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! Review: An amazing product! - I have been taking this product for 6 months now and I feel great. Within the first week I noticed a difference in my energy levels. I feel clearer and more alert, improved memory and generally a healthier happier mood. After the birth of my 3rd baby 18 months ago I was feeling very depleted, physically exhausted running around after 3 small children and lacking strength, my muscles felt tired. Since taking this supplement (along with drinking celery juice for the last 3 weeks) I feel completely amazing. My strength is returning, i am generally more relaxed and the stress and exhaustion has left my body! Despite often having broken sleeps, being woken by the children, I have an energy and alertness to carry me through the day alongside a feeling of happiness, excitement and positivity. I can't recommend this product enough. It was delivered quickly and it super easy to take and tastes nice. My children like to have some when I do too. We are all vegetarian and while I try to get nutritional yeast Into our diet, I didn't realised how depleted of b12 I was, until I began taking this supplement. Oh one last thing to note, my digestive system feels healthier too. Very grateful, thank you. ## Features - Dual Bioactive B12 Formula: Each 1 ml daily dose (13 drops) delivers 3000 mcg of both Methylcobalamin and Adenosylcobalamin, the 2 active forms your body can utilise immediately without conversion; unlike single-form or cyanocobalamin products, this dual-form combination provides complete bioactive coverage; particularly suitable for those with MTHFR gene variations who may have difficulty converting standard B12 forms - Sublingual Liquid for Fast Absorption: Hold 13 drops (1 ml) under the tongue for 30 seconds to allow direct uptake into the bloodstream, bypassing digestive processing; the formula is almost tasteless with no aftertaste; if sublingual use is not preferred, the drops can also be swallowed or stirred into water, though sublingual delivery is specifically designed for optimal absorption results - Ultra-Pure 3-Ingredient Formula: Just 3 ingredients, Methylcobalamin, Adenosylcobalamin, and reverse osmosis water; no colours, flavourings, sugar, or preservatives; vegan-friendly and GMO-free by ingredient sourcing; contains no common allergens, though we always recommend checking the label if you have specific sensitivities; bottled in Miron UV-proof glass to protect potency; store in a cool, dry place away from direct sunlight - Quality Assured and Practitioner Guided: Every batch is manufactured in a GMP and ISO-accredited, FDA-registered UK facility compliant with HACCP, GFSI, and SALSA standards; B12 is a water-soluble vitamin, consult your healthcare practitioner to determine the right dose for your needs, especially if you are pregnant, breastfeeding, taking medication, or have a medical condition - Supports Your Daily Wellbeing: Vitamin B12 contributes to normal energy-yielding metabolism, the reduction of tiredness and fatigue, normal functioning of the nervous system, normal psychological function, normal red blood cell formation, and normal functioning of the immune system; each 50 ml bottle provides a 50-day supply at 1 ml per day; suitable for vegans, vegetarians, and adults seeking high-strength B12; take daily at the same time each day; individual results vary ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07H31BFRB | | Age Range Description | Adult | | Allergen Information | Contains: Egg Free, Gluten Free, Lactose Free, Peanut Free, Wheat Free | | Benefits | Digestive Health Support, Energy Management, Metabolism Improvement | | Best Sellers Rank | 1,747 in Health & Personal Care ( See Top 100 in Health & Personal Care ) 6 in Vitamin B12 | | Brand | Nature Provides | | Brand Name | Nature Provides | | Colour | Red | | Container Type | Bottle | | Country Of Origin | United Kingdom | | Customer Reviews | 4.5 out of 5 stars 3,031 Reviews | | Diet Type | Vegan | | Diet type | Vegan | | Dosage Form | Liquid | | Dose Release Method | Immediate Release | | Flavour | Unflavoured | | Item Dimensions | 40 x 40 x 140 millimetres | | Item Form | Liquid | | Item Weight | 165 Milligrams | | Item form | Liquid | | Manufacturer | Nature Provides | | Number of Items | 1 | | Primary Supplement Type | Vitamin B12 | | Primary supplement type | Vitamin B12 | | Product benefits | Digestive Health Support, Energy Management, Metabolism Improvement | | Special Ingredients | All Natural, no GMO, no preservatives or fillers, no added sugar, no gluten | | Specific Uses For Product | Energy, Liver, Nerve, Skin | | Unit Count | 50.0 millilitre | ## Product Details - **Brand:** Nature Provides - **Diet type:** Vegan - **Flavour:** Unflavoured - **Item form:** Liquid - **Primary supplement type:** Vitamin B12 ## Images ![Bioactive B12 - Image 1](https://m.media-amazon.com/images/I/81F+sPiA2fL.jpg) ![Bioactive B12 - Image 2](https://m.media-amazon.com/images/I/81mNf6vTyBL.jpg) ![Bioactive B12 - Image 3](https://m.media-amazon.com/images/I/81dkSib+oKL.jpg) ![Bioactive B12 - Image 4](https://m.media-amazon.com/images/I/71Ws-dNsDRL.jpg) ![Bioactive B12 - Image 5](https://m.media-amazon.com/images/I/81mnKV1ArOL.jpg) ## Questions & Answers **Q: I've read some of the 1 start reviews claiming it's just coloured water - is it?** A: 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. **Q: How is the product preserved if you don't add any preservatives?** A: 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. **Q: How quickly can I expect to see results from Bioactive B12?** A: 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. **Q: 3000mcg seems quite high compared to the recommended daily amount, why is this?** A: 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing for sleep problems! *by A***R on 7 July 2026* Amazing!!
