Does collagen always have to come from animals? Although plants don't produce it, there's another way to provide the body with the substances needed for its own production.

Ligaments, tendons, and cartilage are not indestructible. If we constantly overwork our bodies and don't give them space to regenerate, connective tissues gradually lose their reserves. Training is a stimulus, regeneration is adaptation, and nutrition provides the material.

Muscles often adapt more quickly during training than tendons, ligaments, and cartilage, which need more time to adapt.
Therefore, for long-term healthy movement, it makes sense to address not only strength but also technique, regeneration, and nutrition of connective tissues.
