OxySleep Review Singapore 2026: Does This Night Time Fat Burner Actually Work?

No, OxySleep does not burn meaningful fat while you sleep. EHP Labs markets OxySleep as a "nighttime shred" supplement, but the science is clear: fat loss requires a sustained caloric deficit and consistent training — no powder consumed before bed changes that equation. What OxySleep does offer is a decent sleep-support blend with L-Theanine, Ashwagandha, and Chamomile. However, Singapore gym-goers can get superior sleep quality and recovery support from locally stocked alternatives like Nutrex Lipo-6 Black Nighttime or GHOST Sleep — at a fraction of the price and with next-day delivery from Ultimate Sup.

What Is EHP Labs OxySleep?

EHP Labs OxySleep is a non-stimulant, powdered nighttime supplement from the Australian brand EHP Labs. It is designed to be mixed with water and consumed 20–30 minutes before bed. The product claims to serve two purposes simultaneously: promote deep, restful sleep while supporting overnight fat metabolism.

The "Collagen Night-Time Shred" version includes 5 g of bovine collagen peptides for skin, joint, and muscle recovery. OxySleep positions itself as the perfect bookend to the EHP Labs ecosystem — users take OxyShred during the day for fat burning and OxySleep at night for recovery.

The reality for Singapore buyers: OxySleep is typically priced at SGD 65–85 when imported, with inconsistent local availability and 5–10 day shipping from Australia. At that price point, you're paying a premium for a glorified sleep tea with added collagen — ingredients you can source separately for significantly less.

OxySleep Ingredient Breakdown: What Is Actually In It?

Understanding what OxySleep contains is the key to evaluating whether it justifies its premium price. The formula includes:

Sleep Support Blend: - L-Theanine — An amino acid found in green tea that promotes relaxation without drowsiness. Well-researched and effective at 100–200 mg doses - Ashwagandha (KSM-66) — An adaptogen that reduces cortisol and improves sleep onset. Clinically effective at 300–600 mg - Chamomile Extract — A traditional calming herb with mild sedative effects - Passionflower Extract — Shown to improve sleep quality in some studies - Magnesium — Essential mineral for muscle relaxation and sleep

"Fat Burning" Complex: - Green Tea Extract — Contains EGCG, which has modest thermogenic effects. However, the dose in OxySleep is typically undisclosed (proprietary blend), making it impossible to verify efficacy - Conjugated Linoleic Acid (CLA) — Research on CLA's fat loss benefits is mixed at best - Raspberry Ketones — No credible human studies support fat loss claims - Chromium Picolinate — May help regulate blood sugar, but does not directly cause fat loss

The verdict on ingredients: The sleep support side of OxySleep is genuinely useful — L-Theanine, Ashwagandha, and Magnesium are well-researched compounds that can improve sleep quality. The "fat burning" side, however, relies on ingredients with minimal evidence at the doses likely used. The proprietary blend label makes it impossible to verify whether any thermogenic ingredient is at an efficacious dose.

Does OxySleep Actually Burn Fat While You Sleep?

The short answer is no — at least not in any meaningful way. Your body does burn calories during sleep (your Basal Metabolic Rate accounts for 60–70% of daily calorie expenditure), but no supplement meaningfully accelerates this process without stimulants. And OxySleep deliberately contains zero stimulants to avoid disrupting sleep.

The thermogenic ingredients in OxySleep — green tea extract, CLA, raspberry ketones — require significantly higher doses than what a non-stimulant nighttime blend can provide to produce measurable fat oxidation. Studies on green tea extract, for instance, show thermogenic benefits at 400–500 mg EGCG per day — a dose that would likely cause insomnia if taken before bed.

What OxySleep actually does well: Improves sleep quality. And here's the connection EHP Labs exploits in their marketing — better sleep genuinely does support fat loss. Deep sleep optimizes growth hormone release, reduces cortisol, and improves insulin sensitivity. But you don't need OxySleep specifically to achieve better sleep. Any quality sleep supplement does this.

The Smarter Approach: Separate Sleep and Fat Loss

Rather than paying SGD 65–85 for an imported product that tries to do two things at once (and does the fat-burning part poorly), experienced lifters in Singapore use a two-product strategy:

For nighttime fat support: Use a dedicated, properly dosed nighttime thermogenic like Nutrex Lipo-6 Black Nighttime.

Nutrex Lipo-6 Black Nighttime is specifically engineered as a stimulant-free nighttime fat burner with clinically dosed ingredients. Unlike OxySleep's proprietary blend, Lipo-6 Black Nighttime discloses exact doses and uses research-backed compounds for overnight metabolic support. It is available at Ultimate Sup with next-day delivery across Singapore — from Tampines to Toa Payoh, Clementi to Changi.

For sleep quality: Use a premium, purpose-built sleep formula like GHOST Sleep.

GHOST Sleep is one of the most advanced sleep supplements on the market. It features clinically dosed ZMA (Zinc + Magnesium + B6), KSM-66 Ashwagandha, and additional ingredients specifically targeting sleep quality and recovery — without pretending to be a fat burner. The GHOST brand is synonymous with full label transparency, and every ingredient dose is clearly listed.

OxySleep vs Alternatives: Head-to-Head Comparison

Our analysis: The two-product approach (Lipo-6 Nighttime + GHOST Sleep) gives you superior, clinically dosed nighttime support for roughly the same total price as OxySleep alone — with the added benefits of full ingredient transparency and immediate local availability.

OxySleep Side Effects: What to Watch For

OxySleep is generally well-tolerated due to its stimulant-free formula, but Singapore users should be aware of these potential side effects:

• Morning grogginess: Some users report feeling groggy the next morning, particularly when first starting the supplement or at a full serving dose. Start with half a scoop to assess your tolerance
• Digestive discomfort: The collagen and herbal extracts may cause mild bloating or stomach discomfort in some individuals
• Allergic reactions: Check the label for bovine collagen if you have dairy sensitivities or specific dietary restrictions
• Interaction with medications: If you take sleep medications, anti-anxiety drugs, or blood pressure medication, consult your doctor before using OxySleep. The Ashwagandha and Passionflower may interact with these

Important safety note: Never operate a vehicle or heavy machinery after consuming OxySleep. It is formulated to induce sleepiness. Whether you live in Bukit Merah, Bishan, or Bedok, plan to take it only when you are ready for bed.

Who Should Consider OxySleep?

OxySleep makes sense in a narrow set of circumstances:

• You specifically want collagen + sleep support in one product
• You are already deeply invested in the EHP Labs ecosystem (OxyShred during the day)
• You prefer a hot-drink format supplement before bed
• You don't mind paying import prices and waiting for Australian shipping

For everyone else in Singapore — which is the vast majority of gym-goers — a locally stocked combination of Nutrex Lipo-6 Black Nighttime for targeted nighttime metabolic support and GHOST Sleep for premium sleep quality delivers better results at a comparable or lower total cost — with next-day delivery from Ultimate Sup.

Evidence-Based Tips for Better Sleep and Fat Loss in Singapore

Supplements aside, these are the habits that genuinely accelerate both sleep quality and fat loss for Singapore gym-goers:

1. Keep your bedroom cool: Singapore's tropical climate makes this challenging. Set your air conditioning to 23–25°C for optimal sleep temperature. This alone can improve sleep quality more than any supplement
2. Time your last meal: Finish eating at least 2 hours before bed. A high-protein snack (like casein protein or Greek yogurt) is fine, but avoid large meals that spike insulin
3. Limit screen time: Blue light from phones disrupts melatonin production. Use night mode or blue light glasses after 9 PM
4. Train consistently: Regular resistance training naturally improves sleep quality and metabolic rate. Whether you train at Virgin Active at Raffles Place or your neighbourhood HDB gym, consistency matters more than any supplement

Frequently Asked Questions

Does OxySleep actually help you lose weight?

OxySleep may indirectly support fat loss by improving sleep quality — poor sleep is strongly linked to weight gain and increased cortisol. However, OxySleep does not directly burn fat in any clinically significant way. Fat loss requires a sustained caloric deficit through proper nutrition and exercise. No nighttime supplement bypasses this fundamental rule.

Is OxySleep safe to take every night?

OxySleep is generally safe for healthy adults when used as directed. However, long-term nightly use may reduce the effectiveness of the sleep-promoting ingredients due to tolerance buildup. Consider cycling it — 4 weeks on, 1–2 weeks off — to maintain its effectiveness. Consult a healthcare professional if you have any underlying health conditions.

Where can I buy OxySleep in Singapore?

EHP Labs does not have an official Singapore distributor for OxySleep. Most purchases require importing from Australian or international retailers, with 5–10 day shipping times and potential customs fees. For locally stocked nighttime supplements with immediate delivery, explore the sleep and recovery range at Ultimate Sup.

What is the best nighttime supplement for Singapore gym-goers?

For dedicated nighttime metabolic support, Nutrex Lipo-6 Black Nighttime is the top recommendation available at Ultimate Sup. For pure sleep quality and recovery, GHOST Sleep is the premium choice. Both are available with next-day delivery across Singapore.

Can I stack OxySleep with OxyShred?

Yes, OxySleep is designed to be caffeine-free and can be taken at night alongside a daytime OxyShred regimen. However, if cost and local availability are concerns, you can achieve the same daytime-nighttime strategy by pairing JNX The Ripper (daytime) with Lipo-6 Black Nighttime (evening) — both locally stocked at Ultimate Sup.
