Vitamin Bp

Vitamin Bp, also known as choline, is not one of the traditionally recognized B vitamins, but it has sometimes been classified under the B vitamin group due to its similar functions. However, the term "Vitamin Bp" can also refer to other compounds that were once considered part of the B vitamin complex but are no longer recognized as such. For instance, "Vitamin Bp" might be associated with inositol or other substances that were initially thought to be B vitamins but are now understood to have different roles[1].

In terms of food and beverages, inositol, which might be referred to as "Vitamin Bp" in some contexts, is not typically added as a supplement in the same way other B vitamins are. However, inositol is naturally present in various foods such as nuts, seeds, beans, and whole grains. It can also be found in some fortified foods and dietary supplements, although its primary use is not as a vitamin but rather for its potential benefits in mental health, fertility, and other health conditions. In the food industry, inositol is more commonly used for its functional properties rather than as a vitamin supplement[1].

Vitamin B12, also known as cobalamin, is primarily produced through the fermentation of selected microorganisms. The most commonly used bacteria for this purpose are Pseudomonas denitrificans (now reclassified as Ensifer adhaerens) and Propionibacterium freudenreichii subsp. shermanii. These bacteria are grown in large vats, typically over 100,000 liters, for a period of 7-10 days. The fermentation process allows these microorganisms to naturally produce vitamin B12, which is then recovered from the culture medium through a series of steps including precipitation, chromatography, and crystallization[1][2][3].

Recent advancements have led to the development of a more environmentally friendly and sustainable production method. Professor Martin Warren and his team have engineered a recombinant Escherichia coli strain that is capable of producing high levels of vitamin B12. This new strain improves the cobalt uptake and delivery systems, resulting in nearly 100% incorporation of cobalt into the vitamin, thereby eliminating the creation of hazardous waste and making the manufacturing process more affordable and sustainable[2][3].

Safety Profile for Human Consumption of Vitamin B6

Vitamin B6, when consumed through supplements, has a notable safety concern related to the risk of peripheral neuropathy. This condition can manifest as tingling, burning, or numbness in the hands and feet. Even low doses of vitamin B6, less than 50 mg per day, can lead to this side effect, although the risk increases with higher doses and the use of multiple products containing vitamin B6. Regulatory bodies, such as the TGA, have implemented new labelling and use regulations to warn consumers about this potential side effect, including reducing the maximum permitted daily dose to 100 mg for adults and requiring warnings on products containing more than 10 mg of vitamin B6 per day[1].

Potential Contamination Risks

While the primary concerns with vitamin B6 supplements are related to their direct health effects, there are also potential risks associated with contamination. These risks are more general to dietary supplements rather than specific to vitamin B6. Supplements can be contaminated with heavy metals, which can occur during the sourcing of raw materials or through manufacturing processes. Additionally, there is a risk of pathogen contamination, such as bacterial contamination, as seen in cases where products were recalled due to potential contamination with bacteria like Burkholderia cepacia, which can pose serious health risks, especially to vulnerable populations like infants and those with weakened immune systems[2]. Pesticide exposure is another concern, although it is more relevant to the cultivation of food sources rather than the production of vitamin supplements themselves. However, ensuring that all ingredients are sourced from safe and regulated environments is crucial to minimizing these risks[3].
