Vitamin B2 refers to a family of water-soluble flavin vitamins that are critical for metabolism and energy generations in the aerobic cell, through oxidative phosphorylation.
These compounds are synthesized in plants and microorganisms and occur naturally in three forms: the physiologically inactive riboflavin, and the physiologically active coenzymes flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). FAD accounts for about 90% of the total riboflavin in tissues. Because of their capacity to transfer electrons, FAD and FMN are essential for proton transfer in the respiratory chain, for the dehydration of fatty acids, the oxidative deamination of amino acids, and for other redox processes.
The effects of riboflavin deficiency on growth and development have generally been explained in terms of these functions. Flavin derivatives ingested with the diet (FAD, FMN) are dissociated by gastric acid from their protein binding, transformed by phosphatases to riboflavin, and absorbed in the small intestines. The reconversion of riboflavin to the coenzymes FMN and FAD occurs in the cytoplasm in many different tissues.
Vitamin B2 is involved in the metabolism of folate, vitamin B12, vitamin B6, and other vitamins. Plasma vitamin B2 is a determinant of plasma homocysteine level, which is associated with cardiovascular disease, pregnancy complications, and cognitive impairment. \
Recent studies have suggested that riboflavin may play an important role in the determination of cell fate, which would have implications for growth and development. Specifically, riboflavin deficiency impairs the normal progression of the cell cycle, probably through effects on the expression of regulatory genes, exerted at both the transcriptional and proteomic level.

Vitamin B2 deficiency is common in many parts of the world, particularly in developing countries. Several studies have indicated that vitamin B2 deficiency may be widespread in industrialized countries as well, both in the elderly and in young adults. Dietary deficiency of riboflavin is characterized by lesions on the lips and the angles of the mouth, fissured and magenta-colored tongue, corneal vascularization and normocytic, normochromic anemia.
Skin lesions include red scaly, greasy patches on the nose, eyelids, scrotum, and labia and seborrheic dermatitis. These symptoms are a consequence of oxidation stress due to the accumulation of lipid peroxides. Vitamin B2 deficiency leads to reduced activity of the flavin-containing enzymes (glutathione reductase and glutathione peroxidase) which, in turn, allows these peroxidase to express their deleterious effects.

I have been using Healthmatters.io since 2021. I travel all over the world and use different doctors and health facilities. This site has allowed me to consolidate all my various test results over 14 years in one place. And every doctor that I show this to has been impressed. Because with any health professional I talk to, I can pull up historical results in seconds. It is invaluable. Even going back to the same doctor, they usually do not have the historical results from their facility in a graph format. That has been very helpful.

You can combine all test reports inside your Healthmatters account and keep them in one place. It gives you an excellent overview of all your health data. Once you retest, you can add new results and compare them.
If you are still determining whether Healthmatters support your lab results, the rule is that if you can test it, you can upload it to Healthmatters.
While we work with many popular labs, we welcome reports from lots of other places too.
It's as simple as this: if you can get a test done, you can upload it to Healthmatters and we can interpret results from any lab out there. If laboratories can analyze it, we can interpret it.
If you're on the hunt for a specific biomarker, contact us and we'll add it to our database. Anything from blood, urine, saliva, or stool can be uploaded, understood, and tracked with your Healthmatters account.
The Complete Plan ($15/month) is perfect for individuals who want ongoing access to their health data. It includes unlimited lab imports, visual tracking, custom ranges, result explanations, full account exports, and secure sharing — all with a simple monthly subscription. You can cancel anytime and restart your plan whenever you're ready — your data will still be there waiting for you. You can also upgrade to the Unlimited Plan at any time, with the cost prorated based on what you've already paid.
The Unlimited Plan ($250 one-time) is also designed for individuals but offers lifetime access with no ongoing subscription. You'll get all the same features as the Complete Plan, plus a larger initial data entry allowance (10 reports), making it a great choice if you prefer a one-time payment and long-term use without monthly fees.
In short:
There are two ways to add your test reports to your Healthmatters account. One option is to input the data using the data entry forms. The other method is to utilize our "Data entry service."
Our data entry forms offer an easy, fast, and free way for you to input the reports yourself. Self-entry allows you to add an unlimited number of reports at no cost. We make the self-entry process user-friendly, providing dozens of templates that pre-populate the most popular laboratory panels and offering instant feedback on entered values.
For those who prefer assistance, we offer a "Data entry service" to help you input your data. Simply attach an image or file of your lab test results, and a qualified team member from our data entry team will add the results for you.
We support various file types, including PDFs, JPGs, or Excel. This service is particularly useful if you have many reports to upload or if you're too busy to handle the data entry yourself.
Our Data Entry Service is for when you don't want to manually type in your lab results yourself. You simply upload your report (PDF, image, or screenshot), and our trained team enters the information into your Healthmatters account for you — accurately and neatly organized, ready to view in graphs, tables, and timelines.
The $15 per report covers the time and care it takes for a real person to review your file, make sure each result is entered correctly, and double-check for accuracy. This ensures your health data is precise and easy to work with — without you having to spend the time doing it yourself.
Prefer to do it yourself? You can always use our free self-entry tool to add results manually — it just takes a bit more time and attention.
For users on the Complete monthly plan, the first report is entered free of charge, and each additional report incurs a fee of $15.
Unlimited account holders enjoy the entry of ten reports without charge. Subsequent reports are subject to a $15 fee per report.
Additionally, users on the Complete plan can upgrade to a yearly subscription from the account settings. The annual subscription includes a data entry service for five reports.
All professional accounts allow you to import and onboard an unlimited number of clients and their lab results. The distinction between professional plans lies solely in the data entry service.
The Pro Monthly Plus plan is priced at $75 per month and includes a data entry service for five reports each month. Additional reports can be self-entered at no extra cost or, if preferred, you can use our data entry service for an additional fee of $15 per report.
The Pro Monthly plan is priced at $45 per month and does not include a data entry service. Self-entry is free for an unlimited number of reports, and you can opt for the data entry service at a fee of $15 per report.
You also have the option to upgrade to higher monthly or to annual plans, which come with substantial discounts. All upgrades can be done directly from your account.
Simply log in and navigate to your account settings to cancel your subscription. Scroll down to locate the 'Cancel' button at the bottom of the page.
