I keep ordering products from Natural Factors because I like the brand and find the products I have tried so far have been good quality and effective. Like every other product by this brand this one has an NPN, and is ISURA certified clean. This time I ordered their Regnerlife Acetyl-L-Carnitine. I received the 500 mg, 120 vegetarian capsules. The recommended dose is 2 capsules 2 times a day with meals, or as directed by a healthcare practitioner. By taking the recommended dose this bottle will last me about a month. The expiry on the bottle I got is just over 3 years from date of delivery. I find the product effective and can be a bit stimulating which is why I take my 2 doses with my first 2 meals of the day. I find it easiest to take the capsules with a glass of water. The capsules are similar in size to other supplements capsules. They don't have a smell and I didn't pick up any taste or aftertaste. I have been taking the recommended dose as directed and have not had any adverse reactions. 5/5

    Acetyl-L-Carnitine is a decent supplement with quality ingredients, odouless and tasteless. It’s easy to incorporate into my daily routine, but after using it for a while, I didn’t notice much of a cognitive boost. There may be a slight energy lift, but for me, other supplements like Omega-3, Lion’s Mane, or Alpha GPC have a more noticeable impact on focus and mental clarity.

    I typically prefer L-Carnitine Tartrate for its benefits in androgen receptor sensitivity and fat metabolism, so Acetyl-L-Carnitine felt less effective in comparison. The dosage of 4 capsules a day adds up to about $0.76 daily, which is a fair price, but for my goals, it’s not a must-have.

    Overall, this is a good product, and it might work better for others, but I’ll be sticking to other options for cognitive support and energy. It's not bad , it's just not essential for me

    Not sure why but mine came expired by 2 years. I am not sure whether it's safe to take and just the potency is reduced but it's disappointing.

    L-Carnitine is an amino acid found in a variety of foods. Acetyl L-Carnitine (aka ALCAR) has been used for years as a dietary supplement with the potential of offering myriad benefits. I have used it on and off. I can't say the benefits are radical but YMMV. As a food, it should be well tolerated. Nonetheless, I suggest doing your own research using trusted sources.

    While it may pay to compare, this is a good product, worth shortlisting. Recommended accordingly.

    I take this vitamin/amino acid supplement to boost fertility in the lead-up to IVF. I cannot speak on the actual contents of the capsule of course. I have heard that Natural Factors brand is a good, reputable Canadian brand. These capsules are easy to take as they are flavourless and the size isn't difficult to swallow. Note that your body can only absorb so much at a time, which is why it is suggested on the bottle to take some at different times of the day.
