You might be wondering

How long does a bottle last?

Every jar contains a 30-day dosage, consisting of 60 capsules.

We recommend taking 2 capsules in the morning along with a glass of water or juice to experience the benefits throughout the day.

When will I notice results?

While certain customers may notice benefits as early as the first month, the complete spectrum of advantages that this supplement provides becomes evident during the third month - and beyond. This is when your brain establishes its new baseline.

Water-soluble vitamins, such as B-vitamins, are swiftly absorbed by the body. Conversely, fat-soluble vitamins like vitamin D and omega-3 require more time to attain their optimal levels, emphasizing the importance of patience in this process.

Here's what to expect:

  • 1-4 Weeks : Improved mood. You’ll feel more optimistic. 
  • 4-8 Weeks: Experience improved ability to deal with stressful situations.
  • 8 Weeks + : Noticable changes in response to anxiety. Improved sleep and emotional balance.
What makes this supplement different from others?

We exclusively use plant-based nutrients in their most effective active forms to ensure optimal absorption by your body, allowing you to derive maximum benefit from all the nutrients.

Our products are not only clean but also free of allergenic substances, toxins, GMOs, and gluten. Moreover, we steer clear of fillers and bulking agents because we are committed to delivering only the highest quality for your brain and body. Furthermore, we regularly review and refine our formula every three months to provide you with the finest product.

Are there any negative side effects?

In internal studies, no negative side effects were reported for our treatment. In fact, the ingredients in our supplement often come with what we call “side benefits” such as better sleep, focus, energy, and mood.

Can I take the supplement with other medications?

While our supplement is generally safe for most individuals, it is essential to consult with a healthcare provider if you are taking other medications or supplements. They can advise on potential interactions and ensure the supplement is suitable for your specific health needs.

How do subscriptions work?

Consistency is key to great results. Our products are designed to build over time so we recommend committing to at least 3 months to see the full health benefits.

By signing up to subscription for any product, you agree to automatic renewal every 30 days. For your first order, we will send you a shipment with a 30 day supply of your chosen products, and your subscription will automatically continue to renew every month. You may choose to cancel at any time after the initial minimal term of 2 months. 

Following the initial minimum term of 2 months, if you wish to cancel your subscription, you can do so by emailing shop@haelf.com at least 48 hours before your next order renewal or by cancelling in your account. 

How do I take this supplement?

For optimal results, take the supplement as directed in our treatment guide. Usually, it involves taking a specified dosage with water once a day. Avoid exceeding the recommended dosage unless advised by a healthcare professional.

Do you offer a money-back guarantee?

Yes, we stand behind the quality and effectiveness of our product. If you are not satisfied with the results after using our supplement as directed, we offer a money-back guarantee within a specified time frame. Please check our refund policy for more details.
