BioActive Vitamin B12 5000 mcg | 3 BioActive Forms Plus Methylfolate Cofactor - Methylcobalamin, Adenosyl & Hydroxy | Sublingual Liquid Drops, Berry Flavor, Organic, Non-GMO, Vegan (1 oz)

Tastes fine. Highly recommended for those with a MTHFR gene mutation. I take it daily. If I miss a few days, I feel it. I trust and respect the manufacturer; they are known for good products. (No, I have no financial ties to them! I am just a satisfied customer who uses several of their products!)

Tastes a bit mediciny but what can you do. I've been taking it every day and washing it down with water anyhow since its good for me apparently (hopefully)

So far very pleased. Arrived well packed and unbroken. Pleasant taste, not bitter or medicinal. If I hold it under tongue and then swish around mouth at end seems to be little to swallow. Doesn’t stain teeth. Seems to have helped with fatigue. I usually take nap after lunch bcuz I am tired but last few days have more energy. Might rest and read for while but don’t nap which helps sleeping at night. I ordered some for my daughter who has job and is mom/wife and always seems to feel tired. Hope it helps her too.

Excellent service! Not bad tasting!

Very high quality methylated B12 complex. The price is good, and this gives me nice even energy. I really like how well it works!

It works as described.

I will start by saying at first I was impressed with this product—it has extremely high levels of three different types of B12 and it tasted great... in the beginning. Because it's so high in B12, I only took a drop or two; sometimes going days without use. About 1–2 weeks after opening, I noticed the taste changed a bit—I thought I was imagining things or maybe I had a bad taste in my mouth. It got worse—I thought it smelled a bit rancid, and checked the ingredients... sure enough, there's oil. I thought to myself how can it be rancid? It's best by date is 10/2025! I put it back and then checked it a few days later, this time actually tasting it—it was awful and it's most definitely rancid. I mean, I have oil oil sitting on my counter that's been open for a year... NOT RANCID. I think back and can't believe I talked myself out of believing it actually went bad that quickly. I cook a lot; I know what rancid oil smells like. Being the procrastinator that I am, I waited to inquire about a replacement or refund. With that being said, I did initiate a request within the refund period, but because it had been opened and used, I was directed to their website—a website, than explicitly states in no uncertain terms that a "customer service rep will respond within 24 hours, Monday through Friday, 8am-4pm EST." Yes, that is a direct quote. I know you can guess where this is going. That's right... no response! So, my only conclusion is that this seemingly reputable company is just the opposite of "Quality & integrity without compromise." I will give them props for one thing—their unwavering commitment to the timeless art of supplement seduction: Pretty packaging; impressive ingredients; false promises. This is the customer service of today, folks. Add to cart at your own risk—you’ve been warned.

Fast clean delivery. After researching B vitamins I learned that the cheaper ones did very little to support your immune system. I am pleased with this liquid form that has three types of B vitamin and I do feel more energetic after taking this type and brand.
