Dr. Brown's Anti-Colic Options+ Wide-Neck Glass Bottle, 5 oz

What we like and what concerns us

Caution

• The same extra polypropylene and thermoplastic-rubber vent parts and narrow tube to brush
• This SKU’s exact parts are unconfirmed

Good

• Glass body with a wider opening for the bottle itself
• Care instructions cover boiling, sterilizers and the dishwasher top rack
• The same mature vent design as the 4 oz bottle

What the evidence shows

• Safest Baby Bottles Sans Lead & Microplastics: Baby Registry Guide Mamavation (reporting testing by Eric Ritter, DetectLead.com), 2024-03-13

  Lists the Dr. Brown's Natural Flow Anti-Colic Options+ Narrow Glass Baby Bottle (not the wide-neck bottle) at 7 ppm lead, with 6 ppm on a second test. The article states that detected lead across the study was in bottle print or design but does not say which part was measured. Mamavation did not commission the testing, and no third-party lab confirmation or reporting limit is stated.

• Popular Baby Bottles With No Detected BPA, Lead, or Phthalates Consumer Reports, 2023-08-25

  Consumer Reports tested nine bottles including the Dr. Brown's Natural Flow Anti-Colic Options+ glass bottle and reported none had detectable BPA, lead or the eight federally regulated phthalates. Size and model are not stated; the wide-neck bottle is not named; the laboratory name and detection limits are not published. Page updated 2025-10-08.

These are independent sources we located and read. Manufacturer statements are not counted as evidence. How we weigh sources

Product identity

Dr. Brown’s product data feed lists this SKU with no barcode, so no UPC is recorded.

What touches the liquid

The body material is only one part of this product. Each part below is listed with what the maker says it is made of, and whether it reaches milk, formula or water.

Construction, coatings and base

Heat, sterilizing and dishwasher

The product page says the bottle is safe in the top rack of a dishwasher, in electric and microwave sterilizers or in boiling water. Dr. Brown’s says to boil the nipple for five minutes before first use, and to remove the vent system before warming the bottle or mixing by shaking because pressure changes can cause leaking. Microwave sterilizers are not permission to heat formula in a microwave, which the CDC says never to do. Dr. Brown’s gives no formula-preparation temperature for Options+ bottles.

Formula preparation: The CDC says very hot water, about 158°F / 70°C, is needed to kill germs when a baby is younger than 2 months, was born prematurely or has a weakened immune system. Standard preparation otherwise follows the formula maker's instructions. Never use a microwave, and bottles must be clean and sanitized. Pathogen control for higher-risk infants takes priority over any concern about particle release, so this page never suggests cooler water for those babies. CDC, Infant Formula Preparation and Storage.

Cleanability

Six parts are counted from the family-level component list: bottle, collar, nipple, cap, vent insert and reservoir tube. Dr. Brown’s says to use the included brush on the holes in the vent insert and the straw-like tube in the vent reservoir, to lay the vent insert on its side to drain, to let all pieces dry completely, and that hand pre-cleaning of the vent is recommended to prevent mold even though the parts are top-rack dishwasher safe. The vent adds narrow passages that must be cleaned by hand.

We show the facts and not a score. A CPSC recall in 2016 tied mold to an opaque, removable valve that held moisture, so hidden or narrow wet passages are worth checking on any cup.

What was tested, and what is only a claim

Independent testing of this exact product

None found as of September 30, 2026. That is missing evidence, not a finding against the product. Where a laboratory report is published, we will show the lab, method, batch, analyte, result, unit and detection limits, and we will never write a non-detect as zero.

Independent screening results for this product line

These are third-party results for the same brand and line, but the tested bottle is not confirmed to be this exact model or generation. They are screening results, most of them from advocacy testers using a handheld XRF instrument, which reads elements at the surface of a part. They are not accredited laboratory reports, they do not measure particles or migration into milk, and a non-detect is not zero.

What the manufacturer states

• BPA: 'BPA free.' Manufacturer disclosure Dr. Brown's

Background evidence about the materials (not this product)

These studies tested generic products, not this exact one. They show what is possible, and they don't show that this product releases anything or causes harm.

• Borosilicate glass: A glass bottle is a strong body choice, but read the rest of the fluid path before assuming a glass system has no plastic in it. Evidence for borosilicate glass
• Silicone: Silicone is practical and often preferred for nipples and soft interfaces. Findings on generic silicone are background and do not establish exposure or harm from any one product. Evidence for silicone
• Polypropylene (PP, resin code 5): Laboratory studies have measured temperature-dependent microplastic release from polypropylene infant feeding bottles. The clinical significance of infant ingestion at these levels remains uncertain. Evidence for polypropylene

Recalls and legal history

No recall of this exact product was located in the sources reviewed. A recall elsewhere in the category does not apply to it.

We searched the CPSC recall database by brand on September 30, 2026. For Dr. Brown’s (Handi-Craft): No bottle or cup recall. Recalls found concern Lovey pacifier holders (2018), bottle and dish soap (2017) and toys (1992). CPSC recall service

Legal history

• Miller et al. v. Handi-Craft Co. (Dr. Brown’s) (N.D. Cal., 4:24-cv-03782). Three consumers (Miller, Cortez and Wojciechowski) alleged that Dr. Brown’s bottles and cups released microplastics when heated. On April 29, 2025 the court dismissed the false-advertising claims because the plaintiffs had not shown that the microplastics released into warmed bottles were at unsafe levels; law-firm summaries cite the ruling as Cortez v. Handi-Craft, 2025 WL 1452561. On May 20, 2025 a plaintiff filed a notice of voluntary dismissal without prejudice. Closed May 20, 2025 by voluntary dismissal without prejudice, with no ruling on the merits of product safety. A dismissal without prejudice can be refiled, and we did not find a refiled case. This is legal history and not evidence about what the product releases.

What we still don't know

• Exact current materials for this SKU
• Exact-product laboratory data
• Dr. Brown’s does not say which vent parts contact the milk or give a formula-preparation temperature for these bottles

What would change our verdict

• An SKU-specific materials statement or independent laboratory report
• A change to the vent components
• A recall

Price

Prices and stock change often. Price and retailer availability play no part in the verdict.

• Microplastic release from the degradation of polypropylene feeding bottles during infant formula preparation, Li D et al., Nature Food (2020). Independent study Accessed September 30, 2026. Polypropylene infant feeding bottles released microplastics at values as high as 16,200,000 particles per litre; sterilization and high-temperature water significantly increased release. The authors estimated 14,600 to 4,550,000 particles per capita per day across 48 regions for infants up to 12 months, and called for assessing whether exposure at these levels poses a risk to infant health. It measured particle release and modelled intake, not health effects. Published November 2020 (Europe PMC). The abstract was read through Europe PMC because the journal page needs a cookie handshake.
• Migration of 35 Siloxanes from Silicone Food Contact Materials in China and Their Potential Exposure Assessment, Chen Y et al., Foods (MDPI) 15(8):1387 (2026). Independent study Published April 16, 2026. Accessed September 30, 2026. Tested migration of 35 siloxanes from 30 silicone food-contact products into food simulants under worst-case conditions and modelled exposure. Cyclic siloxanes exceeded proposed limits in several samples, particularly for children; D4 and D5 showed negligible risk while D3 raised potential concern, and 14 low-molecular-weight siloxanes (including D6 and L12) exceeded the threshold of toxicological concern across all age groups in the modelled scenarios. The products were silicone food-contact items sold in China, not the products on this page, and the exposure figures are modelled. Abstract read through Crossref.
