Common questions we came across whilst researching our Instaflex review
Instaflex gets the ingredients right, for the most part, it just under doses a couple of ingredients.
Turmeric Extract - A mainstay in every good joint supplement as it's been proven time and time again as shown in multiple meta analysis of double blind trials [2]. The problem is that most of the studies show higher doses are more effective with 500-1000mg being recommended. And unfortunately instaflex only contains 200mg.
Resveratrol - This is dosed at 100mg which is right, we've already mentioned that resveratrol works quite effectively in supporting joint health, but also helps support other areas of healthy ageing, having benefits to cognitive function as well.
Boswellia Serrata - It's a a little early to say how effective this ingredient is, there have been some positive studies in relation to knee pain, [3] but we can't fully recommend it's use in a joint health supplement just yet as these weren't placebo controlled.
Type 2 collagen - has been shown to be effective at reducing arthritis pain and improving joint function [4], there aren't a huge amount of human studies, but there are enough to suggest the ingredient is pretty effective. The problem is, that collagen supplementation needs to be above 1000mg to have it's maximum efficacy, and instaflex only contains 100mg.
Hyaluronic acid - Injections of hyaluronic acid work, oral supplementation however appears to be ineffective for relieving joint pain.
Black Pepper Extract - this is in a lot of supplements, it won't do anything to reduce joint pain, but that's not why it's included, black pepper extract helps you absorb vitamins and miners more effectively.
