The 27 supplements VitSync works with

Each one is backed by published research and GB-authorised health claims where they exist. Each link goes to the product the app itself suggests. VitSync only recommends an ingredient once your signals support it. This page is the full menu.

Vitamin D3

25 µg (1000 IU) a day · 50 µg above 90 kg · Solgar

Vitamin D contributes to the normal function of the immune system. UK guidance is at least 10 µg a day through the darker months, and even 50 µg stays well under the 100 µg a day safe ceiling. Take it with a meal that has some fat in it.

Magnesium

200 mg elemental a day · Nu U Nutrition

Magnesium contributes to a reduction of tiredness and fatigue. Most of yours comes from food, and one tablet tops up the usual shortfall. The tablet and any electrolyte sachet together stay within the NHS guidance of 400 mg a day from supplements.

Vitamin C

500 mg a day · Lamberts

Vitamin C contributes to normal energy-yielding metabolism. UK adults need 40 mg a day. 500 mg leaves room below the 1000 mg a day above which UK guidance warns of stomach upset, because iron, collagen and electrolyte products often carry vitamin C of their own.

Zinc

10 mg a day · Just Vitamins

Zinc contributes to the normal function of the immune system and to the maintenance of normal testosterone levels in the blood. The NHS advises no more than 25 mg a day from supplements unless a doctor advises it.

Vitamin K2 (MK-7)

200 µg MK-7 a day · Nu U Nutrition

Vitamin K contributes to the maintenance of normal bones. VitSync pairs it with vitamin D3. UK guidance sets a ceiling of 1 mg a day, five times this tablet. Not suitable if you take warfarin or another blood thinner.

Electrolytes

1 sachet in 500 ml water · Styrkr

Research suggests replacing sodium and potassium with fluid after hot or hard sessions supports rehydration. No authorised GB health claim. The sachet carries electrolytes and no vitamins. It includes magnesium, so count it alongside a magnesium tablet.

Folic acid

400 µg a day · Natures Aid

Folate contributes to normal blood formation. UK guidance is 400 µg a day for anyone who could become pregnant, from before conception until week 12 of pregnancy.

View on Amazon →

Vitamin B12

1000 µg sublingual a day · Solgar

Vitamin B12 contributes to normal red blood cell formation. Plant-based diets and older age are two common reasons B12 runs low. Only a small share of a large dose is absorbed, and UK guidance says 2 mg a day or less is unlikely to cause harm.

View on Amazon →

Vitamin B6

10 mg a day · HealthAid

Vitamin B6 contributes to normal energy-yielding metabolism. The NHS says not to take more than 10 mg of vitamin B6 a day in supplements unless a doctor advises it, so do not add a multivitamin that also contains B6.

Omega-3 (fish oil)

550 to 1100 mg EPA + DHA a day, by body weight · Nutravita

EPA and DHA contribute to the normal function of the heart, from 250 mg a day. Most useful in weeks with little oily fish. Not suitable if you have a fish allergy.

Ashwagandha (KSM-66)

350 mg a day · Peak Supps

Research suggests KSM-66 may support stress and sleep quality at 300 to 600 mg a day. No authorised GB health claim. Not suggested in pregnancy, while breastfeeding, or with thyroid medication.

Iron (ferrous fumarate)

14 mg a day · Nutrition Geeks

Iron contributes to normal formation of red blood cells and haemoglobin. VitSync never adds iron without flagging it for review with your GP or pharmacist first. Too much iron is harmful.

Creatine monohydrate

2 to 5 g a day, by body weight · Myprotein Creapure

Research suggests creatine may support short, high-intensity exercise. The authorised GB performance claim applies only from 3 g a day, for adults training hard. Not suggested in pregnancy.

View on Amazon →

Collagen peptides

5 to 15 g a day, by body weight · Bare Biology

Research suggests hydrolysed collagen taken alongside exercise may support connective tissue. No authorised GB health claim. A powder that mixes into coffee, smoothies or porridge.

View on Amazon →

Probiotics (multi-strain)

20 billion live cultures a day · Optibac

Research suggests some multi-strain probiotics may help gut health, though any effect depends on the strains and the amount. No authorised GB health claim. Not suitable if you are immunosuppressed.

View on Amazon →

CoQ10 (ubiquinol)

100 mg a day · Health Thru Nutrition

Research suggests CoQ10 plays a role in cellular energy production, and statins act on the same production pathway. No authorised GB health claim. Take it with food. Not suggested in pregnancy.

Vitamin A (beta-carotene)

7 mg beta-carotene a day · Vegavero

Vitamin A contributes to the normal function of the immune system. Your body turns beta-carotene into vitamin A as it needs it. UK guidance says no more than 7 mg of beta-carotene supplements a day, so do not add a second source. Not suitable if you smoke or have been exposed to asbestos. Not suggested in pregnancy.

Selenium

200 µg every other day (100 µg a day on average) · WeightWorld

Selenium contributes to the normal function of the immune system. UK soils are low in selenium, but more is not better once you have enough, so it only makes sense when your own intake is low. Skip it on days you eat brazil nuts.

Turmeric (curcumin)

1 tablet a day (190 mg curcumin) · Lamberts

Research suggests curcumin may ease muscle soreness after hard training, though the trials used several grams a day, far more than this tablet. No authorised GB health claim. The European Food Safety Authority sets an acceptable daily intake of 3 mg of curcumin per kg of body weight, so one tablet a day stays within it from 64 kg, and below that weight VitSync leaves turmeric out of your plan. The tablet has no piperine or other absorption enhancer, because an enhancer multiplies how much you absorb. Rare liver reactions have been reported. Stop and see a GP if you notice yellowing skin or eyes, dark urine or abdominal pain. Not suggested in pregnancy.

Myo-inositol

2 g a day (4 capsules) · Time Health

Research suggests myo-inositol may help with cycle regularity and insulin sensitivity in women with PCOS/PMOS, though no specific type or amount is recommended. No authorised GB health claim. No UK source establishes its safety in pregnancy, so VitSync does not suggest it once you are pregnant. It can stay in your plan while you are trying to conceive.

View on Amazon →

NAC (N-acetylcysteine)

600 mg a day · Prowise Healthcare

Research suggests NAC may support ovulation in women with PCOS/PMOS. The same review found no significant change in insulin or glucose measures. No authorised GB health claim. Not suggested in pregnancy.

View on Amazon →

Chromium

200 µg picolinate a day · Natures Aid

Chromium contributes to normal macronutrient metabolism and to the maintenance of normal blood glucose levels. UK guidance says around 25 µg a day should be enough, and there is not enough evidence on high doses, so do not add another chromium source.

Alpha-lipoic acid

600 mg a day · Best Naturals

Research suggests alpha-lipoic acid may support insulin sensitivity. No authorised GB health claim. Speak to your doctor first if you take diabetes medication. Not suggested in pregnancy.

View on Amazon →

Maca root

1200 mg a day (2 capsules) · The Natural Health Market

Research suggests maca may support energy and wellbeing around the menopause, from small trials. How it works is not established. No authorised GB health claim. Not suggested in pregnancy or while breastfeeding.

View on Amazon →

Vitex (chasteberry)

1000 mg a day · Nutrivity

Research suggests vitex may help with premenstrual symptoms. No authorised GB health claim. Avoid it during pregnancy, while breastfeeding, on hormonal contraception, or with any hormone-sensitive condition.

View on Amazon →

Berberine

1000 mg a day (2 × 500 mg capsules) · Fitimins

Research suggests berberine may support insulin sensitivity and metabolic markers, particularly in PCOS/PMOS. No authorised GB health claim. It changes how the body processes many medicines, including hormonal contraception, so VitSync always flags it for review. Talk to your doctor or pharmacist before starting, and never take more than the label says. Not suggested in pregnancy or while breastfeeding.

L-theanine

200 mg a day · Raw Powders

An amino acid found in tea. Research suggests it may support calm focus and sleep quality without sedation. No authorised GB health claim. Not suggested in pregnancy or while breastfeeding.
