These two come up together because they touch the same health topic — not because they do the same job. Atenolol is a prescription medicine with approved uses on its FDA label. Astaxanthin is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Atenolol is prescribed for: Atenolol tablets are used to treat high blood pressure (hypertension) and angina pectoris (chest pain caused by narrowed coronary arteries). Lowering blood pressure reduces the risk of stroke and heart attack. Long-term use helps manage chronic chest pain. Atenolol is also used in hemodynamically stable patients with a definite or suspected acute heart attack (myocardial infarction) to reduce the risk of cardiovascular death.

Astaxanthin has been studied for:

• Stroke studied, not established Astaxanthin has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

  Astaxanthin for stroke

  Although there is interest in using oral astaxanthin for recovery from stroke, there is insufficient reliable information about the clinical effects of astaxanthin for this purpose.

• Heart failure studied, not established Astaxanthin has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

  Astaxanthin for heart failure

  Oral astaxanthin has only been evaluated in combination with other ingredients; its effect when used alone is unclear.

• Hypertension studied, not established Astaxanthin has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

  Astaxanthin for hypertension

  It is unclear if oral astaxanthin reduces blood pressure.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Atenolol on your own; if you are taking Astaxanthin for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Out of every supplement and medication people look up on HelloPharmacist, here is where these two land this week — and which way each has been moving.

Position among everything looked up on this site, not a measure of how commonly either one is used or how important it is. A supplement can climb this list because of a news story. It counts every request to the page, automated ones included, and nothing here identifies anyone.

Natural Medicines records Atenolol as a medicine that can lower these. This is not an interaction with Astaxanthin — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:
