Vitamin D Deficiency Manifests as Increased Appetite and Reduced Immunity, Endocrinologist Warns
Low levels of vitamin D in the human body can manifest through a weakened immune system and a distinct tendency toward overeating, according to endocrinologist and nutritionist Anton Polyakov.
Polyakov stated in an interview with the newspaper aif.ru that insufficient vitamin D typically shows up as depressed mood and disrupted eating behavior, which includes an intense craving for food alongside a propensity to overeat. The physician also connected the deficiency to reduced bone strength and the development of anxiety-depressive states. Previous research conducted by British scientists indicated that regular physical activity helps maintain vitamin D levels in the body even without taking special supplements.
Hidden Symptoms and Dietary Challenges Identified by Medical Specialists
Additional medical commentary expands on the subtle indicators of insufficient vitamin D. Polyakov reiterated to the publication that lowered mood and heightened food cravings serve as primary markers of the deficit.
Addressing the difficulty of obtaining sufficient nutrients through diet alone, endocrinologist and nutritionist Alexei Kalinchev explained to Radio 1—as covered by Spbdnevnik.ru and VSE42.Ru—that even fortified foods contain only minimal amounts of the vitamin. Kalinchev noted that individuals with naturally adequate levels without supplementation are rare, as the nutrient is difficult to absorb in sufficient quantities from food sources alone.
Supplement Safety and Daily Dosage Recommendations
Kalinchev connects vitamin D directly to the body’s antiviral and antitumor immune defenses, recommending year-round intake determined by individual blood tests. He cited a standard daily dosage range of 5,000 to 10,000 international units (IU), though he emphasized that precise amounts require professional medical oversight based on diagnostic results.
When purchasing supplements, Kalinchev advises consumers to select licensed pharmaceutical medications rather than general dietary supplements or nutraceuticals. He warned that non-pharmaceutical products frequently lack stringent regulatory oversight regarding label accuracy, leaving buyers vulnerable to ineffective products.
Frequently Asked Questions About Vitamin D Deficiencies
How can physical activity influence vitamin D levels?
Researchers from the United Kingdom concluded that regular physical exercise assists the body in maintaining stable vitamin D levels without the mandatory use of dietary supplements, according to findings cited by Lenta News and Infox.ru.
Why is it difficult to get enough vitamin D from food?
Endocrinologist Alexei Kalinchev explained on Radio 1 that very few people maintain adequate vitamin D levels through diet alone because the nutrient is difficult to absorb efficiently from food, and even specially fortified products contain only minor additive amounts.
What distinguishes pharmaceutical vitamin D from regular supplements?
According to Alexei Kalinchev, pharmaceutical medications undergo strict regulatory control to ensure their contents match the label, whereas general nutraceuticals often lack consistent quality checks and verification.
