We map 21 health goals — sleep, immune support, energy, joints, heart, bone, mood and more — to the supplements people commonly take for each, then rank every option by real cost per dose, not sticker price. We make no health claims; every nutrient links to its NIH-sourced facts.
Sleep
Nutrients people commonly take to support sleep and relaxation. We make no medical claims — each is ranked by real cost per dose, with NIH-sourced facts on every nutrient page.
Immune support
Nutrients commonly taken for immune support. This is a cost-per-dose value comparison, not medical advice — see each nutrient page for NIH-sourced detail.
Energy
Nutrients involved in normal energy metabolism that people commonly supplement. B vitamins help the body USE energy from food; they do not add energy unless you are short. Ranked by cost per dose.
Stress, anxiety & mood
Nutrients and botanicals people commonly take for stress, anxiety and low mood. We make no treatment claims — each is ranked by cost per dose, with sourced facts on its nutrient page. Anxiety is a medical matter; talk to a clinician. Not medical advice.
Focus & memory
Nutrients commonly taken for focus and cognition. A value comparison, not medical advice. Ranked by real cost per dose.
Joint support
Nutrients people commonly take for joint comfort and mobility. No treatment claims — ranked by cost per dose with sourced nutrient facts.
Heart health
Nutrients commonly taken for heart and circulatory health. This ranks each by cost per dose and is not medical advice.
Bone health
Nutrients involved in bone health that people commonly supplement — calcium and vitamin D for absorption, plus vitamin K2, magnesium and collagen. Ranked by cost per dose; see each nutrient page for NIH-sourced intake and upper-limit facts. Not medical advice.
Gut health
Supplements people commonly take for digestive and gut health. A cost-per-dose value comparison, not medical advice.
Hair growth, skin & nails
Nutrients commonly taken for hair growth, hair loss, skin and nails — such as biotin, collagen, iron and vitamin D (low iron and vitamin D are linked to hair shedding). Ranked by cost per dose, with NIH-sourced facts on every nutrient page. Not medical advice.
Muscle & strength
Supplements people commonly use to support training, muscle and strength. Ranked by real cost per dose (per gram for powders), not sticker price.
Prenatal & pregnancy
Nutrients commonly recommended before and during pregnancy. Folate before/early pregnancy is widely advised; this page ranks options by cost per dose and is not medical advice — talk to your clinician.
Eye health
Nutrients commonly taken for eye health and vision — lutein and zeaxanthin (the macular carotenoids), plus omega-3, zinc, vitamin A and astaxanthin. The AREDS research is the usual reference point. A cost-per-dose value comparison, not medical advice.
Blood-sugar support
Nutrients and botanicals people commonly take for blood-sugar support. No treatment claims — ranked by cost per dose. Speak to a clinician if you manage blood sugar.
Longevity
Supplements popular in the longevity space. Evidence varies and we make no claims — this ranks each by real cost per dose so you do not overpay.
Testosterone support
Nutrients people commonly take to support normal testosterone and male vitality — for example zinc, magnesium and vitamin D, where a deficiency can lower testosterone, plus botanicals like ashwagandha and fenugreek. We make NO claim that supplements raise testosterone or treat low-T; each is ranked by cost per dose. Speak to a clinician about low testosterone. Not medical advice.
Men's health
Supplements men commonly take for general health and performance. A cost-per-dose value comparison, not medical advice — see each nutrient page for NIH-sourced facts.
Women's health
Supplements women commonly take for general health — including iron, calcium, folate and vitamin D. Ranked by cost per dose; not medical advice. If pregnant or trying, see the prenatal hub and your clinician.
Inflammation support
Nutrients people commonly take for inflammation and recovery, such as omega-3 and curcumin (turmeric). We make no treatment claims — each is ranked by cost per dose. Not medical advice.
Weight management
Supplements people pair with diet and exercise for weight management. We make NO fat-burning or weight-loss claims and we exclude stimulant "fat burners" — these are everyday nutrients (protein, fibre and the like) ranked by cost per dose. Not medical advice; weight management is a clinical conversation.
GLP-1 companion
Nutrients people taking GLP-1 medications (such as semaglutide or tirzepatide) most often ask about — reduced appetite can lower protein and micronutrient intake, so protein, magnesium, electrolytes, fibre and key vitamins come up frequently. This is a cost-per-dose value comparison, NOT medical advice: talk to your prescriber, and never change or stop a medication because of a supplement.
