Best supplements for swimmers

Supplements for swimming: although it may be understood that supplements are intended for non-marine sports, good nutrition and supplementation is also key for those sports that take place in the water, due to the demanding requirements that swimmers have when practising this sport.

Do you know which are the most demanded supplements by swimmers? Take a look at the following post we have prepared.

What should a swimmer eat?

As for all people who do sport, the basis of sporting performance is based on correct nutrition, good rest and careful training. For a sport like swimming, where a large number of the body’s muscles are involved, the right diet and nutrition are key.

Do you know what you should eat if you are a swimmer? Some of the nutrients that should not be missing in your daily diet are:

  • Carbohydrates: which you can add through pulses, cereals or potatoes. Add energy for your workouts.
  • Proteins: to help in the recovery and construction of muscle fibres. Eggs, dairy products or chicken are the best food sources.
  • Healthy fats: which you can ingest through oily fish or also through certain fruits and nuts.

It is important to get into the habit of drinking, even if you don’t feel thirsty. It is a common misconception that being in the pool does not dehydrate you. Hydrate before, during and after training with water and sports drinks to compensate for water, glycogen and mineral losses.

In addition to natural sources, food supplements will become your daily ally, in order to complete your daily nutrition: vitamins, minerals, proteins, amino acids, carbohydrates…

Nutritional requirements of a swimmer

An important aspect, if training is fundamental for improving sporting performance, so is a good diet, which will allow you to give the best of yourself and progress in the pool or the sea.

Recovery Suplements

The right nutrition can contribute to more than 60% of the personal progress you can achieve through daily training.

What are the nutrient requirements of a swimmer?

If we are talking about an amateur swimmer, a daily intake of no more than 55 kcal per kilogram per day will be necessary, distributed as follows:

  • Carbohydrates: 3 to 6 g per kg per day.
  • Protein: 1.5 to 1.7 g per kg per day.
  • Fats: 1 to 2 g per kg per day.
Please note: these recommendations will vary depending on the training load and duration of the session. We have taken as a reference those given for an amateur swimmer, not a professional one.

Swimming supplements

Supplements will complement the daily nutrition of swimmers, covering possible deficiencies that the natural diet cannot reach, as well as supporting muscle recovery after training and competitions in the sea or pool.

Are you sure what to take and where to buy the best sports supplements for swimming? Here’s a quick guide to help you complete your diet to help you achieve your best sporting results.


These are key nutrients to get the energy you need before a full workout in the water, as well as to complete the start of optimal post-exercise recovery.

However, the easiest options to take are found in swimming supplement formulas such as those developed by our HSN R&D team, which are easy to assimilate and palatable.

As the supplement with the most studies on its contribution to sports performance behind it, creatine is also an important supplement for swimmers.

It is a substance that strengthens and improves the movements of high intensity and short duration, such as a large number of distances and swimming specialities.

At HSN you have options in different formats, with which to add creatine to your supplementation routine if you practise swimming, we have specialised and trusted brands that contribute to offering the best solution. Among them is our Raw Series line, a brand made with the highest quality raw materials on the international market.


This is a non-essential amino acid synthesised by the liver, which, together with histidine, forms the dipeptide carnosine. With the correct supplementation of beta-alanine, we can increase carnosine at a muscular level with its beneficial consequences for all those who practice swimming. Its ergogenic effect concentrates on reducing fatigue thanks to the improvement of the capping capacity at an intramuscular level.

In our online shop you can buy natural supplements that will give you an extra boost to achieve your goals, and that you should accompany with a healthy, rich and varied diet, as well as a healthy lifestyle with daily sport.

Among the best-rated supplements, you will find Beta-Alanine Powder from Raw Series, with no additives and suitable for vegans and vegetarians.

Vitamins and minerals

Supplement your nutritional requirements with the most important vitamins and minerals, which are key to normal body functions, even more important when it comes to sport.

Vitamins such as C and E are recognised by the EFSA as helping to reduce muscle damage after sport. In addition, swimmers are often deficient in vitamin D, the sunshine vitamin, especially at times of the year when we spend fewer hours exposed to sunlight.

At HSN you will find vitamins in different formats, as well as multivitamin formulas that will offer you the main vitamins and minerals to provide your body with on a daily basis.

When should a swimmer take supplements?

You can either take an Evoenergy gel (with the option of gels with caffeine and guarana available) or Evocarbs 2.0 in drink format with water. Both options will give you the energy you need for the session thanks to the carbohydrate loading provided.


You can take a break during your sessions to hydrate. A good option is the Evotonic, formula, a key isotonic for electrolyte replenishment during sport. You can also continue taking Evocarbs 2.0 as a second option.


It’s time to get the optimal nutrients for a better and faster recovery, key to be in optimal muscle condition for the next workout.

Among the options, the most complete is Evorecovery, although you can also opt for an Evogummy and a whey protein shake (Evowhey Protein 2.0 or Evolate 2.0). The aim is to ingest carbohydrates and protein to restore muscle glycogen and support the rebuilding of muscle fibres.
