Review: Can I give 6⭐️?! - Definitely on a health optimization journey. Postmenopausal. May my energy rest in peace. Have been taking quality methylated multi vitamin that included B6 for quite a while. Still had persistent lack of energy/fatigue. Bought this, and OMG! Life changing! I happen to have the MTHFR gene mutation (fascinating rabbit hole) and this type of B12 is amazing. Good steady energy, not at all like caffeine. Focus improvement, and just a sense of hey there’s hope it’s OK. Take one or two times a day. Amazing. Functional medicine doctor even supported the science behind it. Super light pleasant easy taste (not that that matters-could taste like old shoes & it would still be worth it.

Great product

### ⭐⭐⭐⭐⭐ Game changer if you get lethargic and head aches from most b12
*by M***S on February 19, 2023*

I don’t usually write reviews but it really helped me to read others’ experiences. There isn’t much information online about adverse reactions or processing from methylcobalamin or cobalamin b12 supplements, which are most of the b12 supplements out there. My experience consisted of having low b12 and needing to supplement but all the supplements would cause lethargy starting about 2-3 hours after I took the supplement which would lead to shoulder/neck then head tension or a migraine. Higher doses would increase the effect and I had nausea a few times. And these would be from very high quality supplements. I even tried food based lower dose (250% DV) ones and still it had that effect to some, maybe a lesser degree. Dessicated liver seems fine but doesn’t raise the levels enough. It has felt like 5 years of a catch 22 of low b12 and feeling low energy so taking a supplement which makes me feel worse, but still needing b12. So anyways, I don’t know if I have a gene mutation or not. I haven’t been taking this form of b12 for very long but the difference was noticeable on day 1. Each serving size has around 41,000% of b12 and the bottle says to take 1-3 servings a day (1mL or one dropperful). I measured that each dropperful has around 20 drops, so if I take 5 drops I’m getting around 10,000%. Literally that’s all I have needed 1x a day, it’s pretty crazy. I stopped drinking coffee over a year ago but this supplement feels comparable to drinking coffee. Lots of energy and productivity and more of a clear head. I think if I took a whole serving size it would be too much energy!! I’m just so happy to feel like I have made a breakthrough with energy and b12.
