8 B Vitamins make up the B complex family, and they all help your body convert food (carbohydrates) into fuel, otherwise known as glucose. The glucose produced is then used to produce energy.

In this post, we look at each B vitamin and its functions in the body.

We’ll also look at some symptoms associated with a B vitamin deficiency and some key dietary sources for each.

Below I have highlighted the important bits for you, just in case your schedule is tight.

Also supporting DNA production, the genetic material found in all cells, and helps prevent a type of anaemia called megaloblastic anaemia that makes people tired and weak.

A lack of vitamin B12 can cause memory loss, dementia, and numbness in the arms and legs.

Some people, particularly older adults, are deficient in vitamin B12 because they have trouble absorbing this particular vitamin from food.

B Complex Vitamins Essential Beauty Aids

Let’s not forget their significant contribution to natures beauty kit, keeping you young looking and full of vitality.

B Complex Vitamins are essential in the regeneration of cells, skin and the reduction of wrinkles.

It’s always best to cook fresh and get as many vitamins and minerals as you need from your diet.

However, there are many that you are unable to obtain from diet alone, or if you do, the quantities are not sufficient to requirements.

Supplements can help with this problem, but you must understand what they are and which ones are right for your individual need.

Too much can cause more harm than good; too little do no good at all.

My Thoughts

I currently take nine different supplements daily.

The more research I do, the more I realise just how unique our immune systems are.

It’s incredible how much your immune system does, and when at it’s healthiest, what it can potentially do.

Its primary role is to keep you alive and kicking, protecting you from and controlling infection, illness and chronic disease.

You should only take the vitamins supplements that individually suit you, your body and your immune system’s need. So a tailored approach is a must.

As always, all contributions to the discussion are encouraged and always very much appreciated.

      Hey Shia, 🙋🏽‍♀️

      Great to see you again, yes it can get confusing as to what foods contain what vitamins or minerals.

      Its save to say as long as you are eating a well balanced diet which includes meat, fish, dairy products, oils, plenty of fruit and veg you should be getting most of what your body requires.

      However, there some are vitamin and minerals is unable to produce on its own or has a hard time producing the levels needed dependent on gender, age or circumstance, this is when supplements are a good idea.

      Oh and not forgetting water make sure you keep hydrated at all times, just like a beautiful flower in the garden you need watering too.

      Thanks Shea 🙏🏽

      See You again Soon X:-).
