Wellness picks, explained

What each product is actually for

Five categories, fifteen products. For each one: what it is, what people take it for, the dose range you will see on labels, and what to look for before you buy. No brand is better than the habit it supports — this page is here so you can choose on evidence rather than on packaging.

Read this part first

This is general educational information, not medical advice, and Evelyn Hart is a fictional AI-generated personality — nothing here describes a real person's results. Supplements are not necessary for everyone. If you take prescription medication, are managing a condition, or are pregnant, speak with a clinician before starting anything on this page. Several products below interact with common medications, and those are flagged.

Weight & metabolism

After 50 the usual problem is not willpower, it is that meals get smaller while protein needs stay the same. Everything in this group makes a meal more filling or more complete. Nothing here burns fat, and anything that claims to is best avoided.

Protein powder

Whey isolate or plant blend

The single most useful product in this group. Protein preserves muscle during weight loss and is the most filling of the three macronutrients, so meals built around it tend to need less willpower.

  • Typical serving20–30 g protein
  • Daily target1.2–1.6 g per kg body weight
  • CheckProtein per scoop, not per 100 g
  • Ask first ifYou have kidney disease
See protein options

Fiber supplement

Psyllium husk or glucomannan

Most people eat around half the fiber they need. Fiber slows digestion, supports regularity and blunts the rise in blood sugar after a meal, which is why it shows up in both this group and the next.

  • Typical dose5–10 g per day
  • Build upStart low, add water
  • CheckNo added sugar or sweetener load
  • Ask first ifYou take medication — space it two hours apart
See fiber options

Keto electrolytes

Sodium, potassium, magnesium

Low-carb eating flushes sodium, and the headaches and flatness people call "keto flu" are usually that. Only relevant if you are actually eating low-carb; on a normal diet this is unnecessary.

  • Look forSodium above 500 mg per serving
  • AvoidSugar-heavy sports mixes
  • WhenFirst weeks of low-carb, hot weather
  • Ask first ifYou have high blood pressure or kidney disease
See electrolyte options

Blood sugar & metabolic support

This is the group people ask about most and the one that needs the most caution. These are not alternatives to prescribed treatment, and two of the three interact with common diabetes medication. A fasting glucose and HbA1c test from your doctor tells you far more than any label.

Berberine

Plant alkaloid, capsules

The most studied item here. Trials report modest improvements in fasting glucose and HbA1c, usually alongside diet changes rather than instead of them. It is often marketed as a natural substitute for metformin, which is not an accurate claim.

  • Typical dose500 mg, two or three times daily
  • Take withMeals, to reduce stomach upset
  • CheckThird-party purity testing
  • Ask first ifYou take any medication — berberine affects how many drugs are cleared
See berberine options

Myo-inositol

Powder or capsules

Best known in women's health for insulin sensitivity, with most of the evidence coming from studies in PCOS. Generally well tolerated, and gentler on the stomach than berberine.

  • Typical dose2–4 g per day
  • FormPowder dissolves; capsules mean many pills
  • Give itEight to twelve weeks
  • Ask first ifYou are on glucose-lowering medication
See inositol options

Chromium picolinate

Trace mineral, capsules

Cheap, widely sold and the weakest of the three on evidence. Results in trials are inconsistent, and the clearest benefit appears in people who were genuinely deficient. Worth knowing before you spend on it.

  • Typical dose200–400 mcg per day
  • EvidenceMixed; modest at best
  • CheckDose in mcg, not mg
  • Ask first ifYou have kidney or liver disease
See chromium options

Skin & beauty

Three products do most of the work, and one of them does more than the other two combined. A short routine you repeat every day beats a shelf of serums you use occasionally.

Broad-spectrum sunscreen

SPF 30 or higher, daily

The one with the strongest evidence behind it, by a wide margin. Most of what people call aging skin is accumulated sun exposure, and this is the only product on the page that prevents it rather than treats it.

  • MinimumSPF 30, broad spectrum
  • ReapplyEvery two hours outdoors
  • CheckA texture you will actually wear daily
  • NoteNeeded on cloudy days too
See sunscreen options

Retinoid

Retinol or retinaldehyde, nightly

The best-evidenced active for skin texture and fine lines. It also needs patience and a slow start: two or three nights a week at first, then more, and always with sunscreen the next morning.

  • Start at0.1–0.3 % retinol
  • Frequency2–3 nights a week, then build
  • Give itTwelve weeks
  • Avoid ifPregnant or breastfeeding
See retinoid options

Vitamin C serum

L-ascorbic acid, mornings

An antioxidant layer under sunscreen, with reasonable evidence for tone and brightness. It oxidises easily, so packaging matters more than the price — a clear dropper bottle on a bright shelf is already losing potency.

  • Typical strength10–20 %
  • PackagingOpaque or dark glass, airtight
  • Discard whenIt turns orange or brown
  • Pair withSunscreen, every morning
See vitamin C options

Daily essentials

The boring group, and the one most worth getting right. These correct common shortfalls rather than add anything extra, and two of the three are blood-test questions rather than guesses.

Vitamin D3 with K2

Softgels, with a meal

Low vitamin D is common in anyone who spends their days indoors, and it shows up as flat energy long before anything else. Vitamin K2 is often paired with it to direct calcium toward bone.

  • Typical dose1000–2000 IU daily
  • Take withFood containing fat
  • Test25(OH)D before and after
  • Ask first ifYou take blood thinners — K2 interacts with warfarin
See vitamin D options

Omega-3

Fish or algae oil, high EPA

Worth it when fish is rare in the week, which for most people it is. Buy on the EPA and DHA figures printed on the back, not on the size of the capsule or the word premium on the front.

  • Typical dose1000 mg combined EPA + DHA
  • CheckThird-party purity and freshness
  • StoreCool and dark; it oxidises
  • Ask first ifYou take anticoagulants
See omega-3 options

Vitamin B12

Methylcobalamin, tablets

Absorption drops with age and drops further on long-term metformin or acid-reducing medication. Deficiency looks like fatigue and brain fog, so it is worth testing rather than assuming either way.

  • Typical dose250–1000 mcg daily
  • More likely low ifYou eat little meat, or take metformin or PPIs
  • TestSerum B12
  • NoteExcess is excreted, but testing still beats guessing
See B12 options

Sleep & recovery

Everything on this page is downstream of sleep. These three make the night easier; none of them outperforms a dark room and a bedtime you keep.

Magnesium glycinate

Capsules, an hour before bed

The glycinate form is the one that settles rather than sending you to the bathroom — that is the oxide form, which is cheaper and poorly absorbed. Useful for legs that have been under load all day.

  • Typical dose200–400 mg elemental
  • AvoidMagnesium oxide
  • CheckElemental mg, not compound weight
  • Ask first ifYou have reduced kidney function
See magnesium options

Glycine

Amino acid powder

A small body of research links it with falling asleep faster and better-rated sleep quality. Cheap, mildly sweet, and easy to stir into water. Not a sedative, so expect subtlety rather than knockout.

  • Typical dose3 g before bed
  • EvidenceSmall but consistent studies
  • FormPowder is far cheaper than capsules
  • NoteTry it for two weeks before judging
See glycine options

L-theanine

Amino acid from tea, capsules

Aimed at the wound-up feeling that keeps people awake rather than at sleep itself. It is the compound that makes green tea calming despite the caffeine, and it does not cause grogginess the next day.

  • Typical dose100–200 mg
  • WhenEvening, or with afternoon coffee
  • CheckDose per capsule
  • Ask first ifYou take blood pressure medication
See theanine options

What is not on this page

These come up in my messages constantly. None of them earns a place, and knowing why saves you more money than any discount code.

  • Fat burnersCaffeine, a diuretic and a price tag. They cost you sleep, and lost sleep costs more than they return.
  • Detox teasA laxative in a nice box. Your liver and kidneys already do this, and they do it better.
  • Hair and nail gummiesSugar with a trace of biotin, usually at a dose high enough to distort thyroid blood tests and little else.
  • Collagen for wrinklesReasonable evidence for joints and tendons, thin evidence for the face. Sunscreen and a retinoid do far more for skin.
  • Multivitamins as insuranceSmall doses of everything, enough of nothing. Test, then fix what is actually low.
