Tag: Cysteine sources

Did you know that cysteine is a vital precursor to glutathione, often called the body's 'master antioxidant'? For those looking to increase their intake, identifying what food has high cysteine is a powerful way to support detoxification, immune function, and overall cellular health.

While the body can naturally produce some L-cysteine, dietary intake from various food sources is essential for maintaining adequate levels. This versatile semi-essential amino acid can be obtained from both animal and plant-based foods, as well as produced through industrial processes for supplements and additives.

Cysteine is a sulfur-containing, conditionally essential amino acid that is a crucial component of the potent antioxidant glutathione. It is primarily found in high-protein foods, playing a key role in detoxification, immune function, and tissue health.
