In all the five studies, an oral (Delpres study via sublingual route) dose of 1000 g vitamin B 12 was used with the exception of Kuzminskis study, whereby a higher dose of 2000 g was used
Growth Hormone-Releasing Hormone and Growth Hormone Secretagogues in Normal Aging
This decline is associated with disruptions to circadian rhythm, immune function, and cellular repair

Dietary sources of vitamin B12 include: Meat and poultry: Beef, lamb, pork, and chicken are excellent sources Fish and seafood: Particularly salmon, trout, tuna, and shellfish Dairy products: Milk, cheese, and yoghurt provide readily absorbed B12 Eggs: Especially the yolk Fortified foods: Many breakfast cereals, plant-based milk alternatives, and nutritional yeast are fortified with B12 For vegans and vegetarians , who are at increased risk of deficiency, the Vegan Society and British Dietetic Association recommend: Regular consumption of fortified foods (at least three servings daily) Consideration of B12 supplements (typically 10 micrograms daily or 2000 micrograms weekly) Monitoring of B12 status as advised by a healthcare professional based on individual risk Supporting overall hair health involves a holistic approach: Maintaining a balanced diet rich in protein, iron, zinc, and biotin Ensuring adequate hydration Managing stress, which can affect hair growth cycles Avoiding harsh chemical treatments and excessive heat styling Protecting hair from environmental damage When to seek medical advice: If you follow a vegan diet and have not arranged B12 supplementation If you have conditions affecting nutrient absorption (coeliac disease, Crohn's disease, previous gastric surgery) If you take medications that may interfere with B12 absorption long-term If you experience symptoms suggestive of deficiency It is important to recognise that whilst optimising B12 status supports overall health, supplementation will not reverse age-related greying in most cases
