Frequently Asked Questions
Can I take D3 and K2 together with other supplements? Yes, D3 and K2 are generally safe to combine with most vitamins and minerals. However, if you are taking blood thinners (especially warfarin), consult your health care provider before adding vitamin K2, as it may interfere with anticoagulant therapy.
What is the best time to take D3 and K2 gummies? Since both vitamins are fat-soluble, taking them with a meal that contains dietary fat can enhance absorption.
Are there any side effects? Vitamin D3 and K2 are generally well tolerated when taken at recommended dosages. Excessive vitamin D intake can lead to toxicity, so do not exceed the suggested serving without medical advice.
How long does it take to see results? Results vary depending on your baseline levels and overall health. Some people notice improved energy and muscle recovery within a few weeks, while bone and heart benefits are long-term.
How do vitamin D3 and K2 work together?
Vitamin D3 (cholecalciferol) is the form naturally produced by your skin when exposed to sunlight. It helps your intestines absorb calcium and phosphorus from food. Vitamin K2 (menaquinone-7 or MK-7) then activates proteins such as osteocalcin and matrix Gla protein (MGP). Osteocalcin helps bind calcium to the bone matrix, while MGP helps prevent calcium from depositing in blood vessel walls.*
This complementary action means D3 and K2 together may contribute to maintaining strong, dense bones and supporting arterial flexibility.* The MK-7 form of K2 is particularly effective because it stays active in the body longer than MK-4, providing more sustained support.
What does the science say about D3 and K2?
Vitamin D has several approved health claims in the UK. It contributes to the normal absorption and utilisation of calcium and phosphorus, normal blood calcium levels, maintenance of normal bones, normal muscle function, and normal function of the immune system. Vitamin K contributes to normal blood clotting and the maintenance of normal bones.
-
Bones: Vitamin D and K together support calcium metabolism, which is important for maintaining normal bone density.*
-
Muscles: Vitamin D contributes to normal muscle function, which can help with strength and coordination.*
-
Immune system: Vitamin D helps modulate the immune system, contributing to normal immune function.*
-
Cardiovascular health: Vitamin K is known to contribute to normal blood clotting, and some research suggests it may help maintain arterial elasticity.*
-
Teeth: By promoting calcium utilisation, vitamin K may also help maintain strong teeth.*
These benefits are particularly relevant for those with limited sun exposure, on a vegan or dairy-free diet, or looking to support their ageing bones naturally.
Why combine vitamin D3 and K2?
While vitamin D3 helps your body absorb calcium, vitamin K2 directs that calcium to where it is needed most—your bones and teeth—and helps prevent it from accumulating in soft tissues such as arteries.* This synergy is why many experts recommend taking D3 and K2 together for optimal bone and heart health.*
Many people focus solely on vitamin D, but without adequate vitamin K2, the calcium absorbed may not be properly utilised. That is why combining D3 and K2 in a single supplement is a thoughtful approach to comprehensive support.
What to look for in a high-quality D3 + K2 supplement
Not all D3 and K2 supplements are created equal. When choosing a combination product, consider the following factors:
-
Form of vitamin K2: Opt for MK-7 (menaquinone-7) for its longer half-life and sustained activity. WellYeah uses MK-7 derived from natto (fermented soya), a natural source.
-
Dosage ratio: A common effective ratio is 1000 IU (25 mcg) of vitamin D3 to 100 mcg of vitamin K2 per serving. WellYeah delivers exactly this in two delicious gummies.
-
Purity and testing: Look for third-party tested supplements to ensure potency and purity. WellYeah products are made in facilities that follow Good Manufacturing Practices (GMP).
-
Dietary compatibility: If you have allergies or follow a vegan lifestyle, ensure the product is free from animal-derived ingredients. WellYeah gummies are vegan, gluten-free, non-GMO, nut-free, and dairy-free.
-
Flavour and ease of uses: Gummies are a convenient alternative to pills, especially for those who have difficulty swallowing capsules. WellYeah gummies come in a natural strawberry flavour made with real fruit extracts.
