WHY OUR VITAMIN D3: Supports immunity, muscle function, bones and teeth, our small and easy to swallow, gel capsules provide the active form (cholecalciferol) of vitamin D for best results. Studies indicate many of us are low or deficient in this vital nutrient which is why national guidelines recommend we all supplement vitamin D from at least September to March to avoid deficiency, but for some the advice is year round supplementation. MAINTENANCE OF BONES: The benefits of vitamin D3 are well documented for maintaining healthy bones and teeth, but it is also needed for healthy muscles and the normal function of the immune system. It is especially important for the normal growth and development of bones in children. With severe deficiency, symptoms such as chronic and widespread pain, muscle weakness, fatigue, osteoporosis and depression can occur. THE SUNSHINE VITAMIN: Vitamin D is an essential fat-soluble nutrient which is unique in that the main source is not dietary, but sunshine, as our body produces this vitamin in the skin from cholesterol in response to UV rays. The production of vitamin D in our bodies can be affected by factors such as the season, weather, latitude, time of day, use of sunscreen, colour of skin, age and lifestyle. GOES WELL WITH: The gelatine capsules are suitable for Halal and Kosher diets and can be paired with other Higher Nature products including Super Potency Fish Oil, Super Magnesium, Vitamin K2, Probiotics and MSM Glucosamine Joint Complex.
