Sheep, goat, or deer placenta gets dried and turned into capsules or powders. Marketers push these for aging, energy, mood, or skin. No strong clinical evidence backs any of those uses. No standard dose exists, so amounts on labels jump all over the place. Any supposed active compounds would likely break down during digestion, making the claims guesswork at best.
Safety flags are real. Animal tissue can carry infectious stuff like prions or viruses. Regulators have raised alarms about this. The supplements might also contain hormones. People with hormone-sensitive conditions need extra care here. Pregnant or breastfeeding women should skip them entirely.
