The Vitamins That Start Absorbing in Your Mouth — and Why That’s a Good Thing
When most people take vitamins, they think of swallowing a pill and letting the body do the rest. But did you know that certain vitamins can actually start absorbing right in your mouth? Specifically, under the tongue (sublingual) or inside the cheek (buccal), where thin mucous membranes and rich blood vessels allow for direct access to the bloodstream. This method of absorption can be faster, more efficient, and ideal for people with digestive or absorption challenges. This is just one of the reasons Vitaminis juice shots are superior. The vitamins hit your system the second you sip. Vitaminis: Drink Your Vitamins.
Here’s a closer look at which vitamins can begin absorption in the mouth—and why that’s a smart option for some people.
1. Vitamin B12
Vitamin B12 is the classic example of a nutrient that benefits from sublingual delivery. B12 absorption in the gut relies on a protein called intrinsic factor, which many people—especially older adults or those with digestive conditions—don’t produce in sufficient amounts. Sublingual B12 tablets or sprays bypass this barrier, delivering the vitamin directly into the bloodstream for more reliable absorption. This is especially helpful for individuals with fatigue, neurological symptoms, or vegan diets.
2. Folic Acid / Folate (Vitamin B9)
Folate the synthetic form of folate, is essential for DNA synthesis, red blood cell production, and prenatal health. While typically absorbed in the small intestine, sublingual folate can begin absorbing through the mucosal tissue in the mouth, offering a faster and potentially more effective option—particularly for those with gastrointestinal conditions or folate metabolism issues such as MTHFR gene variants. Vitaminis Daily Greens has as much Folate as 2 cups of spinach!
3. Magnesium
Magnesium supports everything from muscle function to mood and sleep, but many oral magnesium supplements can cause digestive side effects like diarrhea or cramping. Sublingual magnesium lozenges or sprays offer an alternative by allowing some magnesium to be absorbed through the mouth’s mucous membranes, helping to deliver calming effects more quickly—and without upsetting your stomach. Vitaminis Immune Support has as much Magnesium as 4 cups of spinach.
4. Zinc
Zinc is vital for immune support, wound healing, and hormone function, but it’s another mineral known to cause nausea when taken in pill form. Zinc lozenges and sublingual sprays allow for partial absorption through the mouth, reducing reliance on the digestive tract and minimizing stomach discomfort. These forms are also commonly used during colds or viral infections, delivering zinc directly to the throat, where it may help inhibit viral activity. Vitaminis Immune Support has as much Zinc as 4 avocados.
5. Vitamin C
Vitamin C is a powerful antioxidant and immune supporter. While it's typically absorbed in the small intestine, liposomal, lozenge, or sublingual forms can begin partial absorption in the mouth. This may allow for faster systemic delivery and can be easier on the stomach—especially when high doses are needed for immune support or recovery. Vitaminis Immune Support has as much Vitamin C as 3 oranges!
Why Mouth Absorption Matters
-
Faster uptake: Bypasses the liver’s first-pass metabolism and allows nutrients to enter the bloodstream more quickly.
-
Gentler experience: Ideal for those with nausea, reflux, or pill fatigue.
-
Better absorption: Especially important for people with low stomach acid, gut inflammation, or conditions that impair nutrient uptake.
In Summary
If you experience nausea from vitamins, have gut issues, or simply want more efficient absorption, consider switching to sublingual or buccal forms of nutrients like B12, folic acid, magnesium, zinc, and vitamin C. Vitaminis liquid formats support better tolerance, faster results, and more reliable benefits—starting right in your mouth. Vitaminis: Drink Your Vitamins.
