It contains all the important vitamins and trace elements you need, but it also combines them with a full spectrum of phytonutrients in order to provide advanced immune support.

Xtend is a mix of natural and artificial/synthetic ingredients. Most of the ingredients are completely natural, mostly plant extracts and plant powders. Xtend+ is the all-natural version with easy-to-swallow vegan capsules. Natural ingredients are not only more expensive than their synthetic counterparts, they also take up more space, which is why there are fewer vitamins in Xtend+ while still offering the same function and health benefits as Xtend.

Xtend is intended for adults and children over 12 years of age. If you’re taking blood thinning medication and would like to start taking supplements containing vitamin K, you should consult a doctor first. Vitamin K is known to compete with anticoagulant medication, and your doctor should monitor your blood-clotting time and adjust the dose of your medication if necessary.

Because this nutrient contributes to normal immune system, bones, joints, muscles and teeth. More than one billion people worldwide are estimated to have a vitamin D deficiency. Lifestyle, age, clothing, sunscreen routine, skin type and even where we live may compromise our body’s ability to produce vitamin D from the sun. Just like our fatty acid profile, our vitamin D levels are unique. Vitamin D testing makes it easy to monitor our levels throughout the year and adjust it accordingly. ZinoShine+ is a natural food supplement that combines vegan vitamin D3 in its most bioactive form from wild-harvested lichen, and broad-spectrum magnesium. 

Research consistently shows that magnesium helps to regulate Vitamin D (as well as other minerals such as phosphorus and calcium), and when you increase your vitamin D intake, you should make sure that there is sufficient magnesium within the system as well.

Each tablet in a ZinoShine+ blister pack contains 12.5 mcg vitamin D. Other products on the market might contain up to 50 or 100 mcg. The reason why our tablets don’t have the same high content is because we don’t want you to consume more vitamin D than what your body needs. Our supplements are always tailored to your unique needs. When it comes to Vitamin D, there are a range of individual influences on a person’s status determining how much vitamin D you need to take. That is why we always ask you to take a blood test first to measure your current vitamin D levels. Based on your results, you can then start supplementing to maintain or top up your levels.

The Vitamin D Test is an at-home, dried blood spot test from Zinzino’s portfolio of scientific health tests. The results allow you to monitor your levels of the ‘sunshine nutrient’ throughout the year and determine whether you need to improve your vital vitamin D levels. As the individual vitamin D status is constantly changing, along with lifestyle and seasonal variations, you need to test your levels every four months, especially if you live in a colder area with long winters. The Vitamin D Test makes it easy to monitor and maintain your optimal levels. 

The vitamin D blood spot test captures the vitamin D levels in your body from food, supplements and skin synthesis, to determine if your levels are too high, just right or too low. While there are multiple ways to discover vitamin D levels, the most accurate method is a 25-hydroxyvitamin D test. It measures the 25(OH)D, also called calcidiol, in your blood. Vitamin D must go through several transformation processes before your body can use it and calcidiol is the form that your body first converts vitamin D into when it gets to the liver. 

Yes. This is perfectly fine to do with all our immune supplements to facilitate consumption.
