Here is the full list of active ingredients in Super Joint Support, listed in order of appearance on the Supplements Facts sheet provided by the manufacturer.
Vitamin D (23.8mcg) - Being deficient in vitamin D can cause all sorts of health issues and it can worsen joint pain. The dose in Super Joint Support is over the recommended daily intake (RDI), so unless you require an especially high dose you probably won’t need to take stand-alone vitamin D supplements as well.
Vitamin B12 (250mcg) - At 10,417% of the RDI, this dose of vitamin B12 seems ridiculously high. B vitamins, including B12, are thought to improve joint mobility but there is no evidence we are aware of that would advise taking a dose this high. If you are deficient in vitamin B12 then perhaps this dose would be warranted, but ordinarily a dose of around 1000mcg is recommended to resolve deficiencies.
Magnesium (400mg) - Magnesium could improve joint cartilage and has been suggested as a potential preventer of knee osteoarthritis. However, evidence is lacking to support these claims at present.
Sodium (10mg) - Sodium is the basic compound of salt, which is in no way associated with joint support, improvement, or illness prevention.
Potassium (125mg) - Potassium deficiency is known to cause muscle cramps as potassium is involved in muscle contractions, communication, and overall function. Ensuring you are not deficient in potassium will keep your muscles operating smoothly and this will reduce the stress and strain on joints. However, 125mg of potassium is quite a small amount and most people will get far more potassium from eating a normal diet.
Glucosamine (1000mg) - Glucosamine is a compound found in cartilage—the tissue surrounding all your joints. It can also be derived from shellfish or made in a laboratory. There is more than one type of glucosamine, including glucosamine sulfate, glucosamine hydrochloride, and n-acetyl glucosamine. Each type is thought to have slightly different properties. The type included in Super Joint Support is glucosamine sulfate. This type has been linked to joint support though it is thought to work best when taken together with chondroitin.
Marine Magnesium (1000mg) - This is a proprietary blend of minerals. It could be useful but we don’t really know since we don’t know exactly what is in it or the doses. Here at Centre TRT, we’re not fans of proprietary blends. We want to know exactly what is in our supplements. Since they told us everything else that’s in their joint supplement, we feel it was unnecessary for Super Joint Support to include a proprietary blend, even if it is for only a small portion of the overall ingredients.
Collagen Type II (500mg) - An anti-inflammatory, collagen is found naturally in joints and studies show that orally consuming collagen can support healthy joints and alleviate symptoms of joint pain. This is a decent ingredient for a joint supplement.
MSM (250mg) - Methylsulfonylmethane, known commonly as MSM, is thought to reduce symptoms of knee osteoarthritis (OA). More evidence is needed to confirm the early findings, but so far MSM seems to have great potential as a joint supplement.
Alpha Lipoic Acid (150mg) - We’re not sure why this is included. While it does have anti-inflammatory properties, there is no evidence that it works on joints. Simply because something is anti-inflammatory does not, unfortunately, mean it will work on all kinds of inflammation in the body. If only it were so simple. There are no studies linking alpha lipoic acid to the alleviation of joint-related pains and illnesses.
White Willow Bark Extract (125mg) - This is basically aspirin. It will reduce pain, because that’s what painkillers do, but it won’t benefit your joints nor remedy underlining issues. This could also be a risk for anyone on blood thinners.
Vitamin K2 (45mcg) - Vitamin K2 can prevent OA, according to several studies. It’s unusual to find this in a joint supplement. The only other occasion we know of is FlexAgain, which is probably the best joint supplement currently available.
