Common Questions
What is the difference between the capsules and the powder?
Both contain the same freeze-dried beef spleen. The capsules (1.8 g per 3-capsule serve) are tasteless and convenient for travel. The powder (2 g per half-teaspoon serve) has a mild organ flavour and can be added to smoothies, broths, or cooked meals.
Does the powder need to be refrigerated?
The manufacturer does not state a refrigeration requirement. Store in a cool, dry place away from direct sunlight.
Is this product suitable for children?
The manufacturer does not specify a minimum age. Consult your healthcare professional before giving to children.
Is the beef spleen nutritionally different when freeze-dried versus fresh?
According to the manufacturer, freeze-drying removes water, concentrating the naturally occurring nutrients into a smaller volume, with the nutrient profile otherwise remaining virtually identical to fresh spleen.
Warnings & Storage
Store in a cool, dry place away from direct sunlight. Keep out of reach of children. If you are pregnant, breastfeeding, taking prescription medication, or have a medical condition, consult your healthcare professional before use. Stop use if you experience any discomfort.
