Combine Seeds: In a large glass jar or bowl, add 2 tablespoons chia seeds, 1 tablespoon ground flaxseed, 1 tablespoon sunflower seeds, and if using, 1 teaspoon pumpkin seeds and ½ teaspoon fennel seeds.
Add Liquid: Pour in 1½ cups of filtered water or unsweetened coconut water. Stir well to prevent clumping, especially with chia seeds.
Soak Overnight: Cover the jar or bowl and refrigerate for at least 6–8 hours, preferably overnight. This allows the seeds to swell, soften, and release their soluble fiber.
Add Lemon Juice: In the morning, stir in the juice from ½ a fresh lemon. This adds flavor and boosts digestion.
Drink or Strain: Drink the mixture as-is, including the gelled seeds for maximum fiber, or strain it if you prefer a smoother tonic.
Optional: For extra taste or detox support, add a few mint leaves or a splash of apple cider vinegar and cranberry juice.
