The Best Methionine: Our Picks
Guide: Questions you should ask yourself before buying methionine
What is methionine?
It is needed for the production and breakdown of substances such as, adrenaline, carnitine, choline, creatine, melatonin and nucleic acids. It also supplies the body with sulphur and methyl groups and is an important structural element for skin, hair and nails.
What is methionine used for?
Together with cysteine, methionine is one of the only sulphur-containing amino acids, which is why these two amino acids are essential for our metabolism.
Methionine can be used in combination with other active ingredients, such as S-adenosyl, to support depression treatment, dementia prophylaxis, alcohol-related liver disease and cirrhosis. (3)
How does methionine work?
The acidification comes from sulphate, which is excreted by the kidneys, whereby protons enter the urine, making it acidic.
Furthermore, methionine is said to improve the solubility of urinary stones and support treatment with antibiotics. In addition, a functional methionine cycle can lead to increased methilisation and protect the brain from damage. (4, 5)
How do I dose my methionine intake?
Dosages can usually be found in the package insert.
However, if you are taking methionine not as a food supplement but as a medicine, you should always consult a doctor about taking it, and also for food supplements if you are pregnant.
What side effects can methionine have?
If you are unusually tired, excitable or unresponsive after taking methionine, you should consult a doctor, as this may indicate acidosis of the blood.
What are the alternatives to methionine?
L-methionine can also be supplied to the body naturally, as some foods have a considerable amount of methionine. If you want to know more, there is a list of foods in the trivia section.
Decision: What types of methionine are there and which one is right for you?
Methionine preparations are divided into these two types:
In the following sections we go into detail about the advantages/disadvantages and areas of application of the two types of device.
Advantages and disadvantages of methionine capsules
Methionine capsules come commercially with a dosage of 500 mg per capsule. The capsules are pleasant to take by swallowing, and they dissolve in the stomach and take effect. The capsules make dosing very easy.
Advantages and disadvantages of methionine powder
Methionine powder is usually offered in larger quantities, often in kilo-packs. The powder is taken by mixing it with water. The amount of powder must be dosed by the user.
Buying criteria: You can use these factors to compare and evaluate methionine
The amount of capsules or powder varies between products from different manufacturers. The more you buy, the more you pay.
It is therefore worth checking how long you plan to take methionine supplements. If you are taking the supplements for a longer period of time, you can look for discounts and buy larger quantities. If the intake is only temporary, it is worth buying a smaller pack.
An important aspect when buying methionine preparations is the way in which they are taken. Essentially, a distinction is made between capsules and powder.
If you have problems swallowing capsules, you should of course opt for a powder. However, drinking such powder drinks can also be unpleasant. Therefore, it is worth being clear about your preferences before buying.
Many methionine preparations contain only methionine, while others contain other active ingredients.
If the product you are interested in contains other active ingredients in addition to methionine, you should find out about them first, as you may be killing several birds with one stone or solving one problem but creating another.
Some supplements contain other active ingredients in addition to methionine.
Some supplements are plant-based and/or labelled organic, these supplements contain L-methionine, the naturally occurring form of methionine.
If it is important to you to use organic or plant-based products in your diet, you can safely consume them. The products are always clearly labelled.
When buying medicines or dietary supplements with methionine, it is also worthwhile to refer to testimonials from people who have already taken these preparations in order to better assess their effect.
Good sites to look at testimonials are product sites with user ratings like medpex.de or sanego.de. Internet forums are also a good place to find testimonials.
Facts worth knowing about methionine
What foods contain methionine?
There are several foods that contain methionine. Usually the content of methionine and cysteine is given together, as methionine is a precursor of cysteine. Here is a list of foods with a high methionine/cysteine content:
|Food (100g)||Methionine/Cysteine Content|
|Cashew Nuts||380 mg|
|Wheat Germ||280 mg|
How long should I take methionine?
Unfortunately, there is no blueprint that we can give you here; the duration of intake depends on your complaint and your personal disposition.
Therefore, you should always consult a doctor or health professional and get competent personal advice.
Is methionine also important for animals?
Yes, methionine is also an essential metabolic product for animals and should be supplied to the animal in sufficient quantities.
This can be achieved through the feed or through special dietary supplements. If you want to supply your animal with enough methionine, sesame, soy, chia or linseed are good methionine suppliers.
