This is not medical advice
Everything on ragnarroak.com is published for general information. We are researchers and writers, not physicians, dietitians or pharmacists. Nothing here is medical advice, diagnosis or treatment, and nothing here should replace a conversation with a qualified healthcare professional who knows your history.
Speak to a doctor first if any of these apply
- You are pregnant or nursing
- You are under 18
- You take prescription medication of any kind
- You have a diagnosed medical condition
- You are being treated for a heart condition or take nitrates — L-arginine acts on the same blood-vessel pathway
- You have surgery scheduled
Dietary supplements are regulated differently
In the United States, dietary supplements are not subject to the pre-market approval process that applies to pharmaceutical drugs. The FDA does not approve dietary supplements for safety or effectiveness before they are sold. Any badge or claim suggesting a supplement is "FDA approved" is inaccurate — what a manufacturer can legitimately state is that a product is made in an FDA-registered facility, which is a statement about the premises, not about the product.
A supplement is not a treatment
RagnarOak is a dietary supplement, not a treatment for erectile dysfunction or low testosterone. Both are medical conditions with real causes worth diagnosing — cardiovascular disease and diabetes among them — and a gummy is not a substitute for finding out which one you have. If you take nitrates, blood-pressure medication, blood thinners, a thyroid medicine or a sedative, or you manage a heart condition, speak to a clinician before adding this or anything like it.
Individual results vary
Response to any supplement depends on diet, genetics, existing health status, medication and consistency of use. Results described on this site are not guaranteed and may not be typical.
Never delay medical care
If you have a health concern, seek professional advice. Do not disregard or delay medical care because of something you read here. In an emergency, contact your local emergency services immediately.
