TY - JOUR T1 - Experimental Analysis of Pantohematogen as A Functional Component in Dietary Supplements: Safety Evaluation AU - Daniel Fischer AU - Thomas Braun AU - Laura Meier AU - Stefan Koch JF - EAMD 3 Y1 - 0 VL - 0 IS - 0 SP - 124 N2 - This study was conducted to evaluate the safety profile of Pantohematogen, a substance derived from the velvet antlers of the Altai Wapiti, which is commonly used as a functional ingredient in dietary supplements. In this clinical research, both male and female Wistar rats received the maximum tolerable intragastric dose of Pantohematogen. Over the course of six months, researchers monitored the animals for changes in general health status, body mass, hematologic and bone marrow parameters, and the functioning of major organs, including the liver, kidneys, heart, and brain.Throughout the experimental period, the animals exhibited stable behavior and maintained normal fur condition, appetite, reflex responses, and gastrointestinal and urinary tract function. No signs of a toxic response were detected following intragastric administration. However, administration of Pantohematogen at 250 and 500 mg/kg resulted in increased liver mass and reduced testicular size in male rats. This condition persisted for 2 weeks after treatment cessation. Other internal organs showed no abnormalities when compared with control and untreated animals.Importantly, the tested doses exceeded standard human-equivalent levels (per kilogram of body weight) by factors of 2, 10, and 20, respectively. Despite this, the findings indicated no evident toxicological impact from Pantohematogen exposure. This research was conducted at the Tomsk National Research Medical Center of the Russian Academy of Sciences under the supervision of Dr. N.I. Suslov, Doctor of Medical Science.
