One clear reference for how much of each popular supplement to take, when, and in which form — based on the general evidence and public references. All amounts are typical ranges for healthy adults in 2026, not medical advice. Where it matters, the number to check on the label is the elemental or active amount, not the total compound weight.
Supplement dosage chart (2026)
| Supplement | Typical daily dose | When / how | Best form & notes |
|---|---|---|---|
| Creatine | 3–5 g | Any time, with water | Monohydrate (Creapure); loading optional |
| Magnesium | 200–350 mg elemental (supplement upper limit 350 mg) | Evening (for sleep/calm) | Glycinate for sleep; citrate for constipation; L-threonate for focus |
| Vitamin D3 | 600–2,000 IU | With a fatty meal | RDA 600–800 IU; upper limit 4,000 IU; routine testing not needed for healthy adults |
| Vitamin K2 | 90–200 mcg | With D3 / fat | MK-7 form; avoid if you take warfarin or another vitamin K antagonist (even 10 mcg/day can change your INR) |
| Omega-3 (EPA+DHA) | 250–500 mg combined | With food | Triglyceride form; check the EPA+DHA number, not fish-oil weight; doses above 1 g/day are linked to a higher risk of atrial fibrillation, so use higher doses (for example for high triglycerides) only with your doctor |
| Ashwagandha | 300–600 mg | With food, daily | KSM-66 or Sensoril standardized extract; short-term use (up to 3 months); avoid in pregnancy, while breastfeeding and with thyroid or autoimmune conditions; rare cases of liver injury have been reported |
| Lion’s mane | 500–1,000 mg | Any time | Fruiting-body extract (not just mycelium on grain) |
| Collagen peptides | 10–20 g | Any time (often with vitamin C) | Hydrolyzed type I & III for skin; joint products often use undenatured type II at a much lower dose (about 40 mg) |
| Zinc | 8–15 mg | With food | RDA 8 mg (women), 11 mg (men); upper limit 40 mg/day from food and supplements combined; long-term high doses can cause copper deficiency. Take apart from calcium/iron |
| Vitamin B12 | 500–1,000 mcg | Morning | Any form works (cyanocobalamin is the most studied); important for vegans and older adults |
| CoQ10 | 100–200 mg | With a fatty meal | Ubiquinol or ubiquinone; take with fat; may interact with warfarin and insulin, so ask your doctor if you take them |
| Berberine | 500 mg, 2–3×/day | With meals | Split dosing; can cause stomach upset; talk to your doctor first if you take diabetes or other medication; avoid in pregnancy and while breastfeeding (berberine can be harmful to newborns) |
| L-theanine | 100–200 mg | With caffeine, or for calm | Smooths caffeine jitters; non-sedating |
| Melatonin | 0.5–3 mg | 30–60 min before bed | Lower doses often work as well as high ones |
| Curcumin | 500–1,000 mg | With food | Poorly absorbed alone; piperine or bioavailable forms help, but the NIH warns these forms may harm the liver, so stick to the label dose |
| Vitamin C | 250–1,000 mg | With food, split if high | Upper limit 2,000 mg a day; doses above it can cause diarrhea and stomach upset |
Frequently asked questions
Should I take supplements with food?
Fat-soluble vitamins (D, K, E, A) and CoQ10 and omega-3 absorb best with a meal containing fat. Water-soluble ones (B, C) and creatine can be taken any time. Minerals like zinc and magnesium are gentler on the stomach with food.
What time of day should I take each supplement?
B12, creatine and CoQ10 can be taken in the morning with breakfast; calming ones (magnesium glycinate, L-theanine, melatonin) suit the evening. Consistency day to day matters more than the exact hour.
Can I take multiple supplements together?
Most combine fine. Notable exceptions: zinc competes with calcium and iron (separate them), and very high doses of one mineral can block another. When in doubt, spread minerals across the day.
Does more mean better?
No. For most supplements the benefit plateaus and higher doses only add cost or side effects (loose stools from magnesium/vitamin C, for example). Stick to the effective range.
How we put this together
These are typical ranges for healthy adults, last updated September 2026 against public references such as the NIH Office of Dietary Supplements and Examine.com, plus recent evidence like a 58-trial meta-analysis of omega-3 and cognitive function published in Scientific Reports (2025, low-to-moderate certainty) and a 2021 meta-analysis linking omega-3 doses above 1 g/day to atrial fibrillation. They are educational, not medical advice, and individual needs vary. If you are pregnant, take medication, or have a health condition, check with a doctor before starting.
