   This is a super formula that athletes take. While I’m not an athlete these days, I want whats best. This formula contains many Vitamin B supps including B12. So much vitamin B that you probably won’t assimilate everything thus the entertainment part which is to discover your urine has turned neon yellow LOL.

   THORNE B-Complex #12 is a game-changer for energy and mental clarity! I’ve been taking it for a few weeks, and I’ve noticed a big difference in my daily energy levels and focus. Unlike other B-vitamins I’ve tried, this one doesn’t upset my stomach, which is a huge plus. The capsules are easy to swallow, and I appreciate that THORNE uses high-quality, bioavailable ingredients so my body can actually absorb the vitamins. I also feel less fatigued in the afternoon. I love that they are tested by a third party lab too.

   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!

   The Honest Dose

   junho 9, 2025

   I’ve been taking THORNE Vitamin B12 for 5 months now, and I can confidently say it’s one of the best B12 supplements I’ve tried! Here’s my honest breakdown:

   🔹 What I Love:
   ✔️ Highly absorbable formula, THORNE uses methylcobalamin, the active form of B12, making it easier for the body to absorb.
   ✔️ Energy & mental clarity, Since taking this daily, I’ve noticed a huge improvement in my energy levels, and I no longer feel sluggish throughout the day. It has also helped with my mental focus and concentration.
   ✔️ Supports recovery & mood, This has been a game changer for me in recovering from sleep deprivation and anxiety. I feel more balanced and less fatigued.
   ✔️ Clean, high-quality ingredients, No unnecessary fillers, additives, or artificial ingredients. THORNE is a trusted brand that prioritizes purity.
   ✔️ No weird aftertaste, Some B12 supplements have a strong taste, but this one is neutral and easy to take.

   🔹 What Could Be Better:
   ❌ Small bottle, I wish it came in a larger size, especially since I take 2 daily!
   ❌ Not the cheapest option, It’s a premium supplement, but given the quality, I think it’s worth it.

   🔹 My Personal Experience:
   I originally started taking B12 to help with energy, nervous system support, and recovery from stress, and this supplement has exceeded my expectations. I feel more alert, less anxious, and overall healthier since incorporating it into my routine. It’s now a staple in my daily supplements!

   🔹 Final Verdict: 10/10 ⭐️
   Would I recommend it? Absolutely! If you need a high-quality, effective B12 supplement for energy, brain function, and nervous system support, this is one of the best options out there.

   After having my labs drawn, it came back that I am extremely low in Vitamin D and Bs. My doctor recommended these two vitamins and after just 2 consistent days I already feel 10x more energized! The size is easy to swallow and little to no after taste. Highly recommend! I did notice my urine being very bright yellow.

   Especially good because it has small amounts of b5 and biotin.

   Took a couple of extra weeks to arrive from the others ordered on the same day, however, the product itself is good

    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
