Premium Vitamin D3 in Sunflower Oil for Maximum Absorption

5000 IUs of D3 for Strong Immunity, Healthy Bones and Good Sleep

If there is one Vitamin to rule them all–look no further than Vitamin D. Receptors for this “sunshine vitamin” are found virtually everywhere in the body.1 Vitamin D has been shown to play a critical role in supporting overall health, including immunity,2 bone health 3,4 and mood.5 If you live in the US or Canada, it’s likely that you aren’t getting enough Vitamin D from its primary natural source: sun exposure. Research shows 6 upwards of 40% of the population has a deficiency.

During winter months far from the equator, there’s not enough UVB radiation from the sun to stimulate adequate production of Vitamin D on the skin. Latitudes that include New York City and Boston are Vitamin D dead zones from November to March.7,8 During summer months, sunscreen use curtails the skin’s ability to make Vitamin D. Unless you plan to eat a plate of fish bones every day, it’s darn difficult to improve your Vitamin D levels from food.9

Supplementing with Nested Naturals Vitamin D3 is a potent, cruelty-free and easy way to increase your levels of this critical vitamin. Each capsule gives you 5,000 IUs of premium quality, highly absorbable Vitamin D3 sourced from purified lanolin. We designed our gel-caps to be small and easy to swallow. As importantly, there’s no gnarly aftertaste that is common with other Vitamin D3 supplements.

100% Pure Sunshine in a Bottle

Promote Strong Bones and Healthy Teeth

Vitamin D helps the body absorb and use minerals such as calcium and phosphorus which are necessary for strong bones 3,4 and healthy teeth.10 Without enough Vitamin D, bones and teeth begin to weaken which can result in fractures and bone loss.11

Reproductive Health

Vitamin D is thought to play a role in reproductive health for both men and women. It appears to play a role in ovary regulation.15 Clinical studies 16 show higher Vitamin D levels in women with successful IVF treatment while the quality and motility of sperm has been correlated with higher Vitamin D levels in men. 17

Sleep Quality

Vitamin D appears to be a big missing link to healthy sleep. Recent clinical studies 19,20 suggest that Vitamin D plays a role in sleep regulation, quality and duration. Low Vitamin D levels have also been linked to sleep apnea.21

Strengthen Immunity

Adequate Vitamin D levels are important for immune regulation and studies 12,13 suggest that it can help keep colds and flus at bay. Over the long term, research also suggests that Vitamin D may protect against autoimmune diseases such as Multiple Sclerosis and Crohn’s disease.14

Improve Mood, Sleep and Energy

Studies5,18 have found a positive correlation between healthy Vitamin D levels and both mood, sleep quality and energy levels.

Support Wellness

Research suggests that Vitamin D can help lower blood pressure, aid in blood sugar control, improve cognition and even increase testosterone.22,23

Your Questions, Our Answers

See the most popular questions asked about Vitamin D3.

What’s the difference between Vitamin D3 and D2?

Vitamin D supplements come in two types: D3 or D2. Vitamin D3 (a.k.a. cholecalciferol) is extracted primarily from either purified lanolin harvested from sheep’s wool or fish oil. Vitamin D2 (a.k.a. ergocalciferol) is synthesized from plant materials.

Studies show 24 that D3 is more effective than D2 at sustaining levels of Vitamin D in the body. Vitamin D3 is the form that our skin makes naturally when exposed to the sun.

Should I take Nested Naturals Vitamin D3 with food or on an empty stomach?

Vitamin D3 a fat-soluble; it needs fat to be absorbed. That’s why we combine it with sunflower oil in the gel-cap. You can take Nested Naturals Vitamin D3 on an empty stomach, but it wouldn’t hurt to take it with a meal.

Where is Nested Naturals Vitamin D3 sourced?

We are relentless about sourcing the best, most natural, most ethically produced ingredients available. While other brands cut corners by using low quality D3 from China, ours is from a premium source in the United States.

Is Nested Naturals Vitamin D3 vegan?

Although Nested Naturals Vitamin D3 is vegetarian, it isn’t vegan. There are two main sources of Vitamin D3: fish oil and purified lanolin harvested from sheep’s wool. Nested Naturals Vitamin D3 is made from purified lanolin, which we believe is the more animal-friendly choice. No animals are killed to produce this supplement. We’ve added a sunflower oil carrier to help your body absorb the Vitamin D3 more efficiently.

What is corn starch doing in Nested Naturals Vitamin D3?

This natural starch product derived from the corn kernel is used in tiny amounts to produce our softgel. It is a fine white to yellow powder commonly used in the manufacturing of nutraceuticals and pharmaceuticals as a disintegrant and binder. Disintegrants allow softgels to break down into smaller fragments so that the beneficial natural ingredients can be released for absorption by the body.

The amount of corn starch used in the softgel are insignificant and should not have an affect on your health.

What is carrageenan and what is it doing in Nested Naturals Vitamin D3?

We include tiny amounts of carrageenan in our softgel. Carrageenan is derived from algae that we use to help thicken the compound and create a homogenous solution while in our high quality nutraceutical mixer. Not only that, but carrageenan is one of the best vegan options as a substitute for animal-based gelatin, allowing us to make our capsule out of purely vegan ingredients.

There are various forms of carrageenan, and it has over 50 years of safe use. In fact, It was originally used in Ireland around 1810 to cure respiratory ailments and since has been used as a food additive. We use a food grade carrageenan that has been carefully reviewed and found to be safe by the European Commission and the World Health Organization.

Should I be taking Vitamin K with my Vitamin D3?

One of the major roles of Vitamin D3 is to help the body extract calcium from the food we eat. High doses of Vitamin D3 mean the body absorbs lots of calcium which can be great for bone health. However, the bones need adequate levels of Vitamin K2 to make use of the available calcium.25 If you don’t get enough K2, unused calcium builds up in the arteries which can lead to cardiovascular disease.26 Our Vitamin D3 includes 5,000 IUs for optimal immunity, bone health and sleep. For optimal cardiovascular health, we’ve formulated it to pair with our Vitamin K2 made from non-GMO chickpeas.
