Quick Answer: By NIH Dietary Supplement Label Database records: both brands’ Fish Oil 1200 mg softgels state 360 mg omega-3 per softgel with a 2-softgel serving, but the directions differ: Nature Made says 2 softgels daily; Nature’s Bounty says 2 softgels two times daily. For vitamin D3 2000 IU (50 mcg), Nature Made’s tablet also lists 105 mg calcium; Nature’s Bounty’s is a softgel in soybean oil. For melatonin 5 mg, Nature Made’s tablet label says “for short-term use” and to consult a health care professional before use; Nature’s Bounty’s is a softgel. Only the Nature Made labels compared show a USP Verified statement. Unpaid; no winner.

How We Compared
Supplements do not need FDA approval before sale, so labels are the main source of information on contents. The NIH Office of Dietary Supplements Dietary Supplement Label Database (DSLD) records Supplement Facts panels and label statements. We compared three common products from each brand using DSLD records, noting each record’s details. Labels change; check the bottle you buy. FormulaCompare was not paid by either brand, lists no prices and does not name a winner. See also Kirkland vs Nature Made and Nature Made vs Thorne vs Garden of Life.
Fish Oil 1200 mg
Both Fish Oil 1200 mg labels state 360 mg of omega-3 per 1,200 mg softgel and list a 2-softgel serving (2,400 mg fish oil). The difference is in daily directions. The Nature Made label suggests adults take 2 softgels daily with a meal, and states the oil is purified to remove mercury. The Nature’s Bounty label directs adults to take two softgels two times daily, preferably with meals, which would be 4 softgels a day, and lists anchovy, herring, mackerel and sardine as fish sources. Its label warns to consult a doctor before use if pregnant, nursing, taking medications including blood thinners, or planning a procedure. Compare the omega-3 total per day you would actually take. See fish oil vs algae oil.
Vitamin D3 2000 IU
Nature Made D3 50 mcg is a tablet whose Supplement Facts also list 105 mg calcium. Nature’s Bounty D3 50 mcg (2000 IU) is a softgel with soybean oil, gelatin and glycerin. Both provide the same vitamin D amount; the form and added calcium differ. The NIH ODS sets the adult upper limit at 4,000 IU (100 mcg) a day from all sources. See our vitamin D guide.
Melatonin 5 mg
The Nature Made Melatonin 5 mg tablet label says it is for short-term use to help support sleep, to consult a health care professional before use, to take one tablet one hour before bedtime, and not to exceed one tablet daily unless recommended. Its Supplement Facts also list 80 mg calcium. Nature’s Bounty Melatonin 5 mg is a softgel with soybean oil and yellow beeswax. NCCIH notes melatonin may help with jet lag and some sleep-timing disorders, with small benefits for ordinary insomnia. A 2017 analysis by Erland and Saxena of 31 melatonin supplements sold in Canada found actual melatonin content ranged from 83% below to 478% above the label, which is one reason third-party verification is worth checking. See melatonin vs magnesium.
Third-Party Verification
The Nature Made fish oil and melatonin labels compared here carry a “USP Dietary Supplement Verified” statement. The Nature’s Bounty records we compared state “laboratory tested” and “guaranteed quality” but do not show a USP statement. Verification relates to quality testing, not to whether a supplement works for a health claim.
Putting It Together: Common Situations
The scenarios below summarize what the labels and guidelines cited on this page say. They are general information, not a personal treatment plan. Your pharmacist can check the choice against your other medicines, and your clinician can tailor it to your health history.
- Want fewer softgels per day: compare the daily directions, not just the per-softgel amount.
- Prefer vitamin D without calcium: the Nature’s Bounty D3 softgel lists vitamin D only.
- Want third-party verification: look for the USP mark on the specific bottle.
How to Read the Label Before You Buy
- Find the active ingredient first. Brand names are often reused across products with different ingredients. The active ingredient and its strength appear at the top of the Drug Facts or Supplement Facts panel.
- Check the “Uses” or labeled indication. A product is tested and labeled for specific uses. Using it for something else may not help.
- Read the “Do not use” and “Ask a doctor before use” sections. They list conditions and medicines where the product may be unsafe.
- Follow the directions for dose and duration. Note the maximum daily amount and how many days you can use it before checking with a clinician.
- Check for duplicate ingredients. Combination products can contain the same ingredient as something else you take, which raises the risk of taking too much.
- Note the “Stop use and ask a doctor” signs. These are the label’s own warning signs that a product is not working or is causing harm.
Common Mistakes to Avoid
- Taking melatonin nightly long term without discussing it with a clinician.
- Doubling up vitamin D from a multivitamin and a separate D3 product.
- Assuming two products with similar names are interchangeable. Compare the active ingredients and strengths instead of the packaging.
- Forgetting to tell your clinician. Keep a current list of every prescription, OTC medicine and supplement you take, and bring it to appointments and the pharmacy.
FormulaCompare does not recommend one brand over another. Use the sources below to check the details for the exact product in front of you, since formulas and labels can change.
How to Read These Labels
Start with the serving size and the daily directions, which can differ: two products with the same amount per softgel can lead to very different daily totals. For fish oil, compare the omega-3 line, not the fish oil weight. For vitamin D, note that labels may show micrograms, international units or both; 1 mcg equals 40 IU. Read the other ingredients for soy, gelatin, fish or calcium, and read any cautions about pregnancy, medicines or procedures. The DSLD records linked below show each panel as recorded.
Using Melatonin Thoughtfully
Melatonin is a hormone sold as a supplement in the US. Lower doses are often tried first, and the Nature Made label suggests consulting a health care professional before use. Keep melatonin out of children’s reach and ask a pediatrician before giving it to a child.
When to Talk to Your Doctor or Pharmacist
Talk with a clinician before starting supplements if you take blood thinners or other prescription medicines, are pregnant or breastfeeding, or have a medical condition. Ask before giving melatonin to children, and seek care for persistent insomnia, symptoms of too much vitamin D such as vomiting or confusion, or unusual bleeding.
