I have been taking these vitamins for 2 years with a one-month break. If taken for 3 months, they keep the body functioning at a good level. The only negative aspect is the strong smell

First of all, I would like to respond to Konstantinos_Sarlis5774 and say that all the vitamins that contain the B supplement have a similar size and smell, even if you take pure vitamin with a B complex, it will still be the same, let alone a multivitamin that contains a bunch of different vitamins. It doesn't matter if it's Solgar or Life Extension. If you take a "multivitamin" that doesn't have a corresponding smell and size, then it's fake, also this specific one is not a pill but a capsule, there's a difference.

Secondly, this specific one is amazing, I took it for 2 months and I actually felt the difference in energy/endurance almost immediately, even in my sleep, I sleep more easily. I did blood tests and they came out great, I had an issue with B12 for example, it was around 200~220 for a while. Within 2 months, it went up to 680. With other vitamins, I tried for months and it would only increase with difficulty, gradually.

Then I looked into why. For example, the well-known Solgar with VM2000 has a... fake formula. What it does regarding vitamin D, it gives us D2 (ergocalciferol) which is the inferior version of vitamin D with 1/10 of the absorbability compared to D3! (cholecalciferol)

Not only that, Solgar gives 400IU D2 (like 40IU D3) while Life Extension gives 2,000IU D3! We're talking about night and day, a tremendous scam. For those who don't know, 40IU (International Units) is 1mcg, which means one microgram, which is 1/1000 of a gram! What can that do for you?

The same goes for B12, Solgar gives 100mg of cyanocobalamin while Life Extension gives 300mg of methylcobalamin, look it up to see which one has better absorbability... night and day.

After Solgar puts some fake stuff in, it then adds 5mg of Taurine so that you feel a little energy and say that it did the job, while taurine is temporary. But do you take multivitamins or Red Bull?

I believe that the One per day (or even the Two per day, it's practically the same, just half the dosage for those who can't swallow) is a very good multivitamin if not the best, as I have tried several but none did the same job.

I cannot yet judge the effectiveness, however it should be mentioned that visually, in terms of taste/smell, unfortunately, and in size, it appears identical to Solgar VM2000.

The rating is solely based on the fact that the pill is huge. Basically, almost 2.5cm in length and 0.8cm in height, with a terrible taste/smell (similar to the VM2000 as mentioned before).

Personally, I struggle several times with the use, even though I have no issue with any other pill I have tried. If someone generally does not handle well in this aspect, it is better to avoid them simply because they will not be able to swallow them and the money will go to waste.

From the first days, I saw a difference in my endurance because I have a quite tiring job. I highly recommend the product.
