Why do these products work?

Rhubarb Complex® alone is an award winning formula that has over 5k+ verified reviews from people who simply love it. However, the winter can be harsh on our bodies owing to excessive carbohydrate intake, more time indoors and less exercise. We have just finished the festive period so for many there's a high chance that our livers have also been working overtime. That's why the experts at Twenty First Century Herbs have added Slenderize® and Apple Cider Vinegar to this fantastic winter pack to help stave off that 'Winter Coat' whilst helping give the liver and digestive system a gentle overhaul and cleanse.

How do I take it?

It’s easy, just take between 1 - 2 capsules right before your evening meal. 

You say ‘move your bowels’. Does this mean I will be constantly going to the loo?

No, our formula is gentle and designed to be taken during everyday life and can provide natural constipation relief. During the first 2 days you may go a little more, but this will regulate very quickly. All our customers, including ourselves, take Rhubarb Complex whilst working, socialising or travelling without any problems whatsoever.

Is Rhubarb Complex just a laxative?

No! Rhubarb Complex is NOT a laxative, it is an award winning digestive formula based on 85 years of clinical experience. Rhubarb Complex is designed to effectively address digestive issues, gently regulating the bowels and detoxing your body.  

Can I take it alongside any medication?

Yes, there are no contraindications with any medication.

Can I take more than 1 capsule?

You can, but there is no need as long as you are moving your bowels once or twice a day. If you aren’t, then increase to 2 capsules. 

Are the supplements vegetarian friendly?

Yes, all our products are vegan and vegetarian friendly. Our ingredients are 100% natural and have been handpicked by leading herbalists, based on 85 years of expertise.

Are the capsules Gluten Free?

Yes, Rhubarb Complex is 100% Gluten Free.

Is Rhubarb Complex Dairy Free?

It most certainly is, we pride ourselves on Rhubarb Complex being dairy-free!

I'm pregnant/lactating. Can I still take Rhubarb Complex?

We would encourage you to consult with a medical practitioner before taking Rhubarb Complex.

What if I have questions whilst taking it?

We pride ourselves on working with our customers every step of the way. We don’t just leave you once you have bought the product. We are always available via phone, email or our online chat if you have any questions.

Do I need to follow a specific diet whilst on the Rhubarb Complex?

We don’t advocate a strict diet whilst on the complex, as our products are designed to allow people to survive the 21st Century where toxins are unavoidable. However, for optimum results, we would say to avoid processed foods where possible and also to watch your intake of wheat and yeast as we find these to be the main culprits of digestive complaints.

I struggle to take capsules, does this come in any other form?

Rhubarb Complex is only available in capsule form, however, the capsules can easily be pulled apart and the contents can be mixed with food or juice and the results will be unaffected.

Twenty First Century Herbs Vegan Friendly Food Supplements


The ancient Egyptians were recognised as inventors of original Apple Cider Vinegar, or at least they were the first civilisation to recognise its medical benefits. Records show that as early as 3000 BC, the Egyptians used Apple Cider Vinegar as an antiseptic and also as a weight loss agent. Today, apple cider vinegar is almost exclusively taken by people who want to shed a few pounds. To avoid the strong acidic taste we have expertly created our Apple Cider Vinegar Complex into capsules. This means you can reap all the benefits but in a form that is much easier to swallow and digest. Our capsules provide nutritional support for dieters and in addition contain Lecithin and Vitamin B6 to help emulsify dietary fat and metabolise protein and lipids. They also contain Kelp, a rich source of Iodine which helps maintain normal thyroid function.

Twenty First Century Herbs Vegan Friendly Food Supplements
"Scientific Research of Slenderize® has led to its increasing popularity as a dietary supplement. This is because, when taken  as part of a low-calorie diet, scientific tests have determined that Slenderize® aids weight loss. Our formula increases the feeling of fullness, therefore encouraging the user to consume fewer calories."

Like other soluble fibres, it’s believed to promote weight loss in several ways :

    1. It’s very low in calories.
    2. It takes up space in your stomach and promotes a feeling of fullness (satiety), reducing food intake at a subsequent meal
    3. It delays stomach emptying, contributing to increased satiety 
    4. Like other soluble fibres, it reduces the absorption of protein and fat
    5. It also feeds the friendly bacteria in your intestine, which turn it into short-chain fatty acids like butyrate, shown to protect against fat gain in some animal studies

Does It Really Work?
Several randomised yet controlled trials have studied the effects of Slenderize® on weight loss. These types of studies are the gold standard of scientific research in humans.

In the largest study, 176 healthy but overweight people on a calorie-restricted diet were randomly assigned Slenderize® or a placebo. Weight loss was significantly greater among those who supplemented with Slenderize®.

Several other studies agree with these results. Slenderize® caused modest weight loss in overweight and obese individuals when regularly ingested before a meal.

It’s particularly effective when combined with a weight-reducing diet.

According to a systematic review of 14 studies, Slenderize® can lower:

  • Total cholesterol by 19 mg/dL (0.5 mmol/L).
  • “Bad” LDL cholesterol by 16 mg/dL (0.4 mmol/L).
  • Triglycerides by 11 mg/dL (0.12 mmol/L).
  • Fasting blood sugar by 7.4 mg/dL (0.4 mmol/L).

It primarily reduces blood cholesterol by decreasing the absorption of cholesterol in your gut.

As a water-soluble fibre, Slenderize® has also been successfully used to treat constipation.
