Tulay's B12 Deal

You can check for sure with a blood test from your doctor. But keep in mind: Dutch "normal values" have been criticized for years, and many doctors consider the lower limit (148 pmol/L) too low. Lots of women only really feel good above 400 pmol/L. Do you recognize 3 or more symptoms from our symptom check? There's a good chance a deficiency is the cause. One strip a day is a safe, easy way to see if it makes a difference.

Give it 4-6 weeks. B12 replenishes a deficiency that may have built up over years, which doesn't fix itself in a week. Many customers notice the first signs after 2-3 weeks (less of an afternoon slump, clearer mood). People usually feel the real difference in weeks 4-6.

Sounds like a lot, but it isn't. B12 is water-soluble, so whatever your body doesn't need, you just pee out. No buildup, no toxicity. We purposefully use a high dose because even with sublingual absorption, your body only takes what it can use at that moment. For comparison: a doctor gives 1,000 to 2,000 mcg per injection.

A regular B12 pill has to go through your stomach acid and needs a protein (intrinsic factor) to be absorbed. For women on the pill, vegetarians, people taking acid reducers, and women around menopause, that protein doesn't work as well. A quick-dissolving strip goes straight into your bloodstream via the mucous membrane under your tongue. No stomach, no liver, no intrinsic factor needed.

Studies show that dissolving B12 under your tongue works just as well as injections—no needles, no appointments, and no doctor's visits needed. If you have serious absorption issues, injections might still be necessary, so check with your doctor. For most women with a mild to moderate deficiency, taking a strip every day is just as effective.

Morning is best. B12 supports your energy metabolism — which is what you want during the day, not right before bed. With or without food doesn't matter. One strip a day, whenever is easiest for you to remember.

Both work great. We use cyanocobalamin, the most thoroughly researched form of B12—the same one your doctor uses for injections. Studies show it absorbs and works just as well as methylcobalamin, sometimes even better. We go with what's clinically proven, not what's trending. (And before any wellness influencer claims we use cyanocobalamin because it's "cheaper" or "better": that's just a stubborn myth. The production costs are pretty much identical.)

Yes. Our B12 is fermentation-based, not from an animal source. The strip base is plant-based (pullulan), not gelatin. All flavors are natural and vegan.
