I have struggled with several B-vitamin deficiencies for several years. That is not just my opinion - there were actual physical symptoms, and the deficiencies were diagnosed both on the clinical symptoms and regular, quarterly blood tests performed in a hospital laboratory. I have lost count of the number of supplements I have tried. Most of them were somewhat effective, but never were completely satisfactory. When I started B Complex Plus, I doubled the daily dose for one week, then dropped back to a double dose every other day, and the regular dose every other day for a week, and then began taking the recommended daily dose.<br /><br />(By the way, I am not suggesting that anyone exceed the recommended dose: I would not have done it without strong evidence of a deficiency.)<br /><br />At the end of two weeks, I had my regularly scheduled blood tests. I had a feeling they would be better than usual, because all of my clinical symptoms had clearly improved. There was an across-the-board improvement in all the areas evaluated, after only 15 days! My doctor said that since there are other high-potency B-vitamin supplements on the market that do not usually yield such quick, impressive results, it is obvious that the way these vitamins are compounded has produced a supplement with a remarkably high bioavailability.<br /><br />We are going to be repeating the tests in 30 days, rather than waiting for another 90, and I am crossing my fingers, hoping that the improvements are sustained. Besides the obvious reasons for that hope, there is also the fact that these vitamins, even at double doses, did not cause nausea or any other gastrointestinal discomfort whatever. And anyone who has done much shopping for high-quality vitamin supplements knows that the prices are often ridiculous. In fact, I almost did not try the Seeking Health B Complex Plus, because I was so accustomed to absurdly high prices that I resisted the idea that any supplements so reasonably priced could be any good. I am very happy to admit that I was wrong about that!<br /><br />I may update here after the next round of tests.

After battling with my weight and extreme fatigue for as long as I can remember I really thought that there was nothing I could do about it. I was diagnosed with hypothyroidism and prescribed Synthroid, which helped with other symptoms, but I still could not lose weight and was extremely tired. My endo suggested I may have the MTHFR gene mutation and suggested I cut out all enriched grain products and take a bioavailable b-complex vitamin. It worked! I started taking this vitamin and stopped eating enriched grains and within days I had more energy than I have had in a long time. I also started noticing that I was not very hungry, which lead me to discover that b-complex vitamins can also be an appetite supressant, so that was a nice surprise. I have not tried other b-complex vitamins, so I can't say how these compare to other brands, but I can tell you these work!

I used to think of this as a company with high standards. However, I suspect their quality control is not up to snuff. My bottle of B Complex Plus was sometimes okay, but then I twice had a severe niacin flush reaction which lasted for half an hour each time (I'm familiar with that reaction). This suggests that the blend was not thoroughly mixed, AND it makes me wonder what I got in the other pills.<br /><br />The company did offer a refund. Surprisingly, though, they did NOT ask for any other info, such as the batch number. They should be more interested in tracking down who was responsible for this error.<br /><br />Sadly I will no longer be able to trust this company's products.

I have the gene mutation mentioned in the product description. Ive been chronically exhausted for years. My doctor recommended a product like this years ago and i finally got around to taking it. It feels like ive done cocaine without any of the negative side effects. Life changing. Dont do drugs kids. Just take your vitamins.

Great products. Almost all B vitamins produced use folic acid, a synthetic form of folate, while this brand uses true folate. Most of us, meaning our cells, can't use folic acid, in fact it can be down right harmful to some like my wife. After seeing a huge improvement in my wife's health from diet change and taking Seeking Health vitamins I began taking them as well.<br /><br />Sure enough, my energy level improved. For years I have needed or felt I needed an afternoon nap. My energy level was inconsistent, along with my mental acuity. These vitamins are great. I am used to taking higher end vitamins like New Chapter and Garden of Life, but I have switched permanently to Seeking Health. I have heard Dr. Lynch on podcasts and now use his products and I am truly convinced these are the best vitamins money can buy.

I have purchased this vitamin complex from Amazon many times. This is my favorite B complex and I recommend it to lots of people. I was diagnosed with MTHFR Genetic condition and need to be very conscious of my B vitamin intake.<br />If you are new to Buying B vitamins I would not recommend taking a single B vitamin. I always get a B complex.Too much of one particular B vitamin is not healthy for you and may cause and balances and efficiencies and other vitamins. I started taking a B complex regularly when I was diagnosed with having large blood cells. I was very sick at the Time and practically bedridden. Good B vitamins became essential to my health.
