Formula works well for me

The ingredients work well for me. The B 12 is made from a natural source and it is at higher than average dose of 1,000 mg, (natural source of Methylcoba... .) I had a B12 deficiency, so far down that I had enemia. After taking the natural B12 ( with larges dosages than just the multi), for 3 months it is now shown as "high."I've also learned that Thiamin, B1, is also often low in people. So I'm very glad this multi has a high dosage of 60 mg, that is 5,000% of the "daily value."Some multi B vitamin products show the same amount for just about every vitamin listed, like all 50 mg. However this vitamin is more specific.I appreciate it that all the amounts are relatively high. A good bargain.

Solid B Complex - With A Caveat - Read...

For the money, this B-vitamin complex is great! A fraction of the cost of other "high-end" formulas. Doctor's Best QC is notably down from what it was, though. So, heads up.That said, the downside is the EXTREMELY exaggerated levels of B3 and B12. For some, this form of B6 will actually DEPLETE natural B6 levels (which aid in serotonin - melatonin balance / production, sleep cycles), as it has to be converted into a usable form by the body. And while the extra vitamin C (ascorbic acid) aids in metabolizing B vitamins, it can also cause stomach upset and rank flavor.Take those into consideration, ESPECIALLY if you combine this with a multivitamin that also contains B vitamins. Too much B12 and B6 can cause anxiety, slow metabolism, restlessness, and even a "buzzing" sensation in the nervous system. Why? Overload.PROS: Best forms of Biotin and Folic Acid (Folate). Best forms of all B vitamins, with exception to B6. If you take melatonin (with B6) at night, you can counter the B6 depletion, but be ready for your body to try to flush out the excess, as most B vitamins are water-soluble.CONS: An insane amount of B6 and B12; 3-4 times what the average adult can realistically use. Overload happens and flushing, usually. Urine will turn greenish color, which is GOOD; it means that the body is discarding excess that it doesn't need. Here's the deal. If you take B vitamins to help with sleep and overall mood, these excesses can actually go against why you're taking them to start with. People with mal-absorption issues require higher doses to achieve the same benefit. However, Doctor's Best needs to dial back these levels to a reasonable level.Smack the "Helpful" button if this has helped you in any way? Thanks!

Great brand… I take it in the morning for a good boost of energy.

Easy to swallow—no negative side effects if you eat before taking!

Trusted brand and easy way to get B vitamins for better energy throughout the day. I’m happy it includes niacin because that seems to help with energy production. I haven’t noticed a strong smell. I always eat breakfast before I take these to avoid a niacin flush. Very good.—————————-6 months later and I’m still using these. I try not to use them every day, I’ll take a couple weeks off sometimes to ensure that I’m not overdoing it.

Used for years! Feel the kick!

Well, these things are the B supplement we have been waiting for! My therapist taught me a bit about methylation and how a great many people do have issues with it. So here we go on the hunt. After trying a couple of other supplements with methylated B vitamin complex, this one delivers the same great results as the other brands while being an excellent value. My meds really drain me and eating too much makes me sleep. This just helps me with everything. I have begun to insist that my husband take this daily as well. If I don't I can tell I forgot! Now this will make your urine so yellow it is a bit frightening. I also have been told by a few clinicians not to have this supplement after 6 pm. because it can exacerbate insomnia.
