A: RLC Labs is dedicated to supplying the highest quality medications possible, which is why we carefully source thyroid only from the U.S. and Canada. All sourced materials comply with the mandated government standards of their respective countries of origin and meet all requirements set by the USDA. We do not, nor have we ever, sourced thyroid from China.

A: Yes, both medications are free of all glutens.
A: Lactose is not added to our formula but it is already present in Thyroid USP raw material as a diluent per USP (United States Pharmacopeia). Lactose is not contraindicated for individuals with allergies to dairy, as lactose is a milk sugar (vs. dairy allergies which are caused by proteins in milk). It is, however, contraindicated for individuals with lactose intolerance. We have had many physicians reporting no side effects while using Nature-Throid with lactose intolerant patients. The amount is very small – less than 5 mg. per 1 Grain vs. 12,000 – 15,000 mg. in a typical 8 fl. oz. glass of milk.

A: Use as prescribed by your doctor. Take as a single dose on an empty stomach, at least 30-60 minutes before consuming food or caffeine. Some medications and supplements may lower the effectiveness of WP Thyroid and Nature-Throid when taken simultaneously, so it is important to take WP Thyroid or Nature-Throid at least one hour before any other medication. Calcium supplements, iron products, or antacids need to be taken four hours apart.

A: Store WP Thyroid and Nature-Throid at room temperature, 59°-86°F (15°-30°C), away from heat, moisture, and light. Dispense in tight, light-resistant containers as defined in the USP/NF. Keep out of reach of children and pets.
A: Nature-Throid and WP Thyroid are natural medications that use Thyroid USP, naturally derived thyroid hormones, as the active ingredient. Just like anything else from nature, batches of these medications will never be identical and may even differ in coloring, or "speckling", and even in smell. These are only sensory differences and do not affect efficacy. Since WP Thyroid is uncoated and formulated with minimal pure ingredients, the tablets can change color by absorbing ambient humidity. If the tablets are stored in their original container and at room temperature (59° (15°) – 86° F (30° C) with an ambient humidity of 10-65%, no discoloration occurs. However, exposed tablets outside of proper storage conditions still conform to USP specifications for both T4 and T3 potency and stability. You can find full Prescribing Information and ingredient lists for WP Thyroid and Nature-Throid on their respective pages. Please consult with your healthcare provider if you have any medical or health-related questions.

A: RLC Labs utilizes USDA and CFIA-certified pigs, which are treated humanely and not given blanket hormones or antibiotics unless specifically needed. You can learn more about USDA standards here and CFIA here.
A: No, but we understand the importance of organically raised pigs and hope to have an organic option available in the future.

Warnings: Don’t Take For
Use WP Thyroid® and Nature-Throid® exactly as prescribed. Unless otherwise directed by your doctor, do not stop taking either medication or alter how often it’s taken. Many factors can contribute to the length of time symptoms are alleviated, though generally people feel an improvement within a few weeks. For some, though, improvement in symptoms may take up to three months. Your doctor will determine which dose is right for you. If any life changes or new symptoms occur, consult your doctor to adjust your dose. Continue to see your doctor until your dosage levels prove stable based on your lab work, then continue to see your doctor at their request. Thyroid replacement therapy is usually taken for life.
