Onnit’s ACTIVE B Complete is an intelligent blend of B vitamins, which are used throughout our bodies for a plethora of essential bodily functions. B vitamins have been shown to play a vital role in nigh on everything our body does, including the conversion of nutrients into neurotransmitters, the generation of energy from food, keeping our nervous systems healthy, skin, eye and hair health, the creation of haemoglobin, the break down of fat and a host more too numerous to list here. If you want to live a happy and healthy life, then – B vitamins are fundamental. Onnit’s ACTIVE B Complete gives you the B vitamins that you need to survive and thrive, making it an excellent addition to a healthy diet and lifestyle.

The vast majority of vitamins are water-soluble, meaning that they don’t stay in the body for long periods of time and efficient absorption is absolutely key to making the most out of them. However, this is often trickier than it sounds and not everyone handles vitamin absorption as well as one would like. This makes Onnit’s decision to use methylated versions such as methylated B12 especially useful – as research shows that it is easier for our body to absorb it in this form. While Benfotiamine (a version of thiamine or B1) has shown more than 3 and a half times greater absorption in clinical trials. This all serves to ensure that Onnit’s ACTIVE B Complete Complex gives you a better chance to gain all the potential benefits that the B vitamins offer, when compared to comparable supplements.

B Vitamins are the fuel that help power your body’s most important systems – delivering cognitive and physical benefits when forming part of a healthy diet. They have the potential to give you the energy to perform better and enable you to maximise the potential of both your brain and your body. Just imagine all the benefits that things like enhanced focus have the potential to bring – enabling you to perform better at work or in the gym. B Vitamins are also associated with our circadian clock, enabling us to perform better when we are tired.

Onnit’s Total Complex B is effective as a standalone supplement, although, many people find improved results when they use it as a part of Onnit’s Total Human Complete Supplement Pack – an intelligently designed mix of nutrients that gives our body the things that it needs when it needs them. If you want to perform better in your daily life, then Onnit’s ACTIVE B Complete has the potential to give you that boost that you need.

Vitamin B1 (Thiamine) – Vitamin B1 or Thiamine is an essential water-soluble nutrient that is required by every single part of our bodies. Its main role is to help our bodies turn food into energy, via the production of adenosine triphosphate – the molecule that transports energy within our cells (Lonsdale, 2006). Onnit’s ACTIVE B Complete contains thiamine in the form of Benfotiamine a unique, lipid-soluble version of thiamine, which research suggests is more than three-and-a-half times more effective in raising the bioavailable thiamine levels, when compared to regular thiamine. This means that Onnit’s Total Human B Complex has the potential to enhance energy transfer and your metabolism – potentially boosting things such as concentration, athletic performance and much, much more. Complex B can be taken as a standalone supplement, although many people find improved results when they use it as a part of Onnit’s Total Human Complete Supplement Packs.

Vitamin B2 (riboflavin) – Vitamin B2 or Riboflavin is an essential water-soluble nutrient that is an important part of breaking down food, facilitating the absorption of other nutrients and maintaining our tissues (Powers, 2003). This means that it is vital to a whole range of bodily functions and a crucial part of any healthy diet.

Vitamin B6 – Vitamin B6 is a water-soluble vitamin that is associated with a host of different bodily functions, including more that 100 different enzyme reactions.

Vitamin B-12 – Vitamin B12 is a water-soluble nutrient that helps maintain our body’s blood and nerve cell health and is also associated with the production of DNA. It is also believed to help prevent a form of anaemia called megaloblastic anaemia that causes people to feel weak and tired (National Institues of Health and dietary supplements , 2018). However, the most common form of this important vitamin is known as cyanocobalamin, which is believed to be less effective. Onnit’s Complex B, uses Methylcobalamin, which is the only kind that can participate in homocysteine metabolism.

Folic Acid – Folic Acid is a kind of B Vitamin that is believed to help our bodies produce, maintain and repair cells, while studies also suggest that it may help police out things like free radicals that are associated with cancer (Reynolds, 2002). It is also associated with many benefits during pregnancy and is used as a treatment for some kinds of anaemia. Onnit’s ACTIVE B Complete contains the folic acid that your body needs to survive and thrive.

Biotin – Biotin is a water-soluble B Vitamin that is believed to help our bodies to convert nutrients into energy, alongside being fundamental to the maintenance of healthy skin, hair and nails (Said, 2012). This suggests that biotin is important both to our appearance and our health.

Vitamin B5 – Vitamin B5 or pantothenic acid is a water-soluble vitamin that is believed to be vital for all humans. Its functions include – helping to make red blood cells and aiding in the process of converting food to energy (Smith, 1996).
