I've read some of the 1 start reviews claiming it's just coloured water - is it?

Vitamin B12 does not taste of anything. People are used to taking vitamins that taste of berries or cherries or are sweetened. They are tasting the additives in other products. We don't add anything, Bioactive B12 is just pure Vitmain B12.

How is the product preserved if you don't add any preservatives?

We protect our products using Miron violet glass, which blocks harmful light but allows beneficial violet, UVA, and infrared rays. This unique light filtration slows decay, enhancing the longevity and potency of Bioactive B12 without preservatives.

How quickly can I expect to see results from Bioactive B12?

While individual results vary, many people have commented on improvements in their energy levels in a very short space of time. If you are suffering from the effects of a B12 deficiency, it's very safe to take a therapeutic dose to begin with.

3000mcg seems quite high compared to the recommended daily amount, why is this?

The recommended amount is extremely low. Vitamin B12 is an incredibly safe vitamin with no upper toxicity level set, so there's no risk and you cannot over-supplement with Vitamin B12, especially if you have a known B12 deficiency.

Amazing for sleep problems!

Amazing!! I have struggled to sleep more than 4 hours a night for years, since menopause. From day one taking this as soon as I wake up.. I am sleeping all night. If I wake up to use the toilet I go straight back to sleep. The only negative experience is a bit of sluggishness when I wake up, apparantly caused by my body trying to make up for years of poor sleep. Otherwise my energy levels in the day have improved and I'm not falling asleep mid afternoon. I take half a dropper under my tongue as soon as I wake up. I don't drink or eat for half an hour after. I'm also beginning to notice my focus and concentration are improving slightly after one week. From childhood Ive been hyperactive and struggled with focus and lack of concentration. Ive tried all manner of supplements and nothing has ever worked before. I just bought this for sleep problems and it seems to be an all round miracle supplement i absolutely recommend this 100%. I have researched and found it also helps with symptoms of ADHD!

B12 Liquid

I’ve had a really positive experience using B12 liquid drops. They’re easy to take, taste pleasant, and fit seamlessly into my daily routine. I especially like the liquid form, as it feels more convenient than tablets and absorbs quickly without any hassle. Since adding these drops to my routine, I’ve felt more consistent in my daily energy and overall wellbeing. The dropper makes it simple to measure the right amount, and the bottle lasts a good while, which makes it great value for money. Overall, B12 liquid drops are a high‑quality, convenient supplement that I’d happily recommend to anyone looking for an easy and effective way to support their daily nutrition.

Finding Myself Again

WoW, I had forgotten what it felt like to have energy. After a recent blood test, it came back that my B12 was low. Did some research and found this product and since the reviews were so good I decided to give it a go. I'm certain the effects have been immediate! I've only been on it a week and my energy levels are so much more sustained throughout the day. Honestly I'm so happy. Thank you Nature Provides (added bonus It's a UK company!).
