Fact of life, you get older and cognitive abilities along with memory aren't what they used to be. Fortunately there are some supplements that have shown promise to help correct the situation. Gingko Bilboa is one of the options where a lot of research suggests it can help in many ways. I started using it again a few months ago after a hiatus of about a year. When I stopped, it was because of a cost issue. For me, it was a case of looking for cost-effective things that help with cognitive function and other age-related issues. Then there's the added benefit that, as suggested, this is a very good anti-oxidant.Because I have already been using Ginkgo Biloba, there was no moment that is noteworthy once I started using this product, and there hasn't been anything negative that I can mention. In general, I tend to feel better a couple of hours after taking the first capsule. It does take a while for the body to digest and then get things into the blood stream. This is by no means to say that I feel the same every day, but I will state upon reflection that it's probably 80% or more of the time. How an individual will respond depends on many factors, and it pays to talk to a healthcare provider to ensure that there won't be any contraindications when said individual is using prescriptions.👀 Before starting any supplement that's not a "standard," such as Vitamins C and D, it's a good idea to talk with your healthcare provider. I always see our holistic practitioner and have him test whether or not I should be using anything new. Everyone's physiology and nutrition requirements can vary greatly.It does have a Heath Canada NPN number - 80091428, and the label states it's made in Canada so I'm not concerned about quality control.► Expiry date on my container is 08/27, so not only does this have a long shelf life, but it's unlikely that this has been sitting on a shelf somewhere for years.The downside to this product is the cost. As I write this review, it's marked at $32.80 for 90 tablets that contain 90 mg each. Here on Amazon, there are better-priced options. I've been using a product that has 60 mg per capsule but only costs $49.99 for 400 capsules; I've been taking one in the morning and then again in the evening as recommended by my healthcare provider. Obviously, this is a far better-priced product that is also Heath-Canada approved and made in Canada.Biogenique makes good supplements, but each one I have used is priced far above the competition without offering a significant value that makes up for the increased price.Based on the price, there is no way I can give this more than four stars and actually feel like it should be three, as there is no value that justifies the incredibly higher price than competing products.
