Why does my urine turn bright yellow after taking these tablets?
This is due to the riboflavin. Your body uses what it needs and excretes the rest through the kidneys, which gives your urine a bright yellow color. This is harmless.

You hear a lot about magnesium and vitamin D, but vitamin B2 rarely gets the attention it deserves. Yet riboflavin, as the substance is officially called, plays a role in dozens of processes in your body. Vit4ever processes 250 mg of riboflavin per tablet, a dosage that far exceeds what you normally get through food. A jar contains 365 tablets: with one tablet per day, you are set for a whole year at once, without having to think about reordering halfway through the year. And because it is a single supplement, you know exactly what you are getting, without it getting lost among ten other substances in a multivitamin.
Riboflavin contributes to a normal energy-yielding metabolism and to the normal functioning of the nervous system. In addition, it contributes to the maintenance of normal mucous membranes, normal red blood cells and normal skin. Riboflavin also contributes to the maintenance of normal vision, to a normal iron metabolism and to the protection of cells against oxidative stress. Riboflavin also contributes to the reduction of fatigue and tiredness.
Vitamin B2 is water-soluble. This means that your body cannot store a large supply like it can with vitamin A or D. What you do not use, you simply excrete again. Riboflavin is mainly found in dairy, meat, eggs and whole grain products. With 250 mg per tablet, you are well above the reference intake of 1.4 mg. A fixed tablet gives the same amount every day.
Riboflavin belongs to the group of B vitamins, together with B3 and B6, among others. Some people deliberately choose a separate B2 supplement instead of a broad multivitamin because they want to specifically supplement this one vitamin.
The tablets from Vit4ever are completely plant-based. In addition to riboflavin, they only contain microcrystalline cellulose as a filler. No artificial colors, no flavorings and no unnecessary additions. That makes the list of ingredients short and clear, exactly what you want to see on a label. Many people wonder if a high dose of B2 also causes any side effects. The best-known effect is that it can turn your urine bright yellow. That is harmless and simply the result of the excretion of the excess through the kidneys. Do you wear contact lenses or are you just curious why your toilet looks different after swallowing a B vitamin: this is the explanation.
With 365 tablets in a jar, you only need to order once a year if you take one tablet daily. Convenient if you do not want to think about reordering every month. Every production batch is independently checked for content and purity, so you know that there is actually 250 mg of riboflavin in every tablet. By the way, the compact tablet form makes it easy to take with you when you are on the go or do not eat in the same place every day. Some people keep a small jar at work or in a bag, so that skipping a tablet does not easily happen. This keeps it simple: one tablet with water, every day around the same time.
Each tablet provides 250 mg of riboflavin. The reference intake is 1.4 mg per day.
With 1 tablet per day, a single order will last you an entire year.
Only riboflavin and microcrystalline cellulose. No colorings or flavorings.
Each production batch is tested for content and purity, ensuring that the dosage matches the label.

This is due to the riboflavin. Your body uses what it needs and excretes the rest through the kidneys, which gives your urine a bright yellow color. This is harmless.
Riboflavin is water-soluble, so your body doesn't store it like vitamin A or D. Any excess leaves the body through urine. However, do adhere to the recommended daily dosage of 1 tablet.
The reference intake for riboflavin is 1.4 mg per day. This tablet provides 250 mg; that is the dosage the manufacturer has chosen for this single supplement. Stick to 1 tablet per day.
Riboflavin is found mainly in dairy products, eggs, meat, and whole-grain products. A dietary supplement complements a varied diet. If in doubt, it is best to discuss this with your doctor or a dietitian.
Riboflavin contributes to normal energy-yielding metabolism, the maintenance of normal red blood cells, and the protection of cells from oxidative stress. In the body, it is converted into FAD and FMN.
Chemically, it is the same substance. The difference lies in the amount and the convenience. Through food, you usually get a few milligrams, while this tablet provides 250 mg per piece. A tablet provides the same amount every day.
