Energy and Fatigue

Feeling tired can have many causes: not enough sleep, prolonged stress, a diet low in certain nutrients, intense training or health changes that deserve to be checked. In the Energy and Fatigue collection we bring together food supplements from brands such as Thorne, NOW Foods, Biocare, Solaray, Designs for Health and Zeinpharma, in capsule, tablet, powder or liquid form, with several vegan options.

Vitamins and minerals for tiredness and fatigue

Before looking for more specific formulas, it is worth making sure you are not missing any essential nutrient. Vitamins B2, B3, B5, B6 and B12, folate, vitamin C, iron and magnesium contribute to the reduction of tiredness and fatigue. Vitamin B1, biotin and iodine contribute to normal energy-yielding metabolism.

Iron

Iron contributes to normal formation of red blood cells and haemoglobin and to normal oxygen transport in the body. You will find iron as bisglycinate, citrate and fumarate, in capsules or liquid. If you suspect a lack of iron, talk to your doctor about a ferritin test before supplementing.

B complex and vitamin B12

We offer B complex and vitamin B12 formulas with active forms such as methylcobalamin, methylfolate and P-5-P. People who follow a vegetarian or vegan diet get little vitamin B12 from food.

Magnesium

Magnesium is available in several forms: bisglycinate, citrate, malate, taurate and L-threonate. As well as contributing to the reduction of tiredness and fatigue, it contributes to normal muscle function and normal functioning of the nervous system.

Multivitamins

For those who prefer a complete daily option, multivitamins and multinutrients combine vitamins and minerals in a single serving.

Other ingredients in the collection

The collection also includes coenzyme Q10 and ubiquinol, D-ribose, NADH, acetyl-L-carnitine and L-carnitine, SAMe and plants such as rhodiola, ashwagandha, ginseng, maca and cordyceps. Check each product page for the full composition.

How to choose the right supplement

Use the filters to choose by ingredient, brand, format or availability. If tiredness lasts for several weeks or appears for no apparent reason, consult your doctor or pharmacist.

Perguntas frequentes

What supplements can help fight fatigue?
Magnesium, iron, vitamin C and B-complex vitamins (B6, B12, folic acid) help reduce tiredness and fatigue. The choice depends on the cause and your needs.
How long do they take to take effect?
It depends on the nutrient and the person. Some effects, like those of caffeine, are felt in minutes; correcting deficiencies, such as iron deficiency, can take several weeks of regular intake.
Can diet replace these supplements?
A balanced diet is the foundation of energy. Supplements help when there is a greater need or deficiencies, but they do not replace healthy habits of eating, sleeping, and exercising.

Food supplements are not a substitute for a varied and balanced diet or a healthy lifestyle. If you are pregnant or breastfeeding, consult your doctor before taking this supplement. Not recommended in case of hypersensitivity or allergy to any of the ingredients in the formulation, or when interactions between another product and any of its constituents are described. The recommended daily dose should not be exceeded. Keep out of the reach and sight of children. Store in a cool, dry place, away from light.
