Shop Heart & Circulation

Your heart is a muscle that never gets a rest day, and the circulation it drives is how oxygen and nutrients reach every other part of you. Supplements play a small part in that system, and this collection is written at that scale: six products gathered around heart and circulation, each described by what its own panel prints, all meant to sit beside the habits that carry most of the load — moving most days, eating fish and plenty of plants, and sleeping enough. The shelf follows three routes. Fish oil supplies EPA and DHA, long-chain omega-3 fats the NIH Office of Dietary Supplements identifies as parts of the membrane around every cell, with work to do in the heart and blood vessels among other places.

CoQ10 is a compound the body makes for itself, and the National Center for Complementary and Integrative Health notes that the heart holds some of the highest levels of it in the body. The third route runs through nitric oxide, a molecule the body uses to widen blood vessels and increase blood flow. The same NIH office counts beets among the richest food sources of nitrate, part of which the body turns into nitric oxide, and notes that the body makes arginine from citrulline and converts some of that arginine into nitric oxide too.

Read this shelf the way you would read its labels, because the number that matters is rarely the biggest one on the bottle. Omega-3 Fish Oil Softgels say 1,000 mg, and that is the weight of the whole oil concentrate; the rows worth counting sit underneath it, 180 mg of EPA and 120 mg of DHA per softgel, with sardines and anchovies named in the allergen line. CoQ10 Ubiquinone Capsules put the form inside the row, 200 mg of coenzyme Q-10 as ubiquinone in one vegetable capsule, with rice flour the only other thing inside the shell. Trans-Resveratrol Capsules print a 600 mg resveratrol complex from Japanese knotweed root that is 50% trans-resveratrol, which works out to 300 mg of the trans form per capsule. It is also the ingredient here with the most open questions: a National Institute on Aging research summary notes that the benefits reported for resveratrol so far come mostly from animal studies, and that more research is needed to know whether it has benefits in people, so this page describes its panel and makes no claim past it.

On the blood-flow side, L-Citrulline & L-Arginine Capsules keep three amino-acid forms on three rows — 400 mg of L-citrulline DL-malate, 350 mg of L-arginine hydrochloride and 50 mg of L-arginine alpha-ketoglutarate in two capsules — and Organic Beetroot Capsules hold 1,300 mg of organic beetroot powder on a one-row panel. The one figure neither beet product here prints, the capsules or the Beetroot & Hibiscus Powder, is nitrate, and we will not estimate a number a label does not carry.

Then pick one route rather than all three. Fish oil suits people who rarely eat oily fish; CoQ10 or resveratrol suits someone who wants a single ingredient they can read in one line; citrulline or beetroot fits a routine built around active days. Take it the way its label says, because the labels here disagree on timing: the fish oil is one softgel twice a day with meals, the CoQ10, resveratrol and beetroot capsules go 20 to 30 minutes before a meal, the citrulline capsules ask only for a glass of water, and the beet powder is one scoop in cold water, drunk within ten minutes of mixing. At those directions the fish oil supplies 600 mg of EPA and DHA a day, well under the FDA’s 5 g figure for supplements covered in the questions below.

If you take a blood thinner or any prescription, read the medication answer there before you start. Give whichever you choose several steady weeks, and let Subscribe & Save keep it stocked at 10% off; you can cancel from your account anytime. CoQ10 and resveratrol also sit in the NAD+ and longevity collection, beside NAD+ and NMN, if the cellular-energy side of their story is the one you are shopping for. Every figure above is read straight off a panel you can check on its product page, and why this page stops at “support” and never says more explains the line we hold.
