Amino acids are the building blocks of proteins, essential for the construction, repair and proper functioning of our body. Some of them are called "essential" because our body cannot produce them alone : they must be provided through diet or dietary supplements.
At BodyCheckup, we have formulated several supplements rich in amino acids to help you maintain your physical, cognitive, digestive or even skin balance.
Our dietary supplements formulated and enriched with amino acids
Amino acids intervene in functions as varied as hair growth, digestive comfort, sleep quality or sports performance. Our formulas integrate them in a targeted and natural way.
This complex combines L-Cystine and L-Cysteine, two sulfur amino acids essential for keratin synthesis, with horsetail extracts, nettle, MSM, zinc and B vitamins. A complete formula to promote growth, strengthen appendages, limit stress-related loss and stimulate the scalp.
Objective : Improve sleep quality and promote relaxation
Sleep plus is a supplement formulated with L-Tryptophan, an amino acid precursor of serotonin and melatonin, key hormones in mood and sleep-wake cycle regulation. Taken as a supplement, it promotes falling asleep, soothes tensions and helps regain emotional balance gently.
Objective : Optimize sports performance and limit fatigue
L-Leucine, L-Lysine, L-Valine, L-Phenylalanine, L-Threonine, L-Isoleucine, L-Histidine, L-Methionine, L-Tryptophan : a complete complex of 9 essential amino acids to support muscle energy, promote recovery and prevent soreness after exercise.
This pack combines L-Tryptophan with organic ashwagandha and magnesium for synergistic effect on falling asleep, relaxation and sleep quality, acting simultaneously on neurotransmitters and the nervous system.
Objective : Stimulate growth, strengthen fiber and limit loss
This duo combines the Hair & Nail Complex (rich in L-Cystine and L-Cysteine) with magnesium for complementary anti-stress action. It targets stress-related hair loss, strengthens appendages and improves overall scalp balance.
Objective : Improve cognitive functions and mental clarity
Formulated with L-Tyrosine, an amino acid precursor of dopamine and noradrenaline, this supplement supports cognitive functions, attention and motivation, especially during periods of stress, exams or mental overload.
Objective : Strengthen intestinal barrier and nourish enterocytes
Glutamine is a key amino acid for small intestine integrity. It nourishes enterocytes, strengthens immune barriers and promotes cellular regeneration of the digestive tract. This supplement is recommended in case of leaky gut syndrome, chronic inflammation or repeated digestive disorders.
What is the role of amino acids ?
Amino acids are the basic elements of proteins. Without them, our body can neither build nor repair its tissues, nor ensure certain essential functions. They participate in the manufacturing of enzymes, hormones, neurotransmitters and even immune cells.
Some amino acids are called "essential" because the body cannot produce them by itself : they must be provided through diet or targeted dietary supplements. Their action is multiple and concerns muscle as well as nervous, digestive, cognitive or skin well-being.
At BodyCheckup, we integrate these amino acids into specific formulas to meet concrete needs : improve sleep quality, strengthen hair and nails, support concentration, or accompany physical performance and recovery. Each complex has been designed to optimize their synergy, bioavailability and effectiveness.
