Key Benefits for
Vitamin-D
Immune Support

Vitamin D can support your immune system and may help it fight viruses. Studies show Vitamin D supplementation can help reduce the risk of viral infection, such as the flu or other respiratory infections.{3}

Bone and Arterial Health

Vitamin K acts like a “traffic cop” for calcium and directs the calcium where to go: it helps deposit it in bones and teeth, and away from undesirable destinations, such as building up in the joints, arteries, or forming stones in the kidneys.{4}

Mood Support

Studies show that Vitamin D deficiency is common in people with depression, anxiety and fibromyalgia. Supplementation with Vitamin D has been shown to improve symptoms.{5}

Dr. Nancy Rahnama, expert in obesity medicine and clinical nutrition, answers your frequently asked questions:

These are the main ingredients in Vitamin D:

  • Vitamin D-3
  • Vitamin K-1

This formula does not contain egg, gluten, yeast, synthetic dyes, artificial flavorings, and preservatives. Our capsules are made from vegetarian friendly plant-based cellulose.

Vitamin D is one of Dr Nancy’s Essentials. It's recommended for everyone, at any age or weight.

*All individuals are unique. Your results can and will vary. Consult with your health-care provider before beginning any new supplement.

Using Vitamin D is easy. Simply take 1 easy-to-swallow capsules each day.*

*Consult with your health-care provider before beginning any new supplement.

Vitamin D is an Essential supplement. Adding Complete Multi or Metabolic Multi, Omega Supreme and our Pre-Probiotic round out the essentials recommended for everyone.*

*Consult with your health-care provider before beginning any new supplement.

It’s best to take Vitamin D constantly on a daily basis. If you happen to miss a day, just continue with your regular dose the next day.

While many users feel a noticeable difference upon starting Vitamin D, some don’t and that’s okay too. It’s what’s happening inside your body that counts. The benefits you may feel are extra bonuses when it comes to improving your long-term health. Fat-soluble nutrients like Vitamin D-3 take time to be utilized by your body. Overall it can take 3-4 months to reach a new equilibrium in your body.

*All individuals are unique. Your results can and will vary.

We believe everyone can benefit from the ingredients in Vitamin D. However, I also know that every person is unique. As a physician, I recommend consulting with your own health-care provider before beginning any new supplement.
