Enough for people with a deficiency, though?
He said I was probably deficient (low dairy), & that 40 p day was enough. So I guess so.
I could feel 40mg/day working straight away when I added it in - it potentiated the B12 quite a lot.

Excess B2 is quickly eliminated by urine, if you take more than that, you are just making bright yellow urine.Be sure to have enough co-factos like Mn, Mg and Fe, vit D levels are also important.Enough for people with a deficiency, though?
What kind of potassium do you take?That said, I've still got tight trapezius muscles and frequent dull frontal headaches.
Those trapezius stings are a puzzle to me, and to @picante as well.I'd thought of these as folate symptoms, but maybe I'll get out of bed and go drink some potassium and see if they go away!
@Gondwanaland The problem is, I think of these tight muscles as just the tip of my physiological iceberg. At the same time I can 'feel' my Dupytrens' aching on and off, feel the fascia in my left foot twinging, and the tension in my face tightening.
I think it's a full body request for something, and I'd like to comply. And I also think the B2 may be at the front of the line....

Hypertension
Although the etiology of hypertension is unclear, the methylenetetrahydrofolate reductase (MTHFR) gene C677T polymorphismis the main determinant of homocysteine concentrations and has been related to elevated blood pressure (a marker of hypertension) (71) and increased risk of coronary heart disease and vascular accident (72-74). Since this genetic variant leads to decreased MTHFR activity, individuals with the 677TT genotype may benefit from riboflavin supplementation. In an initialrandomized, double-blind, placebo-controlled trial in 77 healthy subjects who had been pre-screened for MTHFR genotype, riboflavin supplementation (1.6 mg/day for 12 weeks) lowered homocysteine levels in the MTHFR 677TT genotype group but not in the age-matched 677CC and 677CT groups that exhibited normal plasma homocysteine levels at baseline (75). Two subsequent randomized, double-blind, placebo-controlled trials investigated the possibility of riboflavin modulating hypertension in premature cardiovascular disease (CVD) patients (pre-screened for the MTHFR 677C→T polymorphism) (76, 77). Results showed a significant lowering of blood pressure only in the patients with the 677TT genotype supplemented with riboflavin (1.6 mg/day for 16 weeks) compared to placebo, both on initial examination (69) and when the same cohort of high-risk CVD patients was reinvestigated four years after the original trial (70). Another study investigated the effect of riboflavin in 88 hypertensive patients (but without overt CVD) with the MTHFR 677TT genotype, the majority of whom were being treated with antihypertensive therapy. At baseline, 60% of participants had failed to achieve target BP levels (≤140/90 mm Hg), despite taking three or more antihypertensive medications. The reduction in blood pressure following riboflavin supplementation (1.6 mg/day for 16 weeks) in these patients suggested that the excess risk of hypertension linked to this genetic variation could be overcome by optimizing riboflavin status (78).
@sflorence This link has valuable and fairly clear information on all the Bs and more:

But as to whether 40mg is enough, that is most likely an individual matter. For me, it seems not. When I really titrated down on the B Minus complex, which yields only about 10mg/ day of B1, B2 & B6, I found that I could 'feel' when the riboflavin ran out by the reappearance of what I'd thought of as a folate deficiency symptom--and it may actually be just that, but that I need the B2 to circulate the folate.
I'm sure you can do this, too!
I mean, they are a clear sign of high BP, but what is causing it?
You don't necessarily need to be deficient in B2 for it to help you.
Last year my BP has been consistently low at 90x60. My endo congratulated me on that I fired himActually I've got fairly low blood pressure. I was in the doctor's office just two weeks ago and it was 115 over 60. It's always been low, sometimes so low the doctor asks if I get dizzy when I stand. that said, I'm heterozygous MTHFR. This is not to say that my long-time B-Complex taking hasn't helped to keep it low, or that my focus on B2 won't help to keep it there!
Thanks. I never knew there was a connection...
Mine is really a tightening of the muscle and it remains that way for long periods of time, osmetimes making that bone at the top of the spine very sore. But iodized salt? The iodine? I use Celtic Grey Sea Salt, but then supplement 3 drops of iodine/day.those upper back stings
Has anyone experienced any B2 startup symptoms? R5p seems to be giving me some interesting side effects, mostly irritability and depression.
Edit: I think I am experiencing B1 deficiency, actually. There is another thread "no love for b2 here" and two people found their problem was B1 getting depleted from B2.
I did, what are your symptoms besides irritability and depression? Fatigue, dry eyes?
Do you eat any foods that supply B1?
Has anyone experienced any B2 startup symptoms?
Yes, from the lists I see online I eat plenty of "b1 source foods".
Absolutely. I tried to get on supplemental B2 three times before this last time when it seems to have taken, so to speak. I think it's hard to decipher what's going on until you fiddle with it over time. At least that's my experience. I keep an Excell chart of daily supps and symptoms and then study it when I'm completely flummoxed.
Patterns do seem to develop over time. Unfortunately, for me anyway, this long term experimentation and revision seem to be part of the process. Each round, I have more of the basics, more minerals, say, or more of the cofactors in place. Maybe that helps. Something must because it does change.
My snps, or my sensitive body or the bacterial/viral load I'm supporting all make it a challenge... today I feel a little philosophical. Others I feel desperate and depressed. Occasionally I feel joyful!
