Buying Guide: How to Choose the Best ASU Supplement
Ingredient Quality and Dosage
The most important factor is the amount of ASU per serving. Most clinical studies use 300 mg of standardized avocado soybean unsaponifiables. Look for products that clearly state the dosage and source of ingredients. Brands like Arthrocen and AvaSun offer 300 mg capsules that align with research-backed amounts.
Also consider whether the ASU is derived from non-GMO sources and if the product is manufactured in FDA-inspected facilities. This ensures purity and consistency. For athletes who need robust joint support, our best joint support for athletes article covers additional criteria.
Additional Joint-Supporting Ingredients
Some ASU supplements combine the compound with other proven ingredients like glucosamine, chondroitin, or Boswellia serrata. For example, Nutramax Cosamin ASU includes 1500 mg glucosamine HCl and 350 mg chondroitin sulfate alongside ASU. This multi-ingredient approach may offer faster relief for some users, but it is not suitable for those avoiding shellfish or seeking a purely plant-based option.
If you prefer a streamlined formula, single-compound ASU products like N’More or NOULIQ are excellent choices. They focus solely on the plant compound without extra additives. For budget-conscious shoppers, see our Best Joint Support on a Budget recommendations.
Vegan and Clean-Label Options
If you follow a vegan diet or avoid animal products, look for ASU supplements that use plant-based capsules and are free from gluten, dairy, and shellfish. Arthrocen and NOULIQ offer vegan-friendly formulas. These products are also non-GMO and free from artificial colors and flavors, making them a clean choice for daily use.
For busy men who want a simple routine, these once-daily capsules integrate easily into your morning regimen. Explore our best joint support for busy men guide for more tips.
