In recent years, Vitamin D has gained global attention — and for good reason. Many health experts now believe it’s one of the most powerful and underappreciated nutrients in the world.
One of the leading voices in this movement is Dr. Michael F. Holick, the author of “The Vitamin D Solution.” His research has helped millions understand how Vitamin D can change your life — from stronger bones to a better immune system, and even improved mood and energy.
Let’s break down some of the key takeaways from his groundbreaking book — and how this connects to I-FERN’s mission of promoting health and wellness through high-quality Vitamin D3 (cholecalciferol) product called FERN-D.
What is The Vitamin D Solution?
Dr. Holick’s message is simple: Vitamin D deficiency is a global epidemic.
His book shares decades of medical research, real-life patient stories, and practical advice on how to:
- Prevent and treat Vitamin D deficiency
- Improve your immune system
- Reduce the risk of chronic illnesses like heart disease, diabetes, and even depression
- Maintain strong bones and avoid osteoporosis
The Shocking Truth: Most People Don’t Get Enough Vitamin D
According to Dr. Holick, even people who get sunlight daily can still suffer from low Vitamin D levels — due to:
- Sunscreen use
- Staying indoors
- Darker skin tones (which naturally absorb less UVB)
- Aging (older people produce less Vitamin D from sunlight)
The Recommended Solution: Supplement with Vitamin D3
Dr. Holick recommends Vitamin D3 (cholecalciferol) as the most effective form of supplementation — and it’s exactly what you’ll find in FERN-D.
He suggests that adults may need at least 2000 IU daily, depending on their lifestyle, skin color, and exposure to sunlight. FERN-D contains 1000 IU per softgel, making it easy to adjust based on your needs.
Why I Trust FERN-D?
I-FERN’s FERN-D is not just another supplement. It’s:
- FDA-approved and HALAL-certified
- Manufactured with DSM Switzerland’s Quali-D®, a world leader in Vitamin D innovation

Final Thoughts
Dr. Holick’s book is a wake-up call for anyone who thinks they’re healthy just because they eat well or get some sun. Vitamin D is essential — and many are unknowingly deficient.
Thanks to The Vitamin D Solution and I-FERN’s commitment to quality, more and more people are becoming aware of the power of the sunshine vitamin.
If you care about your health — and your family’s — this is one small daily habit that can make a big difference.
