Active Vitamin D3

The dirty little secret of the supplement industry is that traditional vitamin D pills are made with an animal byproduct called “sheep lanolin.” Most also lack the vitamin K2 you need to direct calcium into your bones and not your arteries.

Smarter Vitamin D with “Active Vitamin D3” from plants and Vitamin K2 support is different. It provides bioavailable vitamin D to encourage the restoration of optimum levels and promote immune system health!*

Why Do I Need
5,000 IU of Vitamin D
Every Day?

Unlike other immune support nutrients, like vitamin C, it’s nearly impossible to get the amount of vitamin D you need each day from food. You can bring your vitamin D levels up with repeated sun exposure, but that’s not possible for most people in the winter unless you happen to live in the Caribbean.

Having healthy vitamin D levels does more than support a healthy immune system: It also directly affects the health and expression of more than 2000 genes in your body, which influence:

The Fall and Winter, the peak of cold and flu season, is when 90% of Americans are deficient in Vitamin D — leading to weakened immune systems. Bad timing!

If you’re taking a stand-alone traditional Vitamin D supplement, you could be doing more harm than good!

Most vitamin D supplements are derived from fluids secreted by sheep’s glands. While it is a time-tested source of vitamin D, it doesn’t fit every diet or lifestyle.


Vitamin D3 is the active form of Vitamin D that’s easily absorbed by the body and mimics what you get from natural sunlight. Vitamin D2 is used by some manufacturers because it’s so much easier to come by.


Stand-alone vitamin D supplements, without added Vitamin K2, can cause calcium buildup in parts of the body like the arteries, which can lead to health risks and disease.


Additives like magnesium stearate and stearic acid are sometimes added to lower the cost of producing vitamin D supplements in tablet form. They’re neither necessary nor beneficial to your health.


SMARTER NUTRITION has pioneered the clean and active Vitamin D3 supplement that big-name store brands SHOULD be selling!

Premium Plant-Based Vitamin D3 — The Most Absorbable and Active Form

Unlike other Vitamin D supplements that contain processed animal by-products, Smarter Nutrition’s Vitamin D3 comes from the most premium plant source of active Vitamin D3. It’s sustainably sourced from a nutrient-rich organism called lichen — a vitamin D3 source that’s naturally free from contaminants and animal-derived ingredients.


Essential Vitamin K2 Complex

Vitamin D has a dependent relationship with vitamin K2, and vitamin D toxicity can actually be caused by a deficiency in vitamin K2. The benefits of vitamin D3 are greatly enhanced by the presence of vitamin K2 in terms of bone strength, cardiovascular health, and more.

Synergistic Formula

Smarter Nutrition Vitamin D3 is encapsulated in vegetarian softgels with organic extra virgin coconut oil for greater bioavailability than powdered products. The medium chain triglycerides (MCTs) in coconut oil provide quick energy for the body and enable fast absorption of the fat-soluble vitamins D3 and K2.* It’s the optimal blend of ingredients for safety and maximum benefits!

Fully Bioavailable

Using cutting-edge technology, Smarter Nutrition Vitamin D3 is encapsulated in vegetarian softgels that are free from chemical coatings, fillers, and synthetic binders. We deliver premium, plant-based vitamins D3 and K2 in coconut oil to make Smarter Vitamin D3 as bioavailable as possible.
