How i-Throid®  Restores Balance

Cold hands. Weak muscles. Brittle, chipping nails. Painful constipation. Perpetual fatigue. If this sounds like your daily reality, you may be struggling with hypothyroidism – a thyroid gland imbalance.

That tiny butterfly-shaped organ at the bottom of your neck regulates all the hormones that control your energy, metabolism, body temperature, sleep, digestion, sexual function, and even hair and nail growth.

When this powerful gland lacks iodine, it can’t produce and secrete enough thyroid hormones to keep all these functions humming along – an imbalance that can have you spending all your time and energy trying to resolve one symptom after another.

The research team at RLC Labs studied the symptoms of this nutrient imbalance for years before producing highly bioavailable, rapid release relief in the form of i-Throid®. The premium formula contains clinically validated doses of iodine and iodide to rebalance an underactive thyroid for consistent, long-term relief and energy revival.

How i-Throid® works

Your thyroid gland has a boss: the pituitary gland, which produces the TSH (Thyroid Stimulating Hormone) that prompts the release of thyroid hormones T3 and T4 into your blood. Asking your healthcare provider to perform TSH testing is the first step to a healthy thyroid.

Once you assess your levels of TSH, T3 and T4 and discover a deficiency, you’ll know you’re suffering from hypothyroidism. In order to synthesize and secrete thyroid hormones your body requires a certain amount of tyrosine and mineral iodine.

In a healthy functioning thyroid, 2 tyrosine molecules (each containing 2 atoms of iodine) combine to create T4. Your T4 thyroid hormone consists of approximately 65% iodine, and your T3 hormone consists of approximately 59% iodine.

Without that iodine your thyroid malfunctions, disrupting the crucial conversion of T4 to T3. To help convert inactive T4 into active T3 (which is then able to enter your cells) you have to supplement your iodine deficiency.

Since iodine is not stored in the body, it must be obtained daily from diet in order to maintain healthy thyroid function and optimized hormonal balance.

This is precisely what i-Throid® can help you accomplish.

i-Throid® is a clinically validated formula that contains optimal amounts of:

  • iodide: most time-tested remedy for thyroid imbalance
  • free elemental iodine: enables optimal absorption by the body
  • potassium: facilitates the proper function of nerve and muscle cells

Once it’s allowed to bind with tyrosine, iodine enables your body to produce proper amounts of thyroid hormones again.1

i-Throid® is more versatile and effective than other products on the market because it’s customizable (available in two strengths: 12.5 mg and 6.25) and delivered in physician-certified vegetable capsules. It can also be taken with our a-Drenal® supplement.
