Vitamin B12 - Everything you need to know
In the following, we will tell you everything you need to know about vitamin B12. Among other things, we clarify what benefits vitamin B12 can have for you or how much you should generally take. Did you know that vitamin B12 is important for the formation of red blood cells?
What is vitamin B12?
Like vitamin C, vitamin B12 belongs to the group of water-soluble vitamins. Moreover, vitamin B12, also known as cobalamin, is the only vitamin that the body can store for several years, especially in the liver. However, a so-called intrinsic factor is required for the absorption of vitamin B12. Simply put, this is a special protein that is formed in the stomach lining of humans.
What foods contain vitamin B12?
Everyone can absorb vitamin B12 through their diet. Meat, fish, seafood, dairy products and eggs are considered rich in vitamin B12. As you can see, especially foods of animal origin have a high vitamin B12 content. In a normal balanced diet, the vitamin B12 content is actually covered. However, the supply of vitamin B12 is problematic, especially for vegans, which is why the DGE (German Nutrition Society) recommends regular supplementation of vitamin B12 for vegans.
Our One Bear A DAY Vitamins and our Trust Your GUT Vitamins also contain vitamin B12.
What are the benefits of taking vitamin B12?
Many people do not know how important vitamin B12 actually is because the focus is often on other vitamins. Vitamin B12 is very important for cell division and differentiation, for the formation of red blood cells, for protein metabolism and for the development of nerve cells, especially in the spinal cord. Reportedly, a high injected concentration of vitamin B12 helps boost metabolism. However, there is no scientific evidence to support this.
NASSIM JAMALZADEH:
"It's really important to take care of your vitamin B12 budget because vitamin B12 is involved in cell division and differentiation or blood formation. That's why regular intake of vitamin B12 is essential."
ALL QUESTIONS ABOUT VITAMIN B12
ALL QUESTIONS ABOUT VITAMIN B12
How often should I take vitamin B12?
The frequency of intake of vitamin B12 depends on each person. If you consume plenty of it through your diet and can thus cover your daily needs, an additional intake is not necessary. It's best to ask your doctor and have regular blood work done. Additional supplementation of vitamin B12 is especially recommended for vegetarians and vegans.
How much vitamin B12 should one take?
This depends mainly on gender and age, as well as various other factors, such as whether you are pregnant, breastfeeding or have any diseases. The NHS (National Health Service), however, recommends a daily amount of about 4µg. However, it must be mentioned that the information from the NHS are recommendations and not maximum amounts.
Can you take too much vitamin B12?
Overdosage of vitamin B12 is very rare since the body normally either excretes excess vitamin B12 in the urine or absorbs it through the intestinal wall. Accordingly, there are hardly any known side effects of overdosage. However, an overdose of vitamin B12 is possible in people who suffer from leukaemia, liver metastases or liver inflammation, as in hepatitis.

At my age (I’m 67), maintaining good heart health is a top priority. I’ve been taking Make My Heart Beet for about a month now, and I must say, I feel more supported in my daily well-being. It’s comforting to know I’m doing something small yet meaningful every day for my heart. I’ll continue with this routine, and I’m glad to have found a vegan supplement that fits seamlessly into my life.

My experience
The Snack Smart bears really help curb my afternoon cravings – I feel more in control without needing extra snacks. And the Ah-mazing Hair gummies? My hair feels stronger, shinier, and just healthier overall.

My hair's new daily treat

Great taste – and it really helps with cravings!
I’ve been taking the Snack Smart Appetite Control gummies for a few weeks now and I’m honestly impressed! The apple flavour is super tasty, and I love that they’re vegan free.
I take 2 bears a day, as suggested, and I’ve noticed that my cravings between meals have definitely decreased. I feel more in control, especially in the afternoon when I used to snack the most.

Great tasting vitamins. Noticed a slight growth in my hair despite not having taken it for too long!

The bloat is gone!
I've been using these for just over a month now and will rave about them to anyone! I usually suffer with awful bloating and cramps and after 2 weeks of using these little bears that has practically gone! I finally like how I look and feel again and don't have to worry about going out for food with friends! They are also really tasty!

Amazing results
I’ve been using these gummies for a few weeks now, and I am absolutely thrilled with the results! From the very first few days, I noticed a significant boost in my energy levels without the jitters or crashes I usually get from other metabolism-boosting supplements

Perfect!
After 2 weeks I started to feel positive changes. They are tasty and I am enjoying them.

I have a very fair complexion and have observed a slight improvement in my skin tone since using these products. While the change is not substantial, it is sufficient for me to feel pleased and self-assured without the need for artificial tanning. Additionally, they have a pleasant taste.
