Good Quality gentle on stomach
I recently purchased these Vitamin B12 vitamins and have been very happy with them so far. The vitamins are easy to take and gentle on my stomach, which is very important to me since this is the reason I need a little help with Vitamin B12 boost. After taking them consistently, I’ve noticed improved energy levels and less fatigue throughout the day. The quality of the product seems excellent, and the packaging arrived in perfect condition. I also appreciate that there is no unpleasant aftertaste. Overall, I’m very satisfied with this purchase and would definitely recommend these Vitamin B12 vitamins to anyone looking for a good-quality supplement.

Dietary supplements are designed to enhance a well-balanced diet and promote a healthy lifestyle. The best ways to get vitamins, minerals, antioxidants, and to live a happy healthy lifestyle are: eating a healthy balanced diet including more vegetables and fruits, staying hydrated, exercising, weight management, stress management, not smoking, vaping, or using tobacco products, limit alcohol consumption, have a positive outlook, and get plenty of quality sleep. Supplements do not cure anything, but they may fill gaps you are missing from your diet or dietary restrictions. Remember supplements are not for everyone. Some people should avoid using supplements due to health conditions or other factors. For instance, it is unknown if certain supplements are safe to use while pregnant or breastfeeding. If you are unsure if you need to take a supplement: Consult your doctor, registered dietitian, pharmacist, or healthcare provider before starting any supplement(s). A healthcare professional will ensure that the supplements do not interfere with any prescribed medications, thus preventing potential risks or complications. Your doctor can run tests which can identify lack of vitamins, minerals, or any hormonal imbalances. During a routine blood check my doctor reported my vitamin B was low and I needed to take B-Complex supplement. I researched and tried other B-Complex supplements, and I did not feel any difference. So, I switched to Thorne B-Complex #12. Excellent B-Complex Supplement! I have been using Thorne B-Complex #12 for six months now, and I can confidently say it is one of the best B-vitamin supplements I have tried. The combination of active B12 and folate makes a noticeable difference in my energy levels and mental clarity. Additionally, during my next visit, my doctor reevaluated my blood and my vitamin B was in normal range again. I appreciate that Thorne uses high-quality ingredients without unnecessary additives. The capsules are easy to swallow, and I have not experienced any digestive discomfort, which can sometimes happen with other B-complex supplements. I also love that it is third party evaluated for purity and potency, giving me peace of mind about what I am putting into my body. What I like about the product is: 1. They use quality ingredients. 2. No digestive issues. 3. They are third party tested. What I do not like and what prevents the product from receiving a perfect 5-star rate: 1. The product is higher priced than other B-Complex supplements. If you are looking for a clean, effective B-complex supplement, I highly recommend this one!

Best out there
Thorne. That’s all that’s needed to be said. They make the best supplements hands down. They have changed my life for the better and this B-Complex starts working on day one. No nausea, no side effects, just seems to work. Have been taking one a day.

The only B Complex I can take.
I always suffered with the Bs. I'm pushing 60 and really needed them. I did an allithiamine (B1) routine for a few months then tried this one and I could take it -- daily -- with no gut issues or misery. I really like the Thorne brand. They have a few different B complexes and only this one agrees with me.

Energy in a Capsule—Goodbye Afternoon Slumps!
Thorne B-Complex #12 has been a total game-changer for my energy levels. It’s like a secret weapon for those dragging afternoons—I feel more focused and less like I need a caffeine IV to get through the day. The active forms of B12 and folate make a big difference, especially if your body struggles to process the synthetic versions found in other supplements. I also love that it’s gentle on the stomach. I’ve taken it on an empty stomach without any issues, which is rare for a B-complex. The capsules are small and easy to swallow, and there’s no weird aftertaste or bright yellow “B-vitamin pee” (if you know, you know). The only downside is the price—it’s on the premium side, but with Thorne’s reputation for quality and clean ingredients, it’s worth it. Plus, with only one capsule a day, the bottle lasts longer than you’d think. If you’re looking for a high-quality B-complex that boosts energy, supports mood, and doesn’t mess with your stomach, this is it. 4.8/5
