The science behind Inessa Multivitamins
Why Do We Need Multivitamins?
Multivitamin supplements are an important way to ensure optimal daily nutrition and support general health and wellbeing. However, not all products are equal. Inessa Advanced Multivitamin is a professionally formulated multivitamin and mineral providing optimal levels and forms of the right nutrients, because quality matters to your health.
Optimal nutrition is vital to ensuring health and wellbeing, and a well-balanced diet remains the most important way to ensure adequate intake of essential vitamins and minerals. However, due to modern dietary habits, suboptimal intakes of nutrients are very common, making nutritional supplements an important consideration for most people.1
Multivitamins are not intended to replace healthy eating, but instead leading experts recommend that they are used as part of a healthy diet and lifestyle.2 Importantly, multivitamins are proven to be very safe, can help fill important “nutritional gaps,” and have well demonstrated health benefits.3
How do we compare?
Multivitamin products vary greatly, with important differences in the nutrients they contain, including the number of nutrients, the dosage level, and the type of nutrients. Inessa Advanced Multivitamin provides 26 nutrients, at levels that experts recommend to ensure optimal nutrition, with forms of nutrients that are more effective than others. The result is simply a multivitamin that provides the right nutrients, in the right amounts.
A board-spectrum of vitamins and minerals is important for providing optimal intake of a wide range of vital nutrients each day, but products can differ greatly. The following table shows you just how much leading multivitamin and mineral products can vary in nutrient content and levels:

The purity of your product is also important, which is why we don’t use any unnecessary additives or chemicals such as titanium dioxide, flavourings or colourings.4 5
What Are Active Forms of Nutrients?
The type of nutrients in your dietary supplement can be very important, improving the nutritional quality and benefits of the product. Inessa Advanced Multivitamin provides the best possible forms of various nutrients. Excellent examples of this are the forms of folate, vitamin D, and vitamin K used in our product.
Folate is the name of a family of different forms of a vitamin, but these different forms have different activity in the body. Folic acid, the most common form used in multivitamins is not the active form of the nutrient, and because of genetic differences in folate metabolism, is not the most effective form for many people. L-5-methyltetrahydrofolate (5-MTHF), on the other hand, is a form of folate that is more natural and better utilized by the body.6
Vitamin D is available in two forms as a dietary supplement, vitamin D2 and D3. Vitamin D3 is a more active form of vitamin D and is more effective at improving your vitamin D levels than vitamin D2.7 The superiority of D3 may also extend to health effects, with evidence suggesting it is better for you as well.8
Vitamin K is a term for a family of related vitamins that have important differences in activity. A number of types of vitamin K are used in dietary supplements, however a particular form of vitamin K called menaquinone-7 (MK-7) is much better absorbed and considered a superior form of vitamin K for optimal nutrition.9
What are optimal doses?
Most people are unaware that, with few exceptions, the recommended daily allowance (also known as the RDA, or Nutrient Reference Value; NRV in Europe) is the minimum amount required to prevent an extreme deficiency, and not a level for optimal health.10
In fact, the RDA has been criticized for being un-scientific and an inadequate reference for our nutritional needs.11 A major weakness of the RDA level is that it is unlikely to provide the level of nutrition that will help prevent the major illnesses in society today.12
To provide you with the best multivitamin and mineral, Inessa Advanced Multivitamin is based on levels of nutrients that have been determined by world-leading research, including recommendations for an optimal daily intake of 500mcg for vitamin B12,13 2000 IU per day of vitamin D,14 100mcg of vitamin K,15 400mcg of folate,16 1000mg of boron,17 150mcg of iodine,18 20mg of zinc,19 and 55ug of selenium.20
No unnecessary nutrients
Perhaps the most overlooked qualities of a good multivitamin and mineral product, is the absence of unnecessary nutrients. Some are impossible to provide in a once-daily tablet in a meaningful amount, while others are not needed and may even have unwanted effects.
A condition that causes a build-up of excess iron, known as hereditary hemochromatosis, is relatively common, and even if you do not have hemochromatosis long-term dietary iron excess could contribute to chronic health problems.21 Like iron, long-term copper excessive intake of the mineral copper is also associated with potential adverse effects.22 For these reasons we recommend that people without iron or copper deficiency take Inessa Advanced Multivitamin, which is iron-free and copper-free.
Multivitamin supplements frequently contain minerals in amounts that are nutritionally meaningless. These minerals - potassium, calcium and magnesium - are known as “macro” minerals, because they are required in large, amounts, much larger than most multivitamins provide. Requirements for these nutrients are at least 320-420mg per day for magnesium,23 1200mg for calcium,24 and 3510mg for potassium.25 These levels are impossible to fit in a single tablet, and are best achieved with a separate dietary supplement and/or food. Inessa Advanced Multivitamin has no magnesium, potassium or calcium because no once daily multivitamin can provide therapeutic amounts.
Beyond a multivitamin
A nutritional advantage of Inessa Advanced Multivitamin is that it provides more than just vitamins and minerals, with the addition of the macular carotenoid lutein, and coenzyme Q10. These nutrients go beyond simply providing essential vitamins and minerals to support you with an important phytonutrient and nutritional co-factor, for better nutrition.26 27
