We often recommend D Lux by Better You. This product is tasty & easy to take. Just spray under the tongue for increased absorption. It has the added benefit of being suitable for vegetarians & 100% natural ingredients. Vitamin D3 is a fat soluble vitamin, so DLux 1000 is oil-based (coconut oil as a medium chain triglyceride), so enhancing it's absorption within the body. - Shona Wilkinson, Head Nutritionist Vitamin D is a vitamin & pro hormone that is synthesised by the body when our skin is exposed to UVB sunlight. Less than 10% of our supply comes from natural foods. As our bodies were developing, many thousands of years ago this was a simple & straight-forward process. Vitamin D (for humans this is D3) is essential, along with magnesium, to absorb calcium. Without D3 & magnesium, calcium is simply not soluble. It will not enter our bones & settle in the soft tissues around our joint, in our muscles & in our blood cholesterol. Calcium is very good for us but only if we can absorb it. Vitamin D3 is a fat soluble vitamin, so we have developed D Lux 1000 to be oil-based (using natural sunflower oil), so increasing it retention within the body. By applying it directly into the mouth, ideally under the tongue, it is absorbed directly into the blood system rather than having to be processed by the digestive system & major organs. This ensures no loss during the absorption process. The solution has been microemulsified to ensure the particle size is optimal for absorption in this way. Ingredients: Purified water, xylitol (natural sweetener), cholecalciferol (vitamin D3), sunflower oil, lemon oil, natural preservative: potassium sorbate. Dosage Guide: A single spray directly into the mouth (ideally under the tongue) or as recommended by your health practitioner. Can be sprayed into a drink if preferred. 100 measured doses, 3 months supply. DLux 1000 is an award winner!
