The Ancestral Supplements Grass Fed Placenta Supplement is designed primarily for postpartum women, breastfeeding support, and those experiencing menopause symptoms. It contains two main ingredients: grass-fed beef placenta and liver, both known for their nutrient density. These capsules offer a natural source of highly bioavailable nutrients like heme iron, vitamins B6, B12, D3, and selenium, which can support skin elasticity, mood, and wellness during postpartum and menopause phases.

Scientific evidence specific to placenta supplements for menopause relief and stem cell support is limited, so results may vary between users. The taste is noted as 'placenta' flavor, which might be off-putting to some, though this is less of a concern in capsule form. With 180 capsules per container, the supply should last about a month. This supplement suits adult women seeking postpartum recovery or menopause symptom support through natural, whole-food-based nutrition. While it excels in high-quality ingredients and traditional usage, it may not meet expectations for strong clinical trial-backed stem cell benefits.
