy range, year-round.
Introducing Nutrazee Plant-Based Vitamin D3 — Your Daily Sunshine in a Capsule
100% Plant-Based — Sourced from Lichen
Most Vitamin D3 supplements on the market are derived from lanolin (sheep's wool). Nutrazee Vegan Vitamin D3 is sourced from Lichen — a plant organism and the only known plant source of Vitamin D3. This makes it suitable for vegans, vegetarians, and anyone who prefers a clean, plant-based lifestyle.
Powered by Vitashine® D3
Our Vitamin D3 is powered by Vitashine® — the world's first Vitamin D3 ingredient to be registered with both the Vegan Society and the Vegetarian Society. This is not just a marketing claim; it's a certified, globally recognised standard.
Formulated with Organic Cold-Pressed Coconut Oil
Vitamin D3 is a fat-soluble vitamin — meaning it is absorbed much better when taken with a fat source. Each Nutrazee capsule is liquid-filled with organic cold-pressed coconut oil, which helps your body absorb the Vitamin D3 efficiently. No need to plan your supplement around a heavy meal.
Liquid-Filled HPMC Vegetarian Capsule
The capsule shell itself is made from HPMC (Hydroxypropyl Methylcellulose) — a plant-derived material, not gelatin. So every part of this supplement is 100% vegetarian and vegan-friendly.
Exactly 600 IU — 100% RDA Per Capsule
Each capsule delivers precisely 600 IU of Vitamin D3 — 100% of the Recommended Daily Allowance. No guesswork, no overdoing it. Just the right amount, every day.
One Capsule a Day — 60 Capsules = Two Months' Supply
One pack of 60 capsules gives you a full two-month supply at one capsule per day. Simple, consistent, and cost-effective.
What Does Vitamin D3 Actually Do for Your Body?
- Stronger Bones & Teeth — Vitamin D helps your body absorb calcium, which is the building block of bones. Without enough Vitamin D, calcium from your food goes to waste.
- Healthy Muscles & Joints — Low Vitamin D is linked to muscle weakness and joint discomfort. Keeping levels topped up supports an active lifestyle.
- Immune System Support — Vitamin D plays a key role in how your immune system responds to infections. Consistent levels help your body stay ready.
- Heart Health — Research suggests healthy Vitamin D levels are associated with better cardiovascular health.
- Energy & Mood — Many people report feeling more energetic and less fatigued when their Vitamin D levels are in the healthy range.
Who Should Consider a Daily Vitamin D3 Supplement?
- Office workers and students who spend most of the day indoors
- Anyone living in cities with high pollution (which blocks UV rays)
- People who use sunscreen regularly
- Vegetarians and vegans (most food sources of Vitamin D are animal-based)
- Women, especially those planning a pregnancy or post-menopause
- Men and women over 40, as the skin's ability to produce Vitamin D from sunlight decreases with age
- Athletes and active individuals who need strong muscle and bone support
- Anyone who has completed a high-dose prescription course and wants to maintain their levels
How to Take Nutrazee Vegan Vitamin D3
Take one capsule daily, preferably with a meal. Since the capsule already contains coconut oil, absorption is optimised even with a light meal. For best results, take it at the same time each day to build a consistent habit.
Frequently Asked Questions
Can I take 600 IU every day long-term?
Yes. 600 IU is the established RDA for healthy adults and is considered safe for long-term daily use. The Tolerable Upper Intake Level (UL) set by health authorities is 4,000 IU/day — so 600 IU leaves a very wide safety margin.
Is plant-based Vitamin D3 as effective as regular Vitamin D3?
Yes. Lichen-sourced Vitamin D3 (cholecalciferol) is chemically identical to animal-derived Vitamin D3 and has the same effect in the body.
Do I still need a supplement if I go out in the sun?
Sun exposure can help, but factors like time of day, season, skin tone, sunscreen use, and pollution significantly reduce how much Vitamin D your skin actually makes. A daily supplement ensures you consistently hit your target regardless of these variables.
Can I take this after completing a 60,000 IU prescription course?
Yes — this is actually one of the most common use cases. Once your doctor confirms your levels are corrected, switching to a daily 600 IU maintenance supplement like Nutrazee Vegan Vitamin D3 is the recommended approach to keep levels stable.
The Bottom Line
Vitamin D deficiency is one of the most common and most overlooked health issues in India. The fix is straightforward: 600 IU of Vitamin D3 every single day, from a clean, reliable source.
Nutrazee Vegan Vitamin D3 makes that easy — plant-based, coconut oil-enhanced, precisely dosed, and certified vegan. One capsule a day is all it takes.
