    B-complete Oral Spray contains the most bioavailable ingredients to ensure optimal absorption and metabolism by the body. Including both forms of B12, adenosylcobalamin and methylcobalamin, to support the body’s natural energy pathways.

    Importance of B-complex vitamins

    • Biotin (B7) contributes to the maintenance of normal hair and skin
    • B6 and Folate (B9) contribute to the normal function of the immune system
    • B3 and B5 contribute to normal functioning of the nervous system and psychological function
    • Riboflavin (B2) helps to protect cells from oxidative stress and maintain healthy red blood cells
    • B5 and B12 contribute to normal energy metabolism to aid the reduction of tiredness and fatigue

    Active Methylfolate

    Traditional B-complex supplements may contain a synthetic form of folic acid as their source of folate, which is not biologically active and needs to be converted via a multi-step process before it can be metabolised by the body. B-Complete Oral Spray uses a form of methylfolate in its most active form so it can be easily utilised by the body.

  • FAQs
      Is the this spray suitable for children?

      This spray is perfectly suitable for children and is ideal for those who may not want to or cannot take capsules. For children under 12 years of age, we recommend halving the dosage, as their daily supplementation need is lower than that of an adult.

      Do I need to take the spray with food or drink?

      No. The oral spray delivery mechanism avoids primary processing by the digestive system, meaning it can be taken at any time of day with or without food. The active ingredients are delivered directly into the bloodstream via the mucosal membranes in the mouth.

      What time of day should I use the spray?

      The spray can be taken at any time of day, the key is to make it part of your daily routine.

      Many people find it is easiest to take it first thing in the morning as part of their morning routine, but as the sprays are easy to use, portable and don’t need to be taken with food or drink, they can be used any time of day.
