Understanding Chia Seeds Nutrition

Chia Seeds are a nutrient-dense nut or seed rich in healthy fats, fiber and minerals. At 493 kcal per 100 g serving, they provide 16.8g of protein, 43g of carbohydrate and 31.1g of fat. Chia Seeds are particularly rich in magnesium, delivering 339mg — 82% of the daily value — in a single serving. They're a good source of fiber and low in sugar.

For athletes and anyone tracking macros, chia seeds are calorie-dense despite their small typical serving, so they're easiest to track in small, pre-measured portions rather than free-pouring. Their fiber and micronutrient content still make them a useful addition to a balanced macro split, but the calories add up quickly for such a small volume.
