Built With Evidence
Every Viven formula starts with a question: does the published research actually support this ingredient, this form, this dose? We work directly with a biochemistry professor at the Lithuanian University of Health Sciences to make sure the answer is yes before anything goes into a bottle.
Our Products
At Baltic latitudes, most of us don’t get enough sunlight for most of the year — which is exactly why Vitamin D is Europe’s most widely used supplement. We pair D3 with K2 in its well-absorbed MK-7 form. Vitamin D contributes to the normal function of the immune system and to the maintenance of normal bones; vitamin K contributes to the maintenance of normal bones.
Several zinc products on the market sit at or above the EU’s upper safety limit in a single dose. We use a well-absorbed bisglycinate form, dosed within EU guidelines. Zinc contributes to the normal function of the immune system and to the protection of cells from oxidative stress.
Most fish oil on the market is sold as an ethyl ester — the cheapest form to produce, and one of the least well absorbed. We use the re-esterified triglyceride (rTG) form instead, shown in published research to absorb meaningfully better. EPA and DHA contribute to the normal function of the heart; DHA contributes to the maintenance of normal brain function.
Much of the magnesium on Baltic shelves is bound to a form the body struggles to absorb — some products even declare yields that aren’t chemically possible. We use magnesium bisglycinate, a gently absorbed form. Magnesium contributes to the reduction of tiredness and fatigue and to normal muscle function.
"79% of the people we surveyed aren't sure whether the supplements they take are actually working."
