We AVOID These Common Ingredients in Our Liquid D3:
Bulking Agents & Anti-Caking Agents (e.g., Magnesium Stearate):
Used to speed up production volume but offer no nutritional value and can lead to digestive issues. We skip unnecessary fillers to keep our product clean¹, ².
D3 is a Fat-Soluble Vitamin:
Vitamin D3 is fat-soluble, meaning it requires fats to be absorbed effectively by the body. This is why Vivo Life D3 is blended with MCT (coconut oil), ensuring optimal absorption and bioavailability. Research shows that pairing D3 with healthy fats enhances its effectiveness³.
Animal-Derived D3:
Animal-derived D3, like that sourced from sheep’s wool (lanolin), is less sustainable. We use plant-based D3 derived from sustainable pine, which is equally effective and more ethical⁴.
Third-Party Lab Testing:
While many other brands skip third-party testing because it's not required by law. We rigorously test both our ingredients and final formulas for heavy metals, pesticides, and contaminants, giving you confidence that what you're putting in your body is clean and trustworthy⁵.
We back up our claims with full nutritional analyses on every product, ensuring you can trust what you're putting in your body.

D3 contributes to the normal function of your immune system—and the science proves it.
A large study involving over 11,000 participants, led by Harvard researchers, revealed that Vitamin D helps protect against colds and flu.²
Regular supplementation significantly reduces the risk, especially for those with low Vitamin D levels. Daily or weekly doses of D3 were found to be the most effective way to keep your immune system functioning normally.²

The amount of D3 you need can vary from person to person—because let’s face it, we’re all a little different! Some of us just need a bit more sunshine (or supplements) to keep our glow.
Here’s what you need to know to make the best judgment:
Sunlight is Key:
Your skin can produce 4,000 to 10,000 IU of Vitamin D3 in just 10-30 minutes of sun exposure¹. However, if you’re spending more time indoors or live in an area with limited sunlight, you’ll likely need to supplement.
Current Guidelines Are Too Low:
The current recommended daily intake of 400-800 IU is considered too low by many experts. Studies suggest that to reach optimal levels of 25-hydroxy-vitamin D (the form your body uses), you likely need 1.5-6 times more than the current guidelines, which translates to around 2,000 IU per day for adults²,³.
Higher Doses Are Safe:
Research shows that even at doses of 2,000 IU daily, there’s no risk of oversupply, and some people may even need more to achieve optimal levels. Studies have shown that individuals taking 2,000 IU per day do not exceed safe levels, even with adequate sun exposure⁴.
Personalized Doses:
For the most accurate advice, it’s always a good idea to consult a health professional. A blood test is the best way to monitor your Vitamin D levels and adjust your intake accordingly. A more personalized approach recommends 40-60 IU of Vitamin D per kilogram of body weight. So, for a 60 kg (132 lb) person, that would be 2,400-3,600 IU per day⁵.

Vitamin D3 is well known for it's health benefits, but many people often forget that these health benefits are enhanced when D3 is combined with K2.
For example, vitamin D3 and K2 are both essential for calcium absorption in the bone. Vitamin D3 increases absorption whilst K2 activates a protein called osteocalcin, which integrates the calcium into the bone.
Without these two nutrients, calcium cannot do it's job effectively.

Our bodies rely on sunlight to produce Vitamin D, but if you’re spending more time indoors or not getting enough sun, it’s easy to become deficient.
Often called the 'sunshine vitamin,' Vitamin D3 plays a crucial role in regulating serotonin—the 'feel-good' chemical in our brain and contributing to your immune system².
A large study looking at 14 different pieces of research with over 31,000 participants found a strong link between low Vitamin D levels and depression. It suggests that not getting enough Vitamin D may affect your mood and energy.³
