Easy-to-digest vitamin D3+K2 capsules boost energy, offer ideal 4000 IU dosage at affordable price.
Effective 4000 IU vitamin D3 with K2 combats deficiency, enhances vitality, and maintains safe toxicity thresholds in easy-swallow capsules.
This review is from Amazon.com for product:
Earth's Wisdom Vitamin D3 5000 IU with K2 (MK7) Formula. Muscle, Bone, Heart & Immune Support. Superior Absorption. 120 Capsules. Free from Gluten, Dairy, Soy. Non-GMO. Manufactured in USA.
I thought these would be hard to swallow because they're capsules, but they're by far one of the easiest pills to digest. I've definitely seen an improvement in my health. I've been vitamin D deficient my entire life, and haven't taken it seriously until recently. I feel more energized and productive. I think this dose carries the perfect amount of Vitamin D and Vitamin K2. Not too much and not too little. I personally like to take doses for Vitamin D above 2000 IU but below 10,000 IU (research has shown that above 10,000 is toxic; 4000 IU is the ideal benchmark) and for Vtiamin K2 above 100% daily value but below 175% daily value. I haven't found a better dose than this one, and for a decent price. My only complaint is that I want more quantity -- but usually I see a maximum of 120 caps for these D/K2 combos from any brand, so I won't knock down a star for this.
Vitamin Basics & Tips
Vitamin D3 and K2 work synergistically to support calcium absorption and bone health. While vitamin D enhances calcium uptake, K2 directs it to bones rather than arteries. The recommended daily allowance (RDA) for adults is 600-800 IU, but studies suggest higher doses (4,000 IU) may benefit deficient individuals. Prolonged intake exceeding 10,000 IU daily can cause toxicity, manifesting as nausea and kidney issues.
Combination supplements with K2 (MK-7 form) are preferred as they improve bioavailability. Dietary sources like fatty fish and fortified foods provide limited vitamin D, making supplements crucial for 42% of Americans with deficiency. Regular blood tests (aiming for 30-50 ng/mL serum levels) help personalize dosage. Capsule formats, like these easy-to-swallow options, ensure consistent absorption compared to tablets.
Manufacturers often cap combo supplements at 120 capsules due to K2's stability concerns. Users should pair supplements with magnesium-rich foods for optimal metabolism. Morning intake with fatty meals enhances absorption, while avoiding calcium blockers like phytates maximizes benefits.
