BEST VITAMIN D3

Product Overview

According to a recent study, as many as 75% of Americans are deficient in Vitamin D -- a Vitamin essential in promoting healthy bones and muscles, mood, energy, cardiovascular health, and supporting your immune system.

In order to get enough Vitamin D through the synthesis of Vitamin D3 in your skin from sunlight, The Vitamin D Council recommends up to 2 hours a day for a person with dark skin. Yes, you read that correctly.

For those of us who have sh#t to do, we’ve developed our new Vitamin D3 liquid capsules with added Coconut Oil and Bioperine. Often referred to as the sunshine vitamin, our Vitamin D3 capsules are in the same bioavailable form of Vitamin D that is naturally produced by your body when exposed to sunlight.

Unlike other Vitamin D supplements, our capsules contain zero preservatives and zero lactose -- making it the perfect choice for athletes looking for a clean source of D3. In addition, the combination of added Coconut Oil and Bioperine help increase the bioavailability and absorption of this fat-soluble vitamin to ensure you’re not flushing money down the drain.

FEATURES
5000 IU of Vitamin D3
500mg of Coconut Oil to Boost Absorption
5mg of BioPerine to Boost Absorption
Promotes healthy bones & muscles
Supports immune system, & cardiovascular health
Boosts mood

FAQ

Vitamin D3, also known as cholecalciferol, is your bodies preferred form of Vitamin D found in oily seafood, egg yolks, butter, and dairy. The interaction with ultraviolet B radiation from the sun catalyzes the synthesis of vitamin D3 in the skin. Vitamin D2, known chemically as ergocalciferol, is derived from plants. Whereas our skin produces vitamin D3, the skin of fungi and plants produce vitamin D2. Notably, humans do not naturally produce vitamin D2, making vitamin D3 the more bioavailable and natural type.

We have a blog post here that breaks it down, but here are the top three reasons: Vitamin D3 is better at raising Vitamin D levels in the blood. Vitamin D3 lasts longer in the blood than Vitamin D2. And finally, Vitamin D3 has a longer shelf life in general.

We decided upon the 5000IU option because it will get at least 97% of the population to above 30ng/ml of Vitamin D and not cause any toxicity issues. Here's a link to a study showing the amount of D3 needed in order to obtain a Vitamin D level of 40ng/ml. 10,000IU is generally recognized as the safe upper limit for adults by The Endocrine Society.

Feeling a lot better than last winter when I was taking a D supplement from another company.

I have two of these, this is my first time taking vitamin D3, I like that the pill is very small, and the contents in it look so cool. I don't know where else to get vitamin D3 in food, so it's cool to take this.

ATH

We're here for you Andrea!
