Stress Relief is a tablet supplement which aims to provide relief from symptoms of stress. It’s created by Natra Bio. It’s not clear where the company is from. Product labels say Shelburne Falls, Massachusetts; other websites list locations in Washington, Arizona, and Utah. Their parent company, Elephant Pharmacy, is based out of California. Natra Bio says they’ve been in business since 1979, focusing on homeopathic products and quality manufacturing processes. Most homeopathic items are very safe and have high levels of purity.


1) Quick Overview

Active ingredients include Chamomilla, Kali Phosphoricum, Calcarea Carbonica, and Silicea. Kali Phosphoricum refers to Potassium carbonate, which is a white salt that has no known medical applications. Sometimes it’s used in the making of soap and glass. It’s not likely to reduce any symptoms.

Some of the ingredients in Stress Relief can also be found in anti-stress supplements like BHI Calming.

What’s Inside?

2) What’s Inside Stress Relief?

Stress Relief contains the following ingredients: Chamomilla 1X, Humulus lupulus 1X, Passiflora incarnata 1X, Avena sativa 4X, Cimicifuga racemosa 6X, Cinchona officinalis 6X, Kali Phosphoricum 9X, Calcarea Carbonica 12X, Silicea 12X, Inactive: Lactose, magnesium stearate.

3) Is Stress Relief Right for You?

Active ingredients include Humulus lupulus, Passiflora incarnata, Avena sativa, and Cimicifuga racemosa. Avena sativa is the wild common oat. Humulus lupulus is also known as hops a main ingredient of beer. It’s mostly used for taste and preservation, so it’s not really known if hops have medicinal qualities. It probably doesn’t reduce stress. Cimicifuga racemosa is known as black cohosh, black snakeroot, fairy candle, and various other names. It’s a flowering plant native to North America. It’s said to have analgesic, sedative, and anti-inflammatory properties, in addition to helping treat symptoms of menopause. There isn’t much solid evidence on its benefits or potential side effects.

Passiflora incarnata is known as maypop or purple passionflower. It’s a vine which has large fancy purple flowers, can grow fruits, and is popular with butterflies. They’re native to the southeastern United States. Passionflower has historically been used in folk medicines to reduce anxiety, insomnia, and some other problems. No conclusive studies have proven that it can treat stress or anxiety, but it may increase the effectiveness of sedatives. Passionflower contains flavonoids and amino acids, but in small amounts.

4) Stress Relief Benefits & Results


  • Natural product which doesn’t contain alcohol, sugar, or obvious allergens, although the lactose may be a problem for some people.
  • Natra Bio products are sold in over 750 stores across the United States, so it’s possible to find this item somewhere near you.


5) Stress Relief Product Warnings

  • Exactly the same ingredients as another product from this company, Insomnia Relief, except this product doesn’t have Valeriana officinalis or Silicea. It might be better to get the other item.
  • No evidence that homeopathic medicine is effective in any way, other than potentially providing a placebo effect.

6) Stress Relief Price

This is meant to be used whenever you feel stressed: “every 30 minutes until symptoms improve, then reduce to every 4 hours.” It’s possible to go through your box of tablets very quickly. This can become very expensive; in order for Stress Relief to have an average price, you can’t take more than 4 tablets a day. Even then, you have to buy two boxes to get a one month supply. There is a 90 day money back guarantee, and you be able to get free shipping. Overall this seems expensive compared to similar products, but price depends on usage.


7) Directions For Taking Stress Relief

Silicea is the chemical compound Silicon dioxide. It’s common in quartz, various living organisms, and sand. It doesn’t dissolve easily, which can cause health problems if inhaled, as it would stick to the lungs. If you eat or drink it, though, Silicea is considered non-toxic. It doesn’t have any known pharmaceutical benefits aside from helping tablets retain their shape during the manufacturing process. The compound comes in many forms and has a wide range of practical applications. But it won’t do anything to reduce stress. The same is true of Calcarea Carbonica (also known as impure Calcium Carbonate), a chemical compound found mostly in rocks and shells. It’s sometimes called “one of the three major remedies used in homeopathic treatments” but has no actual medical use, except as an antacid, or part of a calcium supplement. In this product, both Calcarea Carbonica and Silicea are diluted enough to not provide any noticeable benefits or detriments. They’re provided at a 12X (6C) scale, which means almost none of the substance exists in the product.

Final Thoughts

8) Final Thoughts on Stress Relief

It doesn’t contain significant amounts of active ingredients, so we can’t effectively judge if this product works. Being primarily salt and lactose means Stress Relief is considered safe for most people to use. It does have better concentrations of many ingredients compared to other homeopathic medicines, possibly almost as much as some herbal teas. Another product from Natra Bio might serve you better, since this product is so similar to others yet has fewer ingredients. It’s not expensive for one box, though. If you think Stress Relief might be for you, it doesn’t cost much to see what its effects are.
