A common recommended dosage for Vitamin D3 is 1,000-5,000 IU per day, while Vitamin K2 is typically taken at doses of 100-200 mcg per day. Taking these vitamins with a meal containing healthy fats enhances absorption. It’s also beneficial to monitor Vitamin D levels through blood tests to ensure optimal intake. At 4,000IU, Puresport’s Vitamin D3 offers a high strength solution. If you require a lower daily dose, you can opt to take them once every 2-3 days instead of daily. This approach can be effective because both Vitamin D3 and K2 are fat-soluble, meaning they can be stored in the body's fat tissues and liver for future use. Sourced from marine algae, Puresport Vitamin D3 offers a high quality, naturally sourced form of this essential vitamin.
