Heart Condition & Thyroid Medication: A Direct Caution

2026 guide · HorseBoost Research Desk

If you have a heart condition or take thyroid medication, this formula's own materials are direct: talk to your doctor before starting.

Why this caution applies

The brand's own materials specifically flag heart conditions alongside blood pressure concerns, and Ashwagandha can interact with thyroid medication — two distinct, named cautions worth taking seriously together.

What to actually do about it

💊 Medical note: this formula contains Horny Goat Weed, which may lower blood pressure and interact dangerously with nitrates and ED medication; Ashwagandha, which can interact with thyroid medication, sedatives and immunosuppressants; and Tribulus Terrestris, which is not advised alongside hormone-sensitive conditions. Talk to your doctor before starting if you take any prescription medication.
