Our benefits

Daily green supplements are soaring in popularity because they help fill nutritional gaps in your diet, reduce the risk of sluggish workouts, and fuel a vast improvement in the length and quality of your workouts. Many competing green food supplements list high levels of trendy additives but fail to deliver meaningful doses. ON3 Athletic from Sun Chlorella takes a different approach.

Our unique formula delivers optimal doses of over 60 functional nutrients, including vitamins, minerals, superfoods, and more, all specially crafted for maximum absorption in your body.*

  • Supports Greater Endurance and Stamina Whenever You Work Out*

    You’ll get a energy boost — without any caffeine jitters — so you can enjoy longer, more intense workouts. It’s all thanks to the adaptogen herb Eleuthero, as well as premium MCT for clean fuel and the best chlorella supplement to elevate oxygen flow.

  • Helps Optimize Muscle Repair, Recovery and Growth*

    The Pure Plant Protein in ON3 Athletic provides the essential amino acids your body needs to recover fast. In addition, the powerful antioxidant Astaxanthin helps combat oxidative stress, while Almond Mushroom (Agaricus Mushroom) supports immune function and recovery.* Clinical data in healthy adults show these combined ingredients may lessen muscle soreness after intensive sessions and support weight loss goals by preserving lean mass.

  • Nourishes a Healthy Gut and Aids Digestion*

    The Chlorella in ON3 Athletic, coupled with the natural enzyme Grain Koji, goes to work fast to support the growth of beneficial gut bacteria to relieve discomfort and get your digestive system back on track. You'll have better nutrient absorption to maximize results.* Together, these probiotic supplements help balance microflora, ease occasional bloating, and optimize nutrient uptake for overall health.

  • Enhances Focus and Mental Clarity*

    The synergistic combination of Astaxanthin, Eleuthero and Chlorella Growth Factor reduce oxidative stress in the brain and provide the nutrients it needs for optimum focus and clarity.*

  • Supercharge Your Immune System*

    You get healthy portions of high-quality Chlorella — the superstar of super foods — along with Almond Mushroom (Agaricus Mushroom) for powerful antioxidant protection, along with support for reduced inflammation and improved immune health.* Regular use helps maintain normal blood pressure and delivers long-term health benefits backed by decades of research.

  • I just started taking ON3 Athletic after struggling to find morning greens that didn't taste bad. It's very smooth to drink.... kind of like an iced matcha! It has just enough sweetness to make it easy to go down. My husband even stole some for himself and is loving it! Happy to be getting in extra protein and supplements with one beverage.

  • ON3 Athletic is a game-changer! After comparing it side by side with one of those trendy greens powders, I found ON3 Athletic tastes better, has a more advanced ingredient profile, and includes pea protein for a plant-based protein boost, which I love. I’ve been using it daily and feel fantastic!
