Rejuvant Women's AKG Longevity Supplement 1000MG Ultra 98% Pure (Calcium Alpha-Ketoglutarate), Patented Vitamin Rich Controlled Release Formula Supports Cell Repair and Quality of Life, 60 Capsules

I’ve been on this for 5 years. It really works for me. Specially with skin.

I was interested in this supplement because we're all getting older. Also, supplements that aim to be science based intrigue me. That said, before I take anything I try to get a feeling for how safe a supplement might be by looking at the Transparency and accountability of the company/manufacturer/distributor as well as the apparent quality of the product.Transparency: There is a large amount of literature available on the internet about both Ca-AKG and about Rejuvant and about the studies they've done. The brand Rejuvant is owned by Ponce de Leon Health Inc. It is easy to find information about the company. According to the “Robb Report '' Rejuvant was developed in collaboration with Dr Brian Kennedy PhD at the Buck Institute for research on Aging in 2015. They have evidently done multiple animal studies and at least one human study. They claim multiple trademarks, but I only found trademark activity for this brand in India (that doesn't US trademarks don't exist, just that I couldn't find them for Rejuvant). They do have at least one US patent (and claim several more patents pending I believe).Accountability: Per Amazon, this product is said to have been formulated and produced in the US, in a GMP certified facility. I’ve also read that it's made in India. I can not verify the GMP certification or 3rd party lab testing, but given that there have been millions invested in this product, I suspect that they are motivated to put out a safe supplement.Quality: Each serving is two tablets, making these three bottles a 3 month supply. The tablets are relatively large and not meant to be chewed, as I believe the main feature of this formulation is that it’s time released. I didn't have trouble swallowing these, but took them with a generous amount of water. While they have researched these, common critiques that I saw in my brief review include the use of a particular epigenetic (aging) marker tool and also the lack of a control group. I believe they are planning to continue their research with the addition of control groups.I took off a star because of the high cost of this supplement (which may be worth it) and because while research is promising, it is a work in progress. As always, it's good advice to both speak with your health care provider and to educate yourself before using any supplement.

AN outstanding product! I have been taking it for 6 months - amazing results!!

Excellent product

I've been taking this product from Rejuvant for some weeks now, and I am quite mixed in my feelings about it. The good news is that the pills are just very easy to swallow; they're small, round, and this is the important part to me since I loathe huge horse pills.Effects-wise, I do feel like I get a little energy boost from these. It's not quite a shot of espresso or anything—you know, just enough to be noticeable. But the best part: it doesn't give me the jitters or crash later on, like what I've experienced with other supplements that gave me an energy boost. That is a big win right there.I also like that this product supports healthy aging. I am not getting any younger, and I'll try almost everything to stay healthy and active for as long as possible.Now, the not-so-great stuff - the price for this product is very expensive for a 30 day supply. I am really not sure it's worth the cost if I'm being completely honest here. I have taken this for weeks now, and other than that slight energy boost, I don't feel much else. The product information states that "Eight years average decrease in biological age in the first SEVEN months of taking Rejuvant". So to see results you'll need to take this for at least seven months, according to them. At almost $100 per bottle at the time of writing this after seven months of use, well, that's a lot of money to me.Don't get me wrong; I'm happy to spend money on my health, but I'd like to actually see something for it. Thus far, I am just not convinced this product is a good value for the money.

It took about a week, but I have much more energy! It didn’t hurt my stomach when I took them on an empty stomach, which I’m sensitive to.

From what I can tell, though, the men’s formula contains vitamin A but no vitamin D, and the women’s formula contains vitamin D but no vitamin A. I’m outside a lot, so I’m not concerned about my D levels, so I’ve probably got the best one for me.I’ve been taking these for almost three months, and it’s a three month supply. They’re fairly small round but flattish pills, and it’s easy to swallow two at once. I haven’t noticed any scent or taste. I quit quite a few of my other supplements while taking these, to try and see what they’d do for me all on their own. My energy level is as good as ever, my focus is very good, and I don’t struggle with brain fog until and unless I’m sleepy. I sleep well and wake up rejuvenated. Big question— would I buy these again? If I took a “your biological age is x” kind of test and it showed improvement— well of course I would, even if I had to take out a second mortgage. But without that, it’s hard to know. I wanted to try them because I thought anything this expensive just might work miracles. But honestly, I’m more likely to try to source the ingredients at a lesser cost. If you can afford it, it’s certainly worth a good long trial. As with all supplements— do your own research!

Girlfriend is very satisfied with the results thus far
