    Great supplement!

    I love these B12 sublingual drops! So many sublingual drops have cinnamon in them & I’m allergic to cinnamon.
    Have to take sublingual. These are great, no taste, no cinnamon. Also feel wonderful, can tell a difference if I forget to take them for a few days. B12 levels now in normal range, yay!

    Best B-12

    I was previously taking another brand of sublingual B vitamin. While I did feel better when taking it, I always wondered if it was the correct formula for me. I did a bunch of research on B-12 and then searched for a product that matched what I felt I needed. This was the only product out there with exactly what I wanted. This B-12 is great and I notice a big difference if I miss a day. It helps with my overall energy level and frame of mind. It's easy to take and tastes good. Thank you for such a clean B-12 formula!

    Great product

    B12 is one of those things where you only know it is or isn’t working after you have been without it for awhile. Prior to ordering this product I had been without methylcobalamin sublingual B12 for a few months and the grocery store tablets and gummies just weren’t delivering enough punch. I went online and learned about the additional forms of B12 and found this product. I am always a bit reluctant to try something new. I am a very cautious person, more so when dealing with my health. However, the fatigue was settling in with the depression caused by COVID-19 isolation and oppression and I decided that those factors were more of a risk than the unknown of the new formula. I can honestly say that I felt improvement within a few days. The fatigue lifted and my mood improved. Like everyone, I continue to battle the isolation and oppression of the Covid-19 restrictions on life. Having this product to relieve the fatigue from B12 deficiency (which I believe is Hashimoto related) has definitely made the battle more bearable. Ordering my second 90 day supply.

    Very pleased with Pure Products!

    We’ve tried many liquid vitamin B products after years of tablet ingestion. Pure’s BioActive B12 is the sublingual vitamin B solution we have been searching for, for many years. The taste is perfect, we’ve noticed improvements in our energy in that we are much less fatigued following a day of activity. Lastly, the Pure process of product creation comforts us in that ingredients do not include harmful traces of cyanide found in many other Vitamin B supplements. Thank you Pure for caring about your customers.

  • More Details
    • 3-IN-1-SUPPORT: BioActive B12 "Full Spectrum" - is a high quality VEGAN vitamin B12 complex utilizing three bioavailable forms. This advanced formula includes ingredient forms that need no conversion in the liver in order to be available for use by your cells. As a sublingual supplement, BioActive B12 provides maximum absorption through the mucous membranes in the mouth. It has a natural and mild taste that is easy on the palate. China Free - Alcohol Free - Non GMO - Sugar Free - Unflavored
    • METHYLCOBALAMIN -- Biologically Active Form: Utilizing patented *MecobalActive* with exceptional purity; no harmful solvents are used in its production as you see with many other methylcobalamin supplements on the market.
    • ADENOSYLCOBALAMIN -- Mitochondrial Form: Considered an active "coenzyme" form of B12 and is utilized directly in B12-dependent enzyme reactions in the body.*
    • HYDROXOCOBALAMIN -- Protector Form: Readily converts to methylcobalamin and has a unique role in supporting detoxification processes.*

    From our blood cells to our nerves and down to our DNA, Vitamin B12 is a critical vitamin for the health of our bodies. We've carefully formulated this highly bioavailable Vegan BioActive B12 to include ALL 3 bio-available forms of B12. Bioactive simply means that the B12 has already been converted into a form that your body can utilize immediately.  With these specialized bioactive forms, the B12 does not need to be converted in order to be available for use by your cells (conversion can be especially problematic for people with MTR, MTRR, COMT as well as other gene defects).

    Did you know that both vegan and non-vegan individuals suffer from B12 deficiency? If you’re omnivorous, you may get some B12 from meats, dairy and eggs; however vegetarians and vegans have a more difficult time. If you’re a strict vegan, studies have confirmed that you’re likely to be deficient in B12, unless you’re supplementing regularly. While rates of B12 deficiency are much higher in vegetarians and vegans than in omnivores, that doesn’t mean it’s rare in omnivores. Approximately 1 in 20 omnivores are B12 deficient. B12 deficiency is also more common in people with gut problems since that may decrease intestinal absorption (including taking OTC drugs which block stomach acid). Older adults are also at risk as stomach acid levels decline as we age, which makes it difficult to cleave the vitamin from its protein bound form in food.

    The consequences of vitamin B12 deficiency are extremely serious and sometimes irreversible  (nerve damage for example). B12 is water soluble - our bodies are unable to store it for very long. Ultimately, it's very important that you are getting enough B12 in your diet - and the easiest, most bio-available method is to take this supplement consistently.

    Methylcobalamin - Assists methylation, brain & nerve health, circulatory & immune systems, reducing homocysteine.*

    Adenosylcobalamin - Aids in muscle recovery, mitochondrial support, repairing the myelin sheath.*

    Hydroxycobalamin is a precursor form of vitamin B12 converted in the body to both methylcobalamin and adenosylcobalamin. This form of B12 helps in pain sensitivity, chronic fatigue, brain fog and detoxification.*

    MONEY BACK GUARANTEE - 100% RISK FREE - If our BioActive B12 Full Spectrum isn't the best supplement you've ever tried, simply return the bottle within 30 days of purchase (even if empty). You'll receive 100% refund of your purchase price. It's that simple!

    Manufactured in the USA in a GMP-certified facility, for guaranteed quality and potency. This supplement is third party tested to ensure the highest quality, potency and purity of each batch.

  • I don’t see fillers in the supplement ingredients, how is that possible?

    As the name of our company indicates, we believe in creating the most PURE supplements on the market. We take these supplements ourselves and only accept the best in terms of raw material, quality and manufacturing. Most supplement companies utilize fillers, excipients and harmful additives in the name of profit.

We do not believe in using fillers – our supplements contain only the stated active ingredients with associated health benefits. We also utilize small batch manufacturing, so speed through a machine is not a requirement or issue. Our priority is to deliver the most pure, trustworthy and effective supplements available at an affordable price.

    We manufacture our own supplements which are formulated under strict guidance in a US based, GMP certified, FDA inspected facility.
