⭐ ESSENTIAL: Amino acids are essential for the synthesis of proteins including hormones and enzymes. Even though they are taken up through food, an additional supplementation may be necessary.

🌱 NATURAL – NOT SYNTHETIC: The amino acids in our EAA tablets are obtained through natural fermentation and are not produced synthetically. Some manufacturers offer amino acid tablets made from wheat or soy protein, which could cause problems for people with allergies. The amino acids in our tablets are available in free form and can be directly utilized by the body.
🔎 WITHOUT ADDITIVES: Our EAA tablets contain 1000 mg of all essential amino acids (leucine, valine, isoleucine, lysine, methionine, threonine, phenylalanine, tryptophan) including BCAA and the semi-essential amino acid Histidine. We do not use any additives such as magnesium stearate, microcrystalline cellulose or artificial flavours and sweeteners, which are usually found in EAA powder. Suitable for vegans. 300 tablets per bottle. Recommended daily dosage: Up to 6 tablets. Lab tested.
🌿 VEGAVERO CLASSIC: Our Classic line is defined by high-quality vegan supplements that cover a wide range of essential nutrients, plant extracts, vital mushrooms, and other functional ingredients. We focus primarily on individual ingredients and always avoid artificial additives like unnecessary fillers. Our Classic products are constantly tested and improved by our team based on the most recent scientific findings. Vegavero Classic – for us this means quality, safety, and practicality.
💓 BY YOUR SIDE: Caring for you is part of our philosophy. So, in addition to providing supplements designed for your needs, we work on unique formulas to achieve the perfect synergy of ingredients and dosages for you. If you have any queries, we are happy to advise and support you in your goals, and/or provide you with the certifications of each product and to answer all your questions.
