Review: Great B-Complex Supplement - The Twin Labs Stress B-Complex is the best B-supplement I've found (and I've tried a few). And on desertcart, the price is good. The potency is excellent - another reviewer posted the amounts in this supplement, which is very helpful for comparing. My husband and I both take this and notice a general feeling of well being (B-complexes are great for balancing hormones/mood) and sustained energy throughout our day. We don't need caffeine in the morning! Also, my nails and skin are much improved. I had symptoms of a deficiency (peeling lips, cracked skin on thumbs and fingers) and within a week of taking this supplement I saw a drastic change. I also appreciate the nice boost of Vit. C for energy and immune support.
Review: Best B-Complex Caps - B-12 and B-Complex supplements are widely used and well known to promote a positive mood and help prevent or reduce stress. This is one of many brands available for purchase and in my opinion it's got the best quality and price available. The glass amber medicinal jar is an excellent touch that is always preferred to purchase and store your medicines in though not 100% necessary. These pills are very large, I believe they're size "000"-- I've never had a problem downing a handful of vitamins and supplements at once and with little liquid, though this is quite uncommon. If you have ever had trouble with very large pills or capsules, you may want to rethink buying this particular brand and item and search for some smaller pills/capsules to achieve the same result. Pretty much all the popular brands of supplements containing the same formula more or less is just as good of quality but I still prefer this one despite the large pill size which, again, personally doesn't bother me one bit. I take this daily along with a few other vitamins and supplements and have no intention of stopping my daily use. I wouldn't say it's a life-changer or extremely noticeable but it definitely does help and provide an effect you can see and feel with prolonged use though it can be subtle for some.
