- Reviewed in Canada on November 30, 2023Verified PurchaseI recently started incorporating Jamieson Vitamin B12 (Cobalamin) 1200mcg Timed Release into my daily supplement routine, and the positive effects have been truly remarkable. With 80 tablets in each bottle, this product has become an essential part of my overall wellness regimen.
The timed-release feature is a game-changer for me. It ensures a gradual and sustained release of Vitamin B12 throughout the day, providing a consistent boost of energy and mental clarity. I've noticed a significant improvement in my overall vitality since adding this supplement to my routine.
Jamieson's commitment to quality is evident in this product. The 1200mcg potency is substantial, meeting and exceeding my daily B12 requirements. The tablets are easy to swallow, and I appreciate that they are free from common allergens, catering to various dietary preferences and sensitivities.
Vitamin B12 is crucial for energy metabolism, and I've experienced a noticeable increase in my energy levels since incorporating this supplement. It has become my go-to solution for combating fatigue and supporting my overall physical and mental well-being.
The 80-tablet format provides excellent value for money. It's a cost-effective option, ensuring a sufficient supply for a prolonged period. The packaging is practical, making it easy to incorporate into my daily routine without any inconvenience.
In conclusion, Jamieson Vitamin B12 1200mcg Timed Release has exceeded my expectations in terms of effectiveness and convenience. Its timed-release feature, high potency, and overall positive impact on my energy levels make it an essential component of my daily supplement regimen. I highly recommend it to anyone seeking a reliable and high-quality Vitamin B12 supplement for enhanced vitality and well-being.

- Reviewed in Canada on May 17, 2025Verified PurchaseGreat Canadian product..
Exactly what I needed
- Reviewed in Canada on January 30, 2025Verified PurchaseI’ve been taking the Jamieson B12 Timed Release tablets for a few weeks, and they’ve been okay overall. The timed release formula ensures a steady, gradual boost of energy throughout the day, which I appreciate. I also noticed a slight improvement in my focus and general well-being, which I think is partly due to the faster absorption from the methylcobalamin. The fact that it’s one tablet a day is convenient, and I like that it helps support things like the immune system and red blood cell production. However, I did feel a bit of an initial energy spike right after taking it, which was a bit unexpected for a timed release. For vegetarians or anyone who may be lacking B12, it’s a solid option, but it’s not a miracle worker. It’s effective but not as life-changing as some might expect.
- Reviewed in Canada on May 17, 2025Verified PurchaseThese pills are very tiny, but a big dose. So easy to take.

I went from below 200 to over 500 for B12 for my bloodwork, I notice a huge difference on how I’ve been feeling, it does work don’t hesitate get it if your low B12, these are better then quick desolve ones! 5+ stars!

5.0 out of 5 stars Gives more energy!
Verified PurchaseI do notice that I have more energy since taking these. After watching different videos, it is not recommended to swallow the pill whole, but to chew or let dissolve in your mouth. It is not a bad taste, but it will get stuck to your teeth. I let it dissolve by keeping it in my mouth and slowly biting on it. The coating last a long time so you have to aide the dissolving process. I've already ordered more, and hopefully I'll get the same formula.
