Main Highlights

Why nature provides’ bioactive B12? Bioactive B12 provides you with a high strength (3000mcg per daily dose) and highly bioavailable source of Vitamin B12. The liquid formula uniquely combines both Methylcobalamin and Adenosylcobalamin, which are already in a methylated, active form, making them readily usable by the body without the need for conversion ( helpful for those with the MTHFR gene mutation, which around 35% of the population have but are not aware).  
How to take bioactive B12? Easy to take and tasteless, Bioactive B12 is designed to be taken sublingually (under the tongue) for optimal absorption. Simply take 1ml (13 drops) and hold the liquid under your tongue for 30 seconds before swallowing. This method bypasses the gastrointestinal tract, allowing it to go directly into your bloodstream for faster and more effective results. The liquid formula makes it easy to adjust the dose to suit your daily requirements.
Support your health: Bioactive B12 promotes Mental Focus, a Healthy Nervous System, Cardiovascular Health (by fighting homocysteine), Energy Production, Adrenal Function and supports your Immune System. B12 is an essential vitamin which is involved in a significant number of actions within the body.
Premium quality, no additives: With just 3 ingredients (Methylcobalamin, Adenosylcobalamin and reverse osmosis water) Bioactive B12 is Vegan-friendly, 100% GMO-Free and contains NO colours, flavourings, sugar or preservatives. Packaged in Miron UV-proof glass for natural protection against UV light, we use only the purest ingredients.
Customer peace of mind: At Nature Provides, we aim to provide comprehensive information and support. If you have any questions, our friendly team is available to offer personalised assistance to help integrate this supplement into your lifestyle.
