We do not use any artificial dyes on our tablets. Therefore, occasionally you may notice the color of some of the nutrients showing through the natural coating.

These spots may darken over time as the tablets are exposed to moisture or air, but they are not harmful. Tablets with spots on them are safe to take.

Our manufacturing facilities have cleaning and handling procedures in place for allergens to assure there is no cross contamination.

Our products undergo accelerated stability testing after the product has gone through the same “customer journey” of being shipped from our distribution center to the testing center through the postal service. This stability testing ensures that our products can withstand temperatures as high as 140 °F with relative humidity of 80% for a minimum period of three months without affecting safety or quality. It’s our guarantee to you that our products can travel safely in warmer temperatures.  

During seasons of high temperatures, it is not uncommon for softgels and capsules to become tacky during shipping and stick together. During our testing we found that this has not affected the nutrients inside the softgels or capsules. Once the product has cooled down, the softgels and capsules will loosen up by gently shaking the bottle. 

If you cannot find the scoop in your canister, it may be located underneath the powder near the bottom of the canister. You may need to use a utensil to locate the scoop.

Yes. All Theralogix products are FSA and HSA eligible.

Yes. Theralogix partners with Flex to allow payment using your Health Savings Account (HSA) or Flexible Spending Account (FSA). 

Please note: This option is available only for one-time purchases made through guest checkout. When using Flex, you may be required to complete a short health questionnaire to verify eligibility before checkout. 

Yes, the products themselves are eligible. However FSA/HSA cards cannot be used directly for subscription payments. 

Subscription purchases can be submitted for reimbursement with a Letter of Medical Necessity (LMN)

A Letter of Medical Necessity allows eligible purchases to qualify for FSA/HSA reimbursement when you cannot pay directly at checkout. 

With an LMN, your Theralogix products are treated as qualified medical expenses, similar to a doctor’s visit or prescription medication. 

Yes, when Flex is selected at checkout, you can use your FSA or HSA card like a regular credit card.

Yes. When checking out with Flex you have the option to choose Split Payment to determine how much is charged to each payment method.

No. There are no additional fees to use Flex.

If you’re not paying directly with your FSA/HSA card, you can submit your purchase for reimbursement using a Letter of Medical Necessity (LMN). 

A reimbursement link will be included on your receipt or next subscription shipment. Follow these steps: 

• Review your Letter of Medical Necessity (LMN) 
• Identify your HSA/FSA administrator 
• Log in to your administrator’s online portal 
• Locate the Reimbursement or Claims section 
• Submit your LMN and receipt 
• Wait for confirmation 
• Repeat for future receipts as needed 

Most LMNs are issued within 24–48 hours. 

In some cases, additional review may be required based on your qualification survey. If you don’t see your LMN, check your spam folder for an email from notifications@withflex.com. 

If you still need help, contact support@withflex.com

Reimbursement approval is determined by your FSA/HSA administrator, not Theralogix or Flex. Requirements and processing times vary by provider.

Flex is only available for: 

• One-time purchases 
• Guest checkout 
• U.S. customers 

If you are logged into an account, using a subscription, or outside the U.S., Flex may not appear. 

If your card is declined, try completing the purchase with a regular credit card and submit your receipt for reimbursement using an LMN. 

Declines are typically due to administrator rules, not product eligibility.
