Vitamin D is produced in our skin in response to sunlight – with shorter daylight hours in the UK it’s important to keep levels topped up year round. Government recommendations are to supplement, especially during winter months as it’s impossible to get enough from our diet. Vitamin D helps us extract calcium from food for healthy teeth, bones and muscles. Our effervescent tablets combine Vitamin D in its active form D3 (100% NRV*) which is best absorbed with added calcium and Vitamin K (100% NRV*), another important vitamin for bone health.
