Herbal wellness and adaptogenic herbs are trending because of something herbalists have known all along, and modern science confirms—herbs offer powerful health and wellness benefits.

Herbs can influence our health in many exciting ways, helping keep our minds sharp, our bodies nimble, healthy and energized, and promoting an elevated sense of wellbeing by reducing the impact of stress on our bodies and minds.1,2,3

The scientifically-proven benefits of herbs are the driving forces behind our new line of scientifically-researched herbal formulas with clinically-studied ingredients for supporting joint, heart, energy, and brain health support. Each blend includes simple, science-backed ingredients specifically formulated from synthetic-free, natural plant sources.

Are you ready to harness the power of nature, proven by science? Read below to learn why we chose the herbs we’ve included in our condition-specific herbal blends, Swanson Pure Science Herbals, plus learn about adaptogenic herbs and how they can help combat mind and body stress.

What are Adaptogenic Herbs and Adaptogens?

Let’s face it—modern life can be stressful. Adaptogenic herbs may just be the answer we’ve all been seeking. Adaptogenic herbs are unique herbs, also known as “adaptogens,” that are especially good for helping our minds and bodies deal with daily stressors.1 They help bring a sense of balance and calm to our modern lives, and help protect us from the effects of stress.

Adaptogenic herbs assist with the body’s stress response, and many of them help reduce cortisol levels while normalizing related physiological functions like nervous system stimulation due to stress.1,4

That’s important for helping us feel better amidst the stresses of modern life, but less stress may mean better health and anti-aging benefits too, since stress makes us age faster!5,6 Plus, experts estimate that between 75%-90% of all doctor visits are due to stress-related health concerns.6

Mitigating stress should be a key consideration in everyone’s wellness routines. Two of our Pure Science Herbals, Pure Brainpower and Pure Energy, contain adaptogenic herbs. You can read more about these beneficial herbal blends below.

What Are Condition Specific Herbs and Why Should I Try Them?

Scientific research has shown that certain herbs are well-suited to help with specific areas of health. For example, Boswellia is an herb known for supporting healthy connective tissues, making it an excellent inclusion for joint-supporting supplement formulas.2 Grape seed extract helps support healthy blood pressure within the normal range and offers cardio-protective benefits, and Ginkgo-bilbo is used to support cognitive function.7,8

But we’ve taken traditional herbal formulas a step further. Our experts have harnessed some of nature’s most effective ingredients and combined them in powerful herbal blends that are uniquely suited for supporting particular areas of health. That is the core of Swanson Health’s Pure Science Herbal Formulas.

So, why should I supplement with condition-specific herbal blends? Because herbs can target your unique health needs in a nature-sourced and scientifically-backed way. Herbs have qualities that can comfort and rejuvenate your body. Try them and see for yourself!

Explore the herbs & botanicals in Swanson Pure Science Herbals Pure Blood Sugar formula:

Chromium: According to studies, chromium may support healthy blood glucose levels already within the normal range. These studies reported that chromium given to human subjects with a known chromium deficiency resulted in improved glucose levels.27

Berberine: A quaternary ammonium salt, berberine can be found in foods and herbs like Oregon grape, turmeric, goldenseal and the roots, stems and bark of various plants.

Research indicates that berberine is useful in promoting increased insulin receptor expression as well as more effective utilization of blood glucose.28

Gymnema Sylvestre: Found in the forests of Africa, Australia and India, Gymnema sylvestre is a shrub and its leaves have been used as an herbal tonic for centuries. A part of India’s Ayurvedic tradition, it is commonly used today for its ability to promote healthy blood glucose levels already within the normal range.29 Studies have shown that Gymnema sylvestre supports the blocking of receptors within the intestines that absorb sugar as well as boosting insulin levels.29 Further, one of Gymnema sylvestre’s active components is gymnemic acid, which promotes the suppression of sugar receptors in your taste buds, which may reduce the appeal of sweet and sugary foods.29

Swanson Pure Weight Herbal Blend

Get an edge in your quest to reach a healthy weight. Along with a healthy diet and exercise, Swanson Ultra Pure Weight is an excellent way to promote weight management by introducing clinically-studied herbal weight support ingredients. These carefully selected herbal ingredients include capsicum extract, Withania somnifera extract, green tea extract and naturally-sourced caffeine.

Explore the herbs & botanicals in Swanson Pure Science Herbals Pure Weight formula:

Capsicum: Capsicum is a compound found within the red pepper herb. It is used for a wide variety of health-boosting purposes, but has gotten a lot of attention for its ability to support a healthy weight. Studies have shown that capsicum can boost metabolism as well as healthy weight maintenance.30 Swanson Ultra Pure Weight uses a distinctive form of capsicum extract that delivers the metabolic benefits of red pepper, but without the potential for GI irritation or burning.

Withania Somnifera: Also known as ashwagandha or Indian Ginseng, Withania somnifera is an adaptogenic herb that can help enhance a healthy weight regimen. Withania somnifera’s effects on weight are linked closely to its ability to support stress reduction. Daily stressors can lead to increased stress hormones like cortisol, which, in turn, can contribute to stress-related weight gain. Studies indicate that by taking a Withania somnifera supplement, individuals may reduce the production of stress hormones, therefore leading to positive results when it comes to promoting weight management.31

Green Tea: Green tea is an antioxidant-rich beverage that’s been enjoyed for centuries dating back to ancient China. Researchers have studied the effects of green tea and discovered it can boost fat burning within the body. Experts say both the caffeine and epigallocatechin gallate (EGCG) found within green tea work together to promote the inhibition of an enzyme that breaks down norepinephrine, a hormone that promotes fat breakdown.32

Caffeine: Widely known for the jolt of energy it provides, caffeine can also play an important role in fat breakdown. Caffeine helps increase epinephrine in the bloodstream which boosts the nervous system’s ability to send signals to fat cells, encouraging them to burn fat for energy.33


Embrace the herbal power of Swanson Pure Weight, featuring four clinically-studied ingredients to empower your weight maintenance goals. Featuring capsicum, Withania somnifera, green tea extract and naturally-sourced caffeine, this formula, along with a healthy diet and exercise, will support fat burning, a healthy metabolism and healthy weight management.

Explore the herbs & botanicals in Swanson Pure Science Pure Digestion formula:

Bromelain: A naturally-occurring mixture of proteolytic enzymes found within the fruit stem of pineapples. Bromelain is especially useful in promoting the breakdown and digestion of proteins.34 Studies also suggest that bromelain may promote the body’s ability to fight minor digestive concerns.34

Perilla Leaf: A member of mint family, Perilla frutescens is a common ingredient in the culinary tradition of many Asian cultures, but it also is an excellent digestive aid. Research shows that perilla extract helps support the body against occasional digestive discomfort, bloating, GI rumbling and feelings of fullness while boosting daily regularity.35

Grape Seed Extract: Grape seed extract has been rigorously studied for its benefits to digestive health. According to these studies, grape seed delivers a prebiotic effect that boosts gut health and feeds the beneficial digestive flora colonies and probiotic bacteria within the gastrointestinal tract.36
