Pros & Cons
✓ Pros
- Ashwagandha at 600mg — the highest evidence-backed clinical dose for sleep improvement
- Melatonin at 0.5mg — avoids grogginess and doesn't suppress natural production
- Arginine + Lysine HGH support is one of the most studied natural secretagogue combinations
- 5-HTP specifically increases slow-wave sleep proportion
- Addresses the HGH-fat loss connection
✗ Cons
- 60-day guarantee is short
- 5-HTP + melatonin should not be used with SSRIs or MAOIs
- Powder format requires nightly preparation
- HGH-boosting claims are modest compared to pharmaceutical approaches
Final Verdict
Renew is one of the most thoughtfully constructed sleep-metabolism supplements in our BuyGoods portfolio. Ashwagandha at 600mg, low-dose melatonin, and arginine/lysine HGH support all align with published clinical evidence. For adults who both sleep poorly and struggle with metabolic weight, Renew addresses both mechanisms simultaneously.
