BioTropicLabs Oxcia – Clean, Powerful Energy Delivered via Blood Oxygenation-vasodilation. Apex Design gets More vasodilated and oxygenated Blood to Where You Need it Most, and Faster!

I’ve been using this product for about a year. I first learned about it on the Ben Greenfield Podcast and decided to give it a shot. This product is truly amazing and the ingredients have been shown to work in a number of studies. I make sure to take this before all of my longer training days and it hasn’t let me down.

BioTropic makes a great product. I’ve been taking AFA (morning), Chlorella (afternoon) and Oxcia (pre-workout) 5-6 days a week for about 2 months now. I have seen a significant improvement in my running endurance and I feel more explosive even in short intervals. I typically run 3-5 miles a few times per week, with one run being hill repeats.I cycle all supplements in my toolkit, but I will definitely plan to load BioTropic before any competitive events.

I've been getting good results from this product; it digests well without any discomfort or negative side-effects... it gives me a boost during my workouts for sure.

I’ve used AFA extensively in the past and decided to focus on Oxcia for the nitric oxide boost. While I only been supplementing with Oxcia for three weeks including one 24 hour race, I could certainly feel the effects, which for me I equate to less perceived effort. A bit early to call it a mainstay in the sea of supplements I use, I will continue to use at least long enough to validate the effects. The supplement itself caused no stomach distress, which I do get with other nitric boosting powders. The cost appears reasonable, but as an ultrarunner I’m taking a bit more, which makes the cost per run increase.

On my third month of using Oxicia and this product has completely exceeded my expectations for NO2 boosting.Added the chlorella product two weeks ago and the results have been even better. Also noticing a very strong immune support benefit, despite a lack of sleep and a ton of stress.

Love this product (Oxcia) for increased energy and immunity. The ingredients are perfect for an endurance exerciser like me, who turns over red blood cells quickly. I also ordered two bottles each of their AFA and Chlorella products but I’m taking them separately for the first bottle of each so I can tell the differences between the products. I’ll try to leave another review after I’ve taken the other two products.

I used the Biotropic stack of AFA, Chlorella, and oxia leading up to my last 50k. Due to an eye surgery I went into the race in little training and my longest run being 10 miles in the 5 months leading up to the race. I believe this stack is what got me through the race with a top 10 finish and PR. Won’t train for another endurance race with out them!

Capsule big improvement over previous tablets. Good way to get your L-citruline
