摘要
Vitamin K2在钙调节中发挥关键作用——防止钙在冠状动脉和关节等软组织中积聚，同时将其引导至骨骼以增强结构强度。这与Vitamin K1不同，后者主要支持血液凝固。Dr. Berg概述了K2的顶级食物来源及推荐剂量方案，包括将K2与Vitamin D3搭配使用。
核心要点
- K2 ≠ K1：K1主要用于止血；K2负责管理体内钙的分配
- K2的主要功能：防止钙在软组织（冠状动脉、关节）中积聚，并将其引导至骨骼
- 维持剂量：每天100微克K2
- 治疗剂量：每天最高400微克
- 始终将K2与D3搭配使用：遵循1:100的比例（每10,000 IU的D3搭配100 mcg K2）
- 纳豆是K2含量最高的食物来源，其次是动物内脏和陈年奶酪
- 食物品质至关重要：选择牧场散养、有机及草饲来源，以最大化K2含量
详细内容
K2与K1的区别
这是两种功能各异的独立维生素：
- K1 — 参与血液凝固；缺乏可能导致瘀伤
- K2 — 调节钙代谢，保护cardiovascular health并支持bone density
剂量方案
| 目标 | K2剂量 | D3剂量 |
|---|---|---|
| 维持 | 100 mcg | 10,000 IU |
| 治疗 | 200 mcg | 20,000 IU |
| 最大治疗量 | 400 mcg | 40,000 IU |
Dr. Berg强调将K2与D3搭配使用，因为两者在calcium metabolism中具有协同作用。
维生素K2的顶级食物来源（由高至低）
- 纳豆 — 发酵大豆制品；K2含量最丰富的单一来源
- 动物内脏 — 鹅肝、鸭肝、鸡肝、牛肝（推荐以肝酱形式食用）
- 蛋黄 — 优先选择牧场散养、有机鸡蛋
- 草饲牛肉
- 鸸鹋油
- 硬质和软质奶酪 — 特别推荐Gouda奶酪
- 发酵／腌制肉类 — 意大利辣香肠、萨拉米香肠、猪肉香肠
- 草饲乳制品 — 黄油、酸奶油、奶油奶酪
- 酸菜 — 含有少量K2
品质注意事项
对于鸡蛋、牛肉和乳制品，牧场散养、有机及草饲选项的K2含量明显高于传统养殖产品。

Summary
Vitamin K2 plays a critical role in calcium regulation — preventing calcium buildup in soft tissues like coronary arteries and joints, while directing it into the bones for structural strength. This is distinct from Vitamin K1, which primarily supports blood clotting. Dr. Berg outlines the top food sources of K2 and recommended dosage protocols, including pairing K2 with Vitamin D3.
Key Takeaways
- K2 ≠ K1: K1 is primarily for stopping bleeding; K2 manages calcium distribution in the body
- K2’s main function: Prevents calcium from accumulating in soft tissues (coronary arteries, joints) and directs it into bones
- Maintenance dose: 100 micrograms of K2 per day
- Therapeutic dose: Up to 400 micrograms per day
- Always pair K2 with D3: Follow the 1:100 ratio (100 mcg K2 per 10,000 IU of D3)
- Natto is the highest food source of K2, followed by organ meats and aged cheeses
- Food quality matters: Opt for pasture-raised, organic, and grass-fed sources to maximize K2 content
Details
K2 vs. K1
These are two distinct vitamins with separate functions:
- K1 — involved in blood coagulation; deficiency may cause bruising
- K2 — regulates calcium metabolism, protecting cardiovascular health and supporting bone density
Dosage Protocol
| Goal | K2 Dose | D3 Dose |
|---|---|---|
| Maintenance | 100 mcg | 10,000 IU |
| Therapeutic | 200 mcg | 20,000 IU |
| Maximum therapeutic | 400 mcg | 40,000 IU |
Dr. Berg emphasizes pairing K2 with D3 because both work synergistically in calcium metabolism.
Top Food Sources of Vitamin K2 (Highest to Lower)
- Natto — fermented soybean product; the single richest source of K2
- Organ meats — goose liver, duck liver, chicken liver, beef liver (recommended as pâté)
- Egg yolks — pasture-raised, organic eggs preferred
- Grass-fed beef
- Emu oil
- Hard and soft cheeses — Gouda cheese specifically highlighted
- Fermented/cured meats — pepperoni, salami, pork sausage
- Grass-fed dairy — butter, sour cream, cream cheese
- Sauerkraut — contains smaller amounts of K2
Quality Considerations
For eggs, beef, and dairy, pasture-raised, organic, and grass-fed options contain meaningfully higher K2 levels compared to conventionally raised products.
