How A Vitamin B2 Supplement Benefits You

If you’ve ever taken a vitamin B2 supplement before, you’ll already know this vitamin goes by another name: Riboflavin. Whether you call it vitamin B2, or riboflavin, this is an essential vitamin you want to be sure you’re including in your diet.

Vitamin B2 works hard in many of our crucial bodily processes, including producing energy, metabolizing other vitamins, ‘recycling’ antioxidants and facilitating healthy methylation, which is necessary for correct gene expression.

While vitamin B2 is found in a lot of food sources, riboflavin deficiency is surprisingly common. Which is why we’ve ensured it’s included in Athletic Greens to help you get the B2 you need.

Our Bodies Need B-Group Vitamins

There are eight B vitamins in total. You’ve probably heard of a number of these, like B1 (Thiamine), B6, and B12. The B-group vitamins are water-soluble vitamins that are essential for our metabolic processes.

While B vitamins are found in a lot of the foods we eat, we don’t always get the amounts we need. You could say these vitamins are a bit fragile. Their nutritional value can be reduced by cooking or processing. Also, because they are water soluble, our body only has a limited capacity to store them, and they need to be replenished regularly.

All of this means it’s easy to become deficient in B vitamins, which is all the more reason to consider a supplement to help you get enough.

Why Vitamin B2 Is So Important

Let’s look more closely at how vitamin B2 benefits the body.

Riboflavin is the raw material for two important coenzymes that bind with a protein molecule, to form an active enzyme. The ultimate outcome is that these power the body, helping it convert carbohydrates, fats, and protein into energy.

That’s a big job! But it’s not all that riboflavin does for you. Riboflavin also helps the body recycle glutathione - the body’s ‘master’ antioxidant that protects us from excess free radical damage.

On top of that, it helps you to metabolize and activate other vitamins including vitamins K, B6, and Folate (or B9). Just folate alone is essential for cellular energy production, detoxification, cancer prevention, and more. But if it isn’t metabolized, it’s not much help at all, which gives you an idea of the importance of riboflavin.

As we mentioned above, riboflavin is found naturally in a lot of foods. For example brewer’s yeast, liver and offal, almonds, wheat germ, mushrooms, egg yolks and a variety of grains, nuts, and leafy vegetables. Did you ever drink a malt drink, like Horlicks? That has riboflavin in it too! Still, many people don’t get enough of this vitamin and experience riboflavin deficiency.

What A Vitamin B2 Supplement Can Do For Your Body

If we consider the hugely important role riboflavin plays in our health, we can start to understand why a deficiency can create serious health problems, like preeclampsia in pregnant women, and low energy levels.

The benefits of riboflavin have been known for years, so it has frequently been applied for therapeutic uses and to assist with treatment of some diseases.

For example, riboflavin has been shown to be beneficial for eye health, reducing the risk of age-related cataracts forming.

It can help with preventing migraines, by supporting complex processes of metabolism in the brain, and it may be of use in lowering blood pressure and helping to increase iron absorption for people suffering from anemia.

There’s more too, riboflavin supports healthy methylation (a part of gene expression) and lowers the by-product homocysteine, which is a risk factor for cardiovascular disease and cancer. And it assists in cases of MTHFR gene mutation - a condition that causes an inability to utilize folate and eliminate toxins from the body.

You probably understand by now that this is a vitamin you don’t want to be missing out on. Which is why a supplement can help.

How To Take A Vitamin B2 Supplement

Let’s start with how much to take. The accepted daily dose of riboflavin is between 10 and 100 mg, in divided doses, although you might need a bit more from time to time if you are ill, or increase your athletic training. Riboflavin is nearly always well tolerated and is safe in pregnancy at normal doses.

As we noted earlier, most people don’t consume enough riboflavin in their diets, so could be suffering from some degree of riboflavin deficiency. And, as with all water soluble vitamins, vitamin B2 needs to be replenished on a regular basis.

This is why we’ve included it in Athletic Greens. We’re not the only ones to have figured out that riboflavin goes well with other nutritional superstars. In fact riboflavin is rarely taken on its own. People generally supplement with riboflavin as part of a more general B-vitamin complex or multivitamin energy boost.

In Athletic Greens, riboflavin works well with other B vitamins, for example with Vitamin B12 to help people absorb iron.

It also complements liver herbs such as milk thistle, globe artichoke, and dandelion root. Liver function and replenishing B vitamins are especially important for people consuming a lot of alcohol to maintain good health.

If you get your daily dose of Athletic Greens, your vitamin B2 needs are covered.

The nutritional value of B-group vitamins can be reduced by cooking or processing, and because they are water soluble, our body only has a limited capacity to store them, so they need to be replenished regularly. This is why a supplement can be a good option.


Riboflavin’s benefits for health have been researched extensively and are well understood. Its application in migraine headaches, pregnancy complications, cataracts, and cardiovascular disease is particularly well supported. And it’s even better when it’s taken alongside complementary B vitamins and liver herbs, like in our Athletic Greens mix.


As with all water-soluble vitamins, it’s difficult to take too much. You’re regularly flushing riboflavin out of your body, so you should be more concerned with getting enough of it!


Riboflavin is nearly always well tolerated and is safe in pregnancy at normal doses. That said, if you are pregnant or nursing, please consult your physician prior to taking any supplement or making a change in your diet.


There sure are! Think of the 75 ingredients in Athletic Greens as a supportive team, working together to ensure you’re getting the absolute most nutritional value out of every single one.

Riboflavin helps you to metabolize and activate other vitamins, and complements the liver herbs in Athletic Greens too, such as milk thistle, globe artichoke, and dandelion root. Absorbing vitamins and a well-functioning liver are both things you want in order to maintain good health!


Did you know caffeine may interfere with the absorption of B vitamins? Don’t worry, we’ve got your back on that one! For best results, we recommend you take one serving of Athletic Greens first thing in the morning, every day. Consistency is key, plus you’ll be getting a good dose of riboflavin before you start on your morning coffee.
