Journal of the American College of Cardiology, 76(7), 844-857.

Vermeer, C. (2012). Vitamin K: the effect on health beyond coagulation - an overview. Food & Nutrition Research, 56, 5329. Cheese/curd K2 is from lactic-acid bacteria (mainly MK-8 and MK-9) and propionic-acid bacteria (mainly MK-10). MK-7 is almost exclusively Bacillus subtilis natto; MK-4 is from animal tissue (menadione conversion), not cheese lactic fermentation. 10.3402/fnr.v56i0.5329
National Institutes of Health, Office of Dietary Supplements. (2024). Vitamin B12 — Fact Sheet for Health Professionals. Fact sheet (updated July 2, 2025; Wayback snapshot 20 September 2026): multivitamin/mineral supplements typically contain 5 to 25 mcg B12, B-complex products 50 to 500 mcg, B12-only supplements typically 500 to 1,000 mcg; absorption is only about 2% at 500 mcg and 1.3% at 1,000 mcg; a 2018 Cochrane review of 3 RCTs (153 participants) compared very high oral doses (1,000-2,000 mcg) with intramuscular B12; high oral doses (e.g. 1,000 mcg/day) might be equally effective in Crohn's disease and appear as effective as hydroxocobalamin injections after Roux-en-Y bypass. These are product contents and trial doses; the sheet gives no recommended daily supplement range (fact sheet). ods.od.nih.gov/factsheets/VitaminB12-HealthProfessional

World Health Organization. (2015). Guideline: Sugars intake for adults and children. Geneva: WHO. Recommends reducing free sugars to <10% of total energy intake (strong recommendation), and suggests a further reduction to <5% (conditional). 'Free sugars' include monosaccharides and disaccharides added by the manufacturer, cook, or consumer, plus sugars naturally present in honey, syrups, fruit juices, and fruit juice concentrates — explicitly distinguishing them from the intrinsic sugars in whole fruit, vegetables, and milk. www.who.int/publications/i/item/9789241549028
