Isotonix is a range of supplements in powdered form that will work with ‘how your body is built to take vitamins’. Isotonix supplements are manufactured Market America – a US-based multi-level marketing company established in 1992.

We take an in-depth look at Isotonix and Market America to find more about this supplement range and the company behind it.



Isotonix is a range of powdered vitamins and nutrients suitable for all types of purpose but mainly focused on general health rather than weight loss. Unlike many other supplements on the market, all Isotonix supplements are in powder form to which you just add water and drink in a shot-sized glass. In addition, they contain added ingredients to replicate body fluids pressure.

Isotonic products are nothing new. In most cases, isotonic drinks are marketed as sports drinks because they contain glucose and electrolytes that need replacing after being lost through sweat during exercise.

Isotonix products are not the same: the supplements are not quick fix sports drinks and, according to the product information, are the world’s most advanced nutraceuticals.

As the product information explains,

Isotonix products are scientifically formulated with the perfect balance of fructose, d-glucose, citric acid, potassium bicarbonate and other ingredients to ensure that they are isotonic the moment they enter your body.

There is very little information about these ingredients. They do not show up on the ingredients list so we only have the advertising’s word promising a ‘perfect balance’.

The product information continues,

“Isotonic” means having the same fluid pressure as your other bodily fluids like blood and tears. When you eat food, drink a beverage, or take a pill or capsule, your stomach must first secrete diluting juices, enzymes, hydrochloric acid, and at least one vitamin-binding protein to continue the process of digestion.

It continues explaining the time-consuming drawbacks of regular supplements,

Muscular contractions of your stomach then mix the contents until a reasonably uniform solution is achieved. This process can take anywhere from 40 minutes to four hours.

This sounds good, of course, and we like the idea of an instant vitamin kick and nutrients that are instantly absorbed by the body but is this actually important to long-term health? Does it really matter if your supplement takes between 40 minutes and 4 hours to work? Does your long-term health need to be hurried this way? After all, conventional medicine does not usually bother with delivering prescription medication isotonically so is it really necessary for vitamin supplements? We will look into this question later.


The Isotonix advertising is extremely glossy and the overriding impression is that the wide range of vitamins is of extremely good quality. One of the most popular is the general health supplement, OPC3 – a blend of antioxidant-rich ingredients said to promote cardiovascular health and help maintain healthy cholesterol and blood sugar levels.

According to the product information, this contains key ingredients such as Pine Bark extract, a potent natural scavenger of free radical cells – the cells that cause diseases in the body such as cancer. Again this sounds great but there is no real evidence that it is true.

As well as OPC3, there are specific ingredient supplements such as Bromelain Plus – based on the enzymes found in pineapples and believed to have a healthful effect. There are mineral supplements such as Isotonix Multi Mineral and Isotonix Magnesium.

You can also buy bundles of products such as the Isotonix Daily Essentials Kit. This comprises of four supplements: a multivitamin with iron, OPC3, Vitamin B Complex and Calcium.

There seem to be Isotonix versions of most vitamins that you can buy in any health food shop.


According to many industry watchers, Market America – the company behind Isotonix – is a multi-level marketing company.

This is where a company’s products are sold via a network of ‘ordinary people’ working as distributors rather than sold through shops and stores. We have covered countless MLM companies in previous investigations including Plexus Worldwide ( and It Works! (

There are literally hundreds of MLM companies out there and many are operating in the health and weight-loss sector. Since the economic crash in 2008, MLM businesses have boomed in the USA as consumers look to add an additional income stream to their household earnings.

Isotonix looks a little different to most other MLMs on the market. It does not tout the business plan or promise any of the usual claims such as a new car or free holidays. Instead, you are invited to contact Market America via a form on the official Isotonix website titled Own your own Isotonix site. There is no information about the compensation plan on the product website.


Ex-Amway leader JR Ridinger founded Market America in 1992. The company does not produce its own products but instead has exclusive brands that only them sell. As well as Isotonix, there are some branded products we have previously covered including TLS Tonalin (

As a distributor, you can find products in a wide range of categories including pet care, anti-ageing supplements and financial services; there are lots to choose from.

Like with all MLM schemes, you are encouraged to build your down line and join other people as distributors. According to industry sources, it costs around $200–$300 a month as a monthly minimum purchase order to stay active in the business.

Opinion is mixed about Market America. It is a legit business and not a pyramid scam. However, many people will probably struggle in making a success of a distributorship if they lack sales experience. Other people are very happy at being part of this company and it is important to remember that it has been in operation for over 20 years so is obviously doing something right.


The Isotonix advertising is suitably scientific and glossy and it is very easy to get carried away with wanting these great health supplements that are delivered to the body instantly. However, the supplements are very expensive and will be beyond the budget of many people.

Isotonix supplements are sold via the official Isontonix website or via – the online market place for Market America supplements. The supplements are not cheap. One bottle of OPC3 contains 90 servings and costs a whopping $71.95. The Daily Essentials Kit containing four supplements costs $150.00 for a month’s supply and a basic multivitamin with iron costs $55.95. is available to worldwide customers including buyers from the UK. The daily Essentials Kit is £53.50 and Isotonix OPC3 for all the family, including children is around £60.

It is important to remember that you can buy vitamin supplements from other sources for much cheaper.

For example, an Isotonix vitamin C supplement costs £15.00 or $34.95 from either of the official Market America shopping platforms. Yet, you can buy an ordinary vitamin C supplement from an outlet such as Boots in the UK for around £2.50. In the USA, a good quality vitamin C may only cost you around $8.00 from Walmart.


No, not really. Isotonic vitamins and supplements are more expensive and according to expert opinion there is little point to taking them. They do not always work effectively and in many cases are wastes of time.

For example, vitamin C, calcium, iron, folic acid and several B vitamins are transported into the body via the small intestine, which can easily become overwhelmed by nutrients causing many to be eliminated naturally. According to medical experts, it is better to simply take a supplement in the usual way as a capsule because the body will eventually absorb the nutrients even if it does take a little longer.

Of course it all depends on the type of nutrient in the supplement. However, in the case of Isotonix, ALL the supplements are delivered in the same way regardless of whether they are suitable for this type of delivery or not. The truth is that for many supplements it would actually be better to just take an ordinary capsule:


There are hundreds of positive reviews for Isotonix supplements on Amazon alone. Isotonix OPC3 is one of the most popular so we decided to see what people had said about it.

Strangely, for a product with 419 positive reviews, only 10 people had actually purchased this supplement and were verified by Amazon as buyers. However, leaving that aside, many reviewers were extremely positive believing that the supplement was doing them good and protecting their future health.

After having numerous epidural injections at the cost of $1200. I was told by a friend to try this and omg in 4 days the pain in my back was 90% gone. He told me about this a year ago, I thought hogwash. As a last attempt I tried it like I said pain-free so far!!!

This was recommended by an acupuncturist as an immune builder. I started taking it several months ago and now have what seems to be boundless energy. I also take thyroid medication and even with that was on the low side of normal. After taking this for the period, had another test only to find I was exactly in the middle of normal.

Not everyone is as convinced:

My boyfriend and I both were taking this for about two months and didn’t see or feel any difference. I got one of the worst colds I had while taking it and there was no improvement in joint/muscle pain. It could be in my head but I think I felt better once I stopped taking it…

Don’t feel any different. I’ll finish the bottle since it’s quite expensive, but likely will not continue with it.

The problem with any product sold by multi-level marketing such as Isotonix is that the distributors can become fixated with the supposed benefits of the products. There is no reason why OCP3 really will work as well as described by customers. In addition, very few people appear to have bought it yet have been quick to add their comments.
We are not convinced.


The initial impression of Isotonix was quite good. We liked the scientific explanations and the glossy appearance of the official website but when we looked into the products further, it all went downhill. It seems that there is no real reason to ingest vitamins this way and for some nutrients, this mode of delivery simply does not work. The overenthusiastic customer feedback was unconvincing too. OCP3 is not going to cure disease and although you may find you feel better, it could be a placebo effect. A placebo effect should not be underestimated because the power of the mind is important but, in our opinion, it would be better for your pocket if you transferred all that belief to something less expensive than this supplement.

The Isotonix range does not impress us. It probably will not do you any harm but the supplements are overpriced as well as likely ineffective. In our opinion, this range looks like a gimmick. We are not impressed.

  1. Tried the Isotonix range of vitamins and OPC3 supplements a few months ago, for the first couple of weeks, I felt more energised, as claimed. However, the OPC-3 is quite over hyped. I was told to overdose 9 times a day! Yes, that’s right. a 90-day bottle will be consumed in about 2 weeks! That is about Aud$200 a month to be effective! This is some serious money!

    After a month’s usage, I took a 2 month break from these supplements.
    Decided to start using the supplements one day, and I felt absolutely no different!

    Does it work? Not on me. But it is definitely VERY expensive

  2. I feel your information is well targeted. I have specific requirements in a few vitamines. Isotonix was a recommendation. I went to investigate where and who made the product ant what was truly in it. Educated. I agree with your supplement absorption. There are actually more questions that should be answered before spending this kind of money. From Where are these ingredients durived,potency, life of, purity and on. Gimmicks are apenty marketing must be looked past. Thank you for your well write check up on this product. Tank you for yourincluded websites. Good job
