Active Vitamin D3

The dirty little secret of the supplement industry is that traditional Vitamin D pills are pretty scary. Made with an animal by-product called “sheep grease”, most also lack the added Vitamin K2 you need to direct calcium into your bones instead of your arteries.

Smarter Vitamin D with Active Vitamin D3 from plants and with Vitamin K2 support is different. It can quickly and safely get your Vitamin D levels back to where they should be. It’s your best protection this season!

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

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!

Unlike other immune support nutrients like Vitamin C, it’s nearly impossible to get the 5,000 IU 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 in the Winter, unless you 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.

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

Here’s what you DON’T want in
your Vitamin D supplement

Yet it’s what you typically find in stores or online

Gross Animal Byproducts

Most vitamin D supplements are derived from bodily fluids secreted by sheep’s glands. Yes, it’s gross and not what you want to be putting into your body.


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 marketers because it’s so much easier to come by.


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


Chemicals like magnesium stearate and stearic acid, which are neither necessary nor beneficial to your health, are added to cheap vitamin D supplements in stores.

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 pills that are derived from secretions of sheep's glands, then chemically processed, Smarter Nutrition’s Vitamin D3 comes from the most premium plant source of active Vitamin D3. It’s sustainably sourced from a nutrient-rich green plant called a lichen — a vitamin D3 source that’s naturally free from contaminants and undesirable animal byproducts.
Essential Vitamin K2 Complex Support evidence shows that vitamin D is dependent on vitamin K2, and that vitamin D toxicity can actually be caused by the lack of vitamin K2. In addition to being a necessary ingredient for protection, the benefits of vitamin D3 are greatly enhanced by vitamin K2 in terms of bone strength, cardiovascular health, and more.
Perfect Formula — Synergy of Four Natural Ingredients Smarter Nutrition Vitamin D3 is encapsulated in vegetarian softgels with organic extra virgin coconut oil for faster 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.

Frequently Asked Questions
What does vitamin D3 do?

Vitamin D3 is a fat-soluble nutrient that affects as many as 2,000 genes in your body. It has many important functions, but one of the most vital is calcium absorption to maintain healthy bones and teeth. Other functions that vitamin D3 supports include:

  • Immune system health
  • Muscle function
  • Cardiovascular function
  • Respiratory system health
  • Brain health
  • Mental wellbeing

There are two types of vitamin D: vitamin D3 (cholecalciferol) and vitamin D2. Vitamin D3 is the fully activated form that is identical to vitamin D produced in the body by exposure to sunlight. Vitamin D3 is highly bioavailable and considered superior to other forms of vitamin D.

Vitamin D2, on the other hand, is not readily bioavailable. In fact, a report published in The American Journal of Nutrition states that “vitamin D2 should not be regarded as a nutrient suitable for supplementation or fortification.

Smarter Vitamin D3 is unlike other vitamin D products. It contains the superior, fully activated form (cholecalciferol), and is uniquely derived from a plant source called lichens. Smarter Vitamin D3 is vegetarian, all natural, and suitable for any diet or lifestyle.

Most vitamin D supplements marketed as “vegan” are derived from irradiated mushrooms, and they are vitamin D2, the inactive form that research shows to be less bioavailable than vitamin D3.

The vast majority of vitamin D3 supplements are derived from bodily fluids secreted through the sebaceous glands of sheep, and are not suitable for vegans or vegetarians. Smarter Vitamin D3 is made from plants, not from animal byproducts.

The main reasons most supplement companies do not use plant-based vitamin D3 are: cost and scale. Vitamin D3 from lichens costs significantly more to grow and produce compared to the low cost of sheep-sourced vitamin D3. The vitamin market is huge, so it would not be of interest economically for most brands to offer their customers a superior product if it results in significantly lower profits.

In short, yes. Most vitamin D3 supplements are single-ingredient products designed to help increase calcium absorption in the body. However, when taking vitamin D3 on its own, there is a risk that excess calcium can be improperly distributed to joints and arteries, where it has the potential to calcify and cause disease.

Smarter Vitamin D3 doesn’t just increase calcium absorption, our D3 supplement is formulated with essential vitamin K2 and supporting ingredients that work synergistically with your body to regulate calcium levels and protect joints and arteries.

Smarter Nutrition has utilized the latest scientific research to create a formula that combines the optimal amount of Vitamin D3 with an essential vitamin K2 complex for protection.

While vitamin D3 works to pull calcium into the bloodstream, vitamin K2 is what directs calcium into the bones and away from joints and arteries. Without vitamin K2, there is the risk for calcification. For healthy calcium absorption vitamin D3 simply must be balanced by a proper amount of vitamin K2.

Vitamin D3 (plant based, vegetarian) — Sustainably sourced from lichens, this activated form of vitamin D is highly bioavailable and identical to what your body produces when exposed to UV sunlight. Unlike most supplements, our vitamin D3 is made from plants, not animal byproducts.

Vitamin K2 complex (menaquinone-4, menaquinone-7) — Without vitamin K2, the calcium absorbed by vitamin D3 can build up in your joints and arteries. Vitamin D3 simply must be balanced with a high-quality K2 complex.

Organic extra virgin coconut oil — Medium chain triglycerides (MCTs) in coconut oil provide quick energy for the body and enable fast absorption of fat-soluble vitamin D3 and vitamin K2.

Tapioca — Our vegetarian softgels are made from tapioca, a starch extracted from the cassava root. Naturally high in iron and gluten-free, tapioca is a premium alternative to animal-derived softgels and leaky capsules.

Organic glycerin — Tapioca is mixed with purified water and organic glycerin to make a healthier softgel that’s convenient and easy to swallow.

Turmeric — Derived from the roots of Curcuma longa, turmeric gives Smarter Nutrition Vitamin D3 softgels their naturally bright yellow color.

Sunflower lecithin (non-GMO) — A rich phospholipid and potent antioxidant, sunflower lecithin acts as an emulsifier to keep vitamins D3 and K2 stable.

Even people with low levels of vitamin D may be asymptomatic for long periods of time. The most common symptoms include:

  • Fatigue
  • Muscle pain or weakness
  • Joint pain
  • Weight gain
  • High blood pressure
  • Restless sleep
  • Poor concentration
  • Headaches
  • Bladder problems
  • Constipation or diarrhea

Our suggested dose to start is 5,000 IU (2 softgels) per day, and is based on recent studies which show that for people deficient in vitamin D, doses of 5,000 IU for 3 months were more effective than lower doses for returning blood serum concentrations to optimal levels.

Each softgel is 2,500 IU and 1 softgel would be considered an appropriate dose for maintenance. We realize that many people may be seeking higher doses of Vitamin D3 than suggested here. Always consult your health provider if you are considering taking a higher dose.

As always, please consult with your healthcare provider.
