Dr. Lynch product Q&AUpdated an hour ago

Question
Answer
My stool is brown but has yellow liquid with it. Can riboflsvin cause this? I know it turns urine yellowish.

Hi Josh -

I've never heard of riboflavin causing this in stool. Perhaps it's your urine mixing with your stool?

Can the Riboflavin pills be opened and poured on a spoonful of applesauce for a person who can't swallow pills?

Hi Linda -

Yes they may but it won't taste good.

This is a lot of riboflavin.

Have another spoonful of applesauce ready to go that's clean.

You may want to do it in 2 bites with a clean bite in between.

Use organic applesauce as non organic apples are high in pesticides.

How much of this is R5P and how much regular riboflavin?

Hi Alice -

It is proprietary information but I can tell you it is in there in a healthy amount.

The product is predominantly riboflavin as excessive use of R5P is not needed.

Hi Dr Lynch, I am considering taking the riboflavin 400mg to reduce my homocysteine level. I have some questions hoping that you can help. I have 2 copies of C677t, and ocd too. My most recent blood work showed my homocysteine is very high which is 14.6 and Riboflavin showed 75 µg/L (200 nmol/L). I would like to know will Riboflavin help to reduce homocysteine. And is riboflavin 400mg too high in strength? I react badly to methylfolate. I am taking your Hydroxo B12 with Folinic Acid and will it be beneficial to take it with Riboflavin together? I have also bought the Optimal liposomal Glutathione and glutathione lozenges. Currently taking the Liposomal glutathione for just over 1 week now. Haven't yet noticed any difference. Thank you for your time. Best regards, Esther

Hi Esther -

The best option to support a healthy homocysteine level without using methylfolate is:

  • Hydroxo B12 with Folinic Acid Lozenges: take 1/2 to 1 lozenge upon waking
  • Riboflavin: take 1 capsule once daily with breakfast. This will support healthy homocysteine levels as it is the nutrient needed to support MTHFR enzyme function.*
  • Glutathione Plus Lozenges: take 1 lozenge upon waking to support healthy homocysteine and healthy glutathione levels.*
  • Serotonin Nutrients: take 1 capsule once to twice a day to support healthy emotions vs obsessing about things.*

Are there certain genetics or symptom presentations that would warrant more than 400 mg of Riboflavin per day?

Hi Jillian -

More than 400 mg a day of riboflavin based on SNPs? No.

400 mg a day is a significant amount.

SNPs that do warrant higher amounts of riboflavin are those that reduce the binding ability of riboflavin to the enzyme.

These enzymes are very important in the human body.

One is especially famous:

  • MTHFR

Another one that is really important to support is the one the recycles used up and damaged glutathione

  • GSR

Monoamine oxidase (MAOA) is also incredibly important - as it supports the breakdown of dopamine, norepinephrine, serotonin, histamine.

Many enzymes in the energy cycles use riboflavin.

Common signs and symptoms of riboflavin deficiency are:

  • headaches
  • irritability
  • insomnia
  • low energy
  • high homocysteine
  • angular sores in the corners of the mouth (angular stomatitis)
  • night blindness
  • nerve issues
  • high histamine

Support healthy riboflavin levels with Riboflavin supplement - and best to take in the morning with breakfast.*

Note: When taking riboflavin, it's common to experience very bright orange/yellow pee. Riboflavin colors the urine this way.

Hi Dr Lynch, I react badly to L - methylfolate. I have ocd since childhood, have 2 copies of c677t, struggling with insomnia. I am not on any ssri medication. Should I go with Riboflavin or folic acid for methylation issue? What is the difference between them? Also, from the information I gathered from listening to your sharing on YouTube, I am guessing liposomal glutathione, Serotonin nutrients and Optimal focus would help my condition. Could you please advise if otherwise? Thank you for your time!

Hi Esther -

I like how you're thinking.

Let's tweak things a little bit.

I'd do Histamine Nutrients before bed to support healthy onset of sleep.* If you're staring at the ceiling, it's because you are too stimulated and have too many neurotransmitters in your brain or too much histamine or both. Take 2 capsules of Histamine Nutrients 20 minutes before bed.

If you are having difficulties staying asleep but not falling asleep, then consider using Serotonin Nutrients before bed.*

If you are struggling with both, then I'd start first with Histamine Nutrients before bed. Then I'd use Serotonin Nutrients with your protein based breakfast.

In the morning, upon waking, I'd consider using 1/2 lozenge of Glutathione Plus Lozenges. Keep this on your bedstand.

Let's start here and see how you do.

I show need for Riboflavin from organic acids test, high glutaric acid and high homovanillic acid. I also have slow MAOA gene variation. How do I know how much Riboflavin I should be taking? 400mg seems like a lot?

Hi Pam -

Riboflavin is a much needed ingredient and if low, definitely need some.

I'd use a capsule any time of day with a meal.

You will take it when you feel you need it.

Given that labs demonstrate a need, consider taking 1 capsule daily for a couple weeks.

Then you may likely be fine to take 1 capsule as needed - say 1-3 times a week.

200mg Riboflavin 2x/day has been recommended for menstrual migraine support. Concerned SH 400mg 1x/day may be too potent. Do you think it would be possible to split the capsules? Or have any other recommendations to hit 200mg 2x/day? Thanks in advance! (Also, I've seen other brands offer Riboflavin OR Riboflavin 5' Phosphate, not as a combo. Is there a reason for the combo in your version?) Thanks again!

Hi Sam -

We mix them because they are better together. Some people need the riboflavin-5-phosphate and they don't know it - so we include it.

You'll just pee out the extra. There's no issue taking more than 200 mg at all. The only thing you'll experience is brighter yellow or orange pee and that's the riboflavin.

Your body absorbs what it needs and pees out the rest.

Menstrual migraines are also associated with the fast drop in estrogen which then drops serotonin.
https://pubmed.ncbi.nlm.nih.gov/17044842/

Consider supporting with a capsule of Serotonin Nutrients taken any time of day or night to support prevention and healthy feeling of her head.*

Do not take Serotonin Nutrients during an active migraine as it will make it worse. Only take it before to support healthy maintenance of a healthy head.*

Taking 1/2 a lozenge of Brain Nutrients in the morning or any time of day is also supportive of a healthy head and blood flow.* You may take this at the first inkling of discomfort to support a comfortable head.*

Riboflavin is actually useful to use to support a healthy head after the headache has already started. So if you're late in using Brain Nutrients or Serotonin Nutrients, then you'd use Riboflavin.

You can use Brain Nutrients with Serotonin Nutrients together if needed - or just try one or the other - depending on the day.

Try them separately at first to see how you feel.

Definitely start with just 1/4 to 1/2 lozenge of Brain Nutrients to start - upon waking in the morning - and again any time during the day if needing more - with or without food.

Same with Serotonin Nutrients - but a bite of food with this one is recommended.

I have recently (in the last week) started taking Seeking Health Riboflavin. Without changing anything else in my diet or supplement routine, I have noticed a slight bit of constipation, more fatigue, and vivid dreams. Would this be caused by the Riboflavin and if so, is there something I need to do differently? I have researched online to try to find info on riboflavin but don't see anything that indicates these symptoms.



Hi Jessica -

Riboflavin is a vitamin that supports the MAOA enzyme and others.

The MAOA enzyme reduces serotonin levels by design.

You may have lowered your serotonin levels too much by taking the Riboflavin too consistently.

Use the Riboflavin only as needed.

I believe if you take 1 capsule of Serotonin Nutrients, all your side effects from the Riboflavin may be supported.

Why?

Serotonin Nutrients supports healthy serotonin levels.
Riboflavin supports healthy breakdown of serotonin.

For now, discontinue use of Riboflavin.

Use as needed.

You may also need a lower potency of Riboflavin. Ours is 400 mg.

Possibly our B Complex Plus may be more in line with what you're looking for, or B Minus or our Multivitamin One MF.

You would pick ONE of these.

You would take with breakfast - consisting of healthy protein.

Consider using them only on days where you feel more energy is needed - and skip on days you feel good.

In health,
Dr. Lynch
