Buying vitamins and other supplements is way too complex with so many options so on this page I want to provide some good examples of products that seem to be high quality and have particular advantages like easy absorption.
There's no way I can guess which of the options I include will be OK with your digestion so if you try something and find it problematic in some way try to work round it – try it with food or on an empty stomach. You might find that for example magnesium glycinate is better for you than magnesium citrate.
Similar with other supplements trying a different version may suit you down to the ground. About now is the right time to mention that some of the vitamins are used up in the body very quickly and any amount not used up is lost from the body in the urine. These vitamins must be topped up frequently – like vitamins B and C.
Other vitamins can be stored in the body and do not need to be taken every day like vitamins D and E. Let's start with vitamin A and go through the vitamin alphabet Vitamins help us remain healthy and vitamin A helps to nourish the eyes and protect them from inflammation by toxic smog and environmental pollution.
Vitamin A can be found in vegetables like sweet potato, carrots and greens and also in eggs, cheese and salmon. The vitamin A found in vegetables are called carotenoids and the type of vitamin A found in non vegetarian foods like fish and shrimp and eggs is called the retinoids Vitamin A then has a vegetable form, the carotenoids and an animal form, the retinoids. And in the body carotenoids are converted into retinoids as and when the body requires them.
So your vitamin A tablets will be either carotenoids like beta carotene or retinoids the oil based vitamin from fish. There is a possible problem with this "oil soluble" version of vitamin A – if you eat too much it can build up in the body with a possibility of harm if you overdose a lot.
Beta carotene – the vegetable form of vitamin A does not have this problem and you can eat vegetables and take carotenoids with no problems at all because the body will convert carotenoids into retinoids when it needs them and not cause any harm.
