High quality and smooth
Flavor Name: Unflavored, Size: 90 Servings (Pack of 1)
This mixes really easily and is completely tasteless, which makes it easy to add to drinks. I personally use creatine more for the cognitive benefits than the muscle benefits, and I’ve noticed a positive difference since using it.
I wanted a high-quality option and this one definitely feels like it. One thing I like is that it dissolves well and doesn’t have any gritty texture or weird aftertaste. I usually add it to my coffee and it blends in perfectly. I will even add it to smoothies or sometimes just in cold water and drink it. You can’t taste it. I’ve learned to combat the bloat by staying hydrated and drinking a lot of water. For me, drinking it with coffee was fine. But when I had it with tea, since that is a stronger diuretic for me, my stomach did feel bloated and uncomfortable. But I’ll definitely continue using it.

Would put on Autoship
Flavor Name: Unflavored, Size: 30 Servings (Pack of 1)
I like that these are individual packs that I can take on the go. It mixes well in my shakes and doesn’t affect the taste. I feel the price is great for a good quality product.

Finer consistency than others, won't fully dissolve. Overall content.
Flavor Name: Unflavored, Size: 30 Servings (Pack of 1), Flavor Name: Unflavored, Size: 30 Servings (Pack of 1)
I have purchased Thorne’s Creatine before and continue to find it to be a high-quality supplement. The most immediate observation compared to other brands is the texture; the powder is ground a bit finer than standard creatine monohydrate. While this doesn't necessarily change the efficacy, it makes the powder less bulky and the single packets much easier to pack into smaller containers for transport. Also, despite the finer consistency, don't expect the creatine to dissolve fully.
This version, individually packaged 5g servings, is particularly helpful for my frequent work travel, as it is easier to manage on the go. It remains unflavored and mixes as expected with grit. Since it is NSF Certified for Sport, I have extra peace of mind regarding the purity and label accuracy. Overall, it is a reliable, professional-grade option that is well-suited for someone who needs a portable and consistent supplement.

A great supplement for daily use
Flavor Name: Unflavored, Size: 90 Servings (Pack of 1)
I put two scoops in my coffee daily and can feel the benefits related to muscle recovery and brain fog - the two main reasons that I take this supplement in the first place. I mix it with collagen (also flavorless) and can sometimes taste a hint of the two supplements, but not enough to keep me from enjoying. Highly effective when taken regularly.

I only wish I had tried this sooner!
Flavor Name: Unflavored, Size: 90 Servings (Pack of 1)
I don't write many reviews, especially for supplements, which are often overhyped by influencers, and results can seem so subjective. I decided to try creatine after following Dr. Louisa Nicola, who advocates it for physical and cognitive health.
Late 50s, post-menopause, diagnosed with pre-osteoporosis, have always been pretty active and a healthy weight, but started to get serious about strength training about 15 months ago. Some moderate improvements in what I could lift, but not as much as I'd hoped. I was getting discouraged.
Six weeks ago, I started this creatine (1 scoop daily), and the past few weeks, it's like a switch has flipped. I've been able to increase my weights, my strength is suddenly improving (especially in my core/back, which in turn improves my balance and flexibility), and I'm seeing the tiniest bit of definition starting to show in my shoulders, back, and abs. For an ectomorph body type (long, lean, low muscle mass, hard gainer), it's been amazing.
The only thing I've changed in my diet and activity is adding this supplement. I wish I had tried this a year ago when I first bought it then shoved it to the back of my cupboard. At that time, I was a little freaked out when I read that it can cause water retention. I haven't had that at all, and I haven't had any digestive issues. Mixed with plenty of water, it's tasteless and easy to fit into my day.
I'm also intrigued by the cognitive protection it can potentially provide (again, as stated by Dr. Nicoloa). Alzheimer's runs in my family, and I'm doing everything I can to hopefully prevent it.
