CitruIline

Citrulline is an amino acid that plays an important role in the human body. It is a precursor to arginine, which, in turn, is involved in the synthesis of nitric oxides, promoting vasodilation and improving blood circulation. On a keto diet, consuming citrulline can be particularly beneficial, as amino acids help preserve muscle mass and improve endurance during workouts. Additionally, citrulline aids in the removal …

Protein Metabolism

Amino acids and related compounds matter for muscle, liver, nervous system, immunity and tissue repair. Their role depends on total dietary protein, energy intake, training, liver function and kidney function.

Practical Meaning

On keto and LCHF, protein should not be reduced out of fear of gluconeogenesis. It is usually better to set enough protein and distribute it across meals than to compensate for a poor diet with isolated amino acids.

Sport And Recovery

For training, isolated amino acids matter less than total daily protein, meal distribution, sleep and overall energy. If the diet is low in protein, a supplement rarely solves the problem as well as real portions of meat, fish, eggs, cottage cheese or tolerated legumes.

When Caution Is Needed

With kidney or liver disease, pregnancy, cancer treatment, severe infections and inherited amino acid metabolism disorders, supplements should not be chosen by sport logic. Diagnosis, lab markers and the whole nutrition plan matter.
