I know what you're talking about, b/c I've that problem w/ some B-complex supplements, too. The problem turned out not to be the amounts of each vitamin, but the ratio of niacinamide to the other B vitamins. Niacinamide promotes the formation of the relaxing neurotransmitter, serotonin. An ideal ratio of niacinamide to vits. B's 1,2, & 6 (approximately equal amounts of those) is ~20:1. That's about how it's used in some basic cellular processes. No supplements provide that, but a few go in the direction of more niacinamide. If you stay under 10mg/day of B's 1,2, & 6, between 100 - 200 mg. of niacinamide, and less Vit B 5 (pantothenic acid or pantothenates) than niacinamide, you should find your problem is solved. Vitamin B 5 is very nervous-making if you take more than 100 mg/ day for many people.
The only other issue that might be affecting you if correcting the ratio doesn't work, is that you are taking a yeast-bound B-complex supplement and are allergic to yeast. For some people, part of an allergic reaction can be increased cortisol, which sometimes masks other allergic symptoms so all the person experiences is the jittery excess cortisol feeling. Most "food-based" supplements, however healthy they might be for many people, are contraindicated for those allergic to yeast. Jarrow "B-Right" is a pretty good 2-aday, fairly balanced B-complex w/o yeast, but I would still add an extra 200 mg of niacinamide in the evening. Source Naturals "Coenzymate™ B Complex" sublinguals is similar. The Jarrow uses gelatin capsules, while the Source Naturals is vegetarian.
Believe it or not, the two I mentioned above are the best non-yeast B-complex supplements I've found, even though their ratio is more like 4:1. Everything else is worse.
If the yeast or food allergies isn't a problem, there is Garden of Life "Vitamin Code Raw B-Complex" w/ a 4.5:1 ratio (very slightly better). It has a whole bunch of enzymes, foods, probiotics and yeast included--great for those w/o allergic tendencies, but I would never recommend it to anyone who's ever experienced a food allergy since it includes so many potential allergens.
I hope this is helpful.
Is anyone else not able to fall asleep if they take an extra B complex pill? When I take one pill, all my adhd symptoms are reduced, my migraines are nearly eliminated, and all my energy is restored. I can't describe how miraculous Jarrow's Optimized B formula is to me... could this be due to my histamine levels/ under-methylation?
B complexes have literally changed my life... every aspect has improved dramatically. I can form words in my head, follow a train of thought, go to bed on time, and wake up feeling refreshed, have no migraines when getting up from bed, etc.... when I take B complexes... no sleeping aid supplement has ever worked (like melatonin), and after supplementing myself with B complex, I can feel the effects of other supplements.
