Instaflex is our second pick because it's a well-known brand that makes a quality product. However, they fell into the second spot for a few reasons.
First, although Instaflex has ingredients that could be effective, some included ingredients do not have strong scientific backing. This is perplexing because the suggested dose of Instaflex is three capsules per dose. This product contains turmeric, which is a good thing. However, it may not be absorbed as well by the body without black pepper extract. It also does not contain collagen, which is a key ingredient in our top-rated product on the list. Finally, this product ranks second because it includes glucosamine, which has not been proven to support joint health. Instaflex is the perfect example of more not always being better. Our bodies need proper doses of high-quality, scientifically studied ingredients, not the "everything but the kitchen sink" approach.
Instaflex entices customers with a low up-front cost, but automatically enrolls them in an auto-ship program. If you're not careful, you'll be signed up for a subscription that automatically renews at $69.95 plus shipping and handling every month. Moreover, the return policy is only 30 days. The manufacturer will not accept a return of any shipment that is more than 30 days old. How are you supposed to know if it works with such a restrictive return policy?
If some of these issues were improved, we may consider giving this product a stronger recommendation.
