Peak Performance Advanced Vitamin D 10000 IU with All 3 Types of Vitamin K Capsules 10,000 IU Vitamin D3 and Vitamin K2, K1, MK-7 (MK7), MK4 Supplement. 60 Small and Easy to Swallow Pills
This is a good amount of vitamin D3 and the K vitamins. I get my levels checked every other year and they’ve been fluctuating between 60 and around 80 and it is because I take a good amount of these!
I try to take about 40,000 IU a week and prefer taking a few tablets here and there instead of taking one 5k every day
Vitamin Basics & Tips
Vitamin D3 works synergistically with Vitamin K to regulate calcium absorption and bone health. While D3 enhances calcium uptake from food, Vitamin K2 directs calcium to bones and teeth while preventing arterial calcification. The reviewed 40,000 IU weekly dosage (≈5,700 IU daily) aligns with common maintenance recommendations for deficient individuals, though official guidelines suggest 600-800 IU daily for most adults.
Regular blood level monitoring (60-80 ng/mL in this case) is crucial as vitamin D toxicity can occur above 150 ng/mL. The user's preference for intermittent dosing reflects emerging research suggesting weekly or monthly megadoses can be as effective as daily intake for maintaining levels. However, fat-soluble vitamins like D and K require dietary fats for optimal absorption, suggesting tablets should be taken with meals.
Combination supplements address the growing understanding that Vitamin K deficiency may undermine D3's benefits. Those with clotting disorders should consult doctors before using K-containing supplements. Always pair supplementation with sunlight exposure (10-30 minutes daily) for natural D3 synthesis.
