D3 in the Immunity 365 kit: 15 sprays provide 11 µg
Immunity 365 · Your questions
The key figure to remember for the Vitamin D3 in the Immunity 365 kit is precise: a quantity of 15 sprays provides 11 micrograms, also indicated by the symbol µg or the abbreviation mcg. The nutritional value for a specific number of sprays and the instructions regarding frequency of use are separate pieces of information: read both on the packaging. This clarification avoids applying the instructions for other sprays to the D3.
Three numbers, three different pieces of information
In the Biomed family, you will encounter the 150 ml format, the stated concentration of 1100 ppm, and the nutritional data of 11 µg per 15 sprays. The first indicates the volume of the package, the second a concentration, and the third the value stated for 15 sprays. To determine how to use the product, start from the confirmed nutritional data, without trying to calculate it using a proportion based on the ppm.
The abbreviation mcg and the symbol µg represent the same unit: the microgram. They should not be confused with milligrams. If you are comparing packages that use different units, ask your pharmacist for help before deciding how to combine them. A unit error can significantly change the meaning of an apparently small number.
The role of vitamin D
Vitamin D contributes to the normal function of the immune system and the maintenance of normal bones and muscle function. We are talking about physiological functions, not a guarantee of avoiding infections, correcting all fatigue, or replacing therapy. The nutritional benefit must be distinguished from a promise regarding personal results.
The amount of vitamin D required also depends on your individual situation. The product data does not determine whether you have a deficiency or whether you should modify a prescribed supplement. If you already have medical guidance, maintain that reference and show the packaging before adding the D3 included in the kit.

Quantity per spray and frequency of use
For the frequency of use for the D3, follow its label. The nutritional reference of 11 µg concerns 15 sprays and does not, by itself, establish how often to use the product. To make the reminder clear, write the name D3, the frequency indicated on the label, and the value for 15 sprays on the same line. Always keep the label as a complete reference.
Do not decide on larger quantities on your own just because you spend little time in the sun or because winter is coming. Using a larger format does not change the instructions. If your routine includes other products with vitamin D, the total quantity must be evaluated before adding a new package, not after having started.
Comparing single D3 and kits
If you only want the D3, the individual product page allows you to consult the format and terms of purchase. If you are examining Immunity 365, also consider the role of the other three components: C, Echinacea, and Silver are not a replica of D3 and do not automatically follow the same dosage.
Purchasing a kit can make it more convenient to receive a pre-assembled selection, but it does not make every substance necessary for every person. A precise decision can also be to choose only one package. Comparing products helps you understand what you are receiving; comparing them with a professional helps you determine what is appropriate for you.
Three situations you may find yourself in
You already take a D3 once a week
You have a prescription with a frequency different from the one indicated on the Biomed spray. Do not just compare the number of units on the package and do not add the 15 sprays as if they were independent. Take both labels to your doctor or pharmacist, along with the frequency you are following. The data referring to 15 sprays of the new product is useful precisely to make the assessment clear. Its presence in the kit does not change the prescribed plan and does not authorize you to replace one formulation with another based on personal calculations.
You use the same reminder for all sprays
You had prepared a single alarm and wrote to repeat everything two or three times. For D3, correct the reminder: the stated value is 11 µg per 15 sprays; consult the label for the frequency of use. Keep a separate line for each product and do not copy the frequency from one bottle to another. This small change makes the system more precise without complicating it. When you read new instructions, update only one record so that old sheets with different dosages do not remain in circulation, which can create confusion.
You want to understand a different label
You are comparing the Biomed D3 with another package and find different units. Before deciding, identify what quantity each piece of data refers to: a drop, a tablet, a daily dose, or a volume. Do not simply compare the larger numbers printed on the front. You can photograph the tables and have your pharmacist read them. The useful question is which intake corresponds to the actual instructions and how it fits into your situation. The Biomed guide helps you recognize the terms, while your personal assessment requires the full picture.
