Best Amino Acids (General)-Rich Foods for Guinea Pigs

Ranked by amino acids (general) content among foods safe for guinea pigs in the Creature Feast catalog.

Timothy Hay per 100g dry: ~7-11g protein providing a broad spectrum of amino acids Timothy hay is the primary protein and amino acid source for guinea pigs, providing approximately 7-11% crude protein. While its amino acid profile has lower concentrations of lysine and methionine compared to legume hays, the sheer volume consumed daily means hay provides the bulk of all amino acids. Quality pellets are formulated to complement hay's amino acid profile.

Peas per 100g: ~5.4g protein with strong lysine (0.32g) and leucine (0.32g) Peas have one of the most complete amino acid profiles among guinea pig-safe vegetables. They are particularly strong in lysine and contain meaningful amounts of all essential amino acids. A few peas as an occasional treat boost overall amino acid quality, especially complementing timothy hay's weaker areas.

Kale per 100g raw: ~4.3g protein with a broad amino acid spectrum Kale provides moderate protein with a reasonably balanced amino acid profile for a leafy green. It contributes to the overall amino acid mix when included in the vegetable rotation several times per week. Dark greens like kale generally have better amino acid diversity than pale lettuces.

Broccoli per 100g raw: ~2.8g protein with well-distributed essential amino acids Broccoli offers moderate protein with a good amino acid spread, including meaningful amounts of leucine, lysine, and isoleucine. A small floret several times per week adds valuable protein variety to the diet. Broccoli's amino acids complement those in hay and other greens well.
