What is Ashwagandha?

Ashwagandha is one of the most popular ancient remedies and has been used for centuries to alleviate stress, reduce swelling, lower blood pressure and boost the immune system. However, it is only recently that scientific studies have uncovered the true benefits of Ashwagandha and found it to contain anti-inflammatory and anti-oxidant properties.

When it comes to stress, anxiety or sleep, Ashwagandha should be at the top of your list. It can be used to alleviate both mental and physical stress, which results in better mood and energy as well as renewed focus and memory.

However, not all Ashwagandha supplements are equal and choosing the wrong kind can be an ineffective, costly mistake that may make matters even worse in rare cases.

Benefits of High Quality Ashwagandha

Ashwagandha Supplements can be a very effective and inexpensive way to boost your mental health. By choosing the right supplement, you may see an improvement from just 3-4 weeks.

What To Look For?

Ashwagandha Supplements are NOT all the same. It’s important to choose quality, proven formulas from trusted brands to see real benefits.

At Least 700mg of Ashwagandha Per Serving Choose a supplement that includes at least 700mg, with 800mg being the optimal dosage of Ashwagandha. This is the clinically studied dose that has shown real benefits.
Uses “KMS-66” Type Ashwagandha When choosing your supplement, make sure you keep an eye out for the type of Ashwagandha used. KMS-66 is the most potent and bioavailable root extract available. It is more expensive than other forms, yet much more effective as it keeps in tact all the natural attributes of the herb and is more easily absorbed.
Contains Supporting B-Vitamins Ashwagandha works well with supporting ingredients such as B Vitamins, including Riboflavin and B12 and they work together to boost overall effectiveness. B Vitamins are proven to help reduce tiredness, boost energy and alleviate stress or anxiety. This makes for an excellent combination with Ashwagandha.
Money-Back Guarantee It is important to buy from brands that stand behind their product. Without a guarantee, you could lose your money and end up with an ineffective product. It is recommended to look for brands that offer a 30-60 day money back guarantee.

What Should I Avoid?

Poor Formulations & Doses It is recommended to stay away from low potency formulas that offer less than 750mg of KSM-66 Ashwagandha. In addition, avoid formulas that fail to include supporting ingredients as they will be less comprehensive and therefore less effective.

Warning: Many cheap supplements may include misleadingly high doses of Ashwagandha. The truth is that they use a basic powder which is less bio-available. Therefore while the dosage may appear higher, it is actually less effective and therefore we recommend sticking to KSM-66 extract of 750mg+.
Artificial Reviews Watch out for product listings on Amazon and other marketplaces with fake reviews. When it comes to supplements, you are safer buying directly from trusted brands who are based in the UK. Buying from marketplaces or middle men companies gives you no guarantee when things go wrong.
